EXECUTIVE SUMMARY
Implementation of the Fort Collins Green Building Program has the primary goal of better aligning the built environment
with community goals of reduced carbon emissions, reduced energy use and reduced water use. The Green Building
Program framework is designed to support market transformation through a combination of regulatory and voluntary
elements. Green Building Program work over the past year has focused on developing a package of "green
amendments"for incorporation into the Fort Collins Building Code. This process has been led by staff,working closely
with stakeholders. The proposed amendments address opportunities with regard to resource efficiency, energy
efficiency,water efficiency, indoor and outdoor environmental quality,and buildings operation and maintenance. The
benefit cost analysis shows an overall net positive benefit compared with buildings constructed to current Code
requirements. The changes in Code requirements are projected to increase initial design and construction costs by
1% to 2% for residential buildings and 1% to 4% for commercial buildings. Among other benefits, the proposed
changes will provide energy, water and carbon savings compared with buildings constructed to current Code
requirements. Staff recommends the green amendments become effective January 1, 2012, with the exception of
the amendments establishing more stringent requirements for electrically heated buildings, to be effective upon
adoption.
BACKGROUND / DISCUSSION
Implementation of a Green Building Program was identified as a City Council priority during the 2010—2011 budget
process,with a primary goal of better aligning Fort Collins'built environment with community goals of reduced carbon
emissions, reduced energy use and reduced water use. Green building has a strong policy basis with the 2008
Climate Action Plan, 2009 Energy Policy and 2009 Water Conservation Plan.
The Utilities department is leading the effort of developing the Green Building Program in close collaboration with
Community Development and Neighborhood Services (CDNS).
March 1, 2011 -2- ITEM 28
The Green Building Program framework is designed to support market transformation through a combination of
regulatory and voluntary, market-driven elements. Green Building Program work to date has focused on developing
a package of"green amendments" for incorporation into the Fort Collins Building Code.
Green Amendment Development Process
After review of national model green building codes and standards, staff recommended to City Council at the July 13,
2010 Work Session that the project focus on developing a strategic selection of effective amendments to further
..green"the existing Building Codes. A majority of Council members supported the recommendation. Developing a
green amendment proposal was the focus of the project from July through November 2010. (The 2009 International
Codes(I-Codes) package, adopted by Council in September 2010, is the baseline for these amendments.)
The green amendment development process closely involved two Technical Review Advisory Committees, one
focused on the residential sector, the other on the commercial sector. Members were invited to participate based on
their technical and market expertise. Each committee typically met twice a month from May through November 2010.
Attachment 5 lists committee members. Attachment 12 lists comments from committee members on the green
amendment proposal. '
At the December 14, 2010 Work Session, staff presented a draft of the proposed green building practices under
consideration as amendments, along with four additional `options," a proposed implementation schedule and a
preliminary benefit cost summary. A majority of Council supported the direction and directed staff to finalize the
proposal and develop ordinances for adoption in March 2011 (Attachment 4).
Since the December Work Session, staff has refined details of the proposal, developed ordinances to amend the
Building Code, finalized the benefit cost analysis and reviewed the,proposal with boards and commissions.
Community Outreach
In addition to the community involvement via the technical review advisory committees,other community engagement
activities have included:
Web site. Information and opportunities to provide input have been available via the project web pages at
fcgov.com/gbp.
Public meetings. All advisory committee meetings have been open to the public. Meetings have been listed
on the project web pages and City web calendar.
Board,commission and other stakeholder meetings. Staff has presented multiple updates to City boards
and commissions and the Green Building Program Advisory Committee(Attachment 5), as well as to several
other stakeholder groups by request. Board and commission recommendations regarding adoption of the
green amendment ordinances are itemized below.
Public Open House. A public open house was held on November 17, 2010. The associated summary of
feedback was included in the December Work Session Agenda Item Summary.
Attachment 10 is a log of community engagement activities.
Green Amendments Proposal
The green amendments proposal has changed little from the draft package presented to City Council at the December
14,2010 Work Session."Amend ment-proposals-at-a-glance"—listing the proposed green building practices with brief
descriptions, for the residential and commercial sectors—are included as Attachments 1 and 2. Additional details
about each practice are available at the Green Building Program web pages, www.fcgov.com/gbp.
Proposal refinements made since the December Work Session are as follows:
Occupancy sensor controls of lighting in defined spaces. This measure was added to the commercial
amendment proposal, applicable to commercial and multi-family residential buildings. The proposed
amendment would require automatic reduction of connected lighting power by at least 50% in corridors,
enclosed stairwells, parking garages and other intermittently used spaces, when these spaces are
unoccupied. This measure was added as a low-cost practice for reducing electric energy use and carbon
emissions.
March 1, 2011 -3- ITEM 28
Certified wood. A requirement for sustainable forestry certification of wood products used in construction
was in the"option"category at the December 14, 2010 Work Session. A subset of this has been developed
as a proposed amendment. Tropical hardwoods, used in both residential and commercial projects,would be
required to have Forest Stewardship Council certification. Staff recommends this as an appropriate step for
regulation that will help to stimulate more attention and thought toward the"upstream impacts"of extracting
and processing building materials. Since tropical hardwoods are rarely used in entry-level projects,this does
not represent an added expense to the most cost-sensitive portion of the market.
Building envelope requirements for electrically heated residential buildings. The December 2010 draft
package included more stringent thermal requirements for attics,frame walls,windows,crawl spaces and air
leakage of electrically heated buildings, reflecting the significantly higher cost to heat with electricity versus
natural gas. The refinements increase stringency for basement walls, slab-on-grade foundations and mass
walls as well, to more comprehensively address electrically heated buildings.
Effective date for electric heat buildings amendments. Based on Council direction at the December 14,
2010 Work Session, the amended envelope requirements for electrically heated buildings are proposed to
become effective upon adoption of the amendment ordinances. The proposed effective date for the balance
of the amendments is proposed as January 1, 2012.
Other"options" discussed with Council at the December 14, 2010 Work Session, not included in the final proposal,
are:
Envelope requirements for gas-heated homes. Staff recommends that thermal requirements for gas-
heated residential buildings not be increased beyond those in the recently adopted 2009 I-Code package. In
staffs experience, the more important next step in achieving thermal envelope efficiency is increased focus
on the details necessary to install components so they deliver rated performance. This is what drives the
amendments regarding insulation installation standards and installation procedures forwindows,skylights and
doors, as well as plans for training and developing field guides that clearly illustrate important thermal
envelope details. Staff expects to recommend that the next steps in thermal envelope requirements be taken
with the 2012 I-Codes package, currently planned for adoption in 2013.
Renewable energy. Staff recommends that renewable energy requirements remain in the voluntary,market-
driven realm at this time, because they represent a much larger increase in first cost than anything else
included in the proposal. For example, the installed cost of a typical solar electric system for residential use,
three kilowatt peak capacity, is on the order of$18,000. This would add about 7%to the cost of the residential
prototype house used for the benefit cost analysis, far greater than the total estimated cost increase
associated with the green amendment proposal as a whole (see "Financial/Economic Impacts" below). It
would produce about half of the electrical energy used by a typical customer. The average cost of the
electricity produced by the photovoltaic system (over a 20-year life, with a 7%discount rate), would be about
$0.40 per kilowatt-hour, compared to the current Fort Collins Utilities' residential rate of about$0.08/kWh.
The same-sized system on the commercial prototype would add about 1% to the cost of the building, while
meeting only about 3% of annual electrical needs. The $18,000 cost assumes no tax incentives or utility
rebates.
Higher performance requirements for larger homes. Staff recommends that variable green requirements,
based on house size, not be incorporated as part of the Building Code. Though a case can be made that
larger homes built to the same standards as smaller homes have a larger environmental footprint,preliminary
discussion at stakeholder meetings suggested that mandating stricter standards would be very controversial.
This approach is incorporated in the national,voluntary green building rating systems as well as the updated
ENERGY STAR® Homes standard that will be effective in January 2012. As other portions of the Green
Building Program develop,the City may offer increasing levels of recognition and/or incentives based on some
of these programs. Staff recommends gaining more experience through the voluntary approaches before
addressing this through a Code requirement. Attachment 7 provides data on the sizes of single-family homes
built in Fort Collins from 2005 through 2010.
Proposed ordinances have been developed to incorporate the green practices as amendments to the existing Fort
Collins Building Codes. T able 1 itemizes the specific Codes that will be amended and how they apply to different
building types.

Green Building Practices Not Included in Proposed Amendments
Green building practices that were considered in the development process but not included in the proposed
amendment package are listed in Attachment 6. Many of these practices are already addressed to some extent by
current Fort Collins Codes or will be promoted through voluntary Green Building Program elements (education,
training, recognition, incentives). Some will likely be reviewed in the future for inclusion in other parts of the City Code
or the Land Use Code.
Implementation Planning
Staff recommends a high level of support be provided for a smooth transition to the new Code requirements. A
proposed effective date of January 1, 2012 for all but the electric heat amendments was supported by Council at the
December 14, 2010 Work Session. The period between adoption and implementation provides time to detail
certification requirements and testing protocols, develop new submittal forms and templates associated with the
amendments, develop field guides illustrating acceptable techniques for compliance, and provide training for
contractors and enforcement staff.
Utilities and CDNS will closely work together in support of a successful transition. Table 2 outlines general City
responsibilities, by department:

FINANCIAL / ECONOMIC IMPACTS
Benefit Cost Analysis
A benefit cost analysis of the proposed green amendments considers benefits and costs related to owners/occupants,
the building sector and the community/ecosystem. The report, Attachment 3, describes the methodologies and
assumptions used in the analysis.
Results show:
• The proposed green amendments align with Fort Collins community goals embodied in the Energy Policy
(2009), Water Conservation Plan (2009) and the Climate Action Plan (2008), while providing a variety of
benefits for building owners and occupants.
• Costs incurred at the individual, building sector or community/ecosystem levels can produce benefits at
multiple levels.
• Near-term cost increases, associated with the design and construction of a building project, are balanced by
recurring benefits delivered over the life of the building. Other community-level benefits improve the economic
picture.
• Initial cost increases projected for building projects are not insignificant, but represent relatively small
percentage increases(1%to 4%); these are within typical variance ranges for construction. It is anticipated
that increased design and construction costs incorporated in this analysis will decrease as contractors gain
experience and infrastructure matures. There are exemplary green,h ig h-performance buildings in Fort Collins
that deliver a strong array of benefits with little or no cost increase compared with conventional construction.
• Reductions of energy,water and carbon are projected on the order of 5%to 10%for residential projects and
20% to 30%for commercial projects.
• The proposed green amendments do not provide a quick"payback"for building owners,based on a traditional
view of utility savings compared with increased design and construction costs.
• Increases in Code enforcement time are estimated on the order of 45%for residential projects and 25% for
commercial projects, requiring additional staffing.
Using generally conservative assumptions and the elements quantified to date,total benefits are projected to exceed
total costs, with a benefit-to-cost ratio of 1.3.
There are direct costs to the City in two areas:
• Development of support materials and training. These pre-implementation phase costs, estimated at
$100,000, will primarily be incurred in 2011. They are one-time costs. The planned materials and training,
discussed above under "Implementation Planning," will support a smooth transition to the new Code
requirements. Funds covering these needs have been appropriated in the Utilities 2011-2012 budget.
• Enforcement. The amendments will represent increased enforcement staff time. This cost has been
accounted for in the benefit cost analysis. Council recently allocated funding from Amendment 2B revenues
to cover increased enforcement staffing, for 2011 and 2012. This means that, in this time frame, building
permit fees will not increase as a result of the green amendments.
Appraisal/valuation
The benefit cost analysis documents ranges of increased initial design and construction costs associated with the
proposed green amendments for prototypical buildings. Staff is aware of potential appraisal and underwriting
challenges related to these cost increases. Residential appraisal procedures have become much more tightly
regulated since the recent mortgage foreclosure crisis, leaving appraisers little latitude in recognizing non-standard
features. These challenges can be real for any building containing features which have not yet been widely
implemented in the market. The challenges are not specific to Fort Collins or green building;they are national in scope
and part of the challenges buyers face when trying to secure financing for a home they wish to build or buy.
Efforts are underway at the state and national level to modify regulations to make it possible to more readily recognize
the benefits of green features in the appraisal process. "Green fields" were recently added to the Multiple Listing
Service database serving Northern Colorado. Education and public awareness building in Fort Collins will also help
to increase market recognition of these benefits.
March 1, 2011 -6- ITEM 28
The proposed green amendments are not unlike other Code updates that have occurred on a regular basis for many
years. Typically, Code updates include increased requirements related to health, safety and energy, many of which
are not immediately recognized by the marketplace. The most recent Fort Collins Code update went into effect in
October 2010 with, for example, increased prescriptive insulation requirements for single-family homes. Appraisal
and valuation issues have not generally been an issue for previous Code updates in Fort Collins.
Development trends
Some stakeholders have expressed concern that adding new regulations to construction in Fort Collins may drive
development to nearby communities with less stringent building codes. This, in turn,could potentially undermine the
green intent of the proposed amendments by increasing vehicle miles traveled and associated environmental effects.
These stakeholders have pointed out that construction activity is currently very low in Fort Collins and that the
proposed amendments may cause a further decline.
Council members asked staff to provide information on development trends in Fort Collins, regionally and nationally
to help better understand these dynamics. Relevant data is summarized in Attachment 8. Construction activity in Fort
Collins,while currently low, is not as low as comparable Northern Colorado communities; it has actually outperformed
the comparables in 2008 to 2010.
As indicated in the benefit cost analysis, concerns about higher initial costs associated with increased Code
requirements are balanced by a variety of other factors. A higher profile for green building can increase a community's
competitive advantage, attracting development and business. The U.S. Green Building Council outlines a business
case for green building for commercial building owners(Attachment 9). This information suggests that green building
is a competitive differentiator, mitigates risk, attracts tenants, is cost-effective and increases rental rates. All of these
factors bolster the City's economic health.
ENVIRONMENTAL IMPACTS
The proposed amendments provide a variety of environmental benefits. Though construction will continue to have
environmental impacts, buildings meeting the proposed amendments will have less impact than buildings built to the
current code.
• Energy savings.These are projected at 5%to 10%of annual use for residential construction and 24%to 36%
for commercial construction.
• Water savings. These are projected at 5%to 10% of total annual use for residential construction and about
20% of indoor water use for commercial construction. Less water use translates to reduced wastewater
treatment needs.
Carbon reduction.These are projected at 5%to 10%of annual emissions for residential construction and 17%
to 26% for commercial construction.
• Landfill diversion. The construction waste recycling amendment will divert materials from the landfill.
Enhanced durability anticipated to result from several amendments will reduce maintenance requirements and
associated waste disposal. These benefits have not been quantified.
• Sustainable forests. The certified wood amendment will require tropical hardwoods used in construction
projects to be obtained from sustainably managed forests. Benefits will be"upstream,"in the areas from which
the lumber is harvested, rather than in Fort Collins. Impacts have not been quantified.
More information is provided in the benefit cost analysis report(Attachment 3).

BOARD / COMMISSION RECOMMENDATION
The Green Building Team gave presentations to boards and commissions regarding the green amendments proposal
during February 2011. Excerpts of minutes reflecting each boards'discussion on this topic are included in Attachment
11.(Recommendations from boards and commissions,that are received after this Agenda Item Summary is submitted
will be included in the Council meeting "read before" packet on March 1)
The recommendations from boards and commissions to which presentations were made prior to submission of this
Agenda Item Summary are as follows:
• Electric Board (February 2) recommended adoption (5-1)
• Affordable Housing Board(February 3)recommended against adoption(5-1). Additional recommendations:
• Ask that City Council consider making these proposed changes to the Code voluntary (rather than
mandatory code) with a reward of reduced fees or approval delays if the project meets stringent green
building Code guidelines.
o If Council declines to make these Codes voluntary, and instead adopts them as part of Code, ask that
Council consider waiving these requirements for projects that qualify as Affordable Housing.
o Alternatively, ask that Council consider funding the Affordable Housing Fund an additional amount
($50,000) that would be set aside just for"green" projects, so that qualified "green" Affordable Housing
projects could apply for and use these funds to offset the increased costs in the new Code.
• Landmark Preservation Commission (February 9) recommended adoption (6-0)
Presentations are scheduled to the following boards and commissions prior to the March 1, 2011 Council meeting;
their recommendations will be forwarded to Council in the "read-before" packet:
• Economic Advisory Commission (February 16)
• Natural Resources Advisory Board (February 16)
• Water Board (February 17)
• Building Review Board (February 24)

Benefits and Costs of
Proposed Building Code Green Amendments
Executive Summary
The intent of the benefit cost analysis of the proposed building code green amendments is to consider
benefits and costs related to owners/occupants, the building sector and the community/ecosystem.
Results show:
• The proposed green amendments align with Fort Collins community goals embodied in the Energy
Policy (2009), Water Conservation Plan (2009) and the Climate Action Plan (2008), while
providing a variety of benefits for building owners and occupants.
• Costs incurred at the individual, building sector or community/ecosystem levels can produce
benefits at multiple levels.
• Near-term cost increases, associated with the design and construction of a building project, are
balanced by recurring benefits delivered over the life of the building. Other community-level
benefits improve the economic picture.
• Initial cost increases projected for building projects are not insignificant but represent relatively
small percentage increases (one to four percent); these are within typical variance ranges for
construction. It is anticipated that increased design and construction costs incorporated in this
analysis will decrease as contractors gain experience and infrastructure matures. There are
exemplary green, high-performance buildings in Fort Collins that deliver a strong array of benefits
with little or no cost increase compared with conventional construction.
• Reductions of energy, water and carbon are projected on the order of five to ten percent for
residential projects and on the order of 20% to 30% for commercial projects.
• The proposed green amendments do not provide a quick "payback" for building owners, based on a
traditional view of utility savings compared with increased design and construction costs.
• Increases in code enforcement time are estimated on the order of 45% for residential projects and
25% for commercial projects, requiring additional staffing.
Using generally conservative assumptions and the elements quantified to date, total benefits are
projected to exceed total costs. A benefit-to-cost ratio of 1 . 3 is projected.
1. Introduction
Staff has developed proposed building code green amendments for City Council consideration. One
package of amendments addresses residential buildings, the other addresses commercial buildings. Staff
worked with a consultant, The Brendle Group, to develop a benefit cost analysis for the proposed
amendments.
The charge from City Council to staff regarding "greening" the Fort Collins building code was to
develop amendments that align with City goals around reducing energy use, water use and carbon
emissions, while also addressing other green building opportunities such as improved indoor air quality.
Buildings complying with the proposed amendments will deliver additional benefits compared with
buildings complying with the current code. The changes also will, for many projects, mean higher initial
costs. This analysis has been prepared to support Council' s decision-making process by outlining and

quantifying, where feasible, the range of benefits and costs associated with the proposal. Benefits and
costs are approached from a "triple-bottom-line" perspective, reflecting social, economic and
environmental impacts .
This report describes categories of benefits and costs related to green building, the analysis methodology
and results. Appendices provide additional detail. "Amendments-at-a-Glance" summaries of the
proposed packages and in-depth descriptions of each individual amendment (including benefits and
costs) are available on the Building Code Green Amendments web page at www. fcgov.com/lzbp.
There are many ways to design and build buildings. Tabulating benefits and costs is an imprecise
science. In developing the analysis, a generally conservative approach was taken so that benefits would
not be overstated and costs would not be understated.
2. Benefit Cost Categories
Figure 1 illustrates categories of benefits and costs related to green building. They occur at three inter-
related scales, represented by concentric circles:
• Individual. A specific project, where the impacts are traced to an owner or tenant.
• BuildingSector.ector. The building services industry, which includes design and construction
professionals and product suppliers.
• Community/Ecosystem. Local, regional or global costs or benefits.
Costs are shown on left-hand side of the diagram, benefits on the right-hand side. Each category is
described below.

Cost Categories (see Figure 1)
• Individual, Near-term. Increased, one-time cost to design/build a building. The "$" signs get smaller
in the graphic to represent decreasing costs as the industry moves along a prototypical learning
curve. The varying size of the "$" signs also represents the range of initial cost increases, depending
on the starting point of the construction team.
• Building Sector, Training. Building sector costs related to training on new construction techniques
and compliance requirements. These are near-term costs that will be amortized over many projects.
• Building Sector, Other. Other building sector costs, such as buying new tools or obtaining and
maintaining new certifications. These are primarily near-term costs that will decrease over time
based on market development, competition and adaptation.
• Community, Training + Support Materials. Pre-implementation phase (prior to the January, 2012
effective date of the green amendments in) costs borne by the City cover the development of support
materials, staff training and subsidization of industry training.
• Community, Enforcement. Increased implementation costs related to the City' s day-to-day
enforcement of the green amendments. These could be borne by building owners (through building
permit fees) or by the community as a whole or a combination.
• Community, Quality Assurance + Evaluation. Implementation costs, borne by the City, for on-going
quality assurance and program evaluation.
Benefit Categories (see Figure 1)
• Individual, Utility Savings . Lower utility costs for electricity, natural gas, water and wastewater.
• Individual, Maintenance Savings. Some green amendments will result in reduced maintenance costs,
which will accrue to the occupant and/or owner of the building.
• Individual, Building Valuation. Green buildings are expected to command an increased value in the
marketplace compared with conventional buildings.
• Individual, Occupant Health + Productivity. The green amendments will lead to improvements in
indoor environmental quality (improved thermal comfort, improved indoor air quality) . These, in
turn, will improve occupant health and productivity.
• Building Sector, Jobs. The building sector will realize an increase in job activity for a given amount
of construction activity. The green amendments support the expansion of related infrastructures,
higher-level contractor skills, increased demand for green services and increased demand for green
products.
• Building Sector, Investment. The building sector will realize increased investment through the
supply chain development cycle. Beyond the direct job impact described above, direct suppliers,
indirect suppliers, products and materials vendors will develop and mature, resulting in reduced cost
premiums over time.
• Community, Economic Health. The green amendments support the community' s values, pride and
identity as a vibrant, environmentally conscious place to live. The community' s reputation as such
also supports economic health as by attracting outside investment and local economic development.
Progressive public policy has been shown to increase activity in many instances related to green
building and clean energy.

• Community, Infrastructure. Direct benefits of green building (reduced energy use, water use and
waste) have indirect impacts on community infrastructure requirements, such as extending the life of
existing investments in power supply, water supply and landfills.
• Community, Carbon Reduction. The direct results of green building (reduced energy use, water use
and waste) contribute directly to the community' s goals to reduce carbon emissions.
• Community. /system, Environment. In addition to carbon reduction, the green amendments
reduce environmental impacts associated with construction (resource use, waste, outdoor
environmental quality).
3. Analysis and Results
Benefits and costs have been quantified where feasible. They were assigned value using either of two
approaches :
• Component analysis. The impacts of each proposed amendment were analyzed to develop building-
specific benefits and costs, and code enforcement costs.
• Community-scale analysis. This approach, which included applying the results of research
performed elsewhere to Fort Collins, was used to estimate benefits related to building valuation,
occupant health and productivity, economic health and carbon reduction.
Other types of costs and benefits have not been quantified. Tables 1 and 2 show generally how each
category was handled in the analysis. More information follows in Sections 3 . 1 and 3 .2 .
The quantified elements have been compared to develop a benefit-to-cost ratio. It must be emphasized
that the benefit cost analysis is approximate, reflecting uncertainties in accurately quantifying both
benefits and costs.
The analysis focused on new construction. Existing building scenarios (alterations and additions, from
minor to very large) are too varied to be analyzed with this approach and timeframe. Also, many of the
proposed amendments do not apply to existing buildings or apply only in part (see "Applicability"
information in the "Amendments-at-a-Glance" summaries and the detailed description of each proposed
practice at www.fcgov. com/gbp).

3 . 1 Quantified Elements
Costs and benefits quantified via component analysis and community-scale analysis are described in the
Subsections 3 . 1 . 1 and 3 . 1 .2, respectively. Results are summarized and combined to calculate the benefit-
to-cost ratio in Subsection 3 . 1 .3 .
3. 1 .1 Component Analysis
Primary benefits and costs of the proposed green amendments for typical projects were quantified via
component analysis. Primary benefits are the reduced utility costs (electricity, natural gas, water and
wastewater). Primary costs are increased design and construction costs. The analysis reflected each
proposed amendment.
Important aspects of the analysis include:
• Benefits and costs are generally presented as ranges. This reflects that, for each proposed code
amendment, there are often multiple ways to comply; different contractors have a range of
experience and a range of costs for products and labor; there is uncertainty in estimating benefits and
costs of building projects.
• It is assumed that all increased first costs are passed directly to the owner of the building.
• "Cost" represents retail cost
• Data sources included architects, builders, trade specialists, product suppliers, staff experience,
energy modeling, other studies and analyses.
• Generally, conservative values have been chosen so as to not overstate benefits or understate costs.
Building-specific benefits and costs were developed for two prototypical buildings to which the majority
of the proposed amendments could be applied:
• Residential
- 1 ,600 square foot ranch over full basement (3 ,200 sf conditioned area)
- Natural gas heat
- $250,000 sales price, financed with a 6%, 30-year mortgage
- $2,600 annual utility cost
• Commercial
- 15 ,000 square foot office building, two stories
- Natural gas heat
- $ 162 per square foot construction cost ($2 .4 Million)
- $ 14,000 annual utility cost
The team recognizes that these are limited examples of the many types and sizes of buildings in the
market. These were developed to provide a more tangible reference for benefits and costs.
Benefits and costs associated with each proposed amendment are provided in Appendix 1 (residential)
and Appendix 2 (commercial) . Totals are shown in Tables 3 and 4, representing the set of applicable
green building practices for each project. The base case is the prototype project meeting current Fort
Collins code requirements .

Energy Savings -- 5% to 10 % of annual use
Water Savings -- 5% to 10 % of annual use
Carbon Savings -- 5% to 10% of annual emissions

Energy Savings -- 24% to 36% of annual use
Water Savings -- 20% of annual indoor use
Carbon Savings -- 17% to 26% of annual emissions
Enforcement costs were also estimated using component analysis. The Building Official evaluated the
impact of each proposed amendment on the time required for plan review, field inspection and
administrative tasks. Estimated increases versus the workload associated with the existing codes are on
the order of 45% for residential projects and 25% for commercial projects (see Appendix 3 for more
detail). The increased workload translates to an additional 1 .5 full-time equivalent positions in the
Building Department, valued at approximately $ 158K annually for salary and benefits.
3. 1 .2 Community-Scale Analysis
The consultant reviewed published regional and national studies of green building benefits and costs
relative to individuals as well as communities, economies and ecosystems . The consultant also spoke
with City economic development staff. This research indicates there are many benefits associated with
green, high-performing buildings, including energy and environmental awareness, economic health,
community pride and the opportunity to hedge against utility rate increases.
Based on the available information, the consultant quantified four benefits with sufficient confidence to
inform the Fort Collins analysis. These are summarized here; additional information is provided in
Appendix 4. Note that all of these analyses should be considered "order-of-magnitude" in nature.
Because there are many uncertainties when applying the research to the green amendments proposal,
conservative assumptions have been made.
• Building valuation. Studies show that labeled "green buildings" command higher value in the
marketplace than their conventionally built counterparts. For this analysis, a one-percent increase in
valuation was applied.
• Occupant health and productivity. Research has shown that occupants of green buildings tend, on
average, to be healthier and/or more productive. The consultant extrapolated the research results to
estimate the 20-year net present value of health cost savings for occupants of residential buildings
8of11
ATTACHMENT 3
($28 per person) and increased productivity of commercial building occupants ($4. 61 per square
foot).
• Economic health. This term reflects increased local economic activity associated with increased
construction spending. It ties to three of the benefit categories illustrated in Figure 1 : Building
Sector, Jobs; Building Sector, Investment; and Community, Economic Impacts. Based on
conversations with City economic development staff, the consultant used an economic multiplier of
0. 5 of the increased construction cost. In other words, 50% of the increased cost attributed to the
green amendments is re-injected into the local economy
• Carbon reduction. Carbon savings are the only ecosystem benefit quantified in this analysis. Though
carbon is not yet widely traded in the United States, a variety of research provides a basis to estimate
the likely market value of savings. The consultant used a value of $20 per metric ton of carbon
savings.
3. 1 .3 Benefit-to-Cost Ratio
The benefits and costs that have been quantified can be totaled and compared. This was done using the
following approach and assumptions :
• A net present value approach was used to account for the stream of future benefits (such as annual
utility savings and improved occupant productivity) and compare them against costs incurred when
the building is built. Consistent with many building analyses, a term of 20 years was used. A 7%
discount rate, including 2% general inflation of goods and services, was assumed.
• Utility rates are assumed to stay constant at today' s values.
• Construction activity is assumed to be 200 new homes and 10 new commercial office building
projects per year (other commercial construction is not reflected in the analysis). Actual construction
activity is difficult to predict; the analysis model is readily scalable.
Tables 5 and 6 summarize the data reported above, as extrapolated to the community scale using the
construction activity assumptions in the previous bullet. These summaries represent the benefits and
costs associated with one year of construction.
Table 6 includes a roughly estimated cost ($ 100K) associated with training and development of support
materials prior to the effective date of the green amendments.
It is important to recognize that the quantitative analysis only tells part of the benefits and costs story.
Non-quantified aspects are discussed in the next section.

Given the many assumptions underlying the data presented in this section, the ratio of benefits to costs
for the proposed green amendments is $2 .23 Million to $ 1 . 76 Million, equaling 1 .3 .
3.2 Non -Quantified Elements
As described above, not all benefits and costs have been quantified. Table 2 lists those that were not and
includes brief comments for each. Some of these categories could be quantified with more information.
Others are more inherently qualitative, such as the benefits of a darker night sky.
Non-quantified benefits associated with each proposed amendment are listed under the "People" and
"Environment" benefit headings in the detailed descriptions available at www.fcgov. com/gbp. Many of
these benefits can be grouped into categories such as improved comfort (from improved building
envelopes and better-performing heating and cooling systems), better indoor environmental quality
(from building materials with lower pollutant emissions, safer combustion appliances, whole-house
ventilation, building flush-out, acoustic requirements), improved outdoor environmental quality (Dark-
Sky lighting fixtures), and conservation of resources for future generations (energy-efficiency measures
and construction waste recycling) . Some of these benefits will accrue to the individual owner or
occupant while others are community benefits.
Non-quantified costs primarily reflect the process of change from conventional practices.

4. Discussion
The proposed building code green amendments involve many types of benefits and costs . This analysis
suggests:
• Benefits and costs can be associated with individuals, the building sector, the community and
ecosystem. Costs incurred at one level can produce benefits at multiple levels .
• Near-term cost increases, associated with the design and construction of a building project, are
balanced by recurring benefits delivered over the life of the building. Other community-level
benefits improve the economic picture.
• Initial cost increases projected for building projects are not insignificant but represent relatively
small percentage increases (one to four percent); these are within typical variance ranges for
construction.
• The proposed green amendments align with Fort Collins community goals embodied in the Energy
Policy (2009), Water Conservation Plan (2009) and the Climate Action Plan (2008), while
providing a variety of benefits for building owners and occupants.
• The proposed green amendments do not provide a quick "payback" for building owners, based on a
traditional view of utility savings compared with increased design and construction costs.
• The relative magnitude of utility savings and associated carbon reduction is considerably higher for
commercial buildings than for the residential sector. The commercial opportunities are greater
because building code has lagged in addressing key opportunities in the areas of building envelope
and commissioning.
• The three largest projected benefits are utility savings, economic health gains and higher building
valuation. Making this latter benefit a reality will require education of the market and progress in
removing barriers in the appraisal and underwriting processes.
Based on the elements quantified to date, total benefits are projected to exceed total costs.
While there are uncertainties in accurately quantifying both benefits and costs, the intent of this analysis
was to capture the essence of the benefits and costs within the scope, budget and timeframe of this
proj ect.
To avoid overstating benefits or understating costs, the analysis team has generally made conservative
assumptions. For example, building cost increases used in the analysis generally reflect the current
situation in Fort Collins, in which some of the proposed amendments address practices for which many
contractors have little experience and the infrastructure to efficiently implement the practices is not well
developed. Experience with past code changes suggest that many costs are likely to significantly
decrease over time, as contractors move up the learning curve and infrastructure matures. It should also
be noted that there are exemplary green, high-performance buildings in Fort Collins that deliver a strong
array of benefits with little or no cost increase compared with conventional construction.

Community-Scale Analysis
To provide insight to complement the component analysis approach, the consultant reviewed published
regional and national studies of green building benefits and costs relative to individuals as well as
communities, economies and ecosystems. The consultant also spoke with City economic development
staff. This yielded additional information that supported the community-scale analysis.
The community-scale benefits and costs are challenging to quantify, given the range of variables and
factors involved. Based on the available information, the consultant felt that four benefits could be
quantified with sufficient confidence to inform the Fort Collins analysis: building valuation, occupant
health and productivity, economic health, and carbon reduction. This appendix provides information
about data sources and how the information they provided was applied to estimate each of these
benefits.
The studies used in this analysis represent often-referenced sources (e.g. , by U. S . Green Building
Council) and/or sources referred through the green amendment development project (by members of the
advisory committees and other stakeholders) on green building benefits and costs. They do not represent
an exhaustive literature search.
Because there are many uncertainties when applying the research to the green amendments proposal,
conservative assumptions have been made and the numbers generated through this approach should be
considered "order-of-magnitude" in nature.
1. Building Valuation
Two green building studies were used to inform the residential valuation analysis:
• ICF Incorporated (Nevin and Watson), Evidence of Rational Market Values for Home Energy
Efficiency, The Appraisal Journal, October 1998 .
• Earth Advantage Institute (Ann Griffin), Certified Home Performance: Assessing the Market
Impacts of Third-Party Certification on Residential Properties, May 2009.
The first study' s findings indicate a $20 increase in market value for every $ 1 in annual energy savings.
The second study reports three to five percent higher selling price for homes with a third-party
sustainable certification such as ENERGY STAR and LEED for Homes.
For the Fort Collins analysis, the method in the first study was used to calculate a one percent increase
in home value based on the estimated utility savings. This method is more conservative than the second
study and also reflects that no third-party certification is associated with the proposed amendments.
Two green building studies were used to inform the commercial building valuation analysis:
• McGraw-Hill - Business Benefits of Green Buildings SmartMarket Report: Building & Occupant
Performance Driving Green Investment in Existing Commercial Buildings, November 2010
• University of California Energy Institute (Eichholtz, Kok, and Quigley), Doing Well by Doing Good
— Green Office Buildings, August 2006
1
ATTACHMENT 3
These studies indicate that green high-performing buildings typically have increased value in the
marketplace compared with their conventionally built counterparts. According to the first study, green
buildings have a five percent higher valuation and occupancy rates, and one percent higher rental
incomes. The second study reports two percent higher rents; when adjusted for occupancy-level, this
translates into six percent higher effective rents.
Because the proposed green amendments do not address all of the green attributes in the buildings
studied and the regulatory approach does not include visible building labels, a conservative value of 1 %
was chosen to represent the increase in valuation.
Building valuation benefits tabulated in the benefit cost report were derived by applying the one percent
increase to the values used for the prototype buildings, multiplied by numbers of projected new
buildings. These benefits are considered one-time occurrences.
2. Occupant Health and Productivity
These studies were used to value occupant health and productivity:
• US Green Building Council (Gregory Kats), Greening America 's Schools — Costs and Benefits,
October 2006.
• Gregory Kats, The Costs and Financial Benefits of Green Buildings - A Report to California 's
Sustainable Building Task Force, October 2003 .
Overall, the studies were conducted on buildings that featured indoor air quality improvements related
to ventilation and controls for temperature and pollutant sources.
The first study, for schools, was used to estimate the health benefits for the residential sector. The study
indicates 20-year net present value (NPV) savings of $ 8 per square foot for reducing asthma and
colds/flu. A conservative 10% proration of this benchmark, multiplied by an estimated 35 square feet
per child (in a school setting), was used to calculate a dollar-per-person value that could be applied to
the prototype home. This approach yields a 20-year NPV benefit of $28 per person, $ 112 per home, for
health cost savings.
The second study, which indicates 20-year NPV productivity benefits of $37 to $55 per square foot for
LEED-certified buildings, was used to value increased productivity in commercial buildings. Because
the proposed green amendments are not as extensive as LEED requirements, a conservative 10%
proration to the average of the study findings, or $4.61 per square foot, was used. This rate per square
foot was then multiplied by the prototype commercial building size to estimate a 20-year NPV of $6,900
per building for productivity gains.
3. Economic Health
The economic health benefits of the code amendments were based on information provided by the
City' s Economic Advisor, Josh Birks, relative to a model used to assess the Mason Corridor. This
information included multipliers for direct, indirect and induced benefits. Direct benefits represent the
actual amount spent or invested. Indirect benefits (incremental) are defined in this model as increases in
economic health, by local suppliers, necessary to support local impact. Induced benefits are defined as
impacts on all local industries from wages derived from both direct and indirect impacts. The total
multiplier for all three benefits is 1 . 5 , based on 1 .0 for direct and 0 . 5 for indirect and induced.
2
ATTACHMENT 3
To ensure a conservative approach, only multipliers for indirect and induced benefits were used to value
the local economic benefits of the incremental cost to implement the proposed amendments for new
buildings (both commercial and residential). The result is an economic benefit of $2,000 per home and
$31 ,000 per commercial building. These benefits are considered one-time occurrences.
4. Carbon Reduction
Projected utility savings (electricity and natural gas) were used to calculate carbon dioxide equivalent
(COze) emissions reductions for both residential and commercial buildings. Point Carbon' s report,
Carbon 2010 Return of the Sovereign, March 2010, indicates an expected carbon price of $ 10 to $20 per
metric ton if trading is instituted in the United States. The Stern Review of the Economics of Climate
Change, March 2007, estimates the social cost of carbon to be $85 per metric ton.
Based on these two reports, $20 per ton, or the high end of the range in the Point Carbon approach, was
used to assign value to the carbon reduction benefit of utility savings. The annual value was then
converted to a 20-year NPV.

RE : Work Session Summary — December 14, 2010
Update on Green Building Program and Proposed Building Code Green
Amendments
On December 14, 2010, City Council held a Work Session regarding an update on the
development of the Green Building Program and proposed building code green amendments. All
Council members were present. Staff members making presentations and answering questions
were Utilities staff Brian Janonis, John Phelan, Doug Swartz, Gary Schroeder, and Felix Lee;
Community Development and Neighborhood Services (CDNS) staff members Steve Dush and
Mike Gebo ; and, Deputy City Manager Diane Jones.
There was extensive discussion and many clarification questions regarding the information
presented. Each Councilmember provided their individual perspective and feedback. Council
was generally supportive of the objectives of green building, and a majority supported moving
ahead with the approach proposed by staff as specified below:
• Residential and Commercial amendment packages. A majority of Council supported the
proposed packages of building code green amendments and requested staff provide a more
detailed benefit and cost analysis.
• Options. Several Council members requested that the four green amendment options be further
developed , including detailed costs and benefits for each option. Several Council members also
requested staff to consider voluntary, incentive-based approaches as well as regulatory approaches
for implementing the options.
• Timeline. Council supports a March 2011 adoption date for building code green amendments and
a January 2012 implementation date for most provisions.
• Electrically heated building requirements. Council members requested staff to prepare the
proposed specifications for electrically heated buildings as soon as feasible.

Fort Collins
• Implementation resources. Council has already approved funding to support additional staffing
resources in the Building Division to administer and enforce the proposed building code green
amendments.
• Green Building Program. Council encouraged staff to move ahead with developing voluntary
elements of an integrated Green Building Program to accelerate green building in Fort Collins.
Next Steps
• Develop building code green amendment ordinance language for the proposed residential and
commercial packages for City Council adoption on March 1 and March 22, 2011 .
• Deliver to Council a more detailed benefits and costs analysis for the building code green
amendments including a review/analysis of potential impacts .
• Deliver to Council information regarding development trends in Fort Collins, our region and
nationally.
• Develop and deliver to Council a clearer description of the four green amendment options,
including benefits and costs.
• Provide a list of green building amendment provisions that were considered by staff and the
technical review committees but were not included in the recommended packages.
• Review proposed ordinance with appropriate City boards and commissions, seeking their
recommendations for adoption, in January and February 2011 .
• Continue Green Building Program development, including building code green amendment

Although overall permit issuance has remained quite high , the types and values of permits have changed
significantly. 2010 Fort Collins permit valuation was 51 % below 2005 , resulting in significantly less
revenues .
Other Northern Colorado jurisdictions , for the most part, followed the same pattern as Fort Collins , with
numbers declining from 2005 until modest increases were realized in 2009 and 2010 . Fort Collins fell in
the top two jurisdictions for total permits issued for all six years , and led in numbers two of the six years .

National Trends
On a national basis , residential construction has followed the same trends . According to the Census
Bureau , during 2009 , 433 , 600 single family homes were started in the U . S . This compares to 1 . 75 million
new homes starts in 2005 . New housing starts are not yet available for 2010 .
As of April 2010 , the Mortgage Bankers Association forecast new single-family housing starts to total
556 , 000 for 2010 , 790 , 000 in 2011 and 1 , 058 , 000 in 2012 .
According to the Congressional Budget Office , the number of housing starts over the next few years will
depend on three factors :
1 . The underlying demand for new housing units ;
2 . Cyclical and financial conditions such as unemployment rates and lending standards ; and
3 . The number of excess vacant units that are available .
Commercial construction has seen severe reductions in retail centers and malls but relatively strong
growth in hotel/motels , higher education , health care and office facilities . The slowing economy has had
an impact. According to the Census Bureau , non-residential construction valuation reached $357 billion
in 2007 and $410 billion in 2008 . The adjusted number for 2010 had dropped to $302 . 7 billion .
It is anticipated that over the long term , there will be continuing demand from the health care sector for
new or remodeled properties as the percentage of Americans over age 65 continues to grow, increasing
demand for medical care .

The Business Case for Green Building
Source : U. S . Green Building Council web site,
www.us bg c.or isplUPage. aspx?CMSPaaeID=2331
1 . COMPETITIVE DIFFERENTIATOR
Green buildings with lower operating costs and better indoor environmental quality are more
attractive to a growing group of corporate, public and individual buyers. Green features will
increasingly enter into tenants' decisions about leasing space and into buyers' decisions about
purchasing properties and homes.
2. MITIGATE RISK
Green building certification can provide some measure of protection against future lawsuits through
third-party verification of measures installed to protect indoor air quality, beyond just meeting code-
required minimums. Faster permitting or special permit assistance can also be considered a type of
risk mitigation. Another risk management benefit of green buildings in the private sector is the faster
sales and leasing of such buildings, compared to similar projects in the same town. Green buildings
tend to be easier to rent and sell, because educated tenants increasingly understand their benefits.
3. ATTRACT TENANTS
Today's savvier tenants understand and are looking for the benefits that green building spaces have to
offer. The new Class A office space is green; lease-up rates for green buildings typically range from
average to 20 percent above average.
4. COST EFFECTIVE
The cost per square foot for buildings seeking LEED certification falls into the existing range of
costs for buildings not seeking LEED certification. An upfront investment of 2% in green building
design, on average, results in life cycle savings of 20% of the total construction costs — more than ten
times the initial investment. Additionally, building sale prices for energy efficient buildings are as
much as 10% higher per square foot than conventional buildings.
5. INCREASE RENTAL RATES
A 2008 CoStar Group study, which found that green buildings outperform their non-green peer assets
in key areas such as occupancy, sale price and rental rates — sometimes by wide margins. According
to the study, LEED buildings command rent premiums of $ 11 .33 per square foot over their non-
LEED peers and have 4. 1 percent higher occupancy. Rental rates in Energy Star buildings represent a
$2.40 per square foot premium over comparable non-Energy Star buildings and have 3 . 6 percent
higher occupancy.

ATTACHMENT I
We are going to City Council for the first reading. This is an update on the refinements,
and to give you some costs that will interest you. We are asking for support of the
proposal from the Affordable Housing Advisory Board. Your recommendations will be
forwarded to the City Council. This program is intended to match with City goals . We
want to make decisions to build buildings and provide benefits to green design buildings
that are with us a long time. This is the Green Building framework to balance regulation
and voluntary measures that will move everything forward and gradually create a market
transformation. Due to a push from council we have been focusing on the code piece and
we are hopefully getting close to the voluntary part as well. Instead of proposing a new
code we are proposing to amend the existing code to make it greener. For the residential
side it is primarily the IRC . Last time we showed you specific details on the proposals.
This is a reminder of looking at amendments in terms of a systems approach trying to hit
all of the important bases . Most want a performance based approach, and a broader
approach to green as council directed. Since December we have been to council and they
gave us the green light on the same track. We have been defining the proposal with a
flushed benefit costs analysis . Felix has been spearheading the effort to translate it into
ordinance language.
The three refinements on the residential side are: Low VOC materials (cabinets
excluded), Certified tropical hardwood, and envelope requirements for electrically heated
buildings
Blonder: I didn't see anything about drywall. Since we had the Chinese issue with
drywall, I wondered how that is addressed.
Swartz: It is not addressed specifically because they felt it was an anomaly.
Blonder: It is phased out now, but it has been a big issue.
Swartz: We have exclude cabinets because of availability. We did not want to make it a
formidable barrier. We wanted to provide a lot of push on the bottom end with regulation
and pull on the top end with information. We had some options in December that we took
to council for a preliminary reaction. The only one going forward is the Certified from
some agency coming from a sustainable managed forest. We went for the one that was
the most critical eco system impact. Plus, these woods are not used typically in a low
level project.
This is a small step and similar to the previous one in that it will help get people talking
about certification and why we are concerned about upstream issues. We are pushing the
envelope requirements for insulation, electrical heat (resistance heat) and cost, not ground
force heat pumps . Electric resistance heat is a more expensive heat source.
Cost & benefits:
There are three scales that interrelate and have different cost components at each level.
This is just an overview. It has a lot of pieces to consider and it is not an exact science.
There are some assumptions and we used methodologies about how to put numbers

around this. We came at this from two directions. The component analysis (bottom up
cost and benefits) on new prototype buildings and a community scale analysis. We tried
to be conservative in the assumptions . Some things could be quantified, but others could
not. Others have ranges to use different builders. This is an overview of the numbers .
• Energy water carbon savings
• Benefits at multiple levels
• Near-term costs, recurring long-term benefits
• Initial cost increases: Residential 1 % to 2%
• Commercial 1 % to 4%
• No quick payback for owners
• Increased enforcement time + cost
• Total benefits exceed total costs.
Sollenberger: Have homes here or anywhere with new requirements been observed to
see if this works in practice or is it just theory?
Swartz: There are a lot of volunteer green building programs around the country that
incorporate a lot of the same concepts.
Sollenberger : I just wondered if this has this been tested, or has it been proven to do
what you say it will? I would hate to see something implemented that did not do what we
purport.
Swartz: I do not know of anything on the list that has not been used elsewhere for
several years.
Sollenberger : For example: a certain efficiency furnace has been tested to save energy
over other furnaces.
Swartz: A lot of this is coming from volunteer programs . These are modest steps to try to
codify based on City Council ' s direction. We are encouraging the market to go beyond
this on a volunteer basis.
Blonder: Is this coming from LEED or Energy Star?
Swartz: Some ideas are from national green building standards. We have listed several
sources. Some ideas are from Energy Star' s new version, which are addressing some
problems seen in housing here.
Blonder: The second class point increased the cost. Is that a cost of the City, or is that a
cost that will be passed on to the home builders?
Swartz: It can be either or both. In the short terms, 2011 - 12, the City is covering that
piece with the 2B tax revenue. The City Council has stated that starting in March, the
3 of 22
ATTACHMENT 11
enforcement part will be covered. The Building Department is in a position where it
needs to review costs and revenue as a whole.
Sollenberger: So, these changes raise the threshold on the existing code. Have you asked
the entry level builders what it will do to the product they are already building?
Swartz: We had some builders on our residential advisory committee, so we had that
feedback all the way through.
Sollenberger: Are they already complying with this?
Swartz: Journey did not stick with us on the committee due to time constraints, so we
have gotten very little feedback from them in the last six months . There will be some
increases that will vary by builder. Habitat is a leader and is doing some of this already.
Big picture:
These numbers represent one year of construction with both residential and commercial
together. It is the costs over one year and benefits over a 20 year period. $2 .2 Million in
benefits to $ 1 . 8 Million in costs after one year of construction. Residential + commercial,
quantified elements only.
Costs summary:
$ 1 . 8 Million most in initial costs, next enforcement + one time costs for materials and
training.
Benefits:
Utility savings over 20 years, Building Valuation (will have a higher value in the market
place), Health + Productivity (hard to find national numbers on this), Economic Health is
a reflection that when you spend more money on construction that will revolve in the
economy counted as conservative . 5 multiplier which is .25 value. The carbon reduction
is hypothetical because nobody is buying carbon right now. It is based on an expectation
of the near future.
Sollenberger: I have a concern. Your costs are nailed down but this is a lot of assuming
and to base our decision on this is a leap .
Blonder : I like that you are being conservative. I think the building valuation increase in
value is extremely conservative. I know many buyers want the green buildings.
Swartz: National suggested 1 % to 5 %. Code does not have the instant recognition like
LEED . Part of this is to provide that market place recognition. Mike, I agree there are
many assumptions and we tried to mark them and where they come from.
Sollenberger : The hard costs we know, but the hard benefit is the blue. The rest has
some softness .

ATTACHMENT 11
Swartz: Our goal was to present what we knew to decision makers and help them
understand what we think is the big picture.
Speaker Unknown : The problem is that we are used to looking at hard dollars and return
on investment.
Swartz: (Screen on acronyms on "Return on Green".) The decisions we make when we
decide to build green reflect on our health and quality of life. We tried to put numbers to
them.
Sollenberger : What is the ROI?
Swartz: We could calculate based on our numbers and we can give it to the public.
However, it would not be attractive if you just look at the cost benefits.
Sollenberger : I think it is something the public should know.
Byers : Would the cost per month be greater than the cash benefit?
Sollenberger : Yes, what are the costs up front? When do the increases in costs get
returned?
Lee: That depends on the financing time. The finance costs could be greater than the
benefits over 20 years.
Blonder : Wasn't the utilities cost inflation rate very conservative?
Swartz: We tried to nail it down, but then we took the center of those numbers.
Blonder: There is a lot to all of this . Some will be very expensive. It seems like your
numbers are really low.
Swartz: Some are refinements of what is already in the code. The costs side will be
highest in the first days of the code. After a couple of years it is less and infrastructure is
improved and costs come down. We are trying to reflect day one costs . In reality, after a
couple of year' s refinement it will be considerably lower.
Blonder: I appreciated Appendix 1 . It is well broken down. Do you think you will
exceed these numbers?
Swartz: No, we don't think so.
Sollenberger: Using high side puts it at $5600 which give it a 2-3 year payback plus
other benefits .
Byers : What have you found looking at other cities? Is it in code or is it voluntary?
5 of 22
ATTACHMENT 11
Swartz: Use is on the increase. Santa Fe, Longmont, Boulder, Albuquerque, (others
listed) has adopted varied green building codes. We have not looked at them in detail. We
have been honing in to our own codes .
Byers : Have you considered adopting a reward program for voluntary compliance
instead of a code?
Swartz: Council is looking at a combination of both. To move the market we want to
reward builders who go beyond this. Council said to look at pushing the bottom end
quicker. These are small steps . Not radical.
Blonder: Under# 4 in Appendix 1 is one of the highest dollar items on the list. Is that
included in the ROI?
Swartz: That is not included as said in the footnote. For example: The Campus Crest
development is very contentious. We keep hearing they are proposing electric heat, and
people are concerned. Recently the owners approached CSU and said we need to learn
about green building. They said they are beginning to understand that Fort Collins is
different. A design cheret was held about three weeks ago and we participated. There
were about 60 people there. The owners were very clear that they misread what they were
getting into. They will have to go back and redesign the project to meet the expectations
of this community and apply it to other projects they take around the country. Message is
that Fort Collins is recognized as a leader in this kind of change. This is one step along
that path. We will be looking at ways to significantly reward builders that go beyond the
basic code.
Swartz: Next steps : We are taking this to Boards and Commissions January and
February. The City Council reading is in March.
Byers : It is hard to see a proposal like this and not see a conflict with the Affordable
Housing community. How do we reconcile this increase in costs even though they are
good things? Can we exempt some affordable housing construction in town for some of
this?
Swartz: There is no easy answer. I have not seen sentiment to exempt affordable
housing. The feeling is that all need the benefits that come from this . Maybe we need to
look at more creative financing approaches that can help take this into account? We are
seeing some of the affordable housing builders are some of the leaders and already
implementing some of these codes.
Sollenberger: All of those items were covered with a grant. The CDBG and some
Housing Authority rehabs were grant covered. They are a leader when it is free money.
And those costs are not passed on to tenants.
Swartz: Challenge is reconciling the individual cost vs. the benefit to community.
6 of 22
ATTACHMENT I
Sollenberger: It is hard for us to find balance. The other problem is the tax that is not
presented as a tax and it will increase mortgage and annual payment. They did not get to
vote on this. I have a problem because the people are getting hurt and we can't vote on it.
I am not swayed by council ' s desires . They are out in three months. I do not want to ram
it through on their watch. We should have more time. It is hard for me to be supportive.
Blonder: Do you see this as a 1 -2% increase in rent for tenants?
Swartz: I think it would carry through the same way.
Sollenberger: One of the problems with gas forced air in units is they do not make units
for the down size in the apartments. If we did multi-family units, it would be a less
favorable picture.
Swartz: After the Council adopts the Green Building, we want to make sure the builders
have enough support for the transition. If adopted in March, it will be effective the next
January. We want to have enough time to figure out the details and train the building
industry and put into place a quality assurance plan beyond the classroom training.
Next Steps:
• Alternative compliance path details
• Certification requirements
• Performance testing protocols
• Compliance forms, templates
• Fact sheets, field guides
• Staff + contractor training
• QA/mentoring plans
Blonder: I think the city should participate more in the costs of the project.
Waido: Currently the Affordable Housing Fund is to help compensate for the increase in
costs. They could put more money into the fund to help people buy houses. If you
increase the cost of housing, you immediately wipe out a segment of population from
getting into home ownership. They might not be there long enough to recover the costs.
Sollenberger: We are not suggesting that the owner will be there 33 years. Just that
someone will be there the life cycle of the structure (33 years), then it is the first owner
who is standing that cost increase.
Byers : I like the idea to increase the Affordable Housing fund.
Sollenberger : Yes, it needs to be done if you are going to mandate people to do this.
Qualified affordable is definable. Can we exempt out or something? The nonprofits are
eligible for all of that stuff. A private builder is not.
7 of 22
ATTACHMENT 11
Waido : There is an increase in costs, yet one of the benefits is that there will be a market
demand in the future. What if a qualified low-income buyer had that house discounted
and didn 't have to pay into that, would they pay for the increase in costs?
Sollenberger : The builder can bank that. It is no different than our down payment
assistance. That gets repaid.
Waido : This adds 1 % to cost of housing. On a $200,000 house that is $2000. Low
income pays $ 198 ,000 and not the $200,000 until they sell at an appreciated $206,000 for
example. Just a question. I don't have the answer.
Swartz: Regulation: In 201 lwe will have pre-implementation with refinements to City
Council. It will be implemented in January with Quality Assurance in 2012 . There will be
Amendments down the line. Some ideas are water metering for units vs. the building, and
land use code amendments ideas that were handed off to the Planning Department. Next
land use code update with Plan Fort Collins would consider some of these things .
Waido: Some examples could be like lot size and orientation.
Swartz: In review last year we decided to work on greening our code because regulations
are already supporting these concepts . Even though a lot of this is new in other places,
much of it is not new in Fort Collins. So the idea was to review and see where the
opportunities lay and take steps in other areas.
Incentives, Recognition, Education + training, regulation, costs + benefits are all above
code.
Please vote on this. Proposed Motion: The affordable housing board recommends the
proposed building code green amendments for residential and commercial
construction be adopted by council.
Sollenberger: How else does it affect the buyer? (Quick math on sample costs.) Possibly
a $ 17-34 difference in a monthly bill.
Byers : What we are talking about is $204 or $ 12/month at 6% . Utility savings is
$65/year. It will look at costs at the low end $ 165/year. That is a fairly small number.
(Discussion around the increase costs to renters or low income home buyers .)
Blonder : Worse for tenants than owners.
Byers : Rent is based on income. If it is city subsidized, the renter would not have to bear
the costs.
Blonder: I am more worried about the renters.
Waido: There is a city subsidy in town. City paid 10% at Province Town from CDBG.

ATTACHMENT 11
Sollenberger: Tax payers are not shelling out for that, it is HUD money.
Robinson: I like the idea of green, and that is where we need to go, but I don't want to
see a family not get a home because of this extra expense. I would at least want to see a
back-up plan for them, like a waive. At least propose this feedback to Council even if
they are already going to pass it.
Sollenberger: This is a more altruistic thought process, that we should do it for the
benefit of the people even if some can' t afford it.
Blonder: It is an image thing as well.
Sollenberger: Are we looking for a decision tonight?
Lee: It would be good to have something to put in the Council packets before March 1 .
Blonder : Let' s draft it and send it out by email.
Byers : Can we ask for a potential increase in the Affordable Housing funds .
Waido: We have rarely done any rental assistance, but no mortgage assistance program.
We could use homebuyer assistance to help buy down the interest rate or increased costs.
Many 1 " time buyers are only buying condos and townhomes. They can't afford a house.
Sollenberger : We are really only talking about the impact on the rentals .
Byers : The builders can 't pass the costs on to affordable housing renters because their
rent is based on income and they are maxed out.
(Discussion about construction of rental apartments and the justification of building.)
Sollenberger: Market rents just don't work in Affordable Housing. Rents have to be
above 1 .25/sq. ft. Does it make any difference? No one is building single family homes
that qualify for affordable. We are looking at apartment buildings only. I would like to
recommend it.
Byers : Council needs to know that this could have an effect on Affordable Housing in
Fort Collins .
Blonder: It is such a small amount. I agree with Mike and I agree with most of this.
Byers : I think it needs to be voluntary only.
Sollenberger : I agree.

Robinson : I would like to think it will make Fort Collins more attractive and bring in
more jobs .
(Short discussion.)
Byers : We should write a memo to support it, but these are our concerns and thoughts.
Sollenberger: Let' s mull it over and get feedback to Ben by February 11 ?
Members agree to draft a recommendation and present it by February 11 , 2011 .
Plan Fort Collins Update :
Presenter Ken Waido :
The next steps : Plan adoption is Feb 15 . The paperwork is to go to the council and staff is
presenting the updates to City Plan, Transportation Master Plan, and Pedestrian Plan for
adoption. Some land use code implementation items will be on March 1 first readings,
March 22 second readings. Regarding the ordinances, we talked about the changes to the
L and M zone. The density ranged is being changed at both ends. There are some changes
in terms of housing mix % requirements and what qualifies as a housing mix. Different
lot sizes. (2000 sq ft difference, above 5000 and below 5000 .) Can't do it in a single
housing type. Only with 3 housing types or more. The part of what has been up to this
point is being carried forward is the change in density in urban estate zone. P&Z meeting
county people were totally against it. Board will not recommend to the council. This is an
optional thing. The board has had a lot of comments sent previously. Do you want to
make a recommendation or just say something as comments?
Sollenberger: I don' t think it affects us from product type. We would assist with projects
that are small.
Waido : The Affordable Housing strategic plan is affecting us the most.
Robinson : Was the plan updated last year?
Waido : Yes, in July.
Blonder : Does anyone want to make a recommendation? Maybe Ken and I can meet on
this .
Waido : I am 70% devoted to Affordable Housing. My time is totally consumed by Plan
Fort Collins and will be until the end of March. Then I will be able to pick up some more
Affordable Housing projects. I want to look at the 6-month planning calendar. Some
months are blank and I am asking you what else you want to put on this such as
discussion interviews. The incentives is a good one.
10 of 22
ATTACHMENT 11
Sollenberger: Have a member of the attorney staff explain why they think the Housing
Authority has to have a controlling interest before they give a tax credit. That will shut
down the Housing Authority participating in tax credit deals .
Waido: The June Meeting is schedule for June 2 and I will need to be out of the office.
We might have to look at rescheduling to another date. Ben won't be here for August
meeting.
C. Other Business
Waido : Donna Murton is changing her Union Place project. It will be a senior rental
project. I think it will be 50-60 units but I have not seen the final numbers .
Sollenberger: If a manufactured product has a HUD stamp can it ignore local code? That
has a lower standard on everything than FTC has .
Lee: I do not know.

Monthly Financial Report
(Presentation available upon request)
Utilities Financial Operations Manager Ellen Switzer presented the Monthly Financial
Report. Ms. Switzer noted the information has not been audited yet. , and purchase
power expense increased 8 . 7 percent above 2009 . Figures exclude depreciation and
grants.
Operating revenues represent revenue from meter reading activity.

ATTACHMENT 11
Key Financial Results:
How does the Southwest Annexation cost match up with the amount budgeted_ _ _ . would
like to see this information included each month. Part of the -4. 8 percent variance for
capital additions relates to less cable replacement than anticipated, as well as managing
projects low and delaying.
Is it an issue for the Utility to not spend capital money? We have identified revenue and
expenditures, which should balance. We 've been budgeting a loss in the last few years to
draw down reserves.
Two types of capital budgets: lapsing (those funds if not used in the year, they are not
available to spend the next year, but do go into reserves); non-lapsing (the funds stay with
the life of the project).
Energy and Demand by Month:
Planning Engineering Manager Bob Micek uses this information to report to Platte River
Power Authority. It was suggested to normalize the annual peak demand by reflecting
average temperature; interest in seeing how much it fluctuates over time.
Operating Revenue:
In 2010, operating revenue increased 11 percent from 2009 due to a 7 .4 percent rate
increase and increased kWh sales in the residential class.
Non-Operating Revenue:
Sale of equipment and parts, repair of damaged equipment; interest income.
How are grant revenues tracked? Only available for the grant projects, so it is tracked
with the project but not in the budget.
Capital Projects (non-lapsing budgets) :
Total project cost compared to budget.
2010 Total Revenue Compared to Expense :
Purchase power represents 70-80 percent of our total expenses. Would like to see the top
three items that account for the reason why we came in under budget.
2010 Summary:
Additional appropriations approved by Council are required if we need to spend over our
budget. Contingency funds for unexpected events are placed in one line item of the
budget for ease in keeping track of where they are. Philosophy of not spending just
because we have the budget.
Ms . Switzer thanked board members for their suggestions and will make those changes .

Building Code Green Amendments
(Presentation available upon request)
Green Building Code Project Manager Felix Lee and Energy Services Manager John
Phelan presented this topic to the Board. Council directed staff to develop mandatory
building code green amendments to be integrated into the City' s existing building codes
for residential and commercial construction. Council will consider the proposed "green"
amendments to the Fort Collins building code at their March 1 and March 22 meetings.
The purpose of the Green Building Program is to align . . . . (from presentation slide).
The substance of the proposed amendments remains the same since staff provided an
update to the Board at the December 1 , 2010, meeting. Refinements to the proposal since
that time include:
- Low-VOC materials : cabinets excluded
- Daylighting deleted
- Occupancy control of lighting in defined spaces
- Certified tropical hardwood
- Special provisions for electrically heated buildings (increase envelope insulation
requirements)
The Board received a comprehensive benefits and cost summary. The benefit-to-cost
ratio represented as one year of construction, residential and commercial, quantified
elements only with a 0 percent inflation rate, costs total $ 1 .76 million, and benefits total
$2 .23 million. Benefits include carbon reduction, utility savings, building valuation,
health and productivity, and economic impact on the community. Mr. Phelan explained
the concept of economic multipliers .
Staff will round to boards and commissions through February. More information can be
obtained by visiting www. fcgov.com/gbp .
Was there consideration at making these voluntary rather than codifying them ? There
was a lot of discussion around this. Staff proceeded to develop those things that make
sense to codify and represent minimum standards.
Some of the example codes staff was comparing to revolutionary or evolutionary? Mr.
Lee, as a code official, was initially supportive of the two sets of standards in the
marketplace until he closely examined them. This change is evolutionary.
Did the City and stakeholders examine whether this would prevent developers from
coming to Fort Collins ? Staff discussed this factor and determined this is not a big
driver, compared to other costs such as infrastructure, etc. This is not viewed to be a
strike against new business .
Upgrade to Foothills Fashion Mall? If an addition was added or changing out major
systems, it may come under some of these code changes, but when the footprint does not
change, it normally wouldn't.
14 of 22
ATTACHMENT I
Six to twelve month lead times and bureaucracy in Fort Collins would be prohibitive
when developers can go elsewhere and build much quicker. Mr. Phelan noted planners
would counter that people want to live and develop here for the very reason of our high
standards. Energy Services and Development Review are both investing in time with our
community contractors to teach them how to get through the planning and permitting
processes. Fees from developers to Development Review will help support this program.
Concern that adding these products puts a home with these upgrades out of a lot of
people 's reach. It was noted one of the only remaining entry level residential builders in
the community would see no cost increase from these amendments; they are already
incorporating these measures in their products .
What was the stakeholders ' biggest issues ? It varied between the residential to
commercial groups. "Greening our code" in comparison to adopting a green building
model code was the biggest challenge for the residential group. The commercial group
was concerned about the practicality of enforcing these changes and implementing the
program.
Motion: Board Member Graham moved that the Electric Board recommends the
proposed building code green amendments for residential and commercial
construction to be integrated into the City' s existing building codes. Vice
Chairperson DeCourcey seconded the motion.
Vote on the motion: 5 for; 1 against.
Reason for nay vote : Board Member Barnish voted against out of concern that it will cost
the community too much (see other concerns above).
Board Member Graham recognized the effort put in by staff to develop this.

A motion was made to approve the November 18, 2010 minutes as written. The motion was
seconded.
3 . Green Building Program Update
The presenter stated they would provide information on work that has been accomplished on the
ordinance language and the benefit cost analysis. The green building team will meet with the
17 of 22
ATTACHMENT 11
Building Review Board again on February 24 h to review the ordinance language. They will be
looking for board input at that time.
The presenter reviewed the green building program goals which are to align with the city policies
of reduced carbon emissions, reduced energy and water use, to create better buildings, to avoid
lost opportunities and to continue our leadership role in Fort Collins. The green building code
amendments are a component of the larger green building program. As the code development
work is completed, the City will move to more market based recognition and incentive type
programs.
The amendments can be clustered into different categories, but the City is focusing on a system
approach. The presenter discussed changes that have taken place since the last presentation to the
Board. Cabinets have been removed from the low VOC proposal. The commercial and multi-
family list no longer contains a day lighting measure, and there is an additional measure for
occupancy control for specific spaces — mostly corridors and stairwells. Also, lighting in those
areas will be reduced to 50% when those areas are unoccupied.
The presenter stated that four options were previously being considered. Three of those options
have been removed. The remaining option is certified tropical hardwoods. The proposal for
higher electric heat building requirements would be implemented before January 1 , 2012.
The presenter also discussed changes that will be made to the 2009 I-Codes. Amendments have
been made to the ICR which governs single family homes and duplexes. Residential three-plex to
multi-family three story structures are covered under Chapter 4 of the IECC, and Chapter 5 of the
IECC covers multi-family buildings that are greater than three stories. Amendments have been
made to those two chapters of the IECC.
The presenter referenced benefit cost categories in Figure 1 . The green building team looked at
things from an individual perspective, from the building sector perspective, and the community or
the ecosystem. He added that the cost analysis is an inexact science. There are many moving
parts, and also many limitations on staff s time and resources. Staff has done the best they can,
but there is some variability.
A component analysis and a community scale analysis were completed. The component analysis
looked at each specific proposal and analyzed it. There are some studies and different pieces of
information to look at on the community scale analysis. There are both quantified and
nonquantified costs and benefits. Some are straight forward and easy to quantify. Some are
difficult to quantify; i.e. , benefits of a dark night sky from dark sky pictures. The results were
presented in ranges, recognizing that different builders would have different levels of experience
and different access to resources. The same is true with benefits. There are a lot of moving parts,
different size buildings, different configurations, so there is no single number.
They used prototype buildings for new residential and commercial construction to give grounding
to the numbers. The costs for the most part are near term costs, and the benefits are recurring
long-term benefits.
The presenter also discussed cost increases. They range from 1 % to 2% on the residential side
and from 1 % to 4% on the commercial side. There is no quick direct payback to owners, and
there will be increased enforcement time and costs. Overall analysis shows that total benefits do
exceed the costs, and the total benefit cost ratio is 1 . 3 . This is based on the analysis of one year
18 of 22
ATTACHMENT 11
of construction. There are some enforcement costs and then some training and support materials.
The training and support materials are really a one time cost, so they are a little different.
Regarding benefits, utility savings are about a quarter of the benefits, followed by building
valuation which is another big piece of the pie. Economic health, carbon reduction, and health
and productivity fill in the smaller wedges.
City Council will have the first reading of the ordinance on March lst. The second reading will
be March 22nd. Activities to be completed in 2011 include testing protocols and forms, templates,
fact sheets, training for staff and contractors and setting up a quality assurance program to use
when the program is implemented. The amendments will be implemented in 2012 . There may
also be a few instances where the ordinance needs further revision. Those tweaks could be
accomplished late in 2011 .
Once that is completed, staff will address the market driven aspects of the program with
recognition incentives, education, and training. There is a lot of information on the website that
addresses green building practice summaries, benefit cost analysis, and minutes from the track
meetings.
Chair Cram asked if any of the audience participants wished to speak
Axel Severts stated that he works for W.J. Bradley in Fort Collins. He is a lender. Mr. Severts
stated that his biggest concern is that the cost of new buildings will increase with the green
building program. In order for a remodeled house to get appraised with the added costs, there
would need to be similar green houses in the exact same neighborhood in order for FANNIE and
FREDDIE to accept the value. FANNIE and FREDDIE would actually have to change their
guidelines in order for lenders to add a line on the appraisal form to adjust it for a house that' s
green. Mr. Severts stated that his biggest concern is how homeowners would ever get an
appraisal to account for the green build remodels. In a new subdivision that is entirely green, the
appraiser could simply use the house next door.
Mr. Severts stated that he felt first time home buyers would be priced out of those neighborhoods
because they are the most sensitive about price. They are struggling to get into that first home
regardless of whether it is or is not green. There currently is discussion about FANNIE and
FREDDIE trying to get the green guidelines into their product mix, but there is also talk about
them going away. Every investor in the country underwrites to their guidelines. If it goes
private, how would green built ever get added to the appraisal form?
Board members addressed questions to the presenters.
A Board member commented that he has found a number of inconsistencies in the cost analysis
figures. A range of 1 % to 4% has been discussed, but 1 % to 2% is referenced for residential land
and up to 7% for commercial. So, 1 % to 4% doesn't jive with anything else in the rest of the
document. Another example is the initial costs in Appendix 1 . One percent of $250,000 is
$2,500, but the calculation is $2,835 . If staff is using 1 % as the low figure, then the rest of the
tables should match that concept. The presenter suggested that perhaps they could review those
specific areas with the Board member.
A Board member asked if anyone from the Board of Realtors and the real estate community has
been contacted for their comments and concerns. A presenter responded they have been
represented on the green building program advisory committee and some members from the real
19 of 22
ATTACHMENT 11
estate community have been on both the residential and commercial tracks. Staff realizes what a
challenge the underwriting will be.
A Board member questioned the cost impacts, ranges, and utility savings that were arrived at
based on the prototypes. He stated that the ranges are based on an entry level home in Fort
Collins, but the code will impact everyone across the range for construction. An example would
be that in a home that sells for $200,000 to $250,000, vinyl windows would be used for the
basement as well as the upper levels of the house. But in a $ 1 million home that uses Andersen
Windows, that impact could be significant. He would want to ensure that everyone knows the
project costs are based on a $200,000 to $250,000 home.
The Board member also discussed construction waste recycling. The low is zero and the high is
200. He asked if the Brendle Group or staff is assembling the numbers. A presenter responded
that they are most concerned about the cost impact to the entry level buyer. They did think that if
they put costs in percentage terms, even for a more expensive home, they would probably not see
a huge different range of percentages. They were clear in the report about the prototype that was
used, and the numbers for more expensive homes can be scaled up. They talked with builders,
contractors, subcontractors and service providers. They attempted to bracket the range in a
reasonable value that they were confident about. On construction waste recycling, the reason the
low is zero is because some services will be paid for related to recycling construction waste. Less
material will also be sent to the landfill. They are aware of some projects that have actually saved
money by implementing construction waste recycling. They also did not attempt to quantify the
existing construction, the remodels, and the additions because there were just too many different
combinations.
The Board member also asked about those alterations that don't require a building permit. In
those instances, the City will not know if the home owner installed a water efficient fixture.
Hovland stated that the intent has always been that the green code is applied to new construction
and then alterations with a permitted alteration. The City will never see a nonpermitted item.
The Board member stated that the philosophy behind the code program is to help conserve
electricity, conserve water, and reduce carbon emissions. Why wouldn't it also be mandatory for
all citizens in Fort Collins regardless of the work that' s being done? He stated he did not
understand why staff is looking at only one portion of it. A presenter responded that it is a
practical cut-off point. He added that the green building codes go above the baseline codes of
life, health and safety. The Board member disagreed, saying that the definition needs to be
changed because the new code is mandating that these changes occur on new construction;
therefore, the new code is the minimum standard for life, health, and safety.
A presenter added that the intent of the green building program is market transformation. It is a
bit of the 80/20 rule. We are getting the lions share of the savings for most buildings. Overall the
market is changing and water efficient fixtures will be the fixtures that are available at Home
Depot two years from now. It is going to be difficult for the consumer to purchase a toilet that
isn't 1 .28 gallons per flush.
A member asked if the additional interest that will be paid over 30 years on the increased loan
amount was considered in the calculations for the cost of those items or if it was just calculated
on the basis of how much more an item will cost. A presenter responded that the interest piece is
shown in the mortgage payment. It is best summarized at the bottom of the page on Appendix 1 .
A member also asked if the record-keeping and bookkeeping costs to the contractor have been
calculated. A presenter said they haven't explicitly quantified that, but they do reflect the
20 of 22
ATTACHMENT 11
contractor margin in the estimated costs so they are accounting for some of that burden. The goal
behind the code changes is not to increase burden. Staff is very interested in working with the
building community to try to make this as easy as possible. The goal is better buildings, not more
paperwork.
A Board member asked what percentage of costs for administration will be for the building
department. A presenter referenced Appendix 3 and stated there will be a substantial increase in
staff time. The funds for the additional staff have been appropriated by City Council so it is
available should they adopt the amendment. The Board member asked if the presenter was
comfortable with those numbers. The presenter responded that they felt the numbers were
conservatively high. The 45% falls within the national average for this program. There have
been some recent discussions that it may not have been enough. He added that these costs as well
as the initial costs will probably come down as staff becomes more experienced. Staff is trying to
represent in the cost estimate what' s going to happen in the near term. Based on passed
experience, watching other code changes, we will find this easier and less expensive than it seems
looking at it in the future.
The Chair thanked the Green Building Team for presenting today. He stated they are making
headway in producing a living viable document that works for everyone.
4. Election of Officers

6. Follow-Up Reports:
• A & J Construction — Coldiron reported that this was the gentlemen who was
struggling with the English language that was at a previous meeting with John Estabrook. The
board required that he frame a house within the City of Fort Collins. This has been done, and he
passed inspection. The City has finalized his full framer license at this point based on the Board' s
recommendation.
• February meeting — Coldiron announced that a luncheon is planned for the February
meeting. She offered to contact the City Manager' s office and invite Kelly Ohlson. Paul Eckman
will be invited to offer some coursework in board duties and responsibilities. Rick Reider will
21 of 22
ATTACHMENT 11
also be formally welcomed to the Board. A decision was made to start the meeting at noon. A
member suggested that lunch be kept simple and light to contain costs.
• Code Class — Coldiron stated the code class has been delayed so the green building
amendments could be included. She will schedule a room that will hold 200 to 250 people and
try to have it videotaped so it meets the ordinance requirements that the City has for contractors
who need to either take a class or take the amendments exam. That video could be available to
show quarterly to meet the needs of contractors.
7. Other Business
• Members provided Coldiron with new contact information.
• A Board member suggested that it would be helpful if it could be determined before
the Board meetings how many of the Board members will be attending. Coldiron stated that staff
would confirm attendance in the future.
• Coldiron reported that a new Building Development Review Tech has been hired.
Board member Schneider participated in 12 interviews with perspective applicants. Molly
Packard will be joining staff on February 22.
Meeting adjourned at 2 : 00 p.m.

Advisory Committee Member Comments
In the most recent meetings of the Technical Review Advisory Committee and Green
Building Program Advisory Committee meetings, members were asked to individually
comment about their sense of the proposed building code green amendment package.
Residential Technical Review Advisory Committee
♦ No items in particular seem like they would be a problem. It would be great to see
some order of what has the best payback.
♦ Concerned about a prescriptive code. Certified wood, DC blower motor,
commissioning and safe combustion are adding cost to the house.
♦ Cost is a big deal - especially in this economy. Whole-house ventilation is a big
concern because you are requiring a high efficiency, expensive fan because that is the
only way to meet energy requirements. Also, this negatively pressures the house and
essentially gets rid of heat recovery ventilation systems in Fort Collins.
♦ This is a good start. Not surprisingly, with such a diverse group of stakeholders, the
final package is predictably diluted.
♦ The proposal is on the right track.
♦ Agreed: this is on the right track. Electrical efficiency seems like it was left out of the
code proposal, though. Energy-efficient lighting package not addressed. Could
include requirements around daylighting and phantom load controls . These options
could be easy and low cost.
♦ The standards could be further increased beyond the proposal. Electric heat versus
gas heat requirements may push people to use a non-renewable energy source (gas) as
opposed to an electric system that could be powered by renewable energy.
♦ The code proposal is not too heavy-handed; it strikes a good balance. Makes
improvements but won't create a big push back. Convince the council that this is a
good place to start and then monitor it to make sure it is working and how it could be
improved.
♦ This is a good start. Electric heat homes are viable.
♦ From the enforcement side this is all very doable. This is going to increase cost on the
industry's part. Would like to have the building department verify compliance for the
new measures as opposed to requiring third-party verification.
1 of 5
ATTACHMENT 12
♦ This is a good start. It' s not as heavy-handed as it looked like it might be. Builders
may have some challenges document that materials are low-VOC or certified wood.
When do additions or remodels come in? Whole house ventilation should be
considered when looking at HVAC system design. It is not a simple, stand-alone
item.
♦ Concerns about the cost to the customer and impacts on affordable housing. For
someone who is just getting into the market, a big upfront cost may be too much and
drive them out of the community. Remodels need to be addressed. Cost and length of
inspections is a concern. This will be a lot of information for the inspectors.
♦ Recycling plan needs to have a template to provide consistency. Insulation
installation requirement could be a judgment call on behalf of the inspector.
Commissioning should be verified by the City. Low-VOC material list is going to be
difficult to verify and enforce.
♦ The proposal sets a good direction. Be sure to think through the implementation
details carefully so that it works. The builder has little control when it comes to
interior lighting/material selections.
♦ If City Council wants a prescriptive code then this is a good start. A points-based
system would encourage people to look at green building from a broader perspective.
We have spent a lot of time on new construction - how is this code going to affect
remodels and infill?
♦ Some sections may be more appropriate to incentivize instead of mandate. A points-
based system would foster creativity.
♦ The code is well balanced and hits a lot of different topics. Remodel aspect of the
code is huge. Training and education are important and should be considered for the
implementation plan. Will the low-VOC requirements really have that much of an
effect? Perhaps the code should focus on the material that off-gas for the longest
period of time.
♦ The code proposal should also include future items that staff would like to include in
the next version. This will allow the market to plan ahead and possibly change faster
than the next round of code adoptions.
♦ The timeline for this project seemed short at some points but it kept the group and
process focused. It would have been great to get builders in the room who are
building to lower standards. The amendments are a good start to pushing green
building in the building community.
♦ City Council should not have asked for a prescriptive code. It would have been better
to have a voluntary green building program. The enforcement of some of these
2 of 5
ATTACHMENT 12
amendments will add cost to both the City and builders. The City needs to be careful
about requiring too much documentation.
♦ It seems like increasing regulations causes a negative reaction from some developers.
Voluntary and educational programs can have a more positive impact on the
development community. Fortunately, the regulations that did come out of this
process do not seem like they are too onerous.
Commercial Technical Review Advisory Committee
♦ Some of the items are very important and some are becoming the building standard. It
would be interesting to do a prioritization exercise to identify key items from the
proposed code that should not be discarded. Incentives are important as well as
implementation and enforcement.
♦ This is the beginning of a cultural shift in the industry. Hate to carry a stick around to
make people do things but in today's economy it may be necessary. This is a good
place to start. The biggest potential in our community will be in the existing building
side of things . The requirement for energy assessments prior to alterations is a good
start. That will help building owners see where the improvements can be made.
♦ Construction waste management, building envelope, insulation are all important to
green building. Some good steps have been made but I still worry that this is not
enough to really catch us up but making us less behind. When this is presented to
Council, Staff should focus on other values to society not just capital investments.
♦ This is starting out at a good spot. It is taking a step in the right direction but not
adding too much burden to economy. Some more documentation of first costs and
savings is important.
♦ The City is headed in the right direction. Stakeholder process is important and staff
did a great job of including the community.
♦ We are up in front at looking at this type of code. This is a strong beginning to create
a green building code. Glad IGCC was thrown out and that staff was able to see how
the code could apply additions, remodels, etc. Also glad staff looked at local impacts
to builders . Didn't want the code to be too cumbersome.
♦ This is a fragile place in the economy. This proposal is a positive start. Education is
important. The market is going this direction. As long as builders know what to do
and have all of the available resources, this is a good start.
♦ This is a good common ground for items that have a lot of impact. Building envelope
is critical to the GB code. Many builders are uneducated about it and it is being done
wrong over and over again. Education is important for these items. Worried that the
3 of 5
ATTACHMENT 12
City is not going to fund the building department to implement this code. You should
not necessarily have to save money to do the right thing.
♦ Building envelope is huge. From an inspection standpoint, staff has been learning
how the systems integrate. It is going to take a lot of time and training to understand
how it all works. The process does work but sometimes it is a cultural change that
you can't really put a solid savings to. Integrated design is important.
♦ Don't want to be so far out that we get ourselves in trouble. This puts us in front but
not too far in front.
♦ Wish that there was more of a push. The challenges that we face as a society are so
big and the changes that we are proposing are so small. It is difficult to create change
in the current system because we need more radical change. This is a step in the right
direction but it is not big enough.
Green Building Program Advisory Committee
♦ Education and incentives are extremely important to the success of this program. The
costs to the City and building community should be seriously considered.
♦ The City' s energy policy goals will be very difficult to achieve without some of the
mandates that are outlined in the amendment proposal. This also supports other City
goals.
♦ Council is going to need more specific information before they can make a decision.
Overall, the amendment proposal is on the right track. Deconstruction should be
considered for the proposals.
♦ Staff has done a great job of summarizing everything. Some of these items will add
cost but they are on the lighter side of green building regulations. Integration is
important for these proposals. If builders look at each item as something that has to be
added it is going to cost more than if these practices are integrated into the design and
construction.
♦ The code proposals are a great compromise between people who want more and those
who want less. The TRACs worked hard to find items that would make a difference
but not push things too far. A market for green does exist in our community.
♦ Council needs to be careful about putting too much burden on the building
community. Existing homes need to be addressed in this code.
♦ A lot of gaps exist in the information that is available in the proposals and cost and
benefit information. These are all good measures, but more information is needed for
Council to make an informed decision.
4 of 5
ATTACHMENT 12
♦ The City could research how other existing programs, like ENERGY STAR New
Homes and National Green Building Standard, could be used in our community.
♦ From a realistic, practical standpoint from the residential sector, this code is pushing
things too far. The market is starting to move this way but a lot of people are not
ready to pay more for " green. "
♦ The adoption of this code should be delayed to give staff and the community more
time to understand the details and decide if it is the right move.
♦ The financial piece and how this code will impact the business community is a big
concern. Incentives are important to help move green building forward and address
the existing building stock in Fort Collins.
♦ City Council is looking for something that is more aggressive. The C-TRAC really
tried to find practices that could be implemented as soon as possible and have big
impacts. The IGCC would have been a huge burden on builders and owners . These
proposals are a great compromise. It should be up to City Staff and City Council to
decide when the code should be implemented.
