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. These Ordinances, adopted on First Reading by a vote of 5-2 (Nays: Kottwitz, Troxell) incorporate a
package of "green amendments" into the Fort Collins Building Code. The proposed amendments address
opportunities with regard to resource efficiency, energy efficiency,water efficiency, indoor and outdoor environmental
quality, and buildings operation and maintenance.
BACKGROUND / DISCUSSION
A numberof minorchanges have been made in the Ordinances considered on First Reading,based on ongoing review
by staff and are intended to consolidate and clarify areas of potential confusion. The key substantive changes are as
follows:
• Improve consistency between parallel Codes that address different types of buildings. For example, the
commissioning requirement for heating/ventilation/air conditioning systems included in the International
Residential Code(applicable to single-family detached homes, duplexes and townhouses)was added to the
International Mechanical Code(applicable to multifamily residential buildings)so there is internal consistency
across the different codes.
• Clarify applicability of particular amendments to existing buildings. In some instances the First Reading
language was unclear as to whether the proposed amendments were intended to apply in a limited manner
or not at all to building alterations or additions to existing buildings. The Ordinance language has been
modified to make this distinction clear, in a manner consistent with the description of the changes that had
been provided by staff.

Additional Information
In response to questions from Council during the First Reading of the proposed ordinances,staff is providing additional
information:
• Residential green building practices considered but not included in the proposed green amendments. A
complete list is included as Attachment 2.
• Funding for implementation support.The budget needs for development of support materials and training have
been roughly estimated at$100,000. These implementation support activities will primarily take place during
2011, prior to the proposed January 1, 2012 effective date for most of the amendments. Funds to cover this
are available through the Utilities 2011 Energy Services budget. Additional training will be offered in
subsequent years,funded through the Utilities Energy Services budget. Resource needs for ongoing training
are expected be significantly lower than in 2011.
• Funding for enforcement. The increased budget needs for enforcement of the proposed amendments have
been estimated at $158,000 annually for an additional staffing of 1.5 full-time-equivalent positions in the
Building Department. Council recently allocated funding from Keep Fort Collins Great revenues to cover this
increased need for 2011 and 2012 so building permit fees will not increase as a result of the green
amendments.
• Baseline data. A variety of data regarding Fort Collins design and construction practices were used to develop
the proposed green amendments. Data sources included the following:
o Technical Review Advisory Committee(TRAC)members. The residential and commercial TRAC included
numerous individuals active in building design,construction and code enforcement. Their experience with
current design and construction practices was part of discussions around the development of the green
amendments.
o New home performance surveys conducted in 1999 and 2007. These studies provided a wealth of data
regarding design,construction practices and performance for new residential projects in Fort Collins. The
first data set was published (www.fcgov.com/utilities/img/site_specific/uploads/newhome-eval.pdf); the
second has not been published; but the information it provides was frequently referenced during the green
amendment development process.
o Integrated Design Assistance Program projects. Utilities staff work closely with design teams for
commercial projects receiving incentives under this program. Discussion and modeling includes the
relationship between proposed designs, code requirements and current practice. Staff often has the
opportunity to monitor construction practices on these projects as well.
Baseline data is reflected in the "Current Practice" and "Context' sections of the Green Building Practice Summary
for each proposed amendment, available at www.fcgov.com/gbp.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinances on Second Reading.

EXECUTIVE SUMMARY U,
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 et positive-benefit fcompared�with buildings constructed to current Code
requirements. The changes in Code/requirements are projected to;mcreaserinitial design and construction costs by
1% to 2% for residential buildings and 1% to 4% for comrnerciaPbuildings' 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 effectivye 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 waterzuse. Green building has-a strong policy basis,with the 2008
NN
Climate Action Plan, 2009 Energy Policy and 2009 Water Conservation Plan:
The Utilities department is leading theme. ffoYrrt�of developing the Green Bui ing 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 comme�cialrsector. Members were invited to participate based on
their technical and market expertise.\Each cdmm\ttee 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.

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-g lance"-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 m 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((addresslplectrii •c—allyy heated buildings.
Effective date for electric Beat buildings amendments. Basedl on Council direction at the December 14,
2010 Work Session, the amende`d-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 instal omponent Aso they-delive,rated performance. This is what drives the
amendments regarding insulation installation standards andinstallation procedures forwindows,skylights and
doors, as well as plans for\training and developing-field guideslthat clearly illustrate important thermal
envelope details. Staff expects,to_recommend that tQ next steps inithermal envelope requirements betaken
Lf
with the 2012 I-Codes package c ru gently 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. ear-life with a 7%discount rate), would be about
r - — .�
$0.40 per kilowatt-hour, compared'to,the current Fort Collins Utilities' residential rate of about$0.08/kWh.
, I I .. k� ii i �� i
The same-sized system on the commercial prototype-would add•at out 1% to the cost of the building, while
meeting only about 3% of annu`�al lectrical needs. The$18,000 cost assumes no tax incentives or utility
rebates. � \a' , u
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 200ff 5 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 Codeslthat 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�vclu to ary'Green Building Program elements (education, .

or the Land Use Code. `� �✓
Implementation Planning LJ lJ
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

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-communit�/goals embodied in the Energy Policy
(2009), Water Conservation Plan (2009)'nnd the Clim toe Action Plan (2008), while providing a variety of
benefits for building owners�r 'nd occupants. �� ���
• Costs incurred at the individual, building�secttor)orlcommunity/ecosystem levels can produce benefits at
multiple levels. U
• 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,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 5%to 10%for residential projects and
20% to 30% for commercial projects.` �� �,—� R fJ

• Increases in Code enforc m 'n time are estimated 6L1n the order oU45% 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 Plan ing," will support a smooth transition to the new Code
requirements. Funds covering thesiyeeds-have bee n-appr�opriatedtin the Utilities 2011-2012 budget.

• Enforcement. The amendments will+representlincreasedi enforceiment staff time. This cost has been
accounted for in the benefit cost analysis Council'recently allocated funding from Amendment 26 revenues
to cover increased enforcement•staffing\,�,fo`20:11 and 2012. ThiL means that, in this time frame, building
permit fees will not increase as a result of-the 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.specifiic to-Fort-Collins or green building;they are national in scope
and part of the challenges buyers fac a when_tryi ng to secure,financing fov,home they wish to build or buy.
Efforts are underway at the state and national'1evel\o modify regulations toi ke 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/furthendecline.
Council members asked staff to prold(e information on development trends m Fort Collins, regionally and nationally
to help better understand these dynamics-Relevanfdata 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
N� u u
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 ro ected at,5%to�10%of annual emissions for residential construction and 17%
to 26% for commercial constpru tion" �( 11, ( UJ \U/
• Landfill diversion. The construction waste recycli`g-amendment will divert materials from the landfill.
Enhanced durability anticipatedto,result from,seve�al dmendments will reduce maintenance requirements and
associated waste disposal. Theebenefits 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).
