City of Fort Collins Building Performance Standards (BPS)
Our Climate Future (OCF) and BPS
Our local community helped shape the City Council-adopted OCF plan. The plan defines success through the
achievement of key outcomes, referred to as ‘Big Moves.’ Steps to achieve Big Moves are defined as ‘Next Moves’ or
strategies. A BPS policy is a Next Move that supports Big Move 6: Efficient, Emissions Free Buildings. Recommendations
were developed to address community and council priorities. BPS is the most impactful direct policy action the City can
take toward advancing Big Move 6.
Policy Impacts
City staff estimate the number of metric tons of carbon dioxide
equivalent (MTCO2e) avoided due to the proposed BPS policy will
go up each year, tapering after 2030, as shown to the right. The
estimate assumes larger buildings meet their targets by 2030, and
subsequent gains in avoided emissions would come from buildings
between 5,000-10,000 square feet.
Once final targets are met, BPS policy savings are projected to be
65,000 MTCO2e each year. By 2050, that equates to cumulative
savings of 1.5 million MTCO2e. If policy adoption is delayed, each
year the community would emit an estimated 10,000 of additional
MTCO2e. This would mean falling short of the OCF greenhouse
gas emission goal by about half a percent each year.
Administrative and Community Costs
Total program cost for BPS is estimated at $270 million,
including administrative and community costs. Accounting for
administrative costs described in the September 2024 City
Council Memo, program administration is projected to be
$20/MTCO2e avoided.
By 2050, the community would save $630 million in energy
costs (represented in the total area after 2038 in the graph).
The policy is expected to pay for itself by 2038. Also by 2050,
the projected benefit of BPS implementation is $2.80 in
energy savings for every $1 that the community spends on
policy compliance. Not including natural gas savings,
community cost is $105/MWH avoided through increased
efficiency, compared to current community costs for electric rates of $118/MWH (projected to increase over time).
Economic Levers
Since 2002, Fort Collins Utilities has operated incentive-based
programs, and community consumption has decreased 24%. Despite
steady community growth, incentives have curbed the impact but
have not been able to lower overall electric use. Opportunity in
incentive-based programs is decreasing in the commercial space; in
2023, there was about half the participation in voluntary programs
compared to 2022. The City spent $2.5 million dollars in commercial
incentives in 2023, well below available budgeted incentive dollars.
Policy Development Process
Staff engaged the community for more than 18 months to shape the
proposed BPS policy. An industry Task Force, including representation from commercial real estate and local groups
(DDA, LLAC, North Fort Collins Business Association, and others), helped determine achievable policy parameters and a
structure that matches our community needs. A Technical Committee of local building science experts further reviewed
achievability of the structure and outlined specific Energy Use Intensity targets unique to building use types. Two external
vendors assisted with technical analysis. Significant additional engagement included environmental, business, community-
based groups, other jurisdictions, federal partners, and more.
A Focus on Feasibility
Staff centered engagement on determining what specifics could lead to a truly implementable policy with requirements that
buildings can achieve. This included establishing which buildings could and should be covered and how those buildings
could comply, with in-depth analysis and discussions of unusual case scenarios. This led to the development of several
safety nets tailored to accommodate unusual buildings that may struggle to meet targets. General targets were designed
with the short timeline in mind. Proposed final targets are what other jurisdictions consider ‘interim’ energy efficiency
targets, based on efficiency stemming from improvements to existing equipment rather than equipment upgrades.
Supporting Data
Benchmarking Data
Covered building owners provide annual benchmarking data per Article XI, §12-203 of City Code. Building owners report
details including their buildings’ property use type and use specifics, square footage, energy consumption, and more.
Reported data are filtered through 36 flags to determine if they are within normal parameters. Things like abnormal energy
use and drastic changes from previous years are flagged, along with specifics associated with various property use types
like unusual number of computers in offices or bedrooms in multi-family buildings. Buildings that trip a flag can only come
into compliance after speaking to a Help Center staff to explain or correct the abnormal value. About half of the 1,371
covered buildings have tripped flags since the start of the program in 2019. Every single flag has been addressed through
a conversation with the building owner or representative. Current program compliance is over 97%. BPS policy proposes
covering this same cohort of buildings.
Alternate Data Sources
Benchmarking data are considered a primary data source because they are entered by building owners or
representatives. Other data sources are compared to benchmarking data for validation and to provide robust supporting
data for BPS policy development. Reported electric use can be validated against Utilities meter data; reported use is the
more accurate metric in most cases given manual changes to appropriate meter aggregations. Property use type and size
is recorded by the Larimer County Assessor as well as reported by building owners when benchmarking. Reported data
are manually entered by building owners during benchmarking, including adding square footage of each property use type.
These metrics are further verified during benchmarking reporting through conversations with our Help Center. About 97%
of covered building representatives have communicated directly with our Help Center, allowing for verification of
unexpected reported data and error corrections. Adopted BPS policies in other jurisdictions often require third-party
verification of benchmarked data but Utilities staff are hopeful they can perform some of this based on existing data,
saving building owners administrative time and cost.
To create energy efficiency targets, Utilities worked with two external vendors to review energy data from thousands of
buildings around the country, including but not limited to the following sources:
• Utilities billing and metered data
• Efficiency Works Business program data
• Larimer County Assessor records
• City of Denver benchmarking data
• City of Boulder benchmarking data
• ComStock Analysis Tool (U.S. Department of Energy)
• Commercial Building Energy Consumption Survey (U.S.
Energy Information Administration)
• California Energy Data and Reporting System
Over 200 data fields were reviewed per building, and many data outliers were reviewed individually. Staff incorporated
local case studies to further ensure feasibility.
Cost Data
The basis for the local cost information was derived from publicly available cost assumption information, potential studies,
and contractor reporter total project costs (through the Efficiency Works Business program). The BPS Cost Benefit
Analysis considered costs for improvements and electric savings through 2035, without accounting for the increase in
rates that will be necessary to offset increased electric use if building efficiency is not advanced through this and other
efficiency-focused policies. Costs provided also did not include any ‘business as usual’ assumptions, but rather factored
100% of total project costs (e.g., including costs for equipment already at the end of useful life, upgrades that would
happen without policy adoption, etc.). Total costs per property before factoring in incentives, rebates, tax deductions, and
other financial assistance equal approximately 1% of each buildings’ last purchase price, also aligning with the average
cost of a tenant finish over the last 10 years ($200,000/building).

City Buildings
As established in 2022, buildings owned by the City of Fort Collins are currently required to
comply with performance standards (§ 12-203 (c) of the Municipal Code). The code states that
by 2026, City-owned buildings must define a standard percentage reduction to be meet by City-
owned buildings.
Building on the code’s impact, City staff collaborated with community experts to define
achievable recommendations for citywide Building Performance Standards (BPS) that can be
applied to commercial and multi-family buildings within Fort Collins.
The City strives to lead by example, and staff received strong support from City Council to alter
targets for City buildings to align with targets set for community buildings should City Council
adopt BPS requirements for privately-owned buildings.
A September 2024 memo submitted to City Council outlined specific requirements for City
buildings to come into compliance, including an analysis of overall costs for those buildings that
will need to take action to reach proposed BPS targets.
In addition to regular maintenance, efforts continue to improve City-owned buildings so they can
achieve proposed BPS targets and to advance Council’s electrification priority. The following
case studies demonstrate ongoing and recent efforts in three City buildings and the results of
those efforts, both expected0F1 and realized.
1 Program savings are based on the calculated difference in efficiency from existing to installed
equipment and are customized accounting for building use specifics (e.g., lighting savings factor
wattage differences between new and existing bulbs and actual hours of use). Calculated
savings may not align exactly with reductions in consumption due to the range of other variables
impacting electric use, however savings can accurately be viewed as usage that would exist
without upgrades.
Fossil Creek Park Shop, 5833 S. Lemay Ave. (FC2975)
The Fossil Creek Park Shop is a 6,550 square foot shop built in 2000. The building’s 2024
reported Energy Use Intensity (EUI) was 118.4 kBtu/sq ft, 34% over the proposed Fort Collins
BPS EUI target for the property use type (Other- Public Services) of 84 kBtu/sq ft. As part of the
proposed policy to Council in 2024, staff recommends building of this size not needing to
exceed a 15% reduction from its reported energy use. This “energy reduction cap” means that
this building will have a modified target by the 2035 timeline, and instead of the 84 kBTU / sq ft,
it will need to achieve an annual reported target of 100.6 kBtu / sq ft.
The building’s total electric use in 2022 was 87,360 kilowatt-hours (kWh), and in 2023 was
77,840 kWh. A lighting retrofit in 2023 had some impact on 2023 annual energy use and will
have more in 2024. The building’s 2025 reported EUI will therefore reflect the reduction in EUI.
Similarly, a roof top unit (RTU) retrofit and the installation of a building automation system were
completed in fall of 2024. Those will impact 2025 usage and appear in the building’s 2026
reported EUI.
The sum of savings below is estimated to be 36,943 kWh, accounting for approximately 38%
electric use reduction. The City also expects to see major reductions in gas use associated with
a heating, ventilation and cooling conversion.
2023 interior lighting retrofit
• Cost: $14,005
• Utility rebate: $11,194
• Total project cost after rebate: $2,811
• Simple payback: 3.8 years
• Annual estimated kWh savings: 9,403
2024 heat pump RTU retrofit
• Cost: $42,835
• No direct Utility rebates are available for HVAC rooftop units. HVAC rebates are provided
to distributors to provide access to high efficiency HVAC equipment
• Simple payback: 10.0 years
• Annual estimated kWh savings: 15,340
• RTU conversion to dual fuel heat pump technology (electrification)
2024 building automation system
• Cost: $49,500
• No direct Utility rebate available
• Simple payback: 12.0 years
• Annual estimated kWh savings: 12,200
Traffic Operations, 626 Linden St. (FC1313)
Traffic Operations building is a 9,500 square foot office building built in 2000 located at 626
Linden St. The building’s 2024 reported EUI was 73.9 kBtu/ sq ft.
As part of the proposed policy to Council in 2024, staff recommends building of this size not
needing to exceed a 15% reduction from its reported energy use. This “energy reduction cap”
means that the City Traffic Operations building will have a modified target to achieve by the
2035 timeline; and therefore instead of the 56 kBTU / sq ft target proposed for office buildings, it
will need to achieve a reported EUI of 62.8 kBTU/Sq ft.
The building’s electric use in 2022 was 109,560 kWh and in 2023 was 108,240 kWh. The RTU
and building automation system projects are scheduled to be completed Nov. 19, 2024. Those
will impact 2025 usage and will appear in the building’s 2026 reported EUI. Projects outlined
below and associated usage reductions will lower the building’s electric use by a projected 39%.
The City also expects to see major reductions in gas use associated with a heating, ventilation
and cooling conversion.
2024 heat pump RTU retrofit
• Cost: $557,836
• There is no direct Utility rebates available for HVAC rooftop units. HVAC rebates are
provided to distributors to provide access to high efficiency HVAC equipment.
• Simple payback: 10.0 years
• Annual estimated kWh savings: 27,060
• Eliminated one RTU by combining heating and cooling zones in the building
• RTU conversion to dual fuel heat pump technology (electrification)
2024 building automation system
• Cost: $81,200
• No rebate available
• Simple payback: 12.0 years
• Annual estimated kWh savings: 25,000
Building Services, 281 N. College Ave. (FC2660)
Building Services is a 37,603 square foot office building built in 1970.
The 2023 reported EUI was 63 kBTU/ sq ft. The building is required to meet the proposed BPS
office target of 56, or would need to reduce its overall energy use by approximately 11.7% to hit
the target.
Based on a desktop audit, opportunities were isolated for reductions from lighting upgrades and
HVAC controls. Costs were estimated at $107,145 before rebates, or $2.85/square foot. The
desktop audit did not include opportunities from retrocommissioning, noting that City staff
ensure equipment is maintained and calibrated on a routine basis, and the heating and cooling
system is tested and balanced periodically.
After the case study, heating and cooling technicians performed semi-annual maintenance on
the existing RTUs, taking extra time to do more extensive cleaning of the coils and filters (which
build up with dust, dirt, and cottonwood seeds). Based solely on this effort, at no cost, the RTU
performance and energy performance improved to the degree that the building is now meeting
proposed EUI targets. As the City Assistant Energy Manager stated, “Clean coils and filters
equal improved energy and comfort performance.”
Community Buildings: Efficiency Works Business
Program Participants
Fort Collins Utilities has offered rebate programs to commercial customers for over 20 years,
accounting for about 60% of Utilities historic program savings1F2. Efficiency Works Business
(EWB) rebates and incentives accounted for 5,823 megawatt-hours (MWh) reduced electricity
use in 2023, down from 11,492 MWh in 2022. EWB has resulted in a total nearly 200,000 MWh
electricity saved since the program was initiated, which is more than 27,000 homes use each
year. A significant amount of EWB program participation has been in lighting upgrades, however
many properties benefit from several other rebates and incentives, from grocery, RTU controls,
envelope, variable frequency drives (VFDs), custom rebates on virtually any other upgrade that
save energy, and more.
In recent years, participation in incentive-based programs has waned; Utilities spent half the
money on commercial rebates and incentives in 2023 that were spent in 2022. This may reflect
reduced opportunity in high-impact, low-cost projects with engaged building representatives.
However, engaged building owners have significantly reduced their energy consumption via
participation in EWB offerings, reducing electric use up to 75% below pre-participation usage.
The following case studies represent a subset of local commercial buildings that have
participated in EWB program offerings multiple times over the last decade, including total out-of-
pocket costs, rebate amounts, and electricity saved. While these studies only reflect a small
fraction of the buildings that have engaged with EWB since program inception, these properties
demonstrate significant savings and a range of efficiency projects.
2 Program savings are based on the calculated difference in efficiency from existing to installed
equipment and are customized accounting for building use specifics. For example, lighting
savings factor wattage differences between new and existing bulbs and actual hours of use.
Calculated savings may not align exactly with reductions in consumption due to the range of
other variables impacting electric use, however savings can accurately be viewed as usage that
would exist without upgrades.
Foothills Unitarian Church, 1815 Yorktown Ave.
The Foothills Unitarian Church is a 29,612 square foot worship facility built in 1969. It also
includes the additions of an administration area in 1996 and a further expansion in 2022. The
building houses a preschool and a sanctuary with a kitchen, commons and administrative areas.
The church was estimated at just over 16,400 square foot before the 2022 expansion, which
added 13,160 square foot. For the expansion, the church partnered with Fort Collins’ Integrated
Design Assistance Program (IDAP).
According to a 2018 facility assessment, there are typically two to eight employees who occupy
the facility daily, however the facility can receive several hundred visitors during services and
other events. Generally, the facility is occupied to some extent six to eight hours per day. Utilities
provides electricity, water, wastewater and stormwater services.
Projects
In addition to several facility assessments, Foothills Unitarian Church completed five projects
rebated through EWB, an IDAP expansion project, and benefited from a Midstream Cooling
Program air conditioner. The building’s electric use went down 27% through lighting projects
(including interior lights, signs, classroom lights) and the installation of a high-efficiency air
conditioner.
Five lighting projects were completed since 2014 at a total installed cost of almost $19,800.
Rebates paid through EWB covered just below $13,000. Annual electric savings from these
projects total 35,400 kWh/year. Using 2024 commercial electric rates, that’s equivalent to
$3,330 in electric bill savings every year.
In 2023, Foothills Unitarian Church benefited from the EWB Midstream Cooling Program. EWB
works directly with regional distributors to make sure customers have access to affordable high-
efficiency air conditioning units. This program does not provide a rebate paid directly to the
customer, but rather directs funding to distributors to lower costs of efficient equipment. The
Midstream Cooling Program reduced the price of the air conditioning unit by $2,900 and
reduced electric use by 3,025 kWh per year over other comparably-priced units, saving an
additional $285 in annual electric bills.
Utilities’ IDAP provides technical assistance and financial incentives to help architects,
engineering professionals, and building owners optimize energy and demand savings and
reduce operating costs in eligible new construction and existing building major renovation
projects. Building owners receive a more integrated design process and overall, a more energy
efficient building. This happens through engaging the expertise of an energy consultant early in
the project to provide energy modeling services. Key program milestones, such as an early
design charrette (energy workshop) and energy modeling reports help keep energy efficiency
integrated in the design. An incentive of $12,015 was paid to Foothills Unitarian Church as a
part of their IDAP project, which focused on a 13,160 square foot project area and modeled
reduction in energy use of 183,703 kWh annually.
Current energy use
As a result of the efficiency-focused projects taken on by staff, the church reduced its electric
use by 27%. Their current EUI of 34.5 is below the proposed Fort Collins EUI target for worship
facilities of 35.
Fresh Foods, 1100 W. Mountain Ave.
Fresh Foods Market (previously Beaver ’s Market) is a 7,500 square foot grocery store built in
1942. At the time of the most recent EWB assessment, the building was noted to be cinder
block construction for the main space and wood frame for part of the back area. The building
has a flat roof with black membrane. General daily business hours are 8 a.m. to 8 p.m. with
slightly reduced hours on Sunday. The market employs around 14 staff members. Utilities
provides electricity, water, stormwater and wastewater. The facility was sold in 2022, however
work preceding that sale can be compared to use at the time of sale as well as subsequent use
to demonstrate savings associated with EWB projects. Multiple facility assessments before the
sale isolated opportunities to save electricity.
Projects
A total of 12 EWB projects were completed over a 10-year period at Beaver’s Market (now
Fresh Market), with an additional lighting project in 2004. These projects upgraded the following
elements:
• Lighting
• Refrigeration
• Gaskets
• Cooler lights
• Grocery
• Night covers and case lighting
Installation costs for the 2004 lighting project are not available, however total costs for
subsequent upgrades were just under $58,500. Incentives for all projects totaled just under
$28,000 (including $1,750 for the 2004 project). Total electric savings for these projects equals
166,853 kWh of annual savings, or $15,684 in annual electric utility savings based on 2024
commercial rates. This equals a 53% reduction in electric use as of 2021, just prior to the sale
(a 58% reduction over today’s use). The market is currently well under their projected EUI target
as set by the proposed Fort Collins BPS (EUI 120, proposed target 148).
Conn’s, 120 Bockman Dr.
Conn’s is a 46,070 square foot retail store built in 1991. As no assessment was done on this
property, there is limited additional detail available, however the property benefitted from
rebates.
In addition to a recent lighting project, they partnered EWB for a VFD upgrade. Their partnership
saved them nearly $47,000 in incentives paid toward a total of just under $57,000 in work. EWB
covered the entire cost of the lighting project and almost 30% of the cost of the VFD. The two
projects saved a total of just under 183,000 kWh annually, totaling $17,200 saved every year in
avoided electric bills. This building is well below its proposed BPS EUI target, having reduced
total use by 50% with two simple projects (EUI 23.6, proposed target for retail is 49).
VFDs save energy by helping motors operate at the most efficient speed for any given use.
They extend equipment lifespan by decreasing wear and tear and reducing maintenance costs.
That equates to significant savings, which can be realized more easily and affordably by
partnering with EWB for local rebates.
Hibachi Japanese Steakhouse, 1051 W. Horsetooth Rd.
Hibachi Japanese Steakhouse is a 6,200 square foot restaurant that opened in 2006. The
building was constructed in 1999 and is built with a wood frame covered in stucco with a sloped
tile roof. According to an EWB facility assessment, the small square footage of flat space on the
roof houses the mechanical systems and is accessed via a catwalk in the attic. The exterior
surface area is estimated to be made up of 20% windows where a large portion face east. That
exposure brings a lot of daylight into the dining area, which led the owner to install indoor
shading devices. The entrance to the restaurant is on the south side of the building and leads
directly into the bar on the west side and the sushi bar on the east side. About 10% of business
comes from sushi and the remainder from the hibachi. During the week, the restaurant is open
from 3 p.m. to 9 p.m., with extended weekend hours. Because most of the dishes served are
made in front of patrons, restaurant operations begin only an hour before opening. During the
week there are typically 12 staff members present; on the weekends there are 20. Utilities
provides electricity, water, wastewater, and stormwater services.
Projects:
Within the last 10 years, Hibachi Japanese Steakhouse participated in three projects: gaskets,
grocery, and sushi bar grocery. EWB provided just below $6,000 in rebates for total project
costs of $6,630. These projects save 37,245 kWh annually. That equates to $3,500 in electric
savings every year, using 2024 commercial electric rates. These simple projects reduced the
restaurant’s total use by 33%, and its current energy use is well under the proposed BPS EUI
target (current EUI is 197, proposed EUI target for restaurants is 219).
University Plaza: Wilbur ’s, Whole Foods, King Soopers, and more
This 230,209 square foot strip mall houses large supermarkets, a liquor store, a gym, and
various retail stores. Seven of the businesses within the building’s footprint have
participated in the EWB program, contributing to significant savings across the high-use
building. While this building must comply with the State of Colorado’s BPS policy, a case
study is provided given the variety of projects.
To the north end of the building, Whole Foods Market and Wilbur’s Total Beverage have
participated in 12 projects, including:
• Lighting and sign lighting
• Heater controls and electronically commutated motor (ECM) evaporator
• ECM in walk in and display cases
• LED cooler lights
• RTU controller
• VFD motors
• Gaskets (refrigeration)
• Display case doors (refrigeration)
Incentives paid for these projects total $66,442, of $197,608 total project costs before
incentives. Annual electric savings from these projects are 525,096 kWh, or the equivalent of
$49,360 annual electric costs.
Toward the center of the building, Office Max, Petco, and Miramont/Crunch Fitness completed
six projects since 2017 focusing on food service (Petco) and lighting, and one Midstream
Cooling Program air conditioner. These projects received rebate savings of $32,270 and
achieved 163,131 kWh of annual savings, or the equivalent of $15,334 in annual electric
savings. While the cost of the air conditioner is unknown due to the nature of the Midstream
Cooling Program, the installation cost of other rebated measures was $57,387.
To the south end, King Soopers participated in seven rebate offerings, while the business at
2407 S. College Ave. just to the south of King Soopers also benefited from the Midstream
Cooling Program. The King Soopers projects included cooler lights, gaskets, and lamps.
Total rebates equaled $29,417 of a total installed cost of $56,408 (minus the air conditioner as
its sale price is unknown). Electric savings from these projects equal 382,284 kWh per year, or
$35,935 saved in electric bills annually (based on 2023 commercial electric rates).
In total, the whole building has saved 1,070,511 kWh, equal to over $100,680 in annual bill
savings. Total out-of-pocket costs after rebates was $183,274 (excluding the unknown air
conditioner costs). In total, the projects above reduced overall building electric by about 17%.
This building is meeting Fort Collins’ proposed BPS target (current EUI is 101.8, proposed EUI
target for strip malls is 103).
Glossary of Terms
ECM:
An ECM (electronically commutated motor) lowers the total electrical consumption of an air
conditioner or furnace. It helps maintain proper air flow through the system by sensing its
operational status and controls the speed of the evaporator fans.
ECM motors contain a microprocessor, which is the key component of what makes them able to
provide better efficiency. This microprocessor controls the motor to regulate air flow. The motor’s
rotations per minute will either ramp up or down to keep air flow steady. This allows an air
conditioner and heater to work at maximum efficiency. Rather than the motor running the fan at
the same constant high rate, it modulates to adjust for conditions, sometimes running at lower
speeds and using less power than full load. On top of this significant way to save energy, an
ECM motor uses less wattage than a standard motor. Savings occur from full speed runtime
hours reduction and waste heat reduction to the refrigeration system.
VFD:
A VFD (variable frequency drive) saves energy by helping motors operate at the most efficient
speed for any given use. They extend equipment lifespan by decreasing wear and tear and
reduce maintenance costs. Fans and pumps that are turned down just 10% can save up to 25%
in energy costs. In most systems, reducing speed by 50% can cause a 75% drop in energy
consumption. That equals big savings, which can be realized more easily and affordably by
partnering with EWB for local rebates.
Gasket:
A gasket is a common term for any seal between two surfaces. A refrigeration gasket is a
flexible, elastic strip that creates an airtight seal around the edges of a refrigerator or freezer
door. Refrigeration gaskets are a very important part of a walk-in cooler or freezer’s
performance. Gaskets are responsible for sealing walk-in doors and panels to stop any air
infiltration. When gaskets are not working properly, refrigeration units must work harder to keep
their temperature – which in turn generates higher energy bills and wear and tear on equipment.
Gaskets help maintain temperature and improve energy efficiency by reducing the amount of
warm air that enters a cold area, and vice versa.
RTU controller:
A rooftop unit (RTU) controller is a retrofit technology that provides better functionality and
energy savings opportunities for existing RTUs. The U.S. Department of Energy estimates
anywhere from 15 to more than 50% energy savings can be achieved with a one to four year
simple payback potential. There are several features of advanced RTU controllers that
contribute to savings, mostly from the implementation of variable or multi-speed control of the
supply air fan, demand controlled ventilation (which uses CO2 levels in the return air to adjust
the outside air control), and improved economizer control. Some technologies allow for demand
response, web-based remote monitoring, and automated fault detection and diagnostics.
LED lighting:
The most common EWB upgrade over the years has been lighting, given its short, simple
payback, ease to upgrade, and aesthetic value. Light-emitting diode (LED) is an energy-efficient
technology that lasts longer, is more durable, and offers comparable or better light quality than
other types of lighting. The high efficiency and directional nature of LEDs makes them ideal for
many industrial and commercial uses. LEDs emit very little heat, unlike incandescent bulbs
which release 90% of their energy as heat and CFLs which release about 80% of their energy
as heat. LED lighting products also last much longer than other lighting types. A quality LED
bulb can last three to five times longer than a CFL and 30 times longer than an incandescent
bulb.
Historic Examples
Many case studies have been documented over the years to demonstrate savings along with
other positive benefits resulting from efficiency projects. As a part of the City’s efforts to outline
achievable recommendations for a local BPS, Utilities chose to complete case studies for the
most common property use types covered by the proposed Fort Collins BPS (office, multi-family,
retail, and strip mall). Those case studies are available at ourcity.fcgov.com/bps.
EWB also publishes case studies from Fort Collins as well as the other partner jurisdictions
(Estes Park, Longmont, and Loveland). These case studies demonstrate various property types
that have participated with the program and benefited from rebates. Those case studies can be
found online at efficiencyworks.org/resources/business-resources.
Utilities has also put together historic case studies, documenting further local partnerships with
EWB. These short, concise studies provide further documentation of the historic success of
EWB, and can be shared upon request.
Through decades of partnership with the community, Utilities has provided rebates and
incentives directly to the community, technical support financing for on-site audits and energy
advising, and direct to manufacturer benefits to reduce the cost of efficient technologies.
These programs have provided many examples of ways local buildings can improve their
efficiency. However, the projected future impact of economic-based approaches to building
efficiency are far short of the outcomes our community tasked the City to achieve in the Our
Climate Future plan. Utilities strongly recommends this regulatory approach to meet Our
Climate Future goals; indeed, such an approach is the only way OCF targets could be met
goals.

Question: “What other concerns do you have about connecting to a system that allowed Fort
Collins Utilities to manage a battery storage system at your home?”
“I would not be interested in
having the city control my
battery at all. You should
incentivize us to act in the
way you’d like.”
“(I) Do not want
anyone to
manage my
system but me.”
“Battery technology, at this time,
has a short lifespan...on the
order of ~1500-2000 cycles
depending on how it is used. I'd
want to restrict that cycle use
to only peak-power times,
otherwise the cost benefit
greatly reduces.”
“I am not worried about
outages, we’ve had just 4
of any significant length in
30 years, all under 6 hours
max… I like the peak
shaving aspect for the
utility and us overall.”
“Don’t want it won’t use it; if
mandated I will shut the system
down. It is mine not yours.”
“Security - what
if Fort Collins
Utilities was
hacked? What
could happen to
my home and
system?”
