Denver City Energy Project: Unlocking the Value of Building Efficiency

The buildings where we live and work present a massive untapped opportunity for energy cost savings, economic development and reductions in greenhouse gas pollution. The goal of the Denver City Energy Project is to unlock $1.3 billion in energy savings and 800,000 metric tons of GHG emission reductions, the equivalent of 73,000 homes energy use for one year.

The first step in improving energy performance is to measure it. Benchmark your building using ENERGY STAR's Portfolio Manager tool and then share your score with the city to enroll in the Denver City Energy Project. The city is leading by example by benchmarking over 7 million square feet of its own buildings and committing to cutting their energy use 20% by 2020. Printable summary of project and enrollment

The benchmarking program launched on October 28, 2014! Press Release

The Denver City Energy Project will help the citizens and businesses of Denver:

Save Money.  Buildings use a lot of energy, so utility bills are a significant cost for owners and tenants.  An estimated $340 million of potential investment in energy efficiency could yield $1.3 billion in energy savings[1]

Stay Competitive.  Not only would the potential investment in energy efficiency create 4,000 jobs in Denver.  Energy efficient buildings will make Denver an even more attractive place to do business.  Tenants are starting to look for efficient buildings because they are cost effective, more comfortable, and in line with corporate sustainability initiatives.  Today efficient buildings already have occupancy rates that are 1-18% higher than their standard counterparts[2].

Do Denver’s Part for the Climate.  Over 64% of Denver’s carbon emissions come from commercial and multi-family buildings[3].  The Denver City Energy Project aims to cut that by 18%. 

Through meaningful engagement of stakeholders we are working on the details of how to meet these goals.

1 "United States Building Efficiency Retrofits: Market Sizing and Financing Models." Rockefeller Foundation and Deutsche Bank Group. March 2012. Numbers scaled to City and County of Denver.

2 "Assessing the Value of Green Buildings". Insitute for Building Efficiency. Johnson Controls.

3. 64% is based on Denver's core emissions, which are those which the City has the greatest opportunity to influence. If expanded emissions such as those associated with food and air travel are included then the percentage of total emissions attributable to buildings is lower.

The first step in improving energy performance is to measure it.  Step on the ENERGY STAR scale to benchmark your building - and share the resulting Portfolio Manager score or EUI of your building with the city. 

In exchange we will:


  • Put your building on the list of enrolled buildings or interactive map (under development).
  • Give you engaging information to share with your tenants telling them you’ve enrolled and what they can do to help improve the building’s performance even further (under development).
  • Use the data we collect to inform the design of additional building efficiency programs.  (The city really needs your help here!  We have very little data on how different types of buildings are performing today.  Its like trying to solve the childhood obesity epidemic when we only know their total weight.  If you don’t want us to share your building’s score or EUI publically you will have that option. The DCEP Portfolio Manager account is privately owned and managed to ensure your privacy upon request)

These building owners, managers and operators have all taken the most fundamental first step to good energy performance. They have benchmarked their performance using ENERGY STAR Portfolio Manager and shared the resulting score or EUI with the city. We thank these buildings for helping Denver unlock the value of building efficiency! (Soon the list will be clickable with more information about each building.)

Benchmark the overall energy performance of your building with ENERGY STAR portfolio manager.  Find out your ENERGY STAR score or EUI of your building and enroll in the Denver City Energy Project. Get ENERGY STAR certified if the score is over 75.

Tools to find out the cost effective energy efficiency improvements you can make to your buildings structure and systems include:

  • Asset Score:  The DOE developed Asset Score Tool takes only 6-8 hours to complete and evaluates the physical characteristics and as-built energy efficiency of buildings. The Asset Scoring Tool will identify cost-effective energy efficient improvements that, if implemented, can reduce energy bills and potentially improve building asset value.
  • Audit:  Energy audits are a more detailed analysis of energy usage within a building or facility and its contained equipment.  The results of the analysis are recommendations for energy efficiency improvement measures that could be undertaken in the buildings as well as a financial analysis for each identified measure.
