NOTICE: The Denver Energy Challenge (DEC) program will end on Oct. 31, 2017.

DEC was designed to stimulate local economic growth, increase energy efficiency investment in Colorado and advance the state's energy independence through large-scale energy upgrades thanks to grant funding from the U.S. Department of Energy. As of October 1, 2017, more than 12,100 Denver homes had participated in DEC, saving enough energy to equal taking 5,105 cars of the road each or powering 33,725 ski lifts for one day.

Through this program, and other City agency efforts, we’ve achieved market transformation as originally intended in the grant, however our work is far from done. After October 31, this page will transition to focus on energy efficiency resources for residents and other innovative strategies to help Denver meet is climate goals. Stay tuned!

Additional Information

The City and County of Denver was originally a sub-recipient of a $25 million grant managed by Boulder County for seed funding from the U.S. Department of Energy's Better Buildings Neighborhood Program in 2011. This funding was derived from the American Recovery and Reinvestment Act (ARRA). DEC was designed to stimulate local economic growth, increase energy efficiency investment and advance the state's energy independence through large-scale energy upgrades.

DEC utilizes an advisor model to help residents make home energy upgrades easy and affordable. Free, neutral energy advisors work with Denver residents to identify energy goals; develop a tailored Energy Action Plan for each home; provide guidance on rebates, tax credits and low-interest financing; review bids; select a contractor and act as an expert resource throughout the project.

Over the past seven years, the program has helped more than 12,000 residents feel more comfortable at home, save money and conserve and average of 23 percent more energy.

The program is ending to make way for newer, more innovative residential energy initiatives. If you are a current DEC participant and have questions, please see the FAQ section below.

How can I get more information about this program change?

Please contact DEC Program Manager Julie Saporito at 720-865-5430 or with any follow up questions.


Are similar programs still available in Denver?

Xcel Energy has adopted Denver's energy advisor model and provides advising to all Xcel customers. Call 303-446-7910 or email for more information.


Will the City still offer energy loans?

Energy loans will still be available for Denver residents. The Colorado Energy Office offers a low-interest energy loan program that not only serves Denver, but the entire state of Colorado.


If the program is free, why is it ending?

While DEC is free for Denver residents, the costs to administer the program are not sustainable for the City. In addition, Xcel Energy has adopted the energy advisor model that provides customers with the same information about utility rebates and financing. Xcel Energy also has direct access to all Denver residents and their individual energy data. The City does not have access to this information and does not have the financial resources to reach all residents. The City will continue to work with Xcel Energy to help leverage resources and educate Denver residents about energy efficiency and solar energy opportunities without duplicating efforts. 


My existing DEC project will not be finished by Oct. 31. Where should I go for assistance after the program ends?

Xcel Energy has adopted the City's energy advising model and can provide advising to all Xcel customers. If you would like a DEC advisor to help connect you with an Xcel advisor, please contact DEC staff before Oct. 31. After that date, please call 303-466-7910 or email for assistance.


Will the DEC contractor pool still be available?

The City no longer maintains a vetted list of contractors. However, EnergySmart maintains a list of contractors that wish to obtain mentoring and quality assurance checks to improve the quality of their work. 

Additionally, Xcel Energy maintains a list of energy efficiency contractors.

Regardless of the contractor you select, make sure the contractor is licensed within the City and County of Denver and obtains the necessary permits. Verify your contractor is licensed.

Your advisor has information on all of the latest rebates and tax credits to bring down the cost of home energy projects.

Residential Rebates

Xcel Energy is the administrator of rebates for Denver Residents. We recommend checking with your energy advisor to see which rebates are available through Xcel Energy for the upgrades you choose to do.

Residential Tax Credits

View the Database of State Incentives for Renewables and Efficiency to see if there are available tax credits for Colorado.

The following can help you improve energy efficiency in your multi-family building:

  • Xcel Energy:  Offers multi-family building efficiency services and can provide a no-cost audit, direct installs (showerheads, lamps and aerators) along with helping you Implement capital improvements for boilers, lighting, etc. To learn more visit  
  • Benchmarking Ordinance: Starting in June of 2017, large buildings over 25,000 square feet are required to report their energy performance to the City and County of Denver’s Department of Environmental Health. Each building will be rated using a 1-100 score to create an apples-to-apples comparison, much like a MPG sticker does on a car. The ordinance hopes to reduce the commercial building sector’s greenhouse gas emissions, which currently represent 57 percent of the City’s totals. Visit to learn more.
