Denver Energy Challenge (DEC) offers low-interest loans to Denver residents making home energy efficiency improvements. The loans start at 2.75 percent through funding from the U.S. Department of Energy.

The steps to getting an energy loan:

  1. Enroll in the DEC, a free residential home efficiency program offered by the City & County of Denver’s Environmental Health Department. An advisor will assist through the loan process. There are no requirements for enrolling in the program. Enroll online at or by calling 720-865-5520.
  2. Get pre-approved - Apply for an energy loan online or over the phone in 10-15 minutes. A loan officer will then contact you with more information. A property appraisal is not required.
  3. Work with your energy advisor to determine the loan-eligible scope.   
  4. Start work! Loans are based on contractor quotes and payment is made jointly to the borrower and contractor, ensuring the work can begin before payment. You cannot fund projects already started by a contractor. 

If this home energy deal isn’t for you, but would like help understanding the best way to save money and energy at home, try the City’s Denver Energy Challenge program. A free and neutral energy advisor will start with a consultation and draft a tailored home energy report highlighting ways to make your home as comfortable and efficient as possible. The advisor can provide a list of vetted contractors, review bids, connect you to low-interest financing options and rebates and more.

To date, over 10,300 Denver homes are saving an average of 23 percent thanks to the city’s energy advising- you can too! For more information, visit the Denver Energy Challenge or call 720-865-5520.
