The Denver Energy Challenge helps 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 until the work is complete.

Participants in The Denver Energy Challenge are saving an average of 23% by doing upgrades. 

To date over 11,490 residents are saving money and energy because of the Denver Energy Challenge.

Start Here

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 Department of Energy's BetterBuildings Neighborhood Program in 2011. This funding was derived from the American Recovery and Reinvestment Act (ARRA).

The Denver Energy Challenge 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. 

Getting started is simple. You drive the process and timing, we provide expertise and support.

  1. CONTACT US - Call 720.865.5520, Monday - Friday 8 a.m. to 5 p.m. or contact us online. We’ll set you up with your own Energy Advisor. Please ensure you are a resident of the City & County of Denver using the Denver Address Locator.
  2. GET AN ENERGY ACTION PLAN - Your Advisor will contact you to schedule an appointment (home visit, phone, Skype or Facetime) where you can discuss your current energy use and identify means for improvement. Your Advisor will then give you a tailored Energy Action Plan to achieve your goals and get you from start to finish. 
  3. TAKE ACTION - After you review your Action Plan, Energy Advisors can help you decide what projects to implement to make the greatest impact for the cost. Your Advisor will support you in applying for all applicable rebates/credits/loans, connect you with vetted contractors if necessary, and help you to review bids to ensure the process is easy and affordable.

When you sign up for the Denver Energy Challenge you will be assigned one of our Advisors. They provide free, non-regulatory advising to help you to identify means for making your home more comfortable, affordable and efficient.

Here’s what an energy advisor can do for you:

  • Answer any questions you have about energy savings
  • Meet in person or over the phone to identify energy saving measures
  • Draft a free, tailored Energy Action Plan for your home
  • Review a previous energy audit or help schedule one. (Note: An energy audit is a separate, more detailed plan performed by a contractor to determine specific areas of heat loss. Your energy advisor can consult as to whether you might want to take this additional step to meet your goals.)
  • Prioritize energy upgrades based on your goals and budget
  • Locate rebates, financing and help you apply
  • Provide a list of pre-screened Contractors
  • Compare and review contractor bids
  • Serve as a sounding board throughout the upgrade process

  • What does Free Energy Advising mean?

Energy advisors are a free, neutral resource provided by the City. They are available to assist you at any point when making your energy improvements.

  • What if I just need financing? Do I have to meet with an advisor first?
No. Contact the us directly at 720-865-5520 or via the “Contact Us” form mentioning that you simply need approval for financing and an advisor will help guide you through the approval process. Note: You must be approved for financing before you begin work with a contractor.
  • Does my advisor also perform a home audit?

No, your advisor will provide you with an Energy Action Plan but you may choose to get an energy audit in addition.  An energy audit is a more comprehensive 3-4 hour test of your home that is performed by a certified energy auditor. It will identify specific areas of heat gain or loss, air penetration and ductwork leaks that can define the scope of work for a contractor. Home audits currently cost $185 or more. Click here to see how your advisor can assist you throughout the process. 

  • How do I know if my home is located in the City and County of Denver?

Having “Denver” in an address does not guarantee that your home is within City/County limits, use the Denver Address Locator to verify that you are within the City/County boundary.

In order to provide advising to all of our Denver residents the City & County of Denver has put in place a contract to provide phone and in-person advising to our participants.
