Energy Efficiency Resources for Denver Residents

Homes in Denver come in a variety of shapes and sizes. More importantly, how we use energy at home varies throughout the year due to the change of season, number of residents or how much we pay for energy. Making your home energy efficient can improve comfort while reducing your energy bills. It can also help the City meet its climate goals while protecting public health.

Unsure where to begin? Consider an energy audit to assess your home’s energy use before beginning projects. 

A home energy audit is a 2-3 hour diagnosis of your home performed by a certified and licensed auditor. The diagnostic tools used during an audit (blower door and infrared camera) are used to help diagnose a home when you can’t see issues with the naked eye. After the audit is complete, a report will identify opportunities to improve your home now, and into the future when it’s time to replace appliances such as your heating or cooling systems.
