Home Energy

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 efficienct can improve comfort while reducing your energy bills. It can also help the City meet its climate goals while protecting public health.

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. 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.
