Our Approach to Energy Efficiency


Our identity is in our people. REenergizeCO team members diagnose residential homes to determine if there are any major energy inadequacies causing high bills or discomfort. Our diagnostic process involves a very analytical approach starting with a full thermal energy audit with the use of a blower door test. This testing measures exactly how much the house is leaking, or how much insulation is or isn’t existing, and how the building envelope is performing. We take into account the homeowner and their behavior as well. We take 12 months of utility bills (if available) and plug them into our software along with all of the data points collected on the audit to make a custom report full of recommendations on how to improve the efficiency of the home.

Because we are the team diagnosing the house, we want to be the team making the improvements as well. Our install crews are led by experienced crew leads who are on site during the install process. We have the capability to install every type and make of insulation on the market. Air sealing homes to make them less drafty, and insulating the home in the right places with the right material is what we do.
