E3Power home energy audits Denver, CO

We at E3 Power use the “building as a system” strategy along with diagnostic testing to provide energy saving options to increase the comfort, health, safety, and the durability of your home. We can also analyze your attic insulation levels in order to qualify for Xcel Energy rebates.

Blower Door Assisted Air Sealing

A blower door is used to depressurize the building and simulates an approximate 20mph wind on all sides of the building. This aids us in finding areas of the exterior walls that provide paths for energy exchange to the outdoors. With low expansion spray foams and caulks we correct these issues to increase the overall comfort and energy efficiency of your home.


New energy efficient recommendations for insulation R-values in Colorado are: Attic R-49, Wall R-18, Floor R-25, Crawlspace R-19, and Basement R-11. We help to reach these standards by assessing current insulation levels and adding additional insulation using a variety of methods and materials based on the location of improvement.

Attic Insulation

This photo shows our insulation vacuum. The large "burrito" in back is full of old insulation. Removing the insulation gives us full access to the attic floor allowing us to air seal exceptionally well!

This is a photo of a combustion flue that was insulated prior to us starting work. While insulating ductwork is a good idea, insulating the flue pipes is not, as they get very hot.
