home energy audits

During our home energy audits, e3 Power uses a variety of high-tech, state-of-the-art tools and instruments to identify the key areas where your home is wasting energy. Included in our audit reports are our recommendations for the most cost-effective ways to improve energy efficiency, comfort, and indoor air quality.

Energy audits for commercial buildings

E3 Power is a highly recommended, certified commercial building energy audit consultant in Denver. We offer residential audits and commercial energy audits for owners and managers of commercial buildings who are interested in achieving an energy-efficient business space, reducing overhead costs, improving occupant comfort, and reducing environmental impact.

Blower door testing

Blower door testing is the best way to measure air leakage in a home or building. It’s an integral aspect of an energy assessment, and in many cases, blower door testing is required by building code.

RESNET HERS Rating

The Home Energy Rating System (HERS) Index is the INDUSTRY STANDARD by which a home’s energy efficiency score is measured. It’s also the NATIONALLY RECOGNIZED system for inspecting and testing a home’s energy performance—over 3 million homes in the United States have been HERS rated.

Manual J/S/D/T Calculations

Many HVAC contractors skip Manual J, S, D, and T calculations, preferring to rely on estimates rather than put in the effort to correctly size and design a new HVAC system. But e3 Power has seen enough poorly designed and improperly sized heating and cooling systems installed throughout Colorado to know the importance of taking the time to do the job right.
