Energy Assessment

Home Energy Assessment – How Does Your Home Rate?

Your home works as a system where the insulation system needs to work in conjunction with the heating/cooling and air exchange systems. If you upgrade your home’s insulation or apply more air sealing to prevent heat and energy loss, you may have to make slight modifications to your heating/cooling system to address the amount of fresh air flow into the home.

The best way to ensure that your insulation system is working in conjunction with your home’s mechanical system is to have a professional contractor do a home energy assessment. A home energy assessment is a holistic approach to evaluate your home’s performance needs.

HERS Score: The Lower the Better

Blower door and other test results are analyzed to determine a home’s score on the Home Energy Rating System (HERS) index.

The home energy rating shows how energy efficient the home is compared to other homes. The index ranges from 0 to 150 – the lower the score, the more efficient the home. As a point of reference, a standard new home incorporating the latest energy efficiency standards is rated 100, while a typical resale home is rated 130.*

The Revitalize Home received a final score of 85, which means it is 15 percent more energy efficient than a standard new home and 45 percent more energy efficient than a typical resale home.

Blower Door and Smoke Test Reveals Air Leaks

A blower door test uses a powerful fan fixed into an exterior doorway to draw all the air out of the home and lower the air pressure inside. Higher exterior air pressure will cause air to flow back into the home through any unsealed cracks and openings.

A smoke pencil can be used to visually reveal areas that need to be addressed with insulation and/or sealant in order to improve the home’s overall energy efficiency. A blower door and smoke pencil test reveals air leaks that can be addressed with insulation and/or sealants.

Before & After IR Shots Show the Difference

Using an infrared (IR) camera, it's easy to see the marked improvement in energy efficiency installing insulation and sealant products from Dow made on the Revitalize Home. An IR camera measures the intensity of infrared radiation (radiant energy) being emitted by a given surface. It's an easy way for a trained specialist to identify insulation voids, air leaks, moisture intrusion, thermal bypasses and thermal bridges - without opening up the walls or ceilings for inspection.
