Home Energy Audit

What Is A Home Energy Audit?

The home energy audit is performed to determine how a building structure is wasting energy. Accurate testing of a business or home residence is done with a thorough examination. A thermographic scan and blower door test uncovers areas where energy is wasted. USA Construction uses high quality thermographic scanners to determine where you are loosing heat and cool air, and where you need put your energy saving dollars.

Thermographic Inspection

The testing uses infrared video and images to measure surface temperatures. The camera records temperature variations that range from white for warm and black for cold. This information helps the auditor determine whether additional insulation is required for the structure. Interior thermographic scans are very accurate in determining where heat loss is occurring. The test is usually done during the blower door testing for the most accurate results. 

Thermographic inspection can be completed through several types of infrared sensing devices. A thermal line scanner detects radiant temperature along a line with any variations. A point radiometer measures temperature readings wherever the auditor pans the area. A thermal imaging camera produces dimensional images that show heat loss with the most accuracy.

Blower Door Testing

This test is used to determine the tightness of the building. A high performance fan is mounted into an exterior framework to pull air out of the building. This lowers the air pressure inside. All unsealed openings inside can be located from the vacuum produced by the blower fan. The blower door-testing unit consists of the high-speed fan built into a flexible panel that will completely seal the exterior framework. A gauge measures pressure variations on the interior and exterior of the building. Manometer and hoses are used to measure airflow. The data collected by the auditor can then be used to make accurate determinations of any leaks inside.
