Services

Your Home Energy Report provides an energy ranking compared to other homes, a savings estimate, and unbiased, cost-effective upgrade advice. Overall, it paints a clear picture of how your home uses energy and where you can improve. Some services we provide are:

1. Blower Door Test

Professional energy auditors use blower door tests to help determine a home's airtightness.

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.


Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.

2. Combustion Appliance Zone Testing

CAZ Testing is a health and safety test that is important where combustion appliances are inuse. Test are designed to insure that there is no leakage of flammable fuels or combustion gases into theliving space and that appliances are functioning in a safe and efficient manner.

3. Infrared Thermal Image Scan

Using an infrared thermograph, a special infrared camera, the auditor can identify where the building is better insulated, and where opportunities exist to improve insulation or air sealing. By capturing temperature variations of the building's surfaces using wavelengths that are invisible to the naked eye, the camera identifies "hot" and "cold" spots in the building envelope, which allows the auditor to see what's going on behind the walls.
