Step 3 - Indoor Inspection
Main Level, Basement, & All Secondary Levels of the Home
Examine thermostat, furnace, water heater, basement wall and band joist
insulation, ducts for sealing and insulation, window sealing, locking
and glazing, weather stripping for doors and windows, flooring, washer
hoses and overall character of all appliances. The auditor will also
inspect the attic to look for air sealing and insulation opportunities
as well as indoor air quality concerns.
Step 4 - Blower Door and Infrared Tests
Blower Door Test
Specialized diagnostic equipment is used to determine the air
tightness of the house, the total amount of air leakage of the
building, and where the air leaks are originating from in order
to save you money on your utility bills and improve the over all
comfort of the house. The blower door test also identifies moisture
condensation problems. During the test, a powerful fan depressurizes
the entire house and examines the rate that air re-enters the building
through unsealed cracks and other openings in the building envelope.
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 in order to save you money on your utility bills and improve
the over all comfort of the house. 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.
Step 5 - Combustion Appliance Zone Testing
CAZ Testing is a health and safety test that is important where combustion
appliances are in use. Tests are designed to insure that there is no leakage
of flammable fuels or combustion gases like carbon monoxide into the living
space and that combustion appliances are functioning in a safe and efficient
Step 6 - Review Results
The auditor reviews the initial findings with you. A more detailed
report is emailed to you within one week, with specific recommendations
to make your home more energy efficient.
