To ensure that each house is up to Garner Custome Homes’ standards, two tests are performed by HERS raters. The blower door test is conducted to verify the building envelope is sealed to Energy Star requirements. The second test is a duct leak test to ensure that all the duct system has a minimal amount of leakage. Conditioned air that is blown directly into the attic due to poor sealing methods is typically a major area of inefficiency.
Blower door tests are performed using special variable-speed fans. All windows and doors are closed, and the fan is installed in the front door with a special air-tight seal. As the fan is turned on, the energy auditor will monitor the flow of air through the fan, as well as the air pressure inside your home.
Because your home is sealed and evenly pressurized, it’s easy ton find out exactly where air leaks are occurring. In most cases, you can feel air leaks with your hand or see them with the use of a tissue.
The Duct Blaster® is used to pressure test your duct system for air leaks, much the same way a plumber pressure tests your water pipes for leaks. After temporarily sealing the registers and grilles, The Duct Blaster® fan is connected to the duct system to force air through all the holes and cracks in the ductwork. A precise leakage measurement is then made using the airflow and pressure monitor connected.
The HERS Index is commonly referred to as a MPG (miles-per-gallon) value for a home. The HERS Index is a nationally recognized system for analyzing and scoring the performance of a home from an energy efficiency perspective. Once the analysis has been performed, the HERS Index score is determined and a detailed report given on the home’s efficiency strengths. By using diagnostics such as a blower door test, duct leakage tester, combustion analyzer, and infrared cameras, the HERS Index test identifies potential pitfalls, while taking into account the specific structure of the home, and how the design can affect efficiency.
Garner Homes obtains HERS Index data on all new mechanical systems and homes, to insure maximum efficiency for each project.
