Energy Audit Glossary

In an effort to extend our customer service to our online customers of the Greater Las Vegas, Nevada area, Air Supply Heating and Air Conditioning has compiled a glossary of terms and phrases associated with energy audits.
Air Sealing: Air sealing is referenced to the application of materials, such as caulk or foam, to stop airflow in cracks, gaps, or holes of a building.
Blower Door Test: A test used to measure a building’s air-tightness and locate any air leakage paths. Mounting into the frame of an exterior door, a blower door is a powerful fan that moves air in or out of the building; the air pressure inside changes to exaggerate air leaks through unsealed cracks and openings.
Building Envelope: The physical separator between the interior and exterior of a building; components of the envelope are typically: walls, floors, roofs, fenestrations and doors.
Combustion Safety Test: Combustion safety is the general term for evaluating fuel-burning equipment in the home. In general, these procedures include checks for fuel leaks, carbon monoxide, and to ensure that waste gases exit the home through the chimney or venting system.
Diagnostic Tests: Various procedures used to collect data and assess the performance and efficiency of components of the home using specialized testing equipment, including blower door testing and combustion safety testing.
Ductwork: A network of metal, fiberboard, or flexible tubes throughout a space which disperses treated air from an HVAC unit throughout the building.
