Energy Efficiency

Energy efficient buildings are more important than ever. Tighter building construction will improve air quality and reduce energy costs. Air leakage is caused by cracks or gaps in the exterior shell of the building.  Air can also get through the building envelope, as well as old and leaky doors and windows. Older buildings suffer from air leakage due to the lack of technology that is available today. Building wraps, sealants, foams, and tapes reduce air infiltration and reduce energy use. New and more advanced products and testing methods are routinely used in modern building design and engineering.

Air Infiltration Testing

Air infiltration testing hasn’t been a priority until recent years due to lack of awareness. There are several ways to determine if a building is losing air. Blower door, or pressurization testing can be done to determine a building’s airtightness. A blower door is a powerful fan that depressurizes the air from a building, lowering the air pressure inside. The outside air pressure then flows in through cracks or gaps in the building. Energy auditors can then determine the air infiltration rate for the building and seal the leaky areas.

Thermal Imaging

Thermal imaging is another way to pinpoint where there may be deficiencies in a building’s envelope. Energy auditors can use the thermal images to show exactly where there may be inadequate insulation, air leaks, moisture intrusion or water damage.

As the price of energy rises, air infiltration testing is becoming extremely important to help keep energy costs as low as possible. Architects and engineers are using these techniques in their design to help prevent air and pollutants from entering a building.
