Building Envelope

Air infiltration is a significant source of heat loss and heat gain in buildings and results in higher energy consumption to compensate for the additional heating and cooling loads.  Infiltration is most prominent when the air pressure inside the building is much greater than the air pressure outside the building, which is commonly the case on windy days.  Research has shown that up to 30% of heating and cooling requirements can be attributed to air infiltration.  Infiltration commonly occurs at joints in exterior windows and doors, as well as joints in walls from the floor all the way up to the roof.
