Air tightness testing of large commercial and residential buildings is a common practice required for low carbon, near-zero energy building codes and volunteer efficiency building programs like LEED and ENERGY STAR. Across Canada, many provincial building codes will soon require air tightness testing of large buildings prior to occupancy.
Air tightness testing informs building designers on how much air is escaping in and out of a building through unseen holes. Through testing, a building air leakage curve can be created to determine how a building reacts to natural and mechanical pressure differentials. Induced pressures are generally caused by:
Preservation of the building enclosure through limiting moisture transport via air leakage
Improved energy efficiency, lower utility costs
Lower heating and cooling loads, reducing the sizing of HVAC equipment and ductwork
Greater occupant comfort through minimizing drafts, noises and odours from exterior and adjacent zones.

We have an extensive inventory of air tightness testing equipment and are able to test according to the following standards for large buildings:
Below are some of the various building codes and programs we provide testing for:
“We rely on Building Knowledge for all commissioning and verification of all Great Gulf low-rise projects. This includes all airtightness testing and all pre-development energy modelling on drawings for permits. Building Knowledge also provides in-house training for service, sales staff, and construction on the benefits of how to build, sell and service energy-efficient homes.”
