BC Housing, Vancouver’s Building Bylaw, the BC Provincial Step Code and Passive House all require airtightness testing, and specific targets must be met. E3 has conducted blower fan testing since 2007, and our Principals began blower fan testing in 2002.

Our testing expertise extends to apartment buildings, condominium towers and commercial or institutional buildings. We have the capacity to move up to 45,000 cfm of air—adequate for even large buildings. Testing can be performed on the whole building, or on a portion of the building if needed.

Our testing staff and supply of blower fans are supported by Retrotec’s software and training. Each one of our testing staff have successfully completed the Large Building Airtightness Training program through Retrotec.

E3 maintains one of the largest inventories of equipment for airtightness testing in BC.

If diagnosis of leakage areas is needed, we can perform that service using our fog machine or Infrared camera in conjunction with our blower fan equipment.

We also help educate and consult on air barrier systems and construction details. We help our Clients meet their airtightness targets.
