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 Principal began blower fan testing in 1997.

Our testing expertise extends to apartment buildings, condominium towers and commercial or institutional buildings. Testing of the whole building is required at the end of construction, and we are also able to conduct mid-construction testing to help you evaluate your construction techniques and building envelope.

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

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

E3 maintains one of the largest inventories of equipment for airtightness testing in BC. We have the capacity to move up to 114,000 cfm of air—adequate for very large buildings.

We also offer education and consulting services on air barrier systems and construction details.

We don’t just test buildings; we help our Clients meet their airtightness targets.
