Impressive Results in Airtightness Testing

Red Door Energy Advisors performed a three-unit airtightness test on our EXOBuilding System using a Natural Resources Canada-recommended test procedure. Airtightness and efficient mechanical ventilation has proven to be one of the most cost-effective methods of providing comfort, ensuring envelope durability, and maximizing building energy efficiency.

The test results indicate the EXO building has air leakage of 3.08 air changes per hour at 50 Pa (ACH@50).  This is significantly more airtight than typical new buildings in British Columbia. Typical new residential buildings run about 5.5 ACH@50. Typical new commercial buildings run significantly higher. 

"This is an impressive result. New buildings of this size average 5.5 ACH@50 in BC." says Monte Paulsen, Certified Energy Advisor at Red Door Energy Advisors.
