Building Air-Tightness Testing
Air leakage can cause a significant amount of energy loss through the building envelope. As such, the airtightness of a house can impact its efficiency, well-being and comfort of the occupants. Performing blower-door test is the best way to measure how leaky your building is. This test is used to determine the equivalent leakage area at 10 Pa and the air changes per hour at 50 Pa.
At Meta Energy, our NRCan-certified Energy Advisors can perform blower door tests as part of the EnerGuide Rating requirement or as part of the mid-construction air barrier performance.
BC Step Code Compliance
Based on the BC Building Code, new buildings can comply choosing either: a) prescriptive path; or b) performance path.
Prescriptive path can be achieved by satisfying all the requirements of building code where as the performance path uses energy modeling to satisfy the performance of the building compared to a reference building.
BC Step code is designed based on the performance path. There are 5 steps for part 9 buildings. Currently, BC Building Code requires Step 1 which can be achieved by following prescriptive path. However, as the building code is evolving the higher step will be the minimum requirement which would be harder to comply using prescriptive path.
At Meta Energy, our NRCan-certified energy advisors and building performance specialists can help you by performing blower door tests at mid- and final-stage of construction, pre- and post-construction energy modeling, and generating required reports.
