Project Description
Project overview
For this PassivHaus commercial building in Wakefield, Quebec we designed and pre-fabricated a unique building enclosure system. All structural components were manufactured off-site, including; R-76 exterior wall panels; raised-heel, long-span roof trusses (insulated with R-100 blown cellulose); and i-joist floor panels.
Project highlights
- Exterior walls utilize an internal layer of foil-faced PIR rigid-foam insulation for air and vapour control.
- A 10” thick layer of extruded polystyrene insulation was used to thermally isolate the footings and floor slabs from the ground.
- The building exceeded the PassivHaus standard of 0.6 ACH/50 on the first blower door test, a testament to the quality of the construction.
