475 High Performance Building Supply (475), Oct 2016 – present, Business Development – Eastern Canada | Specifications. 475 provides essential building knowledge and components to support the transformation of US and Canadian construction to high-performance, low-energy buildings, and Passive House buildings – the gold standard that results in more comfortable, healthy and affordable buildings while reducing energy usage up to 90%, without a lot of complicated technology. Our focus starts at airtightness – the single most important factor in building thermal performance. We also provide related components such as vapor control membranes and tapes, ecological insulation, PH-certified roof openings, and PH energy balance software. In addition to several detailed trainings, we offer numerous free knowledge resources including videos, specifications, details, writings, conference presentations, and other aids. Passive House and other high performance building methodologies are no longer a fringe concept – the market has caught on, and 475 is there to support the transition.
