The Construction Source

DECEMBER 2020 Recently, as previously mentioned,BlueWaterConcepts wrapped up construction on Squamish’s first certified Passive House. Mike and his team are particularly proud of the results they achieved there – especially the ACH rating they achieved. According to Mike, that project had a final blower door test of 0.19 ACH (air changes per hour, as in the number of times in an hour that a home refreshes its entire volume of air). Conventionally built homes tend to average a rate of 4 to 10, while Energy Star homes can rate around 2.5. The Passive House benchmark is under 0.6 ACH. At that rating, no condensation will form within wall or roof cavities, which keeps air quality strong and the home and its inhabitants healthy. So the home is well insulated and energy-efficient – but at the same time, it has a thoughtful and effective HRV (heat An emphasis on efficiency
