“Optimize Air Quality” | But Why?

In Canada, air quality might be something that we take for granted. We generally live in sprawling communities with low density and lots of natural environments around us.  So the perception of air quality issues might not be top of mind. But when we take a look at the increasing complexity of air quality in homes that are being built more airtight, the conversation needs to dive deeper: 

Typically, traditional homes are very leaky, and when your furnace and bathroom fans kick on, air exchange happens through intakes, exhausts, as well as hundreds of small cracks and gaps in the building envelope. Believe it or not, the total volume of air in most homes is constantly changing over with outside air. As this happens in the winter, you are losing immense amounts of heat and beneficial humidity. In the summer, you lose your conditioned air and pull in hot/humid outside air. Not to mention the dust, pollutants, and allergens that are relentlessly being cycled through your home. 

Passive Houses are designed to avoid leakages in the building envelope, thus boosting energy efficiency while preventing draughts, moisture damage, and poor air quality. Airtightness relies heavily on the calibre of craftsmanship involved in the build; ultimately, exceptional airtightness directly translates into exceptional energy efficiency and the ability to control the continuous supply of fresh filtered air. A key component of this continuous fresh filtered air is the heat recovery system (or HRV). Often coined as the “whole house fresh air machine”, an HRV recovers up to 90% of the heat traditionally lost from exhausting stale air from the home. Continuous fresh filtered air is a key element to overall homeowner health – and if we can provide it while being extremely energy efficient at the same time, it’s a win-win!
