- verelo 7y agoI came here to say exactly this. I'm in Toronto Canada and just renovated a duplex, i was required to install ERV's to exchange the air. VOC's from off-gassing is unavoidable with present building materials, so the best we can do is replace the air as often as possible to minimize the impact. They're not expensive, and the impact to air quality is massive.
- lxmorj 7y agoAir leakage standards in which direction?
- swampthinker 7y agoBuilding envelopes need to be tighter
- lxmorj 7y agoGot a Netatmo CO2 sensor recently and i think that needs to be rethought. That shit builds up fast inside a well sealed system.
- swampthinker 7y agoThat's why there are requirements around installing an air exchange system.
