The houses I’ve seen control the exchange rate with air quality sensors - so, if you are having a party, the ventilation speeds up, and when the house is empty it slows down.
That said, in the US the ACH rate is recommended at 0.35 by ASHRAE, see https://www.epa.gov/indoor-air-quality-iaq/how-much-ventilation-do-i-need-my-home-improve-indoor-air-quality https://www.epa.gov/indoor-air-quality-iaq/how-much-ventilat...
- Terry_Roll 5y agoYeah but its not measuring the quality of the air. Houses are just passive particulate collecting devices, ie particulates travelling on the air outside, move into the house, meet a stationary or slower moving body of air, lose momentum and velocity and thus succumbs to the effects of gravity and hits a surface. Considering woman have traditionally been the one's cleaning the house for the living abode for hundreds of years, why havent they come up with something better to filter the air inside a property seeing as there is this push to get females into STEM?
