- lostmsu 8y agoI am curious, with better insulation, would not CO2 levels inside be too high for comfortable living? When I close door to my office, it quickly grows to 1300ppm, and my office has giant holes.
- rightbyte 8y agoYou have ventilation with heat exchange.
- lostmsu 8y agoHow does that work?
- reilly3000 8y agoThe basic standard of Passive House design/retrofit is making sure the structure is airtight. There is a standard test called the blower-door test to see how much air is escaping through parts that should be sealed. The heat exchanger pulls in fresh outside air and filters it thoroughly. It can 'passively' adjust the air temp by warming it with household heat recycled from cooking, showers, etc, or selectively pulling in cooler air. The net effect is dramatically better indoor air quality with minuscule utility bills.
