Just open a window a crack. The CO2 drops rapidly.
The problem with ultra insulated homes are that C02 and moisture get trapped. So then you need filtered fresh air, and then heat recovery.
- XorNot 5y agoMy windows face the street - and that's the issue, heat loss in winter is a big deal. And I have to actively monitor in order to know I should do it - this isn't something you really think about, and its terrible when you're in the flow while working. There's also other reasons - for example I want to ensure the flow of air through the house concentrates and exits via the bathrooms and kitchen.
- breput 5y agoIt isn't quite that easy. Even if there aren't impediments to opening a window a crack, it is not guaranteed that passive measures will reduce CO2 levels. I've been tracking my home office's CO2 level for about a year and a half and obviously opening a window helps, but there are certain conditions (pressure, temperature, wind?) that require fans to normalize the levels.
