It's more efficient to air out by opening the windows fully and creating a draft for a few minutes several times a day than to leave the window cracked when it's colder outside.
- crazygringo 4y agoNo it's not. CO2 levels build up higher than I want within half an hour so I'd have to be doing that all day long. And it would result in a periodically freezing apartment. It's much more efficient for me to keep it open a crack.
- titaniumdafodil 4y agoDo you have central air, and keep the fan running? I've experimented with this at our place and doing a full cycle for 5 minutes, then turning the fan to "on" rather than "auto" and closing all doors and windows will keep it below 700 everywhere for about 6 hours. Otherwise the second floor climbs into the 1000's while the first floor stays around 500
- shafyy 4y agoI mean efficient in terms of heating/energy, not CO2 levels.
- thadk 4y agoI got the window unit version of https://www.openerv.org https://www.openerv.org and it is better than leaving the window open.
- not_kurt_godel 4y agoThat's not adequate, at least for me as a relatively average sized man in a relatively average sized living unit. My respiration is sufficient to raise CO2 levels indoors to over 800ppm from background levels within an hour without constant ventilation.
