No 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.

Do 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

I mean efficient in terms of heating/energy, not CO2 levels.

I got the window unit version of https://www.openerv.org and it is better than leaving the window open.
