alt Hacker NewsWearing jacket indoors is not a problem if your building is built like that.
I live in well insulated house. Big problem is moisture management if I don’t keep indoors fairly warm I will get walls wet especially in bathroom.
Heating up just bathroom is hard as outside is well insulated but then internal air flow cannot be blocked.
It is also not that great in the summer when it is hot outside. Cooking or any bigger screen will heat up inside of the house. But then opening windows might not help when it is high heat.

Heat recovery ventilators are one possible solution. You can hook them up to home assistant humidity sensors and open a vent for example.
I got a CO2 monitor, and noticed that it often went over 1000 ppm CO2. So I started cracking the windows slightly, which resolved it. There are downsides to sealing the house too tight.
An electric dehumidifier in winter keeps moisture in check and you get the energy of evaporation back as heat.
We solved our humid air in the bathroom with an active extraction fan that starts when it registers humidity and light (I think) in the room.
You can use dehumidifiers at a fraction of the power cost of full air heating, given that you only need to keep the surface pores of the e.g. wallpaper below a humidity that supports mold growth. Similarly, the bathroom could gain a second insulated door-ish curtain for an airlock effect fairly easily.
