Most houses stay heated during the day anyway, remote work or not, it doesn't change the situation that much. And offices will remain heated whether there are full or only half of the employees actually in the building.
Do you turn off the heating in every room in your house when you go out to work?
Even if you did have some "smart" appliance that would make it easier, you'd have to "over-heat" when you come back to get again the desired temperature (or pre-heat a few hours before coming back), which would mostly make the effort's result insignificant...
It would make sense to drop heating when leaving for a few days though, week-ends/holidays. Offices are not heated on week-ends for example.
I will note that I am in a warm country, so we much more rarely have the heat on. But if I'm out of the house for 8 hours, I'll definitely turn off the AC. It might take time to get the house cold again, but c'mon, no way we'd pay for a day's worth of electricity for no reason.
I wonder how much this changes if it's heating vs cooling, and based on how much you have to heat/cool a place.
