Is 20°C supposed to be austere? Is that a typo? I keep my American home at 67-68°F in the winter...

20C in wintertime is quite cool for North America, in my opinion. I think 23C is commonly considered "comfortable," but obviously that will vary significantly by individual.

Chicago building codes require 68F as a minimum for residential in winter conditions, so I think that's reasonable as a "habitable minimum yet not necessarily ideal" benchmark: https://www.chicago.gov/city/en/depts/bldgs/supp_info/chicag...

Wow. Obviously there are humidity differences during different seasons, but 23°C is probably the limit of "this is uncomfortably warm" for me if I set my thermostat above that.

		Me too, but my husband and guests are clearly uncomfortably cold at my preferred 66/67, and my sister with poor circulation just about has her hands go numb.

		And to what temperature do you set your AC in the summer?
