this is exactly why I love talking about historical passive heating and cooling techniques
oh wow the glass-tower office buildings we constructed when we thought air conditioning and central heating would never have downsides...have downsides?
and we're still building them?
while the Victorian house museum where I work, with thick walls and small windows and big wooden shutters stays ~10 degrees above (winter) or below (summer) the outside temperature for days on end with no help at all?
(also public transit. the history of public transit in the US is infuriating, because we had it! and then we destroyed it!)
