The Darwin house was built back in 1992, and its design was built entirely with air conditioning in mind. There are only two windows facing south (one in a bathroom) and two facing north (again, one in a bathroom). This is unfortunate, given that many of the better breezes come out of the south. Few rooms have windows in more than one wall, and those that do are not well aligned for cross breeze.
This would be all very well if, like our neighbors, we were happily closed up running the AC constantly. However, the AC unit died of a sudden electrical malady on Friday night, and since all good air conditioning techs are currently off enjoying the weekend with their families, we are engaged in a living history experiment to understand why it is that the major population shift south in the US did not begin until 15-20 years ago, perhaps not so coincidentally when it became possible to assume that any house would have powerful and effective central AC.
I'm not off-grid enough in my ambitions to necessarily want a house with no AC, but I would certainly prefer one that does not become a simmering deathtrap when the condenser ceases to hum. (MrsDarwin notes with indignation that she only just had it serviced last week.)
