We simply didn’t need those things. Cold winters were more of an issue than hot summers, so our homes historically have been built with brick or stone construction that holds the warmth.
When it is hot for just a few days in a row, that same construction actually helps stay cool, because even if it’s hot outside the heat takes a long time to penetrate, and inside stays nice and cool.
But now that climate is changing and we’re seeing summers with a couple of weeks of intensely hot weather in a row with temperatures higher than ever, that same construction actually becomes a problem. Because now the stone and brick become completely saturated with heat, and even at night when it’s cooler outside the brick is staying hot and radiating that heat. It’s basically like living in a pizza oven.
The past few years it’s been like that maybe only a couple weeks of the year, but nonetheless air conditioners are starting to become more popular.
For insect screens, same deal - we just never usually have a problematic amount of insects. Which is why when we do have a lot of insects it’s in the news.
Yes, thermal mass only serves to even out fluctuations in temperature. If the outside environment swings between hot and cold then a building with high thermal mass will tend to have a temperature in the middle of those two extremes. Like how a heavier ship is tossed about on the waves much less than a small boat.
But if a place is consistently hot or cold for a long time thermal mass doesn’t really do anything. At most you can use it as a battery, so you can, for example, run a heat pump while electricity is the cheapest and use the thermal mass to maintain the temperature you established over the costly period.
So many people think that its a substitute for insulation though, which slows down the rate of heat transfer in or out, and does actually let you use less energy to maintain a given temperature.
