I think the builders of the past would be amazed by modern technology like argon filled double paned windows with advanced window films to reflect the heat instead of letting it in.

But yes, let's bring back the awnings too. Sometimes the low tech ways are easiest and best. I will say that I don't think awnings alone can save a stick built modern house from the heat. Part of the key to old houses staying cool was high thermal mass: lots of brick and stone that could stay cool during the day. As great as modern insulation is at keeping hot and cool separate, a modern insulated wall doesn't cool it's surroundings like a high thermal mass wall would.

Moving to a world where we combine passive cooling and high thermal mass construction with the benefits of modern tech will be key in my opinion.

While modern building materials are very good at keeping the heat out, they aren't perfect. My house was built without awnings or AC and with modern window tech, but we opted to have awnings and screens installed nevertheless and they made a huge difference in how much heat from sun is coming into the house (not to mention the bright light itself).

For my case, I think it's irresponsible to be installing AC without first making sure the house is optimized for keeping the heat out.
