Technology for a Solar-Punk future.
Airships and hydroponic farms...
I'm not sure this counts, but the best upgrade I ever made for my home was having new windows installed 20 years ago. I couldn't open the old ones.
During the summer, most days I can avoid air conditioning just by opening the windows and getting a cross breeze. I hear my neighbors' airco turning on, while I am smug with the knowledge that I made a long-term frugal and green investment.
I'm so jealous :( we just got new windows to improve the insulation rating. I'd love to open them and do the same but I legit start having medical issues over 73° which we hit most days in the summer.
I'm so sorry you have that problem. The window insulation should still help, though.
