Not many U.S. cities have a subway. I think the only substantial subway system is in NYC. The city I live in has a very short commuter rail line that doesn’t go to/from anywhere people want to go. Buses are gridlocked in traffic like everyone else, and have to make frequent stops, so it can take something like 2 hours to travel 10 miles. The low-wage workers I know without vehicles just spend $40/day on Uber to commute to work and back (which is a significant percentage of their pay).
I think shutters (preferably white) would probably help on south and west facing windows. I don’t really see them used much down here; the ones I do see are fake. Highly reflective silver tint (applied on the outside) helps more than dark tint. Window awnings would also help. Large trees are the long-term solution :)
