Can I hire you to figure out how to cool my space? It's only 625 sqft, and it's all one room except the bathroom, which accounts for the middle third of one side of the house (kitchen is on one side of it and bed area on the other, but they're not separated from the other half of the house by anything. The problem I have is that all my windows are narrow casement (crank out) windows, so the only AC I can use is a floor unit, with a plexi plug covering the rest of the window. They're too narrow for real window ACs. It's 14,000 BTU, ostensibly, and has a dual hose to avoid creating negative air pressure inside the house, but it can only really keep it 10-15° cooler inside than outside. That's fine until it's over 90°, which thankfully doesn't happen all that often. The AC has to be in the southeast corner, and there can only be one, because all the outlets near the windows are on the same circuit, and it's not able to power two. Oh, and the whole east wall is a giant double sliding glass door, which has a gorgeous view of the river, but gets hot first thing in the morning. I'm mostly kidding, but man, any suggestions for how to improve this would be great!

I had a similar issue in my old apartment. You might consider the use of a thermal battery. Cool the space at night (when it's cooler already) as much as possible. Then during the heat of the day, use thermal curtains to both block the heat out and to trap the cool in. On days where that is simply not enough, cross breeze is underrated. Get one of those magnetic mosquito door net things and set it up on your front door. Open the windows and the doors when it's too hot for the AC to help and get some air movement with a fan if necessary to push air from the shady side to the hot side.

  At least I know I'm on the right track. I've been doing all those things! Fortunately cross breeze often comes in off the river, which is cooler, and I'm far enough north that it doesn't break 100° more than once or twice a year, if that, so I guess maybe this is as good as it gets.
