I had indirect light in a well lit up family room. That even created algea blooms. I had to keep the lights off more and shades pulled down to kill off some of the blooms. Maintenance also played a factor. Once I got that squared away I still had that bloom spike each spring. Here in Alaska we tend to get a tad more light in the summer months.
Meanwhile the tempature swing along would cook the tank I'm sure. I have a portable AC
(Yes in Alaska mind you) for my office in front of the hose (New tank location). I've only one window and it's closed with blinds drawn. Can't keep the tempature down in the room let alone by the window.
My two cents worth. If you do manage to place by the window, I'd have a back out plan just in case you need to move in a couple months.
