I actually invested in automatic window shades! Cost me big bucks to do all my windows but it's worth it to me!
These things can sense the sunrise and sunset and will open and close automatically. They are wired directly to the AC power supply and have a DC battery backup in case the power goes off, in which case I have them programmed to open completely if the power fails.
As the sun rises and the heat starts coming in, the window shades will angle downward slightly to reflect the direct sun back outside but remain open just enough to keep the daylight itself coming in.
At sunset, a sensor opens the shades completely as the sun is going down, then as the sun disappears over the horizon, all the window shades in the entire house close simultaneously and stay that way until sunrise again!

@swirlie This is very important. The radiative losses/gains through windows are really significant. Whenever I see a huge amount of glass, I think about that.
Good for you!
