Anyone have experience with reducing the energy lost through single pane windows? I'm in the final stages of buying a house, and it's got a wall of glass which is all single pane. I'm afraid that when summer rolls around, these windows are going to do a poor job of insulating us from the summer sun and drive my energy bill up...

Does anyone have experience in reducing the energy lost through these windows, short of replacing the glass? I've seen some interior storm window inserts which may work, but figured I'd ask if anyone actually has any experience.

Here's the wall in question:



Thanks!
