I really like this design.. it can be deployed at a moment's notice, and brought back in without even trying.

A nice thing about natural convection is that there is a purpose to leaving storm windows installed on the sunny side during the summer. Instead of opening your windows to let air in when it's hot indoors, open the window only a little bit, then go outside and open the upper section of the storm window just a few inches. The natural convection will draw the warm air out of your house, and you can open a shaded window to draw cooler air back in!
