I found an old newsletter of mine for architects (back from when I had hair!). This article deals with basic solar considerations for locating windows. In case the reprint is too blurry-the bottom line is this:
- Limit east and west facing glass (overhangs are not as effective for east/west glass).
- Put south facing glass as high on the wall, closer to the overhangs. Be picky about angles if you want winter passive cooling.
- Put as much north facing glass as you like.
- Put shading on the outside of the building instead of inside.
This is very basic information but it gets neglected more often than not.
When one has a small building or house, optimizing windows for the sun becomes even more important because small structures typically only get one thermostat and the sun can cause temperatures in small buildings to vary as much as 25 degrees from one side of the building to another.
