Hello everyone. This is my first post here. Someone from your forum invited me to come check it out. Right now I'm in the process of designing a home as green and simple as I know how. So far, I'm still on the drawing it on paper stage. Today my task is overhangs. I drew a little template of the high summer sun angle for my area and in order to keep the sun from entering the house at all, the overhang on the South side at a little over 2.5 feet Most things I've read show the same drawing of the summer sun high angle and keeping it out of the house. My BF is wondering why you would want to keep all of the high sun out? If the sun came in a foot would that really overheat the house that much? Also, during the summer some sun is going to come into the house before and after the high angle so why all the effort to keep out all of the high angle? I think he just doesn't like such a big over-hang. The primary entrance is on the East side and protected. Any input? I look forward to checking out more of this site.
