Solar modeling helped us determine the size and angle of the large roof overhangs to shade the west-facing clerestory windows. We wanted to keep the extensions at the same upward angle of the roof (instead of angling down) to provide views up the hill from within the house through the clerestory windows. The overhangs shade the clerestory windows throughout the afternoon until the adjacent hill to the west takes over after 4pm. Image: Sergio Bravo
