Building Orientation

Homes with proportionately more south walls are easier to heat with passive solar. More available wall and window area facing the sun equals more heat for a passive solar home design.

Cooling this home seems at first to be more difficult because of the greater southern exposure. This, however, is not the case. Properly sized overhangs shade the south wall in the summer due to the high sun angle at midday.

Homes elongated on the east-west axis will have a natural advantage to heat and cool more efficiently.
