go solar - long cold climate house
In a climate with cold winters and moderate summers, houses that are long and thin on their east-west axis are best because they expose more wall surface to the south, where it will be warmed by the sun in winter.

go solar - shade vines
Flowering vines above the patio of this California home are just getting started in the spring. By summer, their rapid growth transforms this area into a cool, shady spot. In winter, the vines die back and allow more of the sun’s heat in through the windows.
