These pictures are of the 2007 Michigan Energy Fair show house being built. They show how the overhang's were designed to work with the sun's angles to cool the home in the summer (see the shadow lines just below the window openings). And in the winter the sun's angle changes so the windows get full sun light to warm the home, they call this Passive Solar Design. The show house was designed to be elongated on an east-west axis and so the south faces sunlight between the hours of 9:00 A.M. and 3:00 P.M. (sun time) during the heating season. And in the winter the South facing glass lets sun light in and allows thermal mass to absorb, store, and distribute heat. For thermal mass we have included in the design a two-sided fireplace that will be built out of stone or concrete tiles.
