The south elevation alternates view windows with Trombe walls. Overhangs protect from the hot summer sun but allow the low winter sun to be absorbed in the mass walls behind the glass.

Construction photo of the same view showing the concrete block Tromb`e walls. These are 8" thick, and will have glass two inches in front of them. The glass allows the sun's infra-red heating rays through to be absorbed by the walls (they are painted black). The walls store the heat, and at night give back the heat slowly into the 2" space between the glass and the wall, where it rises and is let into the house. The rising heated air draws in cooler air from the house interior (its ducted through the slab floor ..see the holes at the bottom of the walls). The wall second from the left is the back of the Living Room fireplace.
