Standing in the living room as it transitions to the kitchen and looking south out towards the driveway. All the blank spaces in the exterior wall are rough outs for floor to ceiling wood and glass panels. This is part of the passive solar design of the house. The very extended eves (look at the black plastic wrapped laminated beams extending past the house footprint) were calculated with the latitude of the house and the orientation of the footprint. On the Winter Solstice, at 2 pm, the sun should be able to shine fully on the entire floor of the living room, generating the maximum solar gain. On the Summer Solstice, at 2 pm, the sun should barely be able to shine on the floor – minimizing the solar gain.
