I recently picked up a book about a solar house in Martha's Vinyard on what was Solviva Farm. The house was Passivley solar heated. Even in zero degree weather the house stayed a warm 70 more or less with it's green house style and water walls to retain heat.
We never get that cold in Washington but heating is important. At 612 N Forest we hardly turned on the heat to save heating bills. This turned dangerous not because it was to cold, which it was, but because the moisture never left and we ended up with black mold everywhere. We keep the heat up in our apprtment now and the bathroom fan on. What a waste of energy:(. But we don't get as sick and the apartment has never smelld of mold:). It is heathy to have a watm place to live. So we have a small but meaningfull dilemma. In the move to energy independence I need to find ways to use solar heat to heat water and heat houses. This is actually a vary old forgitten idea....
