carpe momentum

since my wife and I had to move our bedroom into the basement unexpectedly there has been a good deal of discontent with the situation. She detests the fact that only one window of around 3 square feet is the only source of natural light we have. I must admit that I would rather be up on the ground floor too. So it is either move to a new house or expand. Backyard is out, we have sunk too much money into the deck, pond, etc. Not enough room on either side yard, too narrow. That leaves the front yard. The front of the house is oriented south. For all the people familiar with solar energy this is the money side so to speak. She agreed to solar panels as part of the project, but dare I sneak an attached greenhouse in there? According to many passive solar sources such as this there could be some cost benefit in terms of heating and cooling savings.

And I could grow food in the winter :D
