Every homeowner and renter can make simple home improvements to increase the passive solar energy available and used in the home. Keeping in mind the five elements required for passive solar, consider the following.
The thermal mass in most homes is already in place and will not
change. This solar storage will be a floor or wall. The larger and more dense the mass, the more heat storage is available. You can also change the color to absorb more heat energy. For most homes, the aperture is in the form of windows or skylights, and the control will be some type of shade.
