Getting the sun’s energy into a building is easy, but making good use of it is both an art and a science. How can this heat energy best be retained in the home for use when you need it? One answer is to use structural insulated panels (SIPs) for some or all of your walls and ceilings.

Good passive solar design starts with a very efficient envelope, comprised of the floor, walls, roof, windows, and doors. Each component plays a distinct role in achieving heat retention. How these parts are incorporated into a solar building will be influenced by overall expense, aesthetics, interior and exterior finishes, and structural load requirements.
