Introduction
It may be possible to utilize a large amount of "free' energy, supplied by the Sun, which could power a number of devices. Controlled properly, energy from the Sun may reduce heating loads, decrease artificial lighting requirements and minimize cooling energy. However, the Sun also has the potential to hinder the energy performance of a building. Losses due to poor ventiation, inefficient materials and poor design may waste a large portion of energy. The data discussed below will aid in the decision making process regarding building retrofits and redesign.
