Solar architecture is architecture that incorporates features to take advantage of passive solar energy, daylighting, and/or active solar energy. Some methods of solar architecture date back thousands of years. Others make use of the most advanced technology, involving solar collectors and solar moduless, together with passive building elements such as selective surface coatings and Trombe walls. Depending on circumstances and location, the goal of solar architecrure may be to achieve zero-energy, low-energy, or plus-energy buildings.
