Dictionary of Real Estate Terms: passive solar heating
passive solar heating
a system of features incorporated into a building's design to use and maximize the effects of the sun's natural heating capability.
Example: Passive solar heating systems use some type of collection and storage element, such as a water-filled partition, which is exposed to the sun during the day and radiates heat to the structure at night. Other features, such as south-facing windows, site orientation, roof overhangs, are included to enhance the effects of the sun's heat.
