Passive Solar Heating System

Typically the aperture s should face within 30 of true south and should not be shaded by other buildings or trees from 9 a m.

Passive solar heating system.

In addition the heat produced by the sun causes air movement that can be predictable in designed spaces. Instead they take advantage of natural heat flow to distribute warmth. Passive solar buildings take advantage of how the sun moves throughout the day with attention to seasonal changes in sunlight to warm living spaces without requiring any mechanical devices or fuel to do so. In passive solar building design windows walls and floors are made to collect store reflect and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.

Passive systems do not use mechanical devices such as fans blowers or pumps to distribute solar heat from a collector. Each day during the heating season. Passive solar design refers to the use of the sun s energy for the heating and cooling of living spaces by exposure to the sun. This is called passive solar design because unlike active solar heating systems it does not involve the use of mechanical and electrical devices.

These basic responses to solar heat lead to design. Because of the small heating loads of modern homes it is very important to avoid oversizing south facing. Passive solar heating is using the sun s rays to heat a living space by exposing the area to sunlight. The key to designing a passive solar building is.

When sunlight strikes a building the building materials can reflect transmit or absorb the solar radiation. Passive solar design takes advantage of a building s site climate and materials to minimize energy use.
