Passive sun heating utilizes the the sun’s rays to control the temperature of the house warmth during the cold days and coolness during hot ones. As compared to dynamic solar heating that needs fans, air conditioners and such machines to control house temperature, passive sun heating employs only elements incorporated into the house design. In Orlando cooling the house rooms can be heavy on air conditioners, so that the passive solar design can lower the electricity load somewhat. On the other hand, in Orlando heating the house is not always needed even in the cold season.

In essence, passive solar heating is made by allowing the sun to warm up a selected space within or outside the house proper, and then making this heated air go in to warm the house interior. This is generally performed via airduct openings which can be worked to close or open based on the needs, admitting in air via the convection process. To cool the house, the sun is foiled from warming the room and any heated air is vented outside to allow cooler air to move in.

Most times, the area where the air is heated before moving it within the house is called the sun room. It is an enclosed space with stone or concrete floor, metal wall frame colored black or dark colors and glass roof and sides. The dark color, floor and glass are all intended to allow in the rays and soak in the heat they bring. When enough air is heated, the convection opening of the building at the upper side of the sun room is opened to bring the heated air into the house, while allowing new air to enter the sun room via openings near the floor.

When cooling instead of warmth is desired, the sun room is blocked to the rays by drawing in insulated boards right below the roof. By drawing in the blind, a passage is made between the boards and the roof where the heated can flow on its way out, through a port at the topmost part of the roof. In this manner the interior of the sun room is not heated, and instead is filled with cool air flowing from below and allowed to flow also into the house. The system translates to less expenditures on electricity used in operating the air conditioner or the radiator.

Passive solar heating is best included into the house construction, albeit it may also be as stated above an adjunct if space allows. Except for space and costs advantages or limitations, one form is as good as the other. It simply depends on the house members and the configurations of the yard space and the building itself, and styles can be made to include them into the considerations. What is essential is that the concept is utilized for the good of the residents and Mother Nature via diminished use of fossil fuel in making and consuming electricity and other non-renewable energy sources. Why not sample it? It can be of surprisingly great boon.
