Solar Design Masonry Floors

Sunlight hits the surface and is absorbed as heat.

Solar design masonry floors. No sun no passive solar heat or any other sort of solar. 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. In a direct gain design sunlight enters the house through south facing windows and strikes masonry floors and or walls which absorb and store the solar heat. When sunlight strikes a building the building materials can reflect transmit or absorb the solar radiation.

The design standard for today s passive solar homes is between 7 and 12 of floor area in south glazing a 1000 square foot space would have between 70 and 120 square feet of solar glazing that means the transparent glass dimensions not the entire window unit which includes sash and frame. In addition the heat produced by the sun causes air movement that can be predictable in designed spaces. If you re building new look for a site that has good sun exposure from 9 a m. Shifting peak energy loads with concrete masonry construction tek 6 3.

Doe this article discusses the five key elements of passive solar design and links to additional passive solar design as well as solar design evaluation questions and answers. Passive solar building design is a strategy by which a building s windows walls and floors can be designed to collect store and distribute solar energy in the form of heat in the winter and vent solar heat in the summer. 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. National concrete masonry association 1991.

During the heating season 10 2 will do in a pinch but more is better. When looking for a heat storage solution that would allow us to incorporate solar air heating panels into our design in an engineered and reliable way we approached legalett a manufacturer of slab on grade insulating concrete form kits for problem soils and air heated radiant floors to see if high efficiency solar air panels could feed air. The air core system for thermal storage. National concrete masonry association 2006.

Marcel dekker and ases vol. As the room cools during the night the thermal mass releases heat into the house. The key to designing a passive solar building is. Passive solar design strategies tek 6 5a.

Elements of passive solar design to design a completely passive solar home you need to incorporate what are considered the five elements of passive solar design. This surface such as a masonry wall floor or partition sits in the direct path of sunlight. Five basic elements of passive solar design u s. This is called passive solar design because unlike active solar heating systems it does not involve the use of mechanical and electrical devices.

1 choose a site with good solar exposure. Passive solar techniques are applied most easily to new construction but existing buildings can be retrofitted to passively take advantage of the local climate. Or use a tile or masonry floor finish.
