What is a passive solar building?
Passive solar building is a structure built using solar energy design techniques. This field of design uses natural thermal energy and light provided by the sun. In cold climatic zones, a passive solar building will be designed to maximize solar exposure for free, natural heating. In warmer climatic zones, passive solar buildings are designed to minimize heat gain from the sun to keep the temperatures inside a comfortable level. Passive solar design does not necessarily require solar panels or other active solar components. These buildings have large windows that are located to maximize solar exposure in a colder climate. The floors and walls of the building are often made of special materials such as concrete or brick that naturally absorb and store this solar heat. Once the sun decreases, this thermal energy emits home to ensure free heating.
in hot climatic zones is passive solarThe building is often oriented to minimize the solar exposition during the hottest parts of the day. This may include the use of special glazing windows or reflective roofing to maintain sunlight and heat outside the building. It also includes strategic use of landscaping and trees to provide cold shade and blocking sun rays. In hot and cold climatic zones, effective insulation and techniques of weathering play a major role in the success of passive solar design.
Passive solar building may also include functions such as solar water heaters or solar cookers. Passive sun water heating uses special tanks or pipes installed along the roof to use thermal energy from the Sun. Water then flows to sinks, showers and other home accessories. Solar cookers resemble small boxes lined with solar panels. Panels absorb solar EnerGII to the natural temperature inside without the use of electricity.
natural lighting also plays an important role in passive solar design. Windows and skylights are used to allow light to the house and reduce the need for electric lighting. During the afternoon, blinds may be added to prevent the sun to reduce solar heat gain.
The passive solar building offers many advantages to passengers and owners. These structures require smaller heating and cooling systems than traditional structures, and some may not require any furnace at all. By reducing the need for electricity and fossil fuels, passive solar design allows homeowners to maximize energy efficiency and maintain low costs. Effective design of the building helps to protect the environment by reducing pollution and maintaining limited resources.
