Passive Solar Heating

Passive solar heating is one of many approaches in an assemblage of designs known as passive solar design. When appropriately united, these approaches can play an important role to the cooling, heating and day lighting of any domicile or building.   

Passive solar heating specifically utilizes a building’s ready elements to accumulate, keep and disseminate solar heat gains to minimize the need for space heating. Passive solar heating does not necessitate the utilization of automatic paraphernalia as the heat generated uses natural methods such as convection, conductance and radiation, plus, the thermal storage is located within the implement itself. Another benefit of passive solar heating stratagem is that it conveys day lighting opportunities and views to the outside via windows which are tactically placed.   

To get optimum results, passive solar heating should be integrated into a building or house during the preliminary design. Window design options, particularly varnished selections, are a pivotal element for concluding the success of passive solar heating. It is also important to know that passive solar heating does not cost as much as its active solar heating system counterpart, and the long term payback period is also greatly diminished.   

South facing windows are the preference for heating climates, as these windows are closest to receiving sunlight gains throughout the changing seasons. Passive solar heating systems do not need automated mechanisms to work. However, it may become more efficient through the use of blowers and fans to help the innate flow of thermal energy. Passive solar heating systems which are aided by motorized apparatus are called ‘hybrid’ heating systems.      

Passive solar heating systems employ fundamental theories which are integrated into a particular building’s architectural blueprint. These theories normally incorporate structures with rectangular floor plans, lengthened on an east-west alignment, a glassy south- facing barrier, a thermal storage medium bared to solar radiation which infiltrates the south facing glass, and windows or openings on the east and west barriers or walls. Usually, there are none located on the north walls.   

The most pivotal attribute of passive solar heating is that it is completely holistic; the system depends on the amalgamation of a structure’s style design, resources considerations, and motorized systems to diminish heating and cooling loads. Passive solar heating takes into count of local climate circumstances including temperature and wind and solar radiation to manufacture climate-receptive, energy preserving structures that can be driven with extended energy sources.     

There are several benefits of passive solar heating which comprise increased user comfort (appropriately designed domiciles and structures are bright and cheery) , elevated user productivity (the building becomes a wonderful place to work, houses a delight to live in) and diminished emissions (dependence on solar energy generates a renewable and non polluting energy source which does not emit greenhouse gases and greatly slows the depletion of fossil fuel).

In an archetypal setting, passive solar heating involves the accumulation of solar energy via specifically oriented south facing windows, the storage of energy in thermal mass, the expected dissemination of stored solar energy, and window stipulations to permit higher solar heat gain.
