Passive Heating Concept

Abstract

Passive heating is the term used to describe the energy, which is provided naturally by the sun, without any assistance from an artificial source. Solar heating energy is a radiant heat causes natural processes upon which all life depends. Some of the natural phenomenon can be managed through building design in a manner that helps in heating and cooling the building. The basic natural phenomenon’s that are used in passive solar heating energy are the thermal energy flows associated with radiation, conduction, and natural convection. When sunlight strike a building, the building materials can reflect, transmit, or absorb the solar radiation. Dark colors absorb extra sun energy that light colors do. Light interiors reflect more light and decrease lighting requirements. In addition, the heat produced by the sun causes air movement that can be expected in designed spaces. These basic responses to solar heat lead to design elements, material choices, and placements that can provide heating and cooling effects in a building.
