Passive Solar Energy

The passive solar system means the interaction between solar radiation and buildings, not needing active components. When a fluid transfer and distribute solar heat in the building of solar is used the term active both active and passive solar are using infrared rays systems. Before the introduction of boilers and heat distribution systems such as radiators or aero terms, the primary form of control the climate inside the building was through “passive solar architecture.”Basic natural processes used in passive solar architecture are energy flux associated with thermal radiation, conduction and natural convection. When the sun shines a building, building materials can reflect, transmit or absorb solar radiation. In addition, heat causes air movement produced by the sun, which can be provided.

These responses have led to solar heat basic elements of design, selection and placement of materials, which can produce heating and cooling effects into the home. They can often be seen in old buildings and especially Southern Europe, where, for example, windows have exterior shutters that can be used to reduce summer sun heating and retain heat during passive solar in the winter. The architecture has the great advantage that it requires external energy sources and therefore referred to it as an operating cost and not contributes to environmental pollution. These aspects can improve the visual aspect of the building and will help to preserve it. The potential of a building depends on the length, orientation and type.

Basic characteristics of heating can be used to provide solar heating in winter. The easiest way is by absorbing sunlight through an outside wall, facing south which allow heat to be conducted to the inner wall of the house. To be effective, the walls should not be over shadowed by trees or buildings should not be in the shadow of light through nearby windows. Transmission allows infrared rays to heat the room air by convention. If the glass window exterior is covered with a suitable reflective layer on the inside, when infrared rays are reflected back into the room, thus it is retaining heat. The higher the building thermal inertia is, the more heat can be stored in day time reducing the need for heating during the night.

Trombe walls can be a solution. Trombe is the name of a French engineer who popularized this type of construction in the ’60s. A Trombe wall is a black or dark wall, using a glass located before the greenhouse it catches inches to form an air gap. Exterior wall is heated by the sun that warms the air in the front of the wall.
