Passive Solar Design

Passive solar design is one of the most important strategies for replace conventional fossil fuels and reduce pollution environment in the construction sector. Solar energy can be a great contribution to the heating requirements of a building. Depending on the weather and local predominant need be heated or cooled; there are wide range passive techniques. The aim is to rehabilitate the buildings to be more energy efficient and offer the highest standards of comfort visual, thermal and health for the occupants. The buildings that try to cover their energy needs using appropriate construction features and average isolation are called "passive solar buildings."

These systems can be used for heating, cooling and lighting. Its main function is to reduce the power supply. This is achieved through designs where the building and its solar system are closely linked; the architects play a role in its development.

For small buildings, environmental control can be achieved through small simple devices placed directly in heating or cooling acting on temperature levels. However, for buildings complex and larger economies of scale can be gained using special software located in the central processor of the control system building. This leads to the concept of Energy Management Systems Building (SGEE); the term management refers to the ability that gives the building operator to ensure efficient operation of the system. At the simplest level, this can ensure that for example all the light is off when the building is unoccupied (Gordon, 2010).

Costs

Costs must be able to increase between 5 and 10% on the price of a conventional construction. This slight increase is due to the characteristics improve passive solar gains such as insulating glass, the mass thermal, eaves and overhangs for sun protection and other shading systems, require greater investment to be able to be repaid with energy savings medium term. However, passive solar systems have proven highly efficient. Results show that recent monitoring buildings successfully used these systems need only a fraction of the energy used in similar conventional buildings. Due to the high degree of integration with the building, the cost of construction of these buildings can become be very little higher than in buildings without these systems. Also provide an additional value in the form of bright spaces or greenhouses. Solar designs liabilities are translated into comfort and energy savings simultaneously. Bioclimatic architecture may change little or a lot of construction conventional. Many possibilities are very profitable because of the great savings Potential energy bills.

Bioclimatic architecture uses passive design with care space, orientation, building sitting, sizing windows and material selection. All these pose little additional cost. Operating expenses increased by using special materials such as glass specialized carpentry with thermal response, fireclay, tubes water storage, mobile isolation, etc. In many cases, the costs are high because demand is low. Costs could be reduced were to a mass production (Criswell, 2006).

Costs also increase if you use expensive tiles or bricks used for soils with high thermal inertia, integration with the ground or ...
