Solar Building

Passive solar building usas solar energy for its energy needs in different season. The concept of passive solar building , performance and benefits are discussed.

Concept of a Solar Building 

The rate of increasing  population groth with increasing innovations in the field of industries and technologies have all together results in the increasing energy consumption normally. This high consumption is a concern for sustanability. This has a negetive impact on the enviromental and energy consumptions. So, an innovation in building construction that would perform with the existing energy, withoutexploting any additional mechanicalk and electical energy sources is called as solar building. design concept. These bulking take the advantage of the climates where it must be constructed. A proper site analysis would judge the performance of the building. The concept of solar bulding is adopted in new building But already existing building can be behave passively. The building is named  solar building because we dont make use of any mechanical or electrical device with in the bulding to bring the concepts.

Concept of solar building works base don the following principles:

• The first principle base don the route of the sun in different season. The sun is winter travellingf in a lower based route compared to summer time.
• Proper insulation enable warmth in winter and coolless in summer.
• The direct sun can be resisted by the over hanging elements.
• The location of thermal mass in a positions enabilling with absoption of solar energy would helps in the easy release of the same during evening time.
• In winter the south direction faced glasses will help in energy absorption and storage in the building

Elements consider for solar building construction:

• Room type, internal doors, wall and furniture in building and their placements.
• Building dismension extension in east west direction.
• The equator faced oriantation for the building.
• Use of thermal mass like floor and wall.
• Windows in the west are avoided.
• Window sized fixed to get adequete in solar in winter and shade of summer.

Performance of Solar Building

• The site climatic conditions.
• The solar building design criteria.
• The building size.
• The passive solar building is adopted.

Benefits of passive Solar Building

• The interior of the building would be filled with sufficient light. This is due to the transmission of visible lights frequencies.
• The directultraviolet rays are harmful. The passive solar building Has the advantages of blocking almost 99.99%of the ultra violet radiation energy.
• Summer is made cooler and comfortable , it keep the interior cool during the hot season .
• Winner made warmer.

Problems Faced by Solar Building

In hot climateds building with large glass area can overheat. Be sure the minimize east and west facing window and size shade device properly . For large building With high internal heat gain, solar heat gain is a liability because it increase cooling cost more than the amount saved in spaced heating.
