Optimization building orientation and windows by using solar radiant energy

The buildings are the largest consumers of energy in all countries. Especially in areas with bad air and water conditions, the main part of the energy go to the heating and cooling of buildings. Although there are many ways in reducing the heat load on buildings there. The most important of them the detailed design and choose the appropriate cover and construction elements. In this study, with a 71.5 m2 area modeling located in Iran, Sari town, in the software Carrier Hap 4.5. Maximum thermal efficiency radiant energy of the Sun for 12 months a year in a sixteen-Division-directional, can be calculated. Operating on the basis of the lowest rate of solar energy in the hot months, and the maximum amount in the cold months, building facades stretch, in the direction of the South without any deviation to the East or West, it is recommended. On the other hand, the amount of heat transfer materials, walls, and the incoming radiant energy into space through Windows is calculated. According to the ratio of the radiant energy input rate of Windows, heat transfer rate of the walls and materials, And considering this important factor, which is not manageable after the construction of the wall, But after the windows construction, as well as the ability to control their performance, The window can be used as an important factor in controlling the environmental conditions and comfort in the building.
