Effect of Educational Building's Direction on Cooling and Heating Loads in Different Regions

Introduction and Due to energy resources limitations it is necessary to optimize design of buildings in point of saving energy. For this purpose, suitable direction of buildings is so important because of reducing of heating, cooling load and wasting energy in buildings. The goal of this research is the effect of direction in quantity of heating & cooling load in educational buildings.Method and For this purpose it's taken a sample school with the same physical & geometrical condition in variant microclimate. Then we use Carrier software for modeling of the building and consider direction effect by rotation of building in 22.5 degree and calculate heating and cooling loads.With comparison of revealed results, appropriate orientation of the buildings with regards to thermal and cooling loads and proper orientation from point of annual energy saving of the buildings in different regions of Iran is recommended.
