1. Create the green and cool environment around the building for the benefit of cooling down the temperature by.
oUtilizing the landscape can help reduce the ambient temperature by 3-5 c.

1. Create the green and cool environment around the building for the benefit of cooling down the temperature by.Some of the trees and shrubs are pollution-absorbing.

2. The building was properly oriented in order to maximize natural daylight but minimize the heat gained by:
2.1 Orientation :
• Shading of the back side • Shading of the front side • Locate the building in the proper direction
2.2 Select the shape of the building
