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.

Rubber Plant (Ficus robusta),

Peace Lily (Spathiphyllum clevelandii),

Boston Fern (Nephrolepis exaltata ),

Red Emerald Philodendron (Philodendron erubescens ),

Gerbera Daisy (Gerbera jamesonii ),

Areca Palm (Chrgsalido carpus lutesers).

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

15


2.3 Buffer zone :

• Typical Floor Plan

16


2.4 Shading :

• The canopy in front of the main entrance • The aluminium shading

17

2. The building was properly oriented in order to maximize natural daylight but minimize the heat gained by: 2.5 The use of insulating material :

Curtain wall (insulating laminated glass)
