Owner approach of sustainability

BSD Green Office Park was recognized for incorporating advanced green architectures to conserve energy, water and natural resources. All its buildings maximize sunlight penetration while reducing solar heat, thus boosting energy efficiency, and optimizing air circulation.

Architectural description

GOP 6 Building Orientation is located 22.5˚ to west/ east and active work room face to north or south, (two wings). The design was made to help reduce solar heat and thus energy consumption. West-facing elevation should be minimize and if necessary, adequate sun-shading is to be provided at these elevation The floor elevation has five floor It aims to supply enough sunshine which is through into active work room

If you had to do it again?

all system are going well as planed. further more it increases efficiency in operational building cost.

Building users opinion

building more healthy and comfort, increase productivity for occupant

Energy consumption

• Primary energy need : 140,00 kWhpe/m².year
• Primary energy need for standard building : 250,00 kWhpe/m².year

Calculation method :

• Final Energy : 117,00 kWhfe/m².year

Envelope performance

More information :

Wall of façade GOP 6 has an area about 5.624 m2. It had been designed and made from some layers of material for solid layer such as concrete, light brick ACP (aluminum composite panel) and gypsum for inside layers The glass uses 8mm T-Sunlux T-CS 140 #2 + 12mm AS + 6mm Panasap Dark Blue (Bluish Grey). Panasap Dark Blue (Bluish Grey). The Panasap glass can absorb radiation of sun which enters the building about 55% (U-Value Total Solid is 1.89 Watt/m2.K). and (U-Value Total Solid and include glazing/transparant is 2.96 Watt/m2.K)
(OTTV) is about 28.9 W/m2 and Roof (RTTV) is about 29.7 W/ m2. The value is better than National Standard by SNI 03-6389-2000 it is 35 W/m2

Use of non-potable water for cooling tower and other purposes it use recycles water and storm. The total of water needs is 62 m3 which supplied by 62% recycle water and 38% clean water.
Rainwater harvesting & percentage in reduction of potable water consumption: the water needs which can supply by the storm are 47m3. It is based on assumption that rainfall is 50 mm/day with the percentage of storm 53% in a year.
Water treatment / recycling capacity
The water needs which can supply by recycling water is 25.6 m3. It used to supply WC flushing, irrigation, and makeup
