G Tower is the latest in green buildings, incorporating features like massive green walls and refreshing rooftop gardens, located at the crossroads of two major thoroughfares in downtown Kuala Lumpur, Malaysia. This sustainable building received the Green Mark Gold Award from the Building and Construction Authority of Singapore. It has also taken up the position of being Malaysia’s first carbon positive building.

The building rings in a new concept by combining offices, a private club and a boutique hotel, all under one roof. The boutique hotel, named G City Club Hotel offers 180 executive rooms, conference rooms, function/board rooms and an infinity pool. The orientation of the building with the sun is very appropriate, and several water-efficient features have been incorporated.

Green Features

1. This tower uses 25 percent less energy as compared to other buildings of similar size and location, thanks to efficient air-conditioning and lighting systems.
2. Double glazed glass panels with vacuum in between have been used, which helps cut heat transmission.
3. The extensive landscaping with sky gardens, ponds and green walls help cool the overall environment and improve air quality.
4. The swimming pool is kept clean through the use of eco-friendly cleansing salt rather than chemicals.
5. A sophisticated rain water harvesting system irrigates the plants and vertical greens found throughout the building. Condensed water from the cooling tower is collected for re-use. 
6. Hot water is generated using waste heat from the air-conditioning system.
7. The carpets and external timber decking use green certified recyclable materials.
8. The interior décor includes refurbished furniture.
9. Toxic free building materials, paints and wallpapers are used for their low volatile organic content (VOC).
10. Motion-sensitive lighting helps bring down power costs.

G tower saves nearly 7.3 million Kwh of electricity per year, at a ten-hour day, 6 day-week and 52-week year activity period. This is equivalent to a reduction of 3.5 million kgs carbon dioxide emission into the environment, which is same as saving 18000 trees per year.
