Hyderabad is leading by example with many residential houses and apartments adopting the technology.

Green Building

Hyderabad : Are you planning to construct a new house for your family? Then you are right at the mecca of green buildings i.e. Hyderabad, which in the recent past has become well known for the concept of green building.

The Capital has made a lot of headway in pushing green buildings with many residential houses and apartments adopting the technology. Essentially, the entire concept of green buildings is based on less consumption of energy and generating fewer greenhouse gases than the average.

CII-Sohrabji Godrej Green Business Centre in Hyderabad is the first Platinum rated green building outside of US and was constructed way back in 2004-05.

Energy efficient

Green buildings are energy efficient than the normal concrete buildings and the energy consumption of such buildings is 40 to 50 per cent less than the traditional concrete structures. Usually, such buildings are equipped with energy efficient lighting systems that include LEDs and CFLs, which also provide better lighting than the traditional ones. Such buildings also use autoclaved aerated concrete (AAC) blocks for facades, which reduce 15 to 20 per cent load on air conditioning (AC).

Green buildings also have double glazed glass units with argon gas filling between the glass planes, which means heat and cold, are less likely to enter into homes during summers and winters, which reduces power bills and also greenhouse gases.

Moreover, glass allows better lighting in the day and provides good ventilation for landscape gardens. Close to 20 per cent of the energy requirements of Green buildings are catered by the solar photovoltaic, which is more efficient in producing supply of energy.

Water efficiency

The Green building of Godrej-CII in Hyderabad has built rain water harvesting system, which enables them to store 100 per cent of rain water in a tank, without any drop getting wasted. Water consumption in the green buildings is 30 to 40 per cent less than normal buildings. The treated and recycled water is used for landscaping. Water efficient faucets regulate water up to 50 per cent, beneficial in the water scarcity places.

Health Factor

In addition to water and energy consumption, the green buildings also have a profound positive impact on health of the employees. Natural air from the green roof garden and less energy consumption bulbs release less heat into the office space.

In CII Godrej building, low volatile organic compound (VOC) paints were used that prevents the smell of the paints. Green buildings usually are efficient in implementing the basic practices of waste segregation that involves separating plastic waste, paper waste, food waste and converting them into compost and manure for the gardening.

“Green buildings cost 2 to 3 per cent expensive than the normal concrete houses. However, such concepts are highly energy efficient and within two years of time, all the costs that have been incurred will be equal to that of normal houses,” says S Raghupathy, Deputy Director General, CII Sohrabji Godrej Green business centre.
