The concept is to minimise waste at every stage of construction

KOCHI: The `Green Building' concept is gaining importance in various countries, including India. These are buildings that ensure that waste is minimised at every stage during the construction and operation of the building, resulting in low costs, according to experts in the technology.

The techniques associated with the `Green Building' include measures to prevent erosion of soil, rainwater harvesting, preparation of landscapes to reduce heat, reduction in usage of potable water, recycling of waste water and use of world class energy efficient practices. The CII- Sohrabji Green Business Centre in Hyderabad had already proved its worth in terms of sustainable development, said S.C.Kumar and Prasad Jadhav, who had been closely associated with the project. They were speaking at a seminar organised here.

The concept encompasses the use of resources to meet the needs without depriving the resources for future generations, said Mr.Kumar, who is the senior adviser of the business centre. The Green Business Centre is a unique and successful model of public-private partnership between the Government of Andhra Pradesh, Godrej & Boyce Manufacturing Company and the Confederation of Indian Industry (CII), with the technical support of USAID.

The building has been awarded the prestigious `Platinum rating' under the LEED (Leadership in Energy and Environmental Design) programme of the U.S. Green Building Council. It has been rated based on the features of water efficiency, sustainable site, energy efficiency, indoor environmental quality, materials and resources.

The entire waste water in the building is treated biologically through a process called the `root zone treatment system' and is used for irrigation purposes. There is 35 per cent reduction in potable water use in the `Green Building' vis-à-vis a normal building, according to Mr. Jadhav. This is achieved by low water fixtures, use of storm water and recycled water.

The building site is regarded as a sustainable one. Extensive erosion and sedimentation control measures have been adopted to prevent erosion. Rainwater harvesting is another measure successfully executed at the building site.

Technology for real time monitoring of energy consumption helps to save energy. There is 50 per cent savings in overall energy consumption in comparison to a normal building, Mr. Jadhav said.

About 20 per cent of the energy requirement is met by solar energy.

The materials used for the buildings are either recycled or recyclable.

The materials include fly ash based bricks and recycled wood.

A considerable portion of the construction waste has been recycled within the building.

The Green Business Centre offers feasibility study for new projects. It also provides training in various aspects connected with the construction and maintenance.
