Indian Green Building Council: Green Building Demystified

11 May

The word “Green” building although heard by almost all people within the Construction & Building Industry, not all understand what it means and what the word LEED & GRIHA certification signifies.
To make this easy to understand one has to understand certain basic facts of Environmental degradation and the advancement of civilization. The reasons for Environmental degradation are many in an industrialized nation and primary among them is the Building Industry. It alone is responsible for 40% of energy related Green House Gas emission and 60% waste come from the building industry.

One must bear in mind that the building industry is the largest consumer of all other sectors of the industrialized world, it consumes steel, cement, sand at the basic level and wood, aluminum, glass, textile, leather, paint etcetera and the finishing level. What is most striking is that almost all materials used in a modern building is mined, extracted or harvested for the Earth natural resources. This natural resource in its pristine form usually has a GREEN cover, there is usually a lush green forest or meadow full of beautiful green grass & flowers swaying in the cool breeze before the Bulldozer comes in and rips it apart to extract – iron ore, or axes chop down the trees and huge hydro-power dams flood the region and the beautiful scenic valley is under water, never to be seen again. So we destroy this green.

Why does it happen? Simple! We need the materials to build ourselves a home. So every-time we buy or sell a home we are responsible for the degradation of the planet. While no one can advocate that we must then go back to living in caves, taking a little responsibility would help a long way in preserving this planets natural resources for the future generations and give them a healthy Environment to live in. Therefore when buildings are designed sustainably and are energy-efficient, they consume less electrical power and less water, it also reduces by almost 20% the use of building material & waste. In this process it saves more materials from being extracted and thus helps in preserving the “green”. Therefore sustainable and energy-efficient buildings are called “Green” buildings.

The environmental movement might be said to have begun centuries ago as a response to industrialization. As universal concern about the healthy and sustainable use of the planet and its resources continued to grow, the UN, in 1972, convened the United Nations Conference on the Human Environment, in Stockholm.

While many laws have been passed over a time for industrial pollution, vehicular pollution etcetera, it was soon recognized that the construction activity also needs to have its act cleaned up. The United Kingdom came up with a sustainable building rating system called BREEAM, the United States of America created the LEED and recently India has its own National rating for buildings known as GRIHA.

In 2001 the Confederation of Indian Industries {CII} under the great foresight of Godrej brought in LEED { Leadership in Energy and Environment Design } to India and it was called LEED -India Green Building rating system. With time, great Indian minds of the business & industry came together to fashion the Indian Green Building Council (IGBC) which today has many building rated all over India under its certification.

The Government of India too under its National Action Plan for Climate Change, understood the need for an indigenous sustainable building rating system, as not all type of buildings especially in the smaller towns and cities of India, where need & life style are different from in the bigger metropolis, could be rated properly under the LEED rating system which is based on foreign climate & life-style and the IGBC is still evolving. This rating system is called Green Rating for Integrated Habitat Assessment (GRIHA).

Today in India the awareness in Green Building is increasing day by day, with the tireless efforts of the councilors of IGBC and GRIHA. Many young architectural and other engineering students today are applying for the examination to become LEED / IGBC -AP and GRIHA – Trainer & Evaluator. As the Climate change awareness increases its domain to all sectors of industry, this added knowledge shall put the future managers in good steed.
