2. The Government of West Bengal is to be lauded for its path breaking initiative to allow extra Floor Area Ratio for Green Building in order to provide incentive for adoption of green norms for all upcoming residential and commercial building.
The question arises
‘What is a green building’
How can it be assessed and quantified.
How can it be incentivised effectively?

3. What is a Green Building ?
A green building is one that uses less water, optimizes energy efficiency, conservative natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building

4. Sustainable building has always been a way of life in India.
Traditionally, in India, we have always built edifices using locally available materials with great skill, in harmony with nature and the local climate.
The Indian way of life is aparigraha (minimum possession), conservation (minimum consumption) and recycling (minimum waste). These three attributes are the guiding principles for sustainable buildings as well. With these attributes and its rich heritage, India can make a substantial contribution in this field and eventually lead the world on the path of sustainability.

13. Less than hundred years ago, industrial revolution came to India and changed many of these traditional sustainable practices in buildings. The insatiable thirst for progress and comfort-at-any-cost, altered the equation with nature for ever, Concrete, steel, glass and later plastics became the dominant construction materials, beyond stone and wood of yesteryears. Power supply, artificial lighting, water supply and disposal, and thermal environmental control within built environment, were desired and obtained.
The older civilizations grew along the river banks, always regarding rivers as sacred. With the industrial revolution, untreated water, effluents from chemical industries and organic waste were discharged into rivers and water bodies, destroying our precious sources of water for domestic use. In addition, the unsustainable development of building and industries have led to huge construction waste and solid waste during their operation, which today have become a major problem.

14. Modern building in India consume about 25 to 30 percent of total energy, and upto 30 percent of fresh potable water, and generate approximately 40 percent of total waste. India is now entering the phase of rapid urbanization. Various studies indicate that by 2050, the built foot print of India may become four times the current mass, which may pose a major challenge in preserving our fragile environment. Although the present energy consumption per capita in India is a fraction of that of most developed nations, but with its projected growth, unless enough measures are taken, it may lead to acceleration of environment degradation, contributing to increased carbon footprint leading to global warming and climate change.

15. It is important to note that ‘green building’ is not a product
It is important to note that ‘green building’ is not a product. It is a process that starts right from
Site Selection
Design Phase
Solar Passive design, building envelope
A practical and climate conscious approach is taken while designing a green building. Various factors, like geographical location prevailing climatic conditions.

16. Choice of Materials Energy Efficiency
Building materials typically considered to be ‘green’ include renewable plant materials like bamboo and straw, dimension stone, recycled stone, recycled metal, and other products that are non-toxic, reusable, renewable, and/or recyclable.
Energy Efficiency
Conventional buildings consume copious amounts of energy. So, combining cutting-edge energy efficient technologies with adaptation of practices used in vernacular architecture especially for countries where per capita energy consumption is high will reduce the dependence on the fossil fuels.

20. Use of RE Water Efficiency
On site generation of renewable energy through solar power, wind power, hydro power, or biomass can significantly reduce the environmental impact of the building.
Water Efficiency
Reducing water consumption and protecting water quality key objectives in green buildings. The protection and conservation of water throughout the life of a building may be accomplished by designing for dual plumbing that recycles water in toilet flushing. Wast-water may be minimized by utilizing water conserving fixtures, such as ultra-low flush toilets and low-flow shower heads.

21. Reduction of Waste Construction Phase
In reducing waste, green building ensures that materials are used efficiently with minimal contribution to the landfill. A well- designed building also offers ways for the occupants to reduce their waste by using rainwater cisterns, composters and other things so that after the building is complete, waste is minimized at all stages. Well-designed buildings also help reduce the amount of waste generated by the occupants by providing on-site solutions such as compost bins to reduce matter going to landfills.
