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?
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
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.
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-anycost, 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.
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.
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.
 Choice of Materials
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.
 Use of RE
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.
 Reduction of Waste
In reducing waste, green building ensures that materials are used
efficiently with minimal contribution to the landfill. A welldesigned 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 onsite solutions such as compost bins to reduce matter going to
landfills.
 Construction Phase
 Operation and Maintenance phase
