2. What is a green building?
A green building is a sustainable or a high performance building
which:
uses less water
optimizes energy efficiency
conserves natural resources
generates less waste
provides healthier space for occupants as compared to conventional
buildings
Green building is the practice of creating structures and processes
that are environment friendly and resource efficient throughout the
lifespan of a building right from site selection to design,
construction, operation, maintenance, renovation and
deconstruction.
3. Why green buildings ?
One of the main goals is to make Earth more sustainable
Global climate change has become an increasingly serious
concern for the future
At the rate we are developing, the earth is simply not
sustainable. In coming years, we will begin to run out of
certain natural resources that are needed in order for us to
survive.
The ideal green building would be a building project that
would allow us to preserve most of the natural environment
around the project site, while still being able to produce a
building that is going to serve a purpose.
4. Benefits
Environmental Benefits:
Reduce wastage of water
Conserve natural resources
Improve air and water quality
Protect biodiversity and
ecosystems
Economic Benefits:
Reduce operating costs
Improve occupant productivity
Create market for green product
and services
Social Benefits:
Improve quality of life
Minimize strain on local
infrastructure
Improve occupant health and
comfort
5. Issues for investment in green
buildings:
There is a misconception that going green costs more money and
hence people avoid it.
It may be a bit costly to get started because green materials and
products can be more costly, but the savings are more in the long
term.
Green building is more of an investment that will be able to save us
money, as well as an investment that will be able to help the
environment - a win-win situation for everyone!
6. Changing features of green buildings
It is to be noted that not all green buildings need to be
the same.
Different countries and regions have a variety of
characteristics all of which shape their approach to green
building, such as:
distinctive climatic conditions
unique cultures and traditions,
diverse building types and ages
wide-ranging environmental, economic and social priorities

8. Fundamental principles for going
‘green’:
Structure efficiency
Structure has a great impact on cost and performance
Energy efficiency
Using natural light and trees for shading rather than air-conditioning
Water efficiency
Minimising water consumption by proper collection and use, then purify and reuse
Material efficiency
Recyclable materials is better to use
Waste and toxic reduction
Waste from one thing can be an input for some other thing, if used wisely.
9. LEED - Leadership in Energy and
Environmental Design,
LEED is the most widely used green building rating system in the world.
LEED provides a framework to create healthy, highly efficient and cost-
saving green buildings.
LEED certification is a globally recognized symbol of sustainability
achievement.
10. Green Building Rating System India
There are two primary Rating systems in India.
GRIHA - Green Rating for Integrated Habitat Assessment
IGBC - Indian Green Building Council
GRIHA aims at ensuring that all kinds of buildings become green buildings.
GRIHA even rates non-air conditioned buildings as green and puts great
emphasis on local and traditional construction knowledge.
Green projects rated by IGBC fall under one of the following levels (in
ascending order): Certified, Silver, Gold and Platinum. The more the
energy efficient building, the higher the certification level
13. About Suzlon One Earth
It is the eco-friendly, self-sufficient headquarters of the company.
The campus is spread across 10 acres.
An office building campus with calm and cool atmosphere
32. Some green construction practices:
Using sustainable building materials like recycled glass and steel, as well as renewable materials like
bamboo and rubber.
Installing energy-efficient windows and doors.
Using lower-VOC (volatile organic compounds) paints.
Constructing green roof systems which provide onsite gardens, rainwater management and protection
from the effects of harmful UV light.
Adding water harvesting and purification systems that both manage and make the most use of rainfall.
Maximizing natural light, saves on lighting requirements also helps keeping buildings warm in colder
months.
Using renewable energy to power the building like solar panels and windmills.
33. Green building benefits
Healthier and happier workers—employees that work in green buildings report
fewer headaches, as well as improvements in asthma and allergy symptoms.
Greater likelihood a green building will sell for more money than a standard
building.
Additional business opportunities that come from appealing to an ever-growing
pool of conscious consumers.
Reduced energy costs and operating costs
Reduced Government tax incentives
Reduced maintenance costs
34. What if we ignore green building
concepts?
Because of indiscriminate use of concrete and conventional building
materials in urban areas, the normal atmospheric temperature is
relatively higher than areas with few buildings.
CO2 emissions from such buildings add to the environmental pollution
and global warming which might result in catastrophic consequences
such as:
Reduction in agricultural output and global food production
Rise in the sea level in coastal plains
Alteration in ecosystem and biodiversity pattern
Prolonged flooding in regions receiving abundant rainfall.
