3. Adverse effects of Construction
According to a research by construction blog Bimhow ,the
construction sector contributes to
• 23% of air pollution,
• 50% of the climatic change,
• 40% of drinking water pollution,
• 50% of landfill wastes.
In separate research by the U.S. Green Building Council
(USGBC), the construction industry accounts for 40% of worldwide
energy usage, with estimations that by 2030 emissions from
commercial buildings will grow by 1.8%.

4. The construction industry in India is growing rapidly at a rate of 10% compared with the
world average of 5.2%.
It is observed that buildings in India consume
about 20% of the total electricity in the country.
Hence, real estate activity in India has
a significant impact on the environment
and resources.

5. What is Green
Building?
Introduction
According to US EPA
“Green building is a practice of creating
structures and using processes that are
environmentally responsible and resource
efficient throughout a building’s life cycle from
siting to design, construction, operation,
maintenance, renovation, and
deconstruction.”
AIM:
The aim of green building design is to minimize
resources, maximize the reuse, recycling and
utilization of renewable resources.

6. Why Green Buildings?
• Structure efficiency :-
It is the concept of sustainable building and has largest impact on cost and performance. It
aims to minimize the environment impact associated with all life-cycles.
This can be achieved through following designing techniques :-
• Bioclimatic architecture
• High performing building envelope
• High performance controlled ventilation

7. • Energy efficiency :-
Energy efficient buildings can be defined as buildings that are designed to provide a
significant reduction of the energy needed for heating and cooling, independently of the
energy and of the equipment that will be chosen to heat or cool the building.

buildings

8. • Water efficiency :-
Water efficiency in a building may be accomplished by designing for dual plumbing that
recycles water in toilet flushing. Waste-water may be minimized by utilizing water conserving
fixtures such as ultra-low flush toilets and low-flow shower heads.

9. • Waste and toxic efficiency :-
It is probable to reuse resources. What may be waste to us may have another
benefit to something else.
Recycle Concrete
Fly Ash Bricks

10. Benefits of GB :-
• The application of integrated design, leads to reduce the initial costs of the
building.
• The implementation of intelligent design and suitable materials
• Every Green Building will have to purge continuous fresh air to meet
the ASHRAE 62 requirements

11. • Green buildings certified by the IGBC results in
water savings of 20 – 30% and energy savings of
40 – 50% compared to conventional buildings
in India.
• save 20% of total construction costs
over the life of the building
• Over 20 years, the financial payback
typically exceeds the additional cost
of greening by a factor of 4-6 times..

12. Green Building Rating Tools in India :-
Rating tools set benchmark for green building measurement, which are helpful in reducing
negative impact on environment by promoting quality green buildings.
India currently has the below green rating systems for buildings:-
 Green Rating for Integrated Habitat Assessment (GRIHA)
 Leadership in Energy and Environment Design (LEED)
 IGBC rating systems

13. 1. INDIAN GREEN BUILDING COUNCIL (IGBC) RATING
SYSTEM :-
The unique aspects addressed in this rating system are:
 Recognition for architectural excellence through integrated
design approach.
 Recognition for passive architectural features.
 Structural design optimization with regard to steel and cement.
This is a developmental credit. Projects are encouraged to attempt
this credit, so as to help IGBC in developing baselines for future use.
 Water use reduction for construction. This is also a developmental credit.
 Handholding from IGBC Counsellors will now be available for the projects

15. 2. GREEN RATING FOR INTEGRATED HABITAT
ASSESSMENT (GRIHA):-
It is based on accepted energy and environment principles, seeks to strike a balance between the
established practices and emerging benefits.
GRIHA is the best suitable for Indian climate.
The system was developed to 'design and evaluate' new buildings. A building is evaluated based
on its performance that was predicted for its entire life span – inception through operation.
The stages of the life cycle that are identified for assessment are:
 Pre-construction stage
 Building planning and construction stages
 Building operation and maintenance stage

GRIHA stars: A building has to earn a minimum of 50
points out of a total 100 to qualify for Green Rating.
• 50 - 60 points = 1 star
• 61 - 70 points = 2 stars
• 71 - 80 points = 3 stars
• 81 - 90 points = 4 stars
• 91-100 points = 5 stars
All buildings that have an area of more than
2,500 square meters are rated by using GRIHA
rating system.

17. LEED is also a classification system devised by the US Green Building Council (USGBC) to
classify the environmental conduct of a building.
It is the most widely used green building rating system in the world.
LEED India encompasses rating systems for:
• Existing Buildings (EB)
• New Construction (NC)
• Core and Shell (C&S)
• Green Homes
Based on the points achieved, the building may be eligible for LEED-certified, Silver, Gold or
Platinum Rating.
