It gives you brief description about the types of green buildings. Difference between the GRIHA process and LEED process. Rating system of both the processes.

1. GREEN BUILDINGS
By
Suguru Anusha.

2. What is Green Buildings?
 A green building is one which uses less water, optimises energy efficiency, conserves
natural resources, generates less waste and provides healthier spaces for occupants, as
compared to a conventional building.
 Building green is not about a little more efficiency. It is about creating buildings that
optimize on the local ecology, use of local materials and most importantly they are built to
cut power, water and material requirements.
 Building construction became major energy consuming sector in the economy. About 35 to
40% of the total energy is used by buildings during constructions.

3. Benefits of Green Building
 Reduced energy and water consumption without sacrificing the comfort level.
 Improved thermal comfort and better ventilation.
 Limited waste generation due to recycling process and reuse.
 By following green house norms, productivity in workplace can be increased by about 25 %.
 The activities of green building result in reduction of operating costs by 25% - 30%.
 Green building can reduce: -
 25 – 40% of Energy Usage
 37% of CO2 Emissions
 40% of Water Usage
 70% of Solid waste

4. Materials Used in Green Buildings
1. Wool Bricks:
 It is obtained by adding wool and a natural polymer found in seaweed to the clay of the
brick.
 It gives 37% more strength than burnt bricks.
 Resistant for cold and wet climate.
2. Sustainable Concrete:
 CO2 emission can be reduced by using blended cement in which industrial by product like
slag that replaces part of clinker.
 It reduces the emission of CO2.

5. Materials Used in Green Buildings
3. Solar Tiles:
 It exists to simply protect a building.
 They spend a large portion of the day absorbing energy from the sun.
4. Paper Insulation:
 Made from recycled newspapers and cardboard.
 Then filled with chemical foam.
 It is a insect resistant & fire retardant.

6. Materials Used in Green Buildings
5. Triple – Glazed Windows:
 Super – efficient windows.
 Stops heat to enter the building & from direct sunlight.

7. Merits of Green Buildings
 Efficient Technologies
 Easier Maintenance
 Return on Investment
 Improved Indoor Air Quality
 Energy Efficiency
 Water Efficiency
 Waste Reduction.
 Temperature Moderation
 Water Conservation
 Economical construction for poor
 Healthier lifestyles and recreation
 Improved health.

8. Demerits of Green Buildings
 Initial cost is high
 Availability of materials
 Need more time to construct
 Need skilled worker.

9. GRIHA
GRIHA – GREEN RATING FOR INTEGRATED HABITAT ASSESSMENT
 It is a India’s own rating system jointly developed by TERI and the MINISTRY OF NEW &
RENEWABLE ENERGY.
 It has three – tier evaluation process.
 Step 1: Online submission as per prescribed criteria
 Step 2: Site Visit by team of professionals & experts
 Step 3: Evaluation process by the team.
 GRIHA rating system consists of 34 criteria categorised in 4 different sections.
i. Site selection & Site planning
ii. Building planning and construction stage
iii. Building operation maintenance
iv. Innovation

13. GRIHA
 GRIHA is a 100 – point system consisting of some core points.
 Different levels of certification (one star to five starts) are awarded based on the number
of points earned. The minimum points required for certification are 25.

17. LEED
LEED stands for THE LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN
 It is designed and started by IGBC (Indian Green Building Council)
 It is an internationally accepted benchmark for the design, construction and operation of
high performance green building.
 LEED History:
 Over 10 years in development
 Available to the public in march of 2000
 Initially 1 program (for new construction only)
 Now 7 different LEED Rating programs.

18. LEED Types

19.  A project must satisfy all LEED prerequisites and earn a minimum of 40 points on a 110
– points LEED rating system scale.
LEED RATING SYSTEM

20.  The 8 LEED categories are:
i. Innovation & Design process – 11 points
ii. Location & Linkages – 10 points
iii. Sustainable sites – 22 points
iv. Water efficiency – 15 points
v. Energy & Atmosphere – 38 points
vi. Material & resources – 16 points
vii. Indoor environmental quality – 21 points
viii. Awareness & education – 3 points
LEED Categories

21. LEED Process

22.  Lower operating costs and increase asset value
 Reduce waste sent to landfills.
 Conserve energy and water.
 Be healthier and safer for occupants
 Reduce harmful greenhouse gas emissions.
Why LEED?

23. 1. ITC GREEN CENTER – Gurgaon.
 It is LEED PLATINUM certified building with 56 points.

24. Difference Between GRIHA & LEED
GRIHA LEED
It is with Indian standards It is benchmarked with global standards
Suits to Indian realities Complicated for Indian realities
India per capita energy consumption is
very low compared to developed nations.
Primarily based on per capita energy
consumption in developed nations like
US.
