2. Introduction
Our ancestors worshipped the five elements of nature-
Earth as ‘prithvi’
Water as ‘jal’
Agni as ‘energy’
Air as ‘vagy’
Sky as ‘akash’
A green building or environmental building or sustainable building is a building which seek to
harness all these natural elements in its design and construction to an optimum level so as to have an
eco-friendly, low energy & low water consumption building and at the same time providing fresh and
healthy environment to its occupants.
3. Green building in India
•The first green building in India, CII – sohrabji godrej green business centre in Hyderabad, was
inaugurated on 14 July 2004. (platinum rated)
•The centre for environmental sciences and engineering (CESE) building at the IIT-Kanpur
became the first building in India to be awarded five-star green rating for integrated habitat
assessment (GRIHA) RATING by TERI (the energy and resources institute, new Delhi) in 2009.
•ITC green centre, Gurgaon – platinum rated green building.
•Wipro technologies, Gurgaon – platinum rated green building.
•Grundfos pumps, Chennai – gold rated green building.
•NEG micon, Chennai – gold rated green building.
•Suzlon one earth, pune – 5 star
4. Goals of green building
•To make optimum use of five elements of nature i.e. ‘prithvi’, ’jal’, ‘energy’, ‘vayu’ and ‘akash’.
•To make minimum use of energy in building design, construction, use and maintenance.
•To reduce use of water in a building.
•To minimize damage to the environment.
•Re-use of waste materials in the construction.
•To reduce the production of wastes during construction.
•To reduce production of greenhouse gases (GHG).
•To maintain equilibrium of the environment.
•To provide fresh and healthy environment to the occupants of a building.
•To promote use of ‘local materials’ in the construction.
5. Principals of green building
•Sustainable site selection
•Energy efficiency
•Water efficiency
•Material efficiency
•Design efficiency
•Occupant health and safety
6. Threats of Climate Change
•Floods
•Droughts
•Storms
•Fire
•Earthquake
•Rising sea level
•Endangered species and plants
•No Drinking Water
•Starving Humans----etc.
7. •Fly ash
•Green concrete
•Use of scape and recycled aggregate in concrete
•Other waste materials such
Blast furnace slag
Silica fume
Red mud
Marble dust
Cinder
Waste glass
Jute fibers
•Wood salvaged from old buildings has been used for doors and windows
•Wood substitutes like
Various green material
8. Advantages of green building
Economic benefit
• Energy efficiency: green buildings are around 25-30% more energy efficient, with gold-rated buildings
as much as 37% efficient.
• Water efficiency: green buildings use 20-30% less water compared with similar conventional buildings.
This reduces operating water costs.
• Optimize life-cycle economic performance.
Environmental benefits.
• Enhance and protect ecosystems and biodiversity.
• Improve air and water quality.
• Reduce solid waste.
Health and community benefits
• Improve air, thermal and acoustic environment.
• Enhance occupant comfort and health.
• Enhanced image and marketability.
9. Disadvantages of green building
•Increases in 15-20% coast as compared to ordinary building.
•Modern techniques are required.
•Expert knowledge of the persous in the field in necessary.
Green Building Concept
•Sustainable site planning
•Building Design optimization
•Energy performance optimization
•Renewal energy utilization
•Water and Waste management
•Solid waste management
•Sustainable building material and construction technology
Health, well-being and environmental quality
10. Green Building Rating System
A green building rating system is an evaluation tool that measures environmental performance
of a building through its life cycle
Comprises of a set of criteria covering various parameters related to design, construction and
operation of a green building
Each criterion has pre-assigned points and sets performance benchmarks and goals that are
largely quantifiable
A project is awarded points once it fulfills the rating criteria. The points are added up and the
final rating of a project is decided.
Globally, green building rating systems are largely voluntary in nature and have been
instrumental in raising awareness and popularizing green building designs.
11. Successful International Rating Programs:
BREEAM
Building Research Establishment’s Environmental Assessment Method
(BREEAM) was developed in UK in 1990
•Covers a range of building types: offices, homes, industrial units, retail units, and schools.
•Points are awarded for each criterion and the points are added for a total score.
•The overall building performance is awarded a ‘Pass’, ‘Good’, ‘Very Good’ or ‘Excellent’ rating based
on the score.
•BREEAM has separate criteria/checklist for evaluation of
-Design and Procurement
-Management and Operation of buildings
•There is also a set of core credits that can be applied for, in case if the building wishes to go in for
‘Core only’ assessment for building performance.
12. Successful International Rating Programs:
LEED
•Leadership in Energy and Environmental Design (LEED®) was developed and piloted in the US in
1998 as a consensus-based building rating system based on the use of existing building
technology.
•The rating system addresses specific environmental building related impacts using a whole
building environmental performance approach.
•The Indian Green Building Council has adapted LEED system and has launched LEED India
version for rating of new construction.
•Indian Green Building Council (IGBC) has launched several other products for rating of different
typologies of buildings including homes, factories, among others.
13. 34 rating criteria
