GREEN BUILDING & LEED
Green building is the practice of:
1. Increasing the efficiency with which buildings use and harvest energy, water & materials
2. Reducing building impacts on human health and the environment
Key Elements of a Green Building:
Energy efficient- a generally tight house with energy efficient use of water,
energy efficient appliances, windows
Cooling and Heating units and HVAC and ventilation systems.
Recycled content used in the building process
Uses environmentally sustainable materials like bamboo
Uses the building lot or site in a sustainable manner
Use of locally manufactured goods
Water conservation
Indoor environmental air quality

GREEN BUILDING & LEED
Importance
Save money, increase comfort & create healthier environments for
people to live and work
Improved indoor air quality, natural daylight & thermal comfort.
Energy use by depleting natural resources as well as CO2 emissionsis one of our most important environmental impacts.
Volatile energy markets, rising energy costs and increasing
environmental awareness about issues such as global warming make
energy efficiency and conservation a high priority.

Materials used in a Green Building :
For Energy efficiency :
Usage of high efficiency windows & insulation in walls, ceilings & floors
Orient windows and treesto shade windows & roofs during the summer while
maximizing solar gain in the winter
Effective window placement can provide more natural light and lessen the need for
electric lighting during the day
Use of Solar water heating
Use of renewable energy through solar power, wind power, hydro power or biomass
Creating a high performance luminous environment through the careful integration of
natural and artificial light sources will improve on the lighting quality of a structure

GREEN BUILDING & LEED
Materials used in a Green Building :
For Water efficiency :
Designing 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
Eliminate the use of toilet paper, reducing sewer traffic and increasing
possibilities of re-using water on-site
Usage of Greywater or wastewater from sources such as dishwashing
or washing machines, can be used for subsurface irrigation, or if treated,
for non-potable purposes, e.g., to flush toilets and wash cars.
Rainwater collectors are used for similar purposes

GREEN BUILDING & LEED
Materials used in a Green Building :
For Material efficiency :
Usage of rapidly renewable plant materials like bamboo
Usage of recycled stone, recycled metal, and other products that are
non-toxic, reusable, renewable, and/or recyclable, e.g. - fly ash bricks,
Using recycled industrial goods, such as coal combustion products,
foundry sand, and demolition debris in construction projects .
Building materials should be extracted and manufactured locally

GREEN BUILDING & LEED
Materials used in a Green Building :
For Waste Reduction :
Converting waste and wastewater into fertilizer - by collecting
human waste at the source and running it to a biogas plant with
other biological waste, liquid fertilizer can be produced. This will helpreduce greenhouse gas emission
Installation of waterless urinal

Rashtrapati Bhavan the most eco friendly building of the country :
'Project Roshini', launched in the first week of July, 2008, is an endeavour to make the 355-room President's
house estate an eco-friendly township
There are unique projects like recycling of water, world's biggest rainwater harvesting system, use of natural
gas and biogas instead of LPG, zero waste management system and estate is plastic-free zone, a vermi
compose pit has been set up in the premise.
The estate also houses 2,000 households besides contingents from the army, the President's bodyguards,
ITBP and the Delhi Police.
The Bhawan is equipped with stringent energy audit; all housing is using CFL lighting and solar lamps. There
is proper environmental policy and auditorium run on solar power.
Electric cars and carts are provided for running local tasks within the campus.
Ministry of Renewable Energy has also approved a Rs three-crore project to set up solar panels so that thelamps in the Rashtrapati Bhavan could run totally on solar energy

LEED : The Leadership in Energy and Environmental Design
An environmental rating and certification system for residential and commercial buildings from the U.S.
Green Building Council
LEED provides benchmarks for :
Design
Construction and operation of a property
Covers site makeup , building materials, water and energy efficiencyIndoor environmental quality
It also provides certification for people who demonstrate an understanding of green building practices
Evaluation Tools used for measuring factors of Green Building :
A number of software tools are used for measuring energy simulation, day lighting, environmental impact
assessment and surface water run-off calculations.

2) Comprehensive Assessment System for Building Environmental Efficiency (CASBEE)
3) GB Tool
4) Green Globes US
5) LEED
After considering various rating systems, the Indian Green Building Council (IGBC) decided to adopt the LEED
rating system. This system in India is known as LEED India
LEED-INDIA provides building owners, architects, consultants, developers, facility managers and projectmanagers the tools they need to design, construct and operate green buildings.
