GREEN BUILDING ?
We can still SAVE THE EARTH !!
5. What is a GREEN BUILDING ?
Green building - also known as sustainable or high performance
building - is the practice to:
Have minimum demand for electricity, water and other natural
resources(in construction, demolition and operation).
Generate all its electricity on site through renewable means.
Strive to cater to all its water demand through sustainable
processes such as rain water harvesting.
It could also strive to grow its own food in site.
It would recycle and reuse all its waste on site.

8. ENVIRONMENTAL BENEFITS
Enhance and protect biodiversity and
ecosystems
Improve air and water quality
Reduce waste streams
Conserve and restore natural
resources
We can still SAVE THE EARTH !!
9. REAL BARRIERS TO GO GREEN
a lack of planning and developer education.
a lack of knowledge about local vendors and resources
difficult local land use officials.
Rather than taking the initiative, several developers only work to
improve business practices when competition forces them to do so.

10. BROAD FUNCTIONS OF A BUILDING
• Apart from the basic functions as a shelter, a building should provide 2
fundamental physiological comforts, to its occupants they are:
The ability to allow occupants to see
Visual comfort clearly for carrying out their daily
domestic official task.
The ability to allow occupants to
Thermal comfort remain cool in the summer and warm in
the winter.
We can still SAVE THE EARTH !!
11. These comforts can be provided in two ways:
Naturally (Using sunlight, natural
wind, evaporation, trees, etc) thus
saving energy.
(Using electric lighting, AC’s, etc) thus
Artificially relying on large scale energy generation
leading to pollution and green house
gas emission.
We can still SAVE THE EARTH !!
12. Lack of proper information and tendencies to follow
fashionable trends that are short lived often lead us
to provide comfort condition in our building at the
cost of very high energy consumption.
It should be our Endeavour to help secure energy
and resource for future of our country through
green buildings and habitats suitable for our
country and people.
We can still SAVE THE EARTH !!
13. HOW DO BUILDING EFFECT
ENVIRONMENT??
To provide all the comforts listed above , a building needs to consume resources for
construction and operation. In our country, a well designed building is built out of
concrete and brick, and may have a design life up to 100 years. During such a period,
a building can consume unimaginable quantities of resources.
Building consume resources such as:
Land Farms, forests, fertile land, marshes etc.
Soil Earth,sand,stone,clay,lime,silica,etc.
Trees Wood, ply, board, shuttering, etc.
Metals Steel, iron, aluminum, copper, lead, etc.
plastics PVC, UPVC, PU, etc.
Water Construction, landscape, cooling,
washing, drinking, flushing, etc.
Electricity Cooling/ heating, lighting, pumping,
entertainment/ working, etc.
We can still SAVE THE EARTH !!
14. And building generates wastes such as:
Site wastes Cut trees, and vegetation and
excavated soil, blasted stones,
rubbles, etc.
Construction wastes Metal boxes/cans, broken bricks,
shuttering oil, etc.
Sewage/ sullage Black water, grey water, etc.
Organic wastes Peels, vegetables, fruits, etc.
Recyclable wastes Paper, glass, metals, etc.
Non-Recyclable Demolition debris, all plastics,
wastes synthetics, fibers, etc.
E wastes CD, electronic, hardware, etc.
Chemical wastes Adhesive, paints, etc.
We can still SAVE
THE EARTH !!
15. HOW DO BUILDING EFFECT CLIMATE??
The energy used to heat and power our buildings leads to the
consumption of large amounts of energy, mainly from burning
fossil fuels - oil, natural gas and coal - which generate significant
amounts of carbon dioxide (CO2), the most widespread
greenhouse gas.
Reducing the energy use and greenhouse gas emissions
produced by buildings is therefore fundamental to the effort to
slow the pace of global climate change. Buildings may be
associated with the release of greenhouse gases in other ways,
for example, construction and demolition debris that degrades in
landfills may generate methane, and the extraction and
manufacturing of building materials may also generate
greenhouse gas emissions.

17. GREEN BUILDING CONCEPT
The `Green Building' concept is gaining importance in
various countries, including India. These are buildings that
ensure that waste is minimized at every stage during the
construction and operation of the building, resulting in low
costs, according to experts in the technology.
The techniques associated with the `Green Building' include
measures to prevent erosion of soil, rainwater harvesting,
preparation of landscapes to reduce heat, reduction in usage
of potable water, recycling of waste water and use of world
class energy efficient practices.

19. SELECTION CRITERIA OF GREEN BUILDING
MATERIALS
Resource Efficiency
– Recycled content
– Renewable
– Efficient manufacturing process
– Local availability
– Easily recyclable
– Recyclable Packaging
– Product Durability
Energy Conservation
Water Conservation
20. LIST OF GREEN BUILDING MATERIALS
Flooring: Flooring is good place to start when trying to make greener
building choices. Some woods are less renewable than others, and carpet
often contains VOCs (volatile organic compounds) that have a negative effect
on indoor air quality. Bamboo has become a popular choice for flooring, since
it replenishes very quickly. Cork, which is removed from the outside of a living
tree at intervals, is attractive, natural, very renewable and gentle on the
human body. Other green flooring options include sisal, eucalyptus, recycled
carpet tiles, recycled rubber, wool carpeting, linoleum and reclaimed wood.
21. Cement:
On driveways and walkways, specially engineered cement that is porous and allows
water to sink in rather than run off and pollute waterways is environmentally friendly.
Also, using light-colored concrete, especially in urban areas, helps reduce
temperature. For buildings, a relatively new technology called TX Active has emerged,
which actually "eats" pollution.
Insulation:
Insulation is very important in green construction because it helps conserve energy. In
the past, asbestos was used for insulation, but it has since been banned or restricted
in many countries because of health hazards. Good sustainable choices for insulation
are those made from recycled newspaper and wood pulp, soy, cotton, recycled plastic
or cork.
Glass:
Break through in technology have made glass a popular green building material.
Windows constructed of layered panes separated by sealed, gas-filled compartments
provide insulation that conserves energy. Additionally, windows and doors can also be
covered in special low-emissivity coatings that use or block natural solar rays to help
regulate indoor temperatures.
22. Roofing:
An important feature of green roofing is its durability; sustainability can often be as
simple as avoiding or limiting waste. Composite cedar shingles resist moisture, mildew
and insects, which extends their life. Metal roofing materials that have solar reflective
qualities also have advantages, especially in hot climates. Living roofs, which are
covered in hearty plant life, reduce the "heat island effect" that is caused by a lack of
evapotranspiration in areas that have a lot of concrete and asphalt surfaces.
23. GRIHA- “Green Rating for Integrated Habitat
Assessment”
GRIHA is India’s national rating system for green buildings. It has been
developed by TERI( The Energy and Resources Institute) and is endorsed by
MNRE( Ministry of New and Renewable Energy).
GRIHA attempts to minimize a building’s resource consumption, waste
generation and overall ecological/environmental impact by comparing them to
certain nationally accepted limits/benchmarks.
It does so using the five ‘R’ philosophy of sustainable development namely-
REFUSE- To blindly adopt international trends, material, technologies,
products, etc. specially in cases where local substitutes/equivalents are
available.
REDUCE- The dependence on high energy products, systems, processes,
etc.
REUSE- Materials, products, traditional technologies, so as to reduce the
cost incurred in designing building as well as to operate them.
RECYCLE- All possible wastes generated from the building site during
construction, operation and demolition.
REINVENT- Engineering systems, designs and practices such that India
creates global examples that the world can follow rather than us following
24. GO GREEN !
From the planning stage through occupancy, green buildings offer many opportunities to
the developer and its occupants
Developers who have successfully navigated their way through the process of
building green have become converts and
no longer see it as a difficult task
Going Green has led to an enhancement of many a developer’s
corporate image!
