Green buildings are structures designed and operated to reduce environmental impact. They use less water and energy, generate less waste, and use healthier and more sustainable materials than conventional buildings. The objectives of green buildings are to minimize resource usage during construction and operation, and to reduce carbon emissions, water usage, waste production and energy consumption by 35-50%. Green building techniques emphasize sustainable siting, energy and water efficiency, healthy indoor environments, and the use of sustainable materials like straw bales, grasscrete and rammed earth.

4. Green building (also known as green construction or sustainable building) is
the practice of creating structures and using processes that are environmentally
responsible and resource-efficient throughout a building's life-cycle from sitting to
design, construction, operation, maintenance, renovation and demolition.
A green building is one which uses less water, optimizes energy efficiency,
conserves natural resources, generates less waste and provides healthier space for
occupants as compared to conventional buildings.

6. OBJECTIVES
1. Buildings, as offices, are responsible for
around forty percent of the expenses
borne by the business in operations. It is
estimated that by the year 2050, the
residential and office buildings will
consume thirty eight percent of the total
global energy and will release three
thousand eight hundred mega tones of
carbon into the atmosphere. Green
Building is a technique of constructing
buildings using processes and materials
which are environment friendly and
energy efficient at the same time.
2. The objective of green building concept is
to develop buildings which use the natural
resources to the minimal at the time of
construction as well as operation. Green
buildings emphasize on the resource
usage efficiency and also press upon the
three R’s – Reduce, Reuse and Recycle.

7. OBJECTIVES
3. The technique of green building maximizes
the use of efficient construction materials
and practices Implementation of the green
building concept can lead to a reduction of
carbon emission by thirty five percent,
water usage by forty percent, solid waste
reduction by seventy percent and
reduction in energy consumption by fifty
percent.
4. To ensure minimum negative impact on the
environment by the construction and
operation of a building, the factors which
are to be kept in mind are – to preserve the
external environment to the building
location; to improve the internal area for
the residents of the building; and also
preserve the areas which are not close to
the building.7
9. FUNDAMENTAL PRINCIPLES

1. Sustainable Sitting:- this approach optimizes
land use and development to reduce adverse
impacts and minimize the building’s
ecological footprint.
2. Energy Efficiency :- this technique focuses
on the establishment of performance targets
that account for intended use, occupancy and
other energy operations for new construction
and renovation projects.
3. Water efficiency:- this technique emphasizes
the value of decreasing demands for fresh
water and reducing the generation of waste
water through optimized landscaping,
integrated rainwater catchments, and
wastewater treatment systems.
10. FUNDAMENTAL PRINCIPLES
10
3. Building Materials:- by using sustainable construction materials and resources,
green building materials have aided the reduction of extraction, processing,
transportation, solid waste, and consumption.
4. Healthy Indoor Environmental Quality:- these processes have enhanced the
sustainable communities through ventilation and thermal comfort, moisture
control, day lighting, environmental tobacco smoke control, and protecting
indoor air quality during construction.

SUSTAINABLE BUILDING MATERIALS FOR
CONSTRUCTION
1. Straw Bales
Rather than relying on new research and
technology, straw bale building hearkens
back to the days when homes were built
from natural, locally-occurring materials.
Straw bales are used to create a home’s
walls inside of a frame, replacing other
building materials such as concrete, wood,
gypsum, plaster, fiberglass, or stone. When
properly sealed, straw bales naturally
provide very high levels of insulation for a
hot or cold climate, and are not only
affordable but sustainable as straw is a
rapidly renewable resource.

2. Grasscrete
As its name might indicate,
grasscreteis a method of laying
concrete flooring, walkways,
sidewalks, and driveways in such a
manner that there are open patterns
allowing grass or other flora to grow.
While this provides the benefit of
reducing concrete usage overall,
there’s also another important perk
improved storm water absorption
and drainage.

3. Rammed Earth
What’s more natural than the dirt under
your feet? In fact, walls that have a similar
feel to concrete can actually be created with
nothing more than dirt tamped down very
tightly in wooden forms. Rammed earth is a
technology that has been used by human
civilization for thousands of years, and can
last a very long time. Modern rammed earth
buildings can be made safer by use of rebar
or bamboo, and mechanical tampers reduce
the amount of labor required to create
sturdy walls.

4. HempCrete
HempCrete is just what it sounds
like – a concrete like material
created from the woody inner
fibers of the hemp plant. The
hemp fibers are bound with lime to
create concrete-like shapes that are
strong and light. HempCrete
blocks are super-lightweight,
which can also dramatically reduce
the energy used to transport the
blocks, and hemp itself is a fast-
growing, renewable resource.

5. Bamboo
Bamboo might seem trendy, but it has
actually been a locally-sourced building
material in some regions of the world for
millennia. What makes bamboo such a
promising building material for modern
buildings is its combination of tensile
strength, light weight, and fast-growing
renewable nature. Used for framing
buildings and shelters, bamboo can
replace expensive and heavy imported
materials and provide an alternative to
concrete and rebar construction,
especially in difficult-to reach areas,
post-disaster rebuilding, and low-
income areas with access to natural
locally-sourced bamboo.

people, ‘One Earth’ is another
building that has received Platinum
certification of LEED. The building is
built using low energy materials thus,
reducing carbon footprint. 90 percent
of the occupied space of the building
has access to natural daylight. While
the exterior of the building uses
renewable energy-based LED street
lighting reducing approximately 25
percent of the total power. The
ventilation system consists of jet fans
that save 50 percent energy by
periodically pushing out stale air and
bringing in the fresh air.

Indian Green Building Council
1. The Indian Green Building Council (IGBC) was formed by the Confederation
of Indian Industry (CII) in 2001
2. The vision of the council is, "To enable a sustainable built environment for all
and facilitate India to be one of the global leaders in the sustainable built
environment by 2025".
3. The council offers a wide array of services which include developing new green
building rating programmes, certification services and green building training
programmes. The council also organizes Green Building Congress, its annual
flagship event on green buildings.
4. The council is committee-based, member-driven and consensus-focused. All
the stakeholders of construction industry comprising of architects, developers,
product manufacturers, corporate, Government, academia and nodal agencies
participate in the council activities through local chapters.

IGBC Rating System
Indian Green Building Council (IGBC) Green Factory Buildings is the first
rating program me developed in India, exclusively for the industrial sector. It is
based on accepted energy and environmental principles and strikes a balance
between known established practices and emerging concepts. The system is
designed to be comprehensive in scope, yet simple in operation. This rating
system would address the factory buildings and not the processes. It would be
applicable to all sectors of industry and for all climatic zones of India.

INCREASING GREEN BUILDING IN
INDIA
Almost 14 lakh houses in India have
chosen to go for a ‘green building’ tag
which amounts to about 6.33 billion
sq ft. It however constitutes mere 5%
of total residential properties present
in the country.
India now has an ambitious target of
having 10 billion sq ft green building
footprint by 2022. It is expected to
increase the green footprint by around
10%.

CONCLUSIONS
Green building is a financially, health, and most importantly environmentally
responsible idea that more people need to adopt. The United States Green Building
Council developed LEED in order to help customers, designers, and builders to work
together to create buildings with the minimal impact on the environment
possible. Many building materials and renewable energy sources exists to lessen
one’s impact upon the environment. Through educating, making environmentally
products more readily accessible and reliable, and by providing government
incentives it is possible to encourage more people to adopt green building and all of
the benefits that come along with it.
