GREEN BUILDING
BUILDING THE FUTURE WITH
INTENTION
1
WHAT IS GREEN BUILDING
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.
2
Green building
The Design and
construction
practices that
significantly reduce
or
eliminate the
negative impact of
buildings on the
environment and its
occupants. Green
Buildings are the
Eco-Friendly
Structures .
A green building
may cost more up
front, but saves
through lower
operating costs over
the life of the
building. The green
building approach
applies a project life
cycle cost analysis for
determining the
appropriate up-front
expenditure.

The concept of Green
Building Technology
envision a new approach
to save water, energy
and material resources
in the construction and
maintenance of the
buildings and can
reduce or eliminate the
adverse impact of
buildings on the
environment and
occupants.

The fundamental
objectives of green
buildings are to
conserve natural
resources and increase
energy efficiency.
Increasing energy
efficiency involves
harnessing nature to
minimize need for
energy for operation
and maintenance of
the building.

FACTORS of
Location :-
a green building site
should be selected based on
how easily it can integrate into
the existing electric, gas,
water, and sewage utilities.
Fitting into a city’s existing
infrastructure so that a
project has the smallest impact
on the existing energy, water,
sewage and road systems is the
first point at which the green
decision making process comes
into play.
green building
Orientation:-
A green
building should organically fit
into the surrounding area,
making best use of existing
roads, sidewalks, alleys, site
specific solar resources and
so forth.
Day light:-
Day lighting is the
controlled admission of
natural light—direct sunlight
and diffuse skylight—into a
building to reduce electric
lighting and saving energy.
Day lighting is an important
element of sustainable
design.
FACTORS of
green building
Renewable energy :-
Renewable energy comes
from natural sources such as
sunlight, geothermal heat,
wind, water, and biofuels
powered by feedstock.
Waste water management:-
Rainwater harvesting:-
The main purpose of rainwater
harvesting system to collect
and store rainwater falling on
the ground which can be
further be used in the future.
Wastewater management or the
lack of, has a direct impact on the
biological diversity of aquatic
ecosystems, disrupting the
fundamental integrity of our life
support systems, on which a wide
range of sectors from urban
development to food production
and industry depend.
Materials Used In Green
Constructions

Wool brick
Obtained by adding wool
and a natural polymer found
in seaweed to the clay of the
brick,
37% More strength than
burnt bricks

Solar Tiles
 Exist to simply protect
a building
 They spend a large
portion of the day
absorbing energy from
the sun.

The Druk White Lotus School Ladakh
In this desert landscape of
severe climatic conditions,
3,500 meters above sea
level, was born a modest
school .
• This multi-award winning
structure is the recipient of
the Best Asian Building,
Best Education Building
and Best Green Building
awards. It combines the
best of traditional Ladakhi
architecture with 21st
century engineering
excellence .
Traditional mud brick
masonry is used internally to
provide increased thermal
performance and durability
CONCLUSION:
Non-renewable energy is expensive and unsafe but
did you know that through green building we can save
a lot of energy.
Before that, let's define first the meaning of green
building (know also as green construction is the
practice of creating structures and using processes that
are environmentally responsible and resource-efficient
throughout a building's life-cycle: from siting to
design, construction, operation, maintenance,
renovation, and deconstruction.
