• Green building (also known as green
construction or sustainable building) expands
and complements the building design
concerns of economy, utility, durability, and
• 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.
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 techniques associated with the `Green Building'
include measures to prevent erosion of soil,
rainwater harvesting, use of solar energy,
preparation of landscapes to reduce heat,
reduction in usage of water, recycling of waste
water and use of world class energy efficient
A similar concept is natural building, which is
usually on a smaller scale and tends to focus on
the use of natural materials that are available
OBJECTIVES OF GREEN
• Green Buildings are designed to reduce the
overall impact on human health and the
natural environment by the following ways:
• Using energy, water and other resources
• By reducing waste, pollution, and
Principles of Green Building
• Save energy
• Recycle buildings
• Create community
• Reduce material use
• Protect and enhance
• Select low-impact
• Maximize longevity
• Save water
• Make the building
• Minimize C&D waste
• Green up your business
• STRUCTURE EFFICIENCY:
It is the concept of sustainable building and has
largest impact on cost and performance.
It aims to minimize the enviornmment impact
associated with all life-cycles.
• ENERGY EFFICIENCY:
The layout of the construction can be strategised
so that natural light pours for additional warmth.
Shading the roof with trees offers an eco-friendly
alternative to air conditioning.
• WATER EFFICIENCY:
To minimize water consumption one should
aim to use the water which has been collected,
used, purified and reused.
• MATERIAL EFFICIENCY:
Materials should be use that can be recycled
and can generate surplus amount of energy.
An example of this are solar power panels,not
only they provide lightening but they are also a
useful energy source.
• WASTE AND REDUCTION:
It is probable to reuse resources.
What may be waste to us may have another
benefit to something else.
IMPORTANCE OF GREEN BUILDING
Nowadays, we should make a way to maximize our natural resources
and also help our mother earth to get some relief since pollution is
everywhere plus the global warming that we are all experiencing. 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.
The importance of this is it lessen the consume of energy and the
pollution as well because the more we use nonrenewable energy the
higher the risk of pollution.
ADVANCED SYSTEMS IN GREEN
• Installation of solar panels constructed using
organic solar cells for efficiency.
• The electrical energy is stored in a high PV
• It is also a hybrid system using the wind mill
• Allow high ventilation of air throughout the
• Making the sun light to enter into the building.
Principles of Green Materials
• Choose products:
– made from environmentally attractive materials
– that are green because of what isn’t there
– that reduce environmental impacts during
construction, renovation or demolition
– that reduce environmental impacts of building
– that contribute to a safe, healthy indoor environment
Materials, production, use and disposal must be safe for
the planet. Most of the materials have specific range of
conditions in which they best work
Sustainable building materials have the following
• Durable and easily maintained
• Less processing required
• Low odor
• Low emitting
Obtained by adding wool and a natural
polymer found in seaweed to the clay
of the brick, red bricks and blue
37% More strength than burnt bricks
Resistant for cold and wet climate
DIFFERENT FROM OTHER
• The design,maintaince and construction of
buildings have tremendous effect on our
enviornment and natural resources.
• Green Building is different from the other
buildings because it use a minimum amount of
nonrenewable energy, produce minimal pollution,
increases the comfort, health and safety of the
people who work in them.
• It also minimize the waste in construction by
recovering materials and reusing or recycling
