This document discusses green buildings and sustainable construction. It begins by defining green buildings as those that use less water and energy resources, generate less waste, and provide healthier spaces for occupants compared to conventional buildings. The key objectives of green buildings are to minimize environmental impacts, optimize energy and water efficiency, and promote occupant health. Some examples of green building strategies and technologies used in India are discussed, such as solar air conditioning, green roofs, hybrid solar systems, high performance building envelopes, and radiant cooling. The growth of green building in India since 2002 and its economic and environmental benefits are also summarized.

GREEN BUILDINGS OR SUSTAINABLE
BUILDING DEVELOPMENT

2. • Green building (also known as green
construction or sustainable building) expands
and complements the building design concerns
of economy, utility, durability, and comfort.
• 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.
INTRODUCTION

3. CONCEPT ON GREEN CONSTRUCTION
OR BUILDING
• The design…...
• ...of our homes is fundamental to
our quality of life, comfort and
how affordable they are to run
• ...of our schools leaves a life-long
imprint on those who learn within
them, influencing pupil
concentration and how
environmentally aware the next
generation is

4. CONCEPT ON GREEN CONSTRUCTION
OR BUILDING
• The design…...
• ...of our workplaces impacts
employee productivity, health and
the prosperity of our companies
• ...of our hospitals affects patient
recovery times and National
Health Service bills
• ...of our cities and communities
strongly determines their
economic and social dynamics

5. OBJECTIVES OF GREEN BUILDING
• Low Impact
–Minimize impact on natural environment
• Energy Efficient
–Reduced Energy usage and Water usage
• Healthy
–Protect occupant health and increase
productivity
• Minimize waste
–Designed and constructed in a manner that
minimizes waste, pollution, and
environmental degradation

6. KEY ATTRIBUTES OF SUSTAINABLE
BUILDING
• Consideration of sustainability aspects in all
phases of building design and planning
• Use of healthy and environmentally friendly
building materials and products
• Use of efficient systems
• Use of constructions and systems which are
easy to maintain and service
• High aesthetic and urban design quality; high
public acceptance

7. FUNDAMENTAL PRINCIPLES
INVOLVED IN DEVELOPMENT OF
GREEN BUILDING
• Structural efficiency
• Energy efficiency
• Water efficiency
• Waste efficiency

8. • Its main intensions is
to minimize the total
environment impact
associated with all
life- cycles.
• It has the largest
impact on cost and
performance of
building.
STRUCTURAL EFFICIENY

9. ENERGY EFFICIENCY
• The strategy is to reduce
the operating energy use.
• Renewable energy
through solar power,
wind power, hydro power
and biomass can
significantly reduce the
environmental impact of
a building.

10. WATER EFFICIENCY
• Reducing water
consumption and
protecting water quality
is the key objectives of
sustainable building.
• The use of non-sewage
and greywater for on-
site use such as site-
irrigation will minimize
demands on the local
aquifer.

11. MATERIALS EFFICIENCY
• Buildings materials
should be renewable
materials , recycle and
friendly to the
environment.
• Examples are lumber
from forest, renewable
plant materials like
bamboo and straw and
other products that are
non-toxic, reusable,
etc.

12. GREEN BUILDING RATING SYSTEM
• The Indian Green Building Council (IGBC)
provides LEED ratings to structures in India and
Green Rating for Integrated Habitat Assessment
(GRIHA) is the National Rating System of India.
• Each rating system divided into different level of
certification is as follows:
• ‘Certified’ to recognise best practices.
• ‘Silver’ to recognise outstanding performances.
• ‘Gold’ to recognise national excellence.
• ‘Platinum’ to recognise global leadership.

13. ENERGY EFFICIENCY IN INDIAN
BUILDING
• The benefits of energy efficiency in building are
compelling, cost effective and can help consumers
to save money in the long term. It helps to meet
energy targets and resource energy shortage.
• There is an urgent need to improve the energy
efficiency of the Indian economy. About 70% of
the infrastructure in 2030, such as buildings, will
be added in next two decades
• The projections for energy demand in 2032 imply
a fourfold increase in requirements.

14. GREEN BUILDING IN INDIA

CAMPUS,HYDERABAD

17. GROWTH OF GREEN BUILDING
SINCE 2002

18. GREEN BUILDING ECONOMYAND
INVESTMENT
• It is predicted that energy efficiency in building
and appliances can reduce 1.6 Gt CO2 in 2020
and up to 7Gt CO2 in 2050.
• In terms of region, the fastest growing regional
green building market is Asia.
• Over 85% firms expect rapid or steady growth
in sales and profit levels associated with green
building.
• GB is a win – win situation for all stake holders:
developers, builders, policy makers and the
world as whole.

19. CONCLUSION
• With the convergence of urbanization,
globalization and rapidly changing and
expanding economy, using these energy
materials will help the world as well as India
in satisfying the shortage of building materials
and also environmental degradation.
• Green building will also provide tangible and
significant return on investment to contractors,
architects and building owners.
