4. INTRODUCTION
After Industrial Revolution world witness
• incalculable technological achievements
• population growth
• corresponding increases in resource use
Side Effects
Results
• Straining the limits of the Earth’s ‘carrying capacity’.
ie. Ability to provide the resources required to sustain life while
retaining the capacity to regenerate and remain viable. 3
• Pollution
• landfill at capacity
• Toxic waste
• Global warming
• Resource scarcity
• Ozone depletion
• Deforestation

5. What is a GREEN BUILDING?
A structure and using process that is environmentally responsible &
resource efficient throughout a building’s life cycle ie. from siting to
design, construction, operation, maintenance, renovation and
demolition.
Green building – also known as sustainable or high performance
building increases the efficiency with which buildings and their sites use
and harvest energy, water, and materials.

6. Reduces overall built impact on human health and the natural
environment by:
• Efficiently using energy, water and other resources.
• Protecting occupant health and improving employee
productivity.
• Reducing waste, pollution and environment degradation.

Environmental Impact Reduction

7. Rules adopted by Green Buildings:
1. The greenest building is the building that
doesn't get built.
2. Every building should be as small as possible.
3. It doesn’t contribute to sprawl.

Environmental Impact Reduction

8. GOALS OF GREEN BUILDING
Siting and structure design efficiency
Energy efficiency
Water efficiency
Materials efficiency
Indoor environmental quality enhancement
Waste reduction

9. Siting and structure design efficiency

Why is it important?
 Foundation of any construction project is rooted in 2 stages:
i. Concept stage ii. Design stage
During all life-cycle stages of a construction project
• Concept stage minimize impact on cost & performance
• Design stage minimize impact on environment
Buildings are complex products of diverse materials &
components of various design variables to be decided at the
design stage
A variation of every design variable may affect the
environment during life-cycle stages

10. 10
How can we achieve it?
Materials & Elements : Should reflect, transmit & absorb
solar radiation
 Energy Utilization : Use renewable powers to:
• Reduce utility cost
• Environmental impacts of energy
production
 Location : Develop in pedestrian friendly to:
• promote healthy life styles
• alternate modes of transportation
 Surfaces : If low traffic, use porous paved to:
• assist onsite storm water infiltration
• reduce erosion

11. Energy efficiency
11
Why is it important?
 Aims to reduce energy consumption in :
 embodied energy to extract, process, transport
and install building materials
 operating energy to provide services such as
heating and power for equipment.
High-performance buildings use less operating energy.
Embodied energy has greater importance.
 Make up as much as 30% of the overall life cycle
energy consumption.

12. 12
How we can achieve it?
 Building Material :Wood instead of brick , concrete or
steel
 Orientation :Shade windows & roofs in summer
Maximize solar gain in winter
Effective Window placement
 Windows Insulation :High Efficient for building envelope
Barrier for conditioned space
 Energy Utilization :Renewable Powers like Solar, Hydro,
Wind ,Bio mass
 Design :Passive solar building design
Eg. Low-Energy Home

13. Water efficiency
13
Why it is important?
 Aims in
 Reduction of water consumption
 Protection of water quality
 Demands on supply exceed the ability of aquifer to
replenish itself
 Unnecessary wastage of water resources

14. 14
How can we achieve it?
 Facilities : To increase the dependence of existing water
 Recycling : Water treatment and Heating :
• improves water quality & energy efficiency
• reduces amount of water in circulation
 Fixtures : Use water conserving fixtures
Eg. Ultra low flush toilets , Low flow shower
heads
 Design : Landscaping plan:
•Native , water retaining , drought resistant
plants
Rainwater harvesting system for irrigation

15. Materials efficiency
15
Why is it important?
 Efficient use and reuse of material reduces
i. Environmental impact ii. Liable cost
How can we achieve it?
 Use non-toxic, reusable, renewable & recyclable materials
such as
i. Coal combustion products ii. Foundry sand
iii. Demolition debris in construction
 Should be extracted & manufactured locally to minimise
embedded energy in transportation
 Manufacturing in off-site & bringing to site will:
i. Minimize waste , noise &dust ii. Maximize recycling
iii. High quality elements iv. Better OHS management

16. Some materials used in Green construction
Wool Brick
• Wool + Seaweed Polymer+ Clay
• 37 % more strength
• Resistant for cold and wet
Solar Tiles
• Absorbs energy from sun
• Protect building
• Steady indoor temperature
Ecofriendly
• Use rapidly renewable
• Bamboo instead of steel
Sustainable Concrete
• Crushed glass , wood chip,
slag from steel industry
• Reduction in CO2 emission
Paper insulation
• From recycled newspapers
& cardboards
• Filled with chemical foam
• Insect & Fire resistant
Triple-Glazed Windows
• Super-efficient windows
• Stops :Heat to enter building
Direct sunlight

17. Indoor environmental quality
enhancement
17
We spend on average 90% of our time inside the buildings.
 Enhancing indoor air quality in building provide occupants,
a. comfort b. well-being c. productivity.
 Indoor air quality seeks to reduce
 volatile organic compounds (VOC)
 air impurities like microbial contaminants.
Why is it important?

18. 18
Materials : Materials emit few/no carcinogens ,
irritants, reproductive toxicants etc.
Moisture resisting : Resist biological contaminant growth by
• insulated & tightly sealed envelope
• ventilation to eliminate moisture from
indoor activities
Design : HVAC system with well designed envelope
for
i. Thermal quality ii.Lighting quality
iii. Energy performance
Flooring : Smooth surfaced wood instead of carpets to:
• prevent allergies due to dust
• absorption & release of moisture in air
How can we achieve it?

19. Waste reduction
19
 Aims to reduce waste of energy, water and materials
used during construction.
 Nearly 60% of India's waste comes from buildings.
 During construction phase , one goal should be to reduce
the amount of material going to landfills.
Why is it important?

20. 20
How can we achieve it?
 Materials : Wood is preferred :
• Light & easy to work , so easy enovation
• Extends useful life, thus reduces waste
 Design : Well designed buildings helps to:
• reduce amount of waste by occupants
• provide onsite solutions ,eg. compost
bin
 Deconstruction : After building’s useful life:
• demolish & haul it to landfills
• reclaim ‘waste’ to useful build materials
 Water Utilisation: Greywater is used for:
• subsurface irrigation
• non-potable purposes, Eg. Flushing

25. Indian Green Building Council
• The Indian Green Building Council (IGBC), was formed in the year 2001 by
Confederation of Indian Industry (CII). The vision of the council is to usher
in a green building movement in India and facilitate India to become one
of the global leaders in green buildings by 2015.
• With a modest beginning of 20,000 sq ft (1,900 m2). green built-up area in
the country in the year 2003, today more than 1053 green buildings ( as
on April 2011) with a built-up area of over 648,000,000 sq ft (60,200,000
m2). are being constructed all over India, of which 147 green buildings are
certified and fully functional
• LEED India for New Construction
• LEED India for Core and Shell
• IGBC Green Homes
• IGBC Green Factory Building
• IGBC Green SEZ
• IGBC Green Townships

27. CONCLUSION:
27
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.
