green building ppt with a case study

1. GREEN BUILDING

2. WHAT IS GREEN BUILDING??
“ Green or sustainable building is the
practice of producing healthier and more
resource-effective examples of construction,
restoration, operation, maintenance, and
demolition.”

3. OBJECTIVES OF GREEN
BUILDING
1. Green Buildings are designed to reduce the overall impact on
human health and the natural environment by the following ways:
2. Using energy, water and other resources efficiently.
3. By reducing waste, pollution, and environmental degradation.

4. INDIAN GREEN BUILDING
COUNCIL
• The Indian Green Building Council (IGBC) was
formed in the year 2001 by Confederation of Indian
Industry (CII).
• The aim of the council is to bring green building
movement in India and facilitate India to become
one of the global leaders in green buildings by 2015.

5. Benefits of certification –
WHY LEED?
 lead to the transformation of the built
environment
 built as designed and perform as expected.
 have lower operating costs and increased asset
value
 healthy and comfortable for their occupants
 reduce waste sent to landfills
 conserve energy and water
 reduce harmful greenhouse gas emissions

13. WHY CIRCULAR?

14. Courtyards The courtyards act as "light wells,"
illuminating adjacent work areas. When
this light is not sufficient, sensors
trigger the deployment of efficient
electric lights. Dimmers automatically
control the illumination levels, turning
the lights off when they're unnecessary.
Also, occupancy sensors prevent a light
from being switched on at an unoccupied
workstation.

15. Roof Garden
Absorbing heat and
radiating it into the
building. This is
minimized through the
roof gardens covering
55% of the roof area.

16. Natural
Lighting
Natural light deflection systems
can direct light deep into the room and
ensure better natural lighting
provisions.

17. Reflective glass (mirror)
 This material will most significantly reduce
penetration of radiation from the reflecting
side to the non-reflecting side (penetration of
11-37% of total striking radiation).
 Such glazing is used in this building where it is
desirable to maintain eye contact with the
outside as well as to prevent penetration of
radiation and in areas where it is hot most days
of the year.

18. Usage of Light Glazing and Vision
Glazing
The double glazed glass will just
allow the diffused sunlight to
pass through and will radiate the
solar radiation back. It is located
in the western direction because
the suns rays is highly radiant
when it is setting.

19.  This consists of two sheets of glass with space in
between, sometimes filled with air or other gases, or
vacuum.
 Variations in thickness have a certain effect, up to a
certain limit, on the percentage of radiation allowed to
penetrate and on thermal conductance of the
composition.
 The main advantage of this type of cross-section is its
ability to reduce heat transfer from one pane to the
other, both by conduction and by radiation.

20. Use of Traditional
Jalli
Jallis or Lattice walls are used to
prevent glare and heat gain while
ensuring adequate day lighting
and views. The jalli, used in
many historic buildings such as
the Taj Mahal, gives definition
and an aesthetic appeal to a
space.

buildings

23. Wind System
Wind tower with evaporative cooling
A combination of sensible cooling in the
ground and evaporative cooling with the
flow of air induced by the wind tower
can be achieved by a configuration as
shown. The heat loss from air results in a
decreased air temperature, but no change
in the water vapour content of the air.

24. Achievements
The building boasts of lighting energy savings of 88 percent compared to an
electrically lit building of the same size.
Vegetation that was lost to the built area was replaced by gardens on 55 percent of
the roof area.
The building achieves a 35 percent reduction of municipally supplied potable
water, in part through the use of low-flush toilets and waterless urinals.
Thirty percent of users have shifted to alternative modes of transportation:
carpools, bicycles, and cars that run on liquefied petroleum gas, a low-polluting
alternative to conventional gasoline and diesel.
95 percent of the raw material was extracted or harvested locally.
An impressive 77 percent of the building materials use recycled content.
A waste management plan ensured that 96 percent of construction waste was
recycled.

25. CONCLUSION
Green building is a much better product as
compared to conventional homes. It's good for
your pocket book through much lower utility bills,
good for your employer since healthy homes save
on medical bills and sick leave, and you live with
the knowledge that you are helping the earth.
