Introduction
Green Building, also known as sustainable
building, is the practice of creating
structures and using processes that areenvironmentally responsible and resource-
efficient throughout a building's life-cycle

THIS IS NOT A GREEN
BUILDING !!!
A building which is constructed in an ecofriendly
environment cannot be called as a Green Building

o It is applicable to any type of buildings &
existing buildings
o Green buildings are designed to reduce the
overall impact of the built environment 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 environmental
degradation

Green building rating system
Leadership in Energy &
Environmental Design (LEED)-
is an internationally recognized green
building certification system, providing
third-party verification.
Developed by the U.S. Green building
council (USGBC)

9/32
Sustainable Sites
Reuse of existing buildings and the
preservation of the surrounding
environment.
Sediment and erosion control- reduce
negative impacts on water & air quality
Reduce site disturbance- Conserve
existing natural areas and restore
damaged areas
-

10/32
Alternative Transportation - Reduce
pollution and land developmentimpacts
Minimize Heat Island Effect
Light pollution reduction- Eliminatelight trespass from the building and
site
Urban redevelopment

Energy efficiency
Minimum Energy Performance -
minimum level of energy efficiency for
the base building and systems. E.g.
effective window placement
CFC Reduction in HVAC&R Equipment-Reduce ozone depletion.
-

12/32
Optimize Energy Performance-
increasing levels of energyperformance & to reduce
environmental impacts associated with
excessive energy use. E.g. UseENERGY STAR Qualified Products
On site renewable energy -to reduceenvironmental impacts associated with
fossil fuel energy use.E.g. solar & wind
power
-

13/32
Water efficiency
Rain water harvesting system- Optimize
ground water usage and increaseits
recharge
Water Efficient Landscaping- Limit or
eliminate the use of potable water for
landscape irrigation.
-
7/30/2019 2011 Green Building
14/32
Innovative Wastewater technologiesReduce generation of wastewater
and potable water demand
E.g. dual plumbing that recycles waste water
Water Use Reduction - reduce the burden onmunicipal water
supply and wastewater
systems.
E.g. water conserving fixturessuch as ultra-low flush toilets
and low-flow shower heads.
-

15/32
Materials efficiency
Storage & Collection of Recyclables-
reduction of waste generated by building
occupants
Building reuse - reduce environmentalimpacts of new buildings as they relate to
materials manufacturing and transport.
Construction Waste Management- Redirectreusable materials to appropriate sites.
-
7/30/2019 2011 Green Building
16/32
Resource Reuse- reduce demand for
virgin materials Regional Materials- Increase demand
for building materials and products that
are extracted and manufactured withinthe region
Recycled Content- products that
incorporate recycled content materials
-
7/30/2019 2011 Green Building
17/32
Rapidly Renewable Materials-
E.g. bamboo (because bamboo grows
quickly)
Certified Wood -Encourage
environmentally responsible forest
management.

Indoor environmental quality
Minimum IAQ Performance-
Establish minimum indoor
air quality (IAQ) performance.
Carbon Dioxide (CO2) Monitoring-
Ventilation Effectiveness-delivery andmixing of fresh air
E.g.properly designed Heating,Ventilation and Air- Conditioning(HVAC) system
-

19/32
Construction IAQ Management Plan- PreventIAQ problems resulting from theconstruction/renovation process
Indoor Chemical & Pollutant Source Control
.E.g. reducebuilding products
emit toxic gases,
such as Volatile
Organic Compound
(VOC) and formaldehyde

Benefits of Green Buildings They can reduce respiratory diseases
by 9-20%
They increase occupant performance
by 6-26%
Their occupants have 15% less
absenteeism compared to those in
other buildings

Conclusion
Technology needs to overweigh costfactor so that green buildings become
viable.
There is a large need of awareness oftechnology.
By the year 2050 it is estimated that
residential, commercial andinstitutional buildings will consume38%
of global energy and release 3800 mega
tones of carbon in the atmosphere.

Climate change by itself can also
precipitate larger energy demand as
people seek greater comfort levels in
more extreme conditions.
Its the need of the day for every new
construction to be a green building and
to modify the present buildings with itsfeatures
