4. A Green building should create delight when entered, serenity and
health when occupied and regret when departed‟ – Perhaps this is
one of the most inspiring definitions of a Green building,
articulated in the book „Natural Capitalism‟.
The concept of green buildings is not as nascent as we think it is.
5. PRINCIPLES OF GREEN BUILDING
1. Minimize natural resource consumption (materials and
energy) throughout the total building life cycle.
2. Minimize pollution and environmental releases throughout
the total building life cycle.
3. Protect the ecological (natural) environment.
4. Create a healthy, comfortable, no hazardous space.
5. Incorporate quality, function, and performance consistent
with the objective of the Building.
6. POTENTIAL BENEFITS OF A GREEN
BUILDING
A green building project must have clear and measurable
benefits for the variety of stakeholders involved.
Protecting the environment is certainly one of the primary
benefits. More and more evidence demonstrates that other
benefits are possible and that these can provide additional
incentives for “building green,” such as: Reduced life-
cycle costs, including.
7. Continue…
Operating costs (energy, maintenance, repair); and
Renovation, demolition, disposal costs.
Reduced risk and liability (avoided costs).
A better building offering, including.
Energy efficiency.
Improved lighting.
Improved comfort. and
Healthier indoor environment.
Improved occupant productivity.
8. DEFINITION OF THE BUILDING LIFE-
CYCLE
The environmental assessment process begins with a
definition of the total building life cycle, The
environmental impacts of the building and all
components can be assessed in terms of the changes
that occur in the environment as a result of this total
sequence of activities.
9. LEED India – Indigenized Rating System for
India
Eco or green design principles are universal; it cannot
be one for USA, one for India and one for Japan. Most
of the green building rating systems touch on the same
chord – conservation of resources. But the LEED
rating system has turned out to be the most versatile
and robust.
10. The LEED India will follow the following standards:
NBC guidelines for:
Erosion & sedimentation control
Rain water harvesting
Safety for workmen during construction
Wild Life Institute of India, Dehradun to define endangered
species
Environmental Information System (ENVIS) for Wet lands
preservation
11. The five rating systems evaluated were:
1) Building Research Establishment's Environmental
Assessment Method (BREEAM)
2) Comprehensive Assessment System for Building
Environmental Efficiency (CASBEE)
3) GB Tool
4) Green Globes US and
5) LEED.
12. GREEN BUILDINGS ARE COSTLIER
Considerable research and analysis has been carried
out with regard to the cost impacts of a green
building. The cost could be slightly higher than a
conventional building. We knows, buildings would
last for a 50 years or 60 years or 100 years!. Over its
life cycle, the operating cost would work out to
80-85% while the incremental cost which is a onetime
cost is only 8-10 %.
13. GREEN BUILDINGS HAVE TO BE AIR-
CONDITIONED
Green building concepts and the LEED rating can be
applied for non-air conditioning buildings. It has been
applied on three such buildings in India viz., IGP
office, Gulbarga, the Royal Engineering College
Hyderabad and LIC office, Shimoga. This ensures that
the building is recognized for any of the other energy
efficiency measures incorporated, for example - the
envelop, lighting, roof insulation etc.
14. PEOPLE ARE ATTRACTED TOWARDS A
GREEN BUILDING
o Operational Savings: Green buildings consume at least 40-
50 % less energy and 20-30 % less water vis-à-vis a
conventional building. This comes at an incremental cost of
about 5-8 %. The incremental cost gets paid back in 3-5 years
time.
o Air Quality: Green buildings are always fresh and healthy.
Every green building will have to purge continuous fresh air to
meet the requirements. The green buildings use interior
materials with low volatile organic compound (VOC)
emissions.

16. THE FUTURE OF GREEN BUILDINGS
The green building movement has started to gain
momentum. These include rating systems to evaluate a
building‟s environmental performance, certification
programs for green building products, and the adoption of
green building standards and practices by recognized
standard-setting organizations.
17. CONCLUSION
Building system components include the building
envelope, heating and air
conditioning, lighting, plumbing, and ventilation. The
green building experiences in India have been exciting
and challenging as well. The green building
movement is here to stay for the benefit of
individuals, society and the country at large.
