3. Green Building In India
Construction Industry is growing
The platinum LEED (Leadership in Energy and
Environmental Design (LEED-INDIA) rating has
motivated
Sustainable site development
Water savings
Energy efficiency
Materials selection and
Indoor environmental quality
Construction Industry in India to go green way
IGBC-Headed by Stack holders, Architects,
Industries,Material Manufacturers etc. to promote
Green building in India
4. What is a Green Building
Eco friendly or ecological construction is
building a structure that is beneficial or non
harmful and is resource efficient.
Use of key resources like Energy, Materials,
Water and Land more efficiently.
Sustainability is the practice of being able to
continue the harvesting, extractions etc. with
minimal long –term efforts on environment and
natural resources.

36. Cost analysis of Green building
Initial cost of the Green building is higher than
conventional one.
Incremental cost will appear small when eco principles
are applied.
The incremental cost should be seen with reference to
life cycle costs.
The payback period of incremental costs of some Green
buildings is as shown:
