“Modification of R.K. COLLEGE BUILDING to
improve rating as per guidelines of Green
Rating for Integrated Habitat Assessment
(GRIHA)”

3. Introduction to Green Building
• Definition:“A Green Building is one which uses less water, optimises
energy efficiency, conserves natural resources, generates less waste and
provides healthier spaces for occupants, as compared to a conventional
building.“
• Green Building refers to a structure and building process that is
environmentally responsible and resource-efficient throughout a building's
life-cycle: from sitting to design, construction, operation, maintenance,
renovation, and demolition. This requires close cooperation of the design
team, the architects, the engineers, and the client at all project stages. The
Green Building practice expands and complements the classical building
design concerns of economy, utility, durability, and comfort.

4. Introduction to Green Building
• “Green building is a sustainable or high
performance building.”
• It increases efficiently in use of energy, water,
and other resources.
• It Protects occupant health.
• It Reduces waste, pollution and energy
consumption.

5. Introduction to Green Building

6. Introduction to Green Building
Goals of Green Building:
• It includes environmental, economic, and social
benefits.
• However, modern sustainability initiatives call for an
integrated and synergistic design to both new
construction and in the retrofitting of existing
structures.
• It often emphasizes taking advantage of renewable
resources, e.g., using sunlight through passive solar,
active solar, and photovoltaic techniques and using
plants and trees through green roofs, rain gardens,
and reduction of rainwater run-off.

7. Introduction to Green Building
Economic benefits of Green building:
• A green building may cost more up front, but saves
through lower operating costs over the life of the
building.
• Some benefits, such as improving occupant health,
comfort, productivity, reducing pollution and landfill
waste are not easily quantified.
• Even with a tight budget, many green building
measures can be incorporated with minimal or zero
increased up-front costs and they can yield enormous
savings.

8. Methodology

9. Elements of Green Building

10. Rating systems and Councils
• Some of the Indian system for Green Building rating:
1) GRIHA: Green Rating for Integrated Habitat
Assessment
2)LEED-India: Leadership in Energy Environmental and
Design - India
3) BEE: Bureau of Energy Efficiency
• Some of the international counsel’s for Green Building:

6) GRIHA : Green Rating for Integrated Habitat Assessment

12. History of GRIHA
• The Energy and Resource Institute (TERI) conceived
GRIHA and developed it jointly with The Ministry of
New and Renewable Energy (MNRE), Govt. of India.
• GRIHA is a system developed for “Green Building
Evaluation”.
• It gives rating to a building as per its guidelines mainly
covering following aspects.
• Evaluation criteria though somehow differ for New
Construction and existing construction.
• In this project existing building is taken for evaluation
and rating is given as per GRIHA.

13. Introduction to GRIHA
• Any Building can be divided into 3 Types as per its life cycle.

14. Benefits of GRIHA
• Reduced energy consumption without sacrificing the
comfort levels
• Reduced destruction of natural areas, habitats, and
biodiversity, and reduced soil loss from erosion etc.
