This document discusses the GRIHA rating system for evaluating the ecological performance of buildings in India over their lifecycle. It outlines 34 criteria across categories like site selection, construction practices, materials used, waste management, energy and water efficiency, and indoor environment quality. Achieving points across these criteria leads to GRIHA certification. The rating aims to minimize resource use, waste and ecological impact through principles like reduce, reuse and recycle. It emphasizes optimizing thermal comfort while integrating Indian codes and standards.

1. Why Rate Buildings ?
Buildings consume:
1. 40% Energy.....
2. 42% Water.......
3. 50% Raw materials …
(TERI Griha Manual Vol.1)

2. Building Activity contributes to :
1. 50% Air Pollution......
2. 42% Green House Gas....
3. 50% Water Pollution......
4. 48% Solid Waste Generated....
5. 50% CFC.....

3. We Architects and Engineers
Seem like some “Villains”.... :(
Following “Ratings” will make us less of so.. :):)
Ratings – evaluation Tool for Ecological
Perfomance through Life Cycle of a Building..

4. Ratings- What do they do?
1. Look at various parameters of
a)Design....b) Construction...c) Operation
2.Criterion with assigned Points
3.A project gets points...points add up...
4.Voluntary in nature...

5. Some other rating systems:
BREEAM:Building Establishments
Environmental Assessment Method.
One of the earliest developed in 1990 in UK.
CASBEE: Comprehensive Assessment System
for Building Environment Efficiency.
Developed in Japan 2001.

6. GB Tools: Green Building Tools developed by
International Framework committee of 25
countries . Developed in 1998 and constantly
updated
HK BEAM: Developed in1996 in Hong Kong
LEED: Leadership in Energy and Environmental
Design developed in US 1998.

7. GRIHA
Green Rating for Integrated Habitat Assessment.
Developed by TERI and endorsed by MNRE.

8. Salient points
GRIHA has been developed for the different
agro-climatic Zones of India.
Developed particularly for non-ac spaces or
partially ac building.
Evaluators are experts from different fields
connected to the buildings and are from
specific region where the building is situated

9. Stresses on optimization of visual and thermal
indoor comfort.
Integrates all relevant Indian Codes and
Standards to act as tools for implementation

10. Emphasis:
 Minimise -
-resource consumption
-waste generation
-overall ecological impact
 By Five R philosophy-
-Refuse
-Reduce
-Reuse
-Recycle
-Reinvent.

11. Broad categories:
 Site selection and Planning
 Building Planning and Construction
 Building Operation and Maintenance
 Innovation
(34 Criteria---for this presentation 19 criteria
taken up)

12. Criterion 2:

18. Criterion 3:
Soil Conservation:
Very important oft overlooked.
It takes 100 years for 25 mm of soil to form (Griha manual:Vol 2)
In India we have different types of soil, identify
them, study fertility, pH,saline levls.,
Store it at site...
Avoid carting fertile soil from elsewhere..

20. Check this site : http://ceds.org/esp.html gives
vary comprehensively cost incurred when soil
is left un-conserved.
Involve Landscape Architect from the beginning
of the design as well as all the time during
construction.
