2. INTRODUCTION
2
• A key architectural concept of the 21st century
• A technique of construction to make structure
environmentally sustainable
• An opportunity to use the resources efficiently
• Creates healthier buildings

3. ELEMENTS OF A GREEN CONSTRUCTION
3
1. Sustainable Site Design
2. Water Quality and Conservation
3. Energy and Environment
4. Indoor Environmental Quality
5. Materials and Resources

4. BENEFITS OF GREEN BUILDINGS
4
The benefits of green buildings can be grouped within
three categories:
1. Environmental Benefits
2. Economic Benefits
3. Social Benefits

5. 1. ENVIRONMENTAL BENEFITS
5
• Emission reduction
• Water conservation
• Better air quality
• Temperature moderation
• Waste reduction
• Increase biodiversity

6. 2. ECONOMICAL BENEFITS
6
• Energy and water savings
• Lower utility demand
• Reduced building costs
• Increased property values
• lower construction costs
• Job creation

7. 3. SOCIAL BENEFITS
7
• Improved health and productivity
• Improved quality of life
• Improved performance at offices
• Better sustainable conscience

8. GREEN BUILDING RATING
8
• A green building rating system is a tool that evaluates the performance of a
building and its impact on the environment.
• In India, there are predominantly three rating systems :
1) Leadership in Energy and Environmental Design (LEED)
2) the rating systems from Indian Green Building Council (IGBC)
3) the Green Rating for Integrated Habitat Assessment (GRIHA)

9. GRIHA Rating System
9
• GRIHA is a rating tool that helps people assesses the performance of
their building against certain nationally acceptable benchmarks.
• It evaluates the environmental performance of a building over its
entire life cycle.

10. GRIHA Criteria
• GRIHA rating system consists of 34 criteria categorized in four different
sections.
1. Site selection and site planning
2. Conservation and efficient utilization of resources
3. Building operation and maintenance
4. Innovation

11. 11
Points achieved GRIHA Rating
50-60
61-70
71-80
81-90
91-100
Table1: Rating Threshold
• GRIHA is a 100-point system consisting of some
core points, which are mandatory, while the rest
are optional.
• The rating criterion of GRIHA is shown in Table 1

21. CONCLUSION
21
• Green Buildings are environmental friendly as they help in resource conservation.
• Though the initial cost of construction is higher but it proves to be economical in long
run.
• Waste is minimized at every stage during the construction and operation.
• Green buildings increases the efficiency with which buildings and their sites use and
harvest energy, water and material
• The Green building concept is gaining importance in various countries, including India.
