 OBJECTIVE AND METHODOLOGY
 LITERATURE REVIEW
 OVERVIEW OF ENERGY RATING SYSTEMS IN INDIA
 PARAMETERS OF ENERGY RATING SYSTEMS
 CASE STUDY- ENERGY RATING OF NICMAR PUNE
CAMPUS
 CONCLUSION AND SUGGESTIONS

3. OBJECTIVE AND
METHODOLOGY
 To understand the need of building energy rating
systems in India
 To study various types of building energy rating
systems available in India
 To study various parameters of building energy
rating assessment
 To carry out energy rating assessment of NICMAR
Pune campus
 Methodology adopted for this work is literature
review and case study analysis

4. LITERATURE REVIEW
 Main purpose is to find out the relevant information
about building energy rating systems in India
 Literatures were grouped under three aspects
1. Sustainable Building Construction
2. Parameters of Building Energy Assessment
3. Building Construction Energy Rating Policy in India
 It helped us to understand what is sustainable
building construction and its importance for India
 We found the different advantages of sustainable
construction over conventional construction

5. LITERATURE REVIEW
 Some literature has discussed about building energy
rating assessment and its parameters.
 We found advantages of building energy
assessment in order to improve energy performance
of building
 After study we came to know about different
policies of building energy rating in India
 We came to know about different initiatives taken
by Government of India to implement these policies
 Various energy rating agencies in India are providing
guidelines for energy rating of all types of building
construction
 These are GRIHA, IGBC and BEE

6. BUILDING ENERGY RATING
SYSTEMS IN INDIA
 Green Rating for Integrated Habitat Assessment(GRIHA)
 Indian Green Building Council(IGBC)
1. IGBC Green Homes
2. IGBC Green Factory Building
3. LEED India for New Construction
4. LEED India for Core and Shell
 Bureau of Energy Efficiency(BEE)

7. Energy Rating Systems for Different
Kinds of Buildings in India
Sr. No. RATING AGENCY BUILDING TYPE

1. Sustainable sites
2. Water efficiency
3. Energy efficiency
4. Material selection
5. Indoor environment quality
6. Environmental loading
7. Social and economical aspects
8. Cultural aspects
9. Service and quality

9. CASE STUDY
 Energy rating of NICMAR, Pune campus with respect
to energy rating systems available in India
 Building type: Institutional building
 Building area: 2,62,767 sq.ft.
 Climate zone: Hot and dry
 Energy rating is done with reference to
 GRIHA
 LEED India NC
 Energy rating cannot be done with BEE as it is limited
to office buildings and commercial spaces

10. CASE STUDY
 Methodology adopted for energy rating of NICMAR
Pune campus consists of main 3 steps
 Data collection
 Data analysis
 Result generation and conclusion

11. CASE STUDY-Data
Collection
 Data about NICMAR campus was collected by
study of official documents like architecture
drawings, electrical drawings, electricity bill etc.
 Other information was collected by site visit to
various areas of campus
 Data about energy rating systems and parameters
was collected by literature review
 All other information like energy assessment
procedure and points allocation was obtained by
official websites of these energy rating schemes

12. CASE STUDY- LIMITATIONS
 We found limitations to data collection to following
areas
 Quality certificate of construction materials
 Whether local construction material used
 Data about site condition during construction
 Air and water quality during construction
 Details of quality of workmanship during construction
 We have done necessary assumptions as required

13. CASE STUDY-Data Analysis
 Required data was collected as per provision of
rating systems
 The data was then analyzed as per the procedure
given in energy rating systems
 We have followed guidelines given by GRIHA and
LEED India NC
 We have compared the campus details with the
standards provided by above mentioned rating
systems
 Necessary assumptions were made wherever
required

14. Sustainable features of
NICMAR Pune campus
 Use of composite building envelope
 Use of open grid pavement
 Reduction of hard paving
 Use of solar water heating system
 Waste water treatment plant

15. Sustainable features need
to be adopted
 Innovative waste water technologies
 Use of high efficiency irrigation technology
 Use of onsite renewable energy technologies like
solar lighting
 Effective solid waste management systems
 Reduce water use through automatic flushing, low
flush fixtures and other similar tools
 Use of BEE rated equipments for energy use
reduction
 Adoption of rain water harvesting systems

17. CONCLUSION
 Sustainable building construction is need of
developing countries like India.
 Energy rating assessment is perfect tool to check
performance of sustainability of a building
 In India GRIHA, IGBC and BEE are prime three energy
rating tools available for building energy assessment
 All these systems mainly assess building parameters
like water efficiency, energy efficiency, waste
management, site sustainability and safety-health
aspect.
 Building energy rating promotes energy saving and
reduction in building waste

19. SUGGESTIONS
 Energy rating assessment should be based on actual
performance of a building.
 A periodic energy rating of buildings should be
made mandatory
 In Indian context solar energy utilization should be
given high priority while checking building energy
performance.
 All building documents should be properly
maintained by owner so as to facilitate energy
assessment
 Government initiative is required to promote
awareness about building energy rating
