This document summarizes a study analyzing energy rating systems for real estate projects in India. It includes an introduction, literature review on energy rating parameters and systems in India, an overview of the main energy rating organizations (GRIHA, IGBC, BEE), case study analysis of the energy rating of NICMAR Pune campus based on GRIHA and LEED standards, and conclusions/suggestions. The case study found that the NICMAR campus did not meet certification standards due to opportunities for improving energy efficiency and sustainable features. Overall, the study assessed that energy rating is important for promoting sustainable building and reducing energy use in India.
Study and analysis of energy rating of real
- 1. STUDY AND ANALYSIS OF ENERGY RATING OF REAL ESTATE PROJECTS IN INDIA GUIDED BY DR. ANIL AGARWAL SUBMITTED BY ADITYA GHUMARE PGD-ACM NICMAR, PUNE NICMAR, PUNE 2011-13
- 2. CONTENTS 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 GRIHA 1. commercial Buildings 2. Institutional Buildings 3. residential Buildings 2 IGBC Green Homes Residential Buildings 3 LEED INDIA NC 1.Office building 2.Retail and service building 3.Institutional Building 4 LEED INDIA CS 1. Office Buildings 2. IT parks 3. Warehouses 4. Retail centers 5 BEE 1. Office Buildings 2. IT parks
- 8. PARAMETERS FOR ENERGY RATING OF BUILDINGS 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
- 16. CASE STUDY-Results RATING AGENCY MAXIMUM POINTS MINIMUM REQUIRED POINTS FOR NICMAR PUNE CAMPUS GRIHA 104 50 47 IGBC LEED NC 69 26 25 NICMAR Pune campus could not get certified with both the systems for energy efficiency as per our analysis
- 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
