  • 1. GUIDED BY DR. ANIL AGARWAL SUBMITTED BY BHAGWAT NILESH (251046) GHUMARE ADITYA (251052) GOPLANI MUKESH (251053)
  • 2. INTRODUCTION  NEED  OBJECTIVE  SCOPE  METHODOLOGY
  • 3. BUILDING ENERGY RATING SYSTEM  Evaluation tool to measure the energy performance of building throughout its life.  It consists of - Assessment of energy performance - Issuance of energy rating certificate - Communication of information
  • 4. BUILDING ENERGY RATING SYSTEM RATING SYSTEMS’ ANATOMY It can be explained with five basic questions  What should be calculated in order to assess building energy efficiency?  How should it be calculated?  What should the building energy efficiency be compared to?  How should the rating scale be defined?  What information should the energy certificate include?
  • 5. PARAMETERS MEASURES TAKEN BEFORE CONSTRUCTION  Site selection  Soil and landscape conservation  Health and well being  Conservation and efficient utilization of energy and resources  Waste management.
  • 6. PARAMETERS MEASURES TAKEN DURING CONSTRUCTION  Soil and landscape conservation  Conservation and efficient utilization of energy and resources  Waste management  Health and well-being
  • 7. BUILDING ENERGY RATING SYSTEM IN INDIA  There are three primary building energy rating systems in India 1. GRIHA 2. IGBC 3. BEE
  • 8. GRIHA  Stands for Green Rating for Integrated Habitat Assessment  All buildings, except for industrial complexes which are in the design stage, are eligible for certification under GRIHA  It consists of 34 criteria categorized under various sections  Each criterion has a number of points assigned to it.  Different levels of certification (one star to five stars) are awarded based on the number of points earned
  • 9. IGBC  It stands for Indian Green Building Council IGBC which is part of CII- Sohrabji Godrej Green Business Centre, is actively involved in promoting the Green Building concept in India  It has developed following 4 rating systems 1. IGBC Green Homes 2. IGBC Green Factory Building 3. LEED India for New Construction 4. LEED India for Core and Shell
  • 10. IGBC GREEN HOMES  IGBC Green Homes is the first rating program developed in India, exclusively for the residential sector  designed for rating new residential buildings which broadly include two construction types 1. Dwellings where interiors are part of the project. 2. Dwellings where interiors are not part of the project
  • 11. IGBC GREEN HOMES  IGBC Green Homes addresses green features under the following categories: 1. Site Selection and Planning 2. Water Efficiency 3. Energy Efficiency 4. Materials 5. Indoor Environmental Quality 6. Innovation & Design Process
  • 12. IGBC GREEN FACTORY BUILDING  The IGBC Green Factory Building addresses both the new and existing factory buildings.  It addresses green features under the following categories: 1. Site Selection and Planning 2. Water Conservation 3. Energy Conservation 4. Material Conservation 5. Indoor Environment Quality and Occupational Health Innovation & Design Process
  • 13. LEED India NC  It stands for LEED India for new construction  It is rating system for New Commercial Construction and Major Renovation  The specific credits in the rating system provide guidelines for the design and construction of commercial buildings of all sizes  The intent of LEED India NC is to assist in the creation of high performance and environmentally sound commercial and institutional buildings.
  • 14. LEED INDIA CS  It is LEED INDIA FOR CORE AND SHELL PROJECTS  It provides a set of performance standards for certifying the design and construction phases of core and shell buildings  LEED-CS was developed to serve the speculative development market, in which project teams do not control all scopes of a whole building’s design and construction
  • 15. LEED INDIA CS  it rates for seven categories of building as 1. Sustainable Sites 2. Water Efficiency 3. Energy & Atmosphere 4. Materials & Resources 5. Indoor Environmental Quality 6. Innovation in Design 7. Regional Priority
  • 16. BEE  It is developed by Bureau of Energy Efficiency  It is a Star Rating program for buildings which is based on the actual performance of a building in terms of its specific energy usage in kwh/sq m/year  BEE has developed the Energy Conservation Building Code (ECBC) which provides minimum energy performance standards for energy efficient commercial buildings with a connected load of 100 kW and above
  • 17. ENERGY CONSERVATION BUILDING CODE (ECBC)  This code is developed under the provision of Energy Conservation Act 2001  The purpose of this code is to provide minimum requirements for the energy-efficient design and construction of buildings  It is proposed to make the ECBC mandatory for all new building that have a connected load of 500 kW or greater or a contract demand of 600 kVA or greater
  • 18. ENERGY CONSERVATION BUILDING CODE (ECBC)  ECBC has provisions for (a) Building envelopes, except for unconditioned storage spaces or warehouses, (b) Mechanical systems and equipment, including heating, ventilating, and air conditioning, (c) Service hot water heating, (d) Interior and exterior lighting, and (e) Electrical power and motors
  • 19. HOW TO MAKE EXISTING BUILDINGS ENERGY EFFICIENT? Following changes are required in building Minor changes:  Saving water  Saving power Major changes:  Solar thermal System  Photovoltaic cells
  • 20. CONCLUSION  Real estate constructions is largest energy consumer in India  There is need to check the energy performance of these construction  Building energy rating system comprises of a set of criteria covering various parameters related to design, construction and operation of a green building  It helps to improve energy performance of building  Effective building energy rating systems help to unlock energy saving potential and contribute to the goal of meeting future environmental challenges
  • 21. FURTHER STUDY  Detailed analysis of individual energy rating system  Comparison between rating system based on various parameters.  Study of Economic aspects of building energy rating systems  Site visits to energy rated buildings
