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
