INTRODUCTIONNEED

OBJECTIVE

SCOPE METHODOLOGY

BUILDING ENERGY RATING SYSTEMEvaluation 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

BUILDING ENERGY RATING SYSTEMRATING SYSTEMS’ ANATOMY

It can be explained with five basic questionsWhat 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?

PARAMETERS

MEASURES TAKEN BEFORE CONSTRUCTION

Site selectionSoil and landscape conservationHealth and well beingConservation and efficient utilization of

energy and resourcesWaste management.

BUILDING ENERGY RATING SYSTEM IN INDIAThere are three primary building energy rating systems in India

1. GRIHA2. IGBC3. BEE

GRIHAStands for Green Rating for Integrated Habitat

AssessmentAll 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

IGBCIt 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

IGBC GREEN HOMESIGBC 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

IGBC GREEN HOMESIGBC Green Homes addresses green features

under the following categories:1. Site Selection and Planning2. Water Efficiency3. Energy Efficiency4. Materials5. Indoor Environmental Quality6. Innovation & Design Process

IGBC GREEN FACTORY BUILDINGThe IGBC Green Factory Building

addresses both the new and existing factory buildings.

It addresses green features under the following categories:

1. Site Selection and Planning2. Water Conservation3. Energy Conservation4. Material Conservation5. Indoor Environment Quality and

Occupational Health Innovation & Design Process

LEED India NCIt stands for LEED India for new constructionIt is rating system for New Commercial

Construction and Major RenovationThe 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.

LEED INDIA CSIt is LEED INDIA FOR CORE AND SHELL

PROJECTSIt 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

LEED INDIA CSit rates for seven categories of building as1. Sustainable Sites2. Water Efficiency3. Energy & Atmosphere4. Materials & Resources5. Indoor Environmental Quality6. Innovation in Design7. Regional Priority

BEEIt is developed by Bureau of Energy EfficiencyIt 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

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

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

HOW TO MAKE EXISTING BUILDINGS ENERGY EFFICIENT?Following changes are required in building

Minor changes:Saving waterSaving powerMajor changes:Solar thermal SystemPhotovoltaic cells

CONCLUSIONReal estate constructions is largest energy

consumer in IndiaThere 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
