GRIHA - GREEN RATINGFOR INTEGRATED HABITAT ASSESSMENT

Endorsed by the Ministry of New and Renewable Energy, Government of India as of November 1 2007, GRIHA is a five star rating system for

green buildings which emphasises on passive solar techniques for optimizing indoor visual and thermal comfort. In order to address energy

efficiency, GRIHA encourages optimization of building design to reduce conventional energy demand and further optimize energy performance

of the building within specified comfort limits. A building is assessed on its predicted performance over its entire life cycle from inception

through operation.

It is a rating tool that helps people assess the performance of their building against certain nationally acceptable benchmarks. It has been

conceived by TERI and developed jointly with the Ministry of New and Renewable Energy, Government of India. It is a green building Design

Evaluation System, and is suitable for all kinds of buildings in different climatic zones of the country.

GRIHA was developed as an indigenous building rating system, particularly to address and assess non-air conditioned or partially air

conditioned buildings.

The rating applies to new building stockcommercial, institutional, and residential of varied functions.

GRIHA integrates all relevant Indian codes and standards for buildings and acts as a tool to facilitate implementation of the same.

Some of the key additional features that GRIHA requires are:

- Basic codes and norms prescribed by Indian standards such as the National Building Code (NBC), Energy Conservation Building Code (ECBC) and

Bureau of Indian Standards (BIS)

- Adherence to Central Pollution Control Board (CPCB) and NBC guidelines for acceptable outdoo and indoor noise levels.

- Minimum level ofsanitation/safety facilities for construction workers.

- Minimum natural day lighting requirements as per the NBC

- Minimum artificial lighting requirements as per the ECBC

- Urban context consideration

- Focus on non-air conditioned buildings

- Mandatory minimum requirement for solar energy: 1 per cent of the total energy needs for the development to be sourced from solar power

THREE STAR CERTIFICATION PROGRAM, CHINA

Chinas Three-Star certification program is an integral part of the national Green Building Evaluation Standard (GBES), which defines green

buildings as

buildings that save a maximum amount of resources (including energy, land, water, and materials), protect the environment, reduce

pollution, provide healthy, comfortable and efficient space for people, and exist harmoniously with nature throughout their lifecycle.

3-star system is run by the Ministry of Housing and Urban Affairs (MOHURD)

The China three-Star program is a national standard but offers provincial flexibility. Some provincial-level authorities in China have enacted

provincial GBES as adapted versions of the national GBES. (Provincial Flexibility)

MOHURD central office in Beijing, China is the only agency authorized to grant Three-Star status to buildings,

whereas local offices are authorized to certify One- and Two-Star buildings.

Chinese Three-Star Green Building Certification program, which started in 2006, has seen significant growth. Experts estimate that China now

has roughly 242 buildings certified at the Three-Star (highest) level of that program.

Local standards vary in the operational definitions of green buildings, but

they still agree upon the conceptual definition of green buildings, as

defined by the China GBES

Regular assessment indicators for buildings, can vary from 39 to as

much as 71

TERI-GRIHA

Teri-Griha is a rating system for greenbuildings which emphasises on passive solartechniques for optimizing indoor visual andthermal comfort rating applies to newbuilding stockscommercial, institutional,and residential of varied functions.

Endorsed by the Ministry of New and

Renewable Energy, Government of India asof November 1 2007, GRIHA is a five starrating system.

Griha is a national rating system thathelpsto assess the performance of the buildingagainst certain nationally acceptablebenchmarks and is mainly applied to green

buildings which emphasize on passive solartechniques for optimizing indoor visual andthermal comfort.

Chinas Three-Star certification program isan integral part of the national GreenBuilding Evaluation Standard (GBES), whichdefines green buildings as the following :

buildings that save a maximum amount of resources

(including energy, land, water, and materials), protectthe environment, reduce pollution, provide healthy,comfortable and efficient space for people, and exist

harmoniously with naturethroughout their lifecycle.

Control items are prerequisites, general items are the credits and preference are the strategic.


POINT ALLOCATION

GRIHA has a 100 point system consisting of some core points, which are

mandatory to be met while the rest are optional points, which can be

earned by complying with the commitment of the criterion for which

the point is allocated.

Different levels of certification (one star to five stars) are awarded

based on percentage of points earned. The minimum percentage

required for certification is 50. Buildings scoring 5060 percentagepoints, 6170 percentage points, 7180 percentage points, and 8190

percentage points will get one star, two stars, three stars, and four stars,

respectively. A building scoring 91100 percentage points will receive

the maximum rating, which is five stars.

ENERGY SAVING AND ENERGY UTILIZATION

Energy efficient appliances to be used

Energy recovery system to be used.(residential)

* As Energy consumption involves converting one energy

system to another so, Energy recovery systems harvest the

output energy and provide this as input power to the same

or another process.

e.g. Steel mill- Heated cooling water from the process is

sold for heating of homes, shops and offices in the

surrounding area building with a central heating or air-conditioning system

shall be equipped with room temperature regulating and

heat quantity metering facilities.(residential)

An electric boiler or electric water heater shall not be

used as the heat source of a heating or air-conditioning

system.(public)

ENERGY: END USE | ENERGY: RENEWABLE

Daylighting is given more importance than

artificial lighting or any other energy efficientappliance used.

Use of pre-cast systems to reduce energy

consumption on site.

Use of fly-ash in building construction (reduction

in energy in production of materials)

Both the rating systems give credit to optimization of building design to reduce load on energy.

Both of them provide special emphasis on the use of renewable energies.
