1.0 LEED rating system
The LEED (Leadership in Energy and Environmental Design) Green Building Rating System™ is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. The LEED system has been developed for US Market by the US Green Building Council, a non-profit organization, based at Washington .
LEED provides a complete framework for assessing building performance and meeting sustainability goals. Based on well-founded scientific standards, LEED emphasizes state-of-the-art strategies for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. LEED recognizes achievements and promotes expertise in green building through a comprehensive system offering project certification, professional accreditation, training and practical resources.
Levels of Rating:
The following are the different levels of LEED rating awarded to projects:
*Total no. of Available points is 69

2.0 LEED-INDIA
Though the LEED rating system is developed for the US market, it is highly applicable for buildings across the world. Today, more than 13 countries are adapting the LEED rating system world-wide.
The Indian Green Building Council (IGBC) is taking a lead in adapting the LEED rating system to suit the Indian context. By and large, the LEED US is applicable to India , to a great extent.
CII-Godrej GBC has signed a license agreement with USGBC in November 2005. Under this agreement , CII-Godrej GBC would be the sole license holder to offer LEED rating programs in India .
With few minor modifications in LEED US , LEED India will be launched by the IGBC. Initially buildings registered in India will be rated by USGBC and subsequently by the IGBC
To steer and guide the LEED India activities, IGBC has constituted a dedicated steering committee representing all stakeholders, under the chairmanship of Mr C N Raghavendran, Architect, CRN & Associates and Member, Indian Green Building Council (IGBC) .
The different activities involved in the the evolution of LEED india will be carried out in two phases:
I Phase Activities[ 2004-2006] :
• CII-Godrej GBC will promote USGBC's LEED Rating in India
• Indigenise LEED programme for India and build infrastructure
• CII-Godrej GBC will offer LEED training in India
• US version of the LEED Accredited Professional exam to be administered in India
II Phase Activities[2005-2007]:
• CII-Godrej GBC will offer and administer LEED India
• Continue to offer LEED workshop programmes
• Administer LEED Accredited Professional examination based on LEED India

The following are the changes proposed in the existing LEED rating system:
3.0 Changes Proposed in LEED India :
The committee has proposed several changes including two new prerequisites and a few additional credits. The changes proposed are the following:
3.1 New Prerequisites
i) Emissions from Captive Power Generators
In general, all buildings in india have captive power generation facility. The emissions from these captive power plants can have a direct impact on the building occupants and the community. To facilitate strict adherence to CPCB specified emission levels , LEED-India proposes to introduce this requirement as a prerequisite.
ii) Safety
LEED US does not address safety as an issue since other building construction codes would cover this aspect to a large extent. LEED India proposes to incorporate safety as a prerequisite , both during construction and post occupancy to ensure that a Green Building is also a safe building.
3.2 New Credits
i) Potable Water Use Reduction
In the existing US based LEED rating , potable water use reduction by 20% would qualify for 1 point and 30% would qualify for 2 points. LEED India would award one more aditional point if the project demonstrates a saving of 40% and more.
ii) Potable Water Use Reduction for Air-Conditioning Applications
Air – conditioning being a major use of water for cooling tower make-up , LEED India proposes to recognise projects which would use recycled waste water for cooling tower make-up applications. Hence, it is suggested as follows:
• 1 point for up to 75% reduction in potable water use for A/c
• Additional 1 point for up to 100% reduction in potable water use for A/c
iii) Green Power
LEED – India Steering Committee proposes that the quantum of investment on renewable energy made by the building owners, anywhere in the country should be recognised and awarded a point.
iv) Cooling Towers
ASHRAE 90.1 stipulates that cooling towers in buildings be CTI (Cooling Tower Institute, USA ) Certified.
Cooling tower testing facility is available in India.
v) Low VOC Paints
As per the existing LEED requirements, low VOC paints are required to be used inside the building. LEED India proposes to stipulate use of low VOC paints for the exterior surfaces also.
vi) Development Density
Under LEED USA ,this credit intends to channelise development to areas where the infrastructure is already in place.
In the Indian scenario , the National priority is to move developments away from the existing infrastructural areas, since they are already over-burdened and saturated. Hence it is proposed to exclude this credit in the LEED India rating system.
vii) Alternative transportation, Parking capacity
LEED India proposes to introduce preferential parking space to eco-friendly two wheelers also in aditon to cars, which have not been addressed in LEED US along with environment friendly four wheelers. |
