Foreword from the Indian Green Building Council (IGBC)
India is experiencing phenomenal growth in urban population in the last few decades. As per 2011 census,
31% of India's total population resides in urban areas. It is estimated that by the year 2030, the urban
population would rise to 42% of the total population of the country. As a result, India is witnessing
tremendous growth in transportation sector and the share of private modes of transport such as
two-wheelers and four-wheelers is increasing exponentially. To increase the share of public transport,
many Indian cities are developing rail-based Mass Rapid Transit Systems (MRTS). Currently metro rail
system (a type of rail-based MRTS) are operational in 8 Indian cities, 7 more cities are developing metros
which are under different stages of construction and 23 more cities are planning to have metro rail system.
Similarly several cities are planning for mono rail and light rail systems which are under various stages of
development.
At present, Metro Rail authorities in India have many internal organisational policies in place to sustainably
manage environmental resources. Few such policies include Energy Management Policy, Environment
Policy, Waste Management Policy and Water Policy. However, there is a need to have a definitive &
voluntary standard for green design, construction and operation of metro rail projects.
Against this background, CII's Indian Green Building Council (IGBC) has launched 'IGBC Green Mass
Rapid Transit System (MRTS) Rating Version 1.0 Abridged Reference Guide. This rating system is a tool
to enable new rail-based MRTS to apply green concepts during design & construction, so as to further
reduce environmental impacts that are measurable. The overarching objective of IGBC Green MRTS
Rating is to ensure environmental sustainability, while enhancing commuter experience.

I. IGBC Green Mass Rapid Transit System (MRTS) Rating
CII's Indian Green Building Council (IGBC) has set up the IGBC Green MRTS Steering Committee
for developing a rating program to address environmental performance of new Rail-based Mass
Rapid Transit Systems. The committee comprises of key stakeholders including Ministry of Urban
Development, Metro Rail Authorities, General Consultants, Contractors, Technology Providers,
Metro Rail Operators and Green Building Consultants. The committee, with a diverse background
and knowledge has enriched the rating system both in its content and process.
The rating has taken a very holistic approach to sustainability. It has addressed site environment
management, integration of MRTS with other modes of transport, indoor environment & comfort and
resource efficiency.
II. Benefits of Green MRTS
By applying the green concepts in the design, construction & operation, the following additional
benefits are envisaged over conventional MRTS for the Environment, Metro Rail Authorities and
Commuters:
v Reduced dependency on private vehicles thereby minimising the environmental impacts
associated with the use of fossil fuels
v Integration with other modes of public transport thereby enhancing connectivity
v Enhanced station accessibility to improve first & last mile connectivity and achieve maximum
ridership
v Maximise resource efficiency
v Increased environmental awareness among commuters
v Enhanced commuting experience
III. Scope of IGBC Green MRTS Rating
All new rail-based MRTS projects can apply for IGBC Green MRTS Rating, if they meet all the
mandatory requirements and achieve the minimum required credit points.
List of rail-based MRTS projects applicable under IGBC Green MRTS Rating are as under:
v Metro Rail Systems
v Mono Rail Systems
The current version of IGBC Green MRTS Rating Version 1.0 Abridged Reference Guide is only
applicable for Metro Rail Systems. IGBC would release applicability guide of IGBC Green MRTS
Rating for Mono Rail systems at a later date.
Scope of IGBC Green MRTS Rating for Metro Rail systems include Elevated stations,
Underground stations, At grade stations and Viaduct / Tunnel.

For the purpose of rating, the project team has to define a clear site boundary which includes but not
limited to:
v Station building, Ancillary facilities, Parking, Hardscape / Softscape areas around station etc.
v Except for Property Development areas within station, other Property Development areas
outside / above stations are excluded from the scope of IGBC Green MRTS Rating.
IV. IGBC Green MRTS Rating – Overview and Process
IGBC Green MRTS Rating addresses green features under the following categories:
v Site Selection and Planning
v Water Efficiency
v Energy Efficiency
v Material Conservation
v Indoor Environment and Comfort
v Innovation in Design & Construction
a. Registration
Rail-based MRTS projects interested in IGBC Green MRTS Certification can register with the
Council. Projects can be registered on IGBC website (www.igbc.in) under 'IGBC Green MRTS
Rating'. The registration is the initial step which will help in establishing contact with IGBC and
provide access to several resources like abridged reference guide and templates.
b. Certification
To achieve the IGBC Green MRTS Rating, the project must satisfy all the mandatory
requirements and the minimum number of credit points.
The project team is expected to provide supporting documents at preliminary and final stage of
submission for all the mandatory requirements and the credits attempted.
The project needs to submit the following:
1. General information of project including
a. Project brief including station type, number of floors, area statement, details of green
features etc.,
b. General drawings (in PDF format only):
i. Metro Network Plan
ii. Station Site Plan
iii. Station Landscape Plan
iv. Floor Plans
v. Elevations
vi. Sections
vii. Parking Plan
viii. Photographs / Rendered views
2. Narratives and supporting documentation such as drawings, calculations (in excel sheets),
declarations / contract documents, purchase invoices, manufacturer cut-sheets / letters /
material test reports, etc., for each mandatory requirement / credit.
The necessary details are mentioned in this guide, under each mandatory requirement and
credit. Documentation is submitted in two phases – preliminary submission and final submission:
v The preliminary submission involves all those possible credits which are aspired by the
project team. After the preliminary submission, review is done by third party assessors and
review comments would be provided by IGBC within 30 working days.
v The next phase involves submission of clarifications to preliminary review queries and final
submission. This review will also be provided by IGBC within 30 working days, after which
the rating is awarded.
It is important to note that the mandatory requirements and credits earned at the preliminary
review are only considered as expected. These mandatory requirements and credits are not
awarded until the final documents are submitted, along with additional documents showing
implementation of design features. If there are changes in any 'expected credits' after
preliminary review, these changes need to be documented and resubmitted during the final
submission.
The threshold criteria for certification levels are as under:
c. Credit Interpretation Request (CIR)
In some instances the design team can face certain challenges in applying or interpreting
a mandatory requirement or a credit. It can also happen in cases where the project can opt
to achieve the same intent through a different compliance route.
To resolve this, the project may use the process of 'Credit Interpretation Request' for which IGBC
releases a 'ruling' to ensure that all rulings are consistent and applicable to other projects as well.
The following are the steps to be followed to raise a CIR:
v Consult the Abridged Reference Guide for description of the Credit Intent and Requirements.
v Review the intent of the Mandatory requirement / Credit and self-evaluate whether the project
satisfies the intent.
