MESSAGE ON WORLD
ENVIRONMENT DAY
The economic and financial turmoil sweeping
the globe is a true wake-up call, sounding an alarm about the need to improve
upon old patterns of growth and make a transition to a new era of greener,
cleaner development. The theme of this
year’s World Environment Day – “Your planet needs you” – is meant to inspire
all of us to do our part.
The Earth faces the grave threat of climate change. While all countries will suffer, the poor
will bear the brunt of the impact. But
we also have an opportunity to change course.
Crucial climate change talks will take place in
The world also needs a “Green New Deal”
focused on investing in renewable sources of energy, eco-friendly
infrastructure and energy efficiency. This will not only create jobs and spur
recovery but also help tackle global warming.
If we invest even part of the substantial new economic stimulus packages
in the green economy, we can turn today’s crisis into tomorrow’s sustainable
growth. Moreover, countries that make the transition to a low-carbon society
will reap more than significant environmental benefits; they will be
well-placed to share their new technology with others.
But our planet needs
more than just action by governments and corporations; it needs each of us.
Although individual decisions may seem small in the face of global threats and
trends, when billions of people join forces in common purpose we can make a
tremendous difference.
On this World
Environment Day, I encourage all people to take concrete steps toward making
the planet greener and cleaner. Switch off the lights. Take public
transportation. Recycle. Plant a tree. Clean up your local park. Hold
corporations responsible for their environmental practices. And urge your government
representatives to Seal the Deal in

1. The term ‘Eco-Housing’ comprises of
environmentally benign and energy efficient buildings, sustainable construction
practices, and healthy and productive indoor environment, with lower natural
resources use. Eco-Housing will save money by conserving electricity and water,
save time through low maintenance, improve health by reducing exposure to
synthetic chemicals, and help to preserve the environment in the process. They
are characterized here as homes that incorporate Alternative or Appropriate
Technology (e.g. solar heating) in order to greatly reduce energy consumption,
material use and water consumption. Solid waste management will also form a
part of this process. The figure below shows the concepts embedded in an
Eco-House
. “A Eco-caring/Green Building could be defined as
one, which
encompasses the use of clean energy,
renewable energy,
efficient use of water, use of
recycled or
recyclable materials and provides healthy
indoor air quality.”
The Eco-housing Assessment Criteria is applicable to residential
building/building complexes and single-family residences in Pune.
2. OVERVIEW
The Eco-Housing
assessment criteria have been developed to include a project in its fold. The
criteria are based on local environmental issues and has a checklist of
measures aimed at architects, builders, financial institutions, and homeowners.
Designed to serve as a performance assessment tool, the criteria helps quantify
the environmental achievement of the building and provides a meaningful
differentiation of buildings in the marketplace.
The voluntary
rating and certification system developed based on the assessment criteria will
help developers and architects design and evaluate the green quotient of new
residential projects. To determine the environmental performance of a building
the Eco-Housing assessment criteria is divided into eight broad categories. The
criteria is made up of both voluntary and mandatory measures. Every measure has
been assigned points depending on its impact on environment, and its relevance
to local conditions. Points can be earned by meeting the performance goal of
the criteria.

The Eco-housing
assessment criteria has a total of 88 measures. Only 27 of the 88 measures are
mandatory. The maximum achievable points are 1000 and the project has to get a
minimum of 500 points to qualify for Eco-Housing rating. The rating system is
based on the number of points earned. Greater the number of measures attempted
higher the rating.

3. USING THE ECO-HOUSING WEB
ASSESSMENT TOOL
The web based Eco-housing assessment tool
gives a user the flexibility to assess the eco- performance of a project and
gauge the rating a project would achieve based on the measures being attempted.
On registration the user can enlist one/multiple projects and use the tool to
understand the probable rating the project can achieve.
All 88 measures
along with the corresponding points and submittal requirements are listed in
the web tool. Points allocated to all the mandatory measures are marked with a
red check box. As the user highlights the check box of measures being
attempted the total score along with the rating achieved is displayed on top of
the page.
The web tool gives
the user an option of generating a project report. The report will indicate the
total number of points, the breakup of points achieved in each focus area and
list down pre-requisites not met. A detailed list of all the measures attempted
along with the corresponding submittal requirement (should be enclosed to show
compliance) will also form a part of the report. Developers will have the
option of sending the assessment report of the proposed Eco-housing project
directly to the urban local body for approval.

The water so collected / recharged shall as far as possible be used for
non-drinking and non-cooking purpose.
Provided
that when the rain water in exceptional circumstances will be utilized for
drinking and / or cooking purpose, it shall be ensured that proper filter
arrangement and the separate outlet for by passing the first rain-water has
been provided. Provided further that it will be ensured that for such use,
proper disinfectants and the water purification arrangements have been made.
The
Eco-housing program launched by Municipal Corporation of Greater
Mumbai (MCGM) promotes the adoption of environmentally friendly practices,
energy efficient products, and techniques by the construction industry.
Applicable to the housing sector, the
Eco-housing voluntary rating and certification mechanism will help quantify the
environmental performance of residential projects and will provide a meaningful
differentiation of buildings in the marketplace.
Conventional buildings have a significant
impact on resource use and environment during their lifetime.
On the other hand, Eco-housing incorporates
environmental considerations at every stage of building construction. It offer
financial benefits, environment, community and infrastructure benefits, and
benefits associated with health and increased productivity as compared to conventional
buildings
The MCGM Eco-housing program encourages
developers to adopt the Eco-housing assessment criteria to certify the
environmental performance achieved by their residential project.
The
Eco-housing assessmentcriteria have successfullyestablished a baseline for
greendesign practices. The criteriainclude measures that span thefollowing
focus areas

The
Eco-housing assessment criteria is adopted for Mumbai city with technical
assistance from United States Agency for International Development (USAID),
International Institute for Energy Conservation (IIEC) and Science and
Technology Park (STP).
The
criteria developed for both new and existing projects are applicable to
residential buildings/building complexes and single-family residences.
The criteria include a checklist of measures aimed at architects, builders, financial institutions, and homeowners. Measures in each category ensure resource conservation during the life cycle of the project. Every measure has a submittal requirement to ensure compliance and is assigned points depending on its impact on environment, and its relevance to local conditions.
Eco-Housing Certification
Process
The
Municipal Corporation of Greater Mumbai (MCGM) Administration will serve as the
apex body for the certification of Eco-housing projects. The Administrative and
Technical wing of the Eco-housing and Resource Conservation Cell (EHRCC) will
evaluate, verify, and rate Eco-housing projects.
The
Project/ schemes are required to be submitted at Administrative wing situated
at office of Ch.E. (D.P.) at head office.
On
preliminary scrutiny, and payment of the certification fees by the developer,
the proposal is forwarded to the Technical Wing of Eco-Housing Resource
Conservation Cell. Representatives of the Technical wing evaluate the documents
submitted during the different phases of construction. Site visits are
conducted during and on completion of construction to verify compliance before
the certificate is issued by MCGM.
Validity
of the Eco-housing certification granted by MCGM is for 5 years after which the
certification has to be renewed. Random checks will be carried out by the
Eco-Housing Technical Cell to ensure that the systems installed in the housing
complex are in working condition and are being maintained.
Eco-housing and Resource Conservation
Cell (EHRCC)
The
Eco-housing and Resource Conservation Cell (EHRCC) under the administrative
control of the Additional Municipal Commissioner is made up of two wings, the
Eco-housing Administrative Wing and the Eco-housing Technical wing.
Wing
located at MCGM Head Office and headed by Chief Engineer, Development Planning
Wing
will accept Eco-housing applications and undertake preliminary scrutiny of the
submitted documents
Eco-housing
Technical Wing
Wing
headed by Executive Engineer (Civil) and situated at Civic Training Institute
and Research Center (CTIRC), Borivali.
Technical
team will validate registered projects. Final recommendation for certification
will be based on verification of documents submitted and on-site inspections
Eco-Housing Incentives
The
Municipal Corporation of Greater Mumbai will offer incentives to both
developers and consumers implementing Eco-housing measures, subject to
receiving approval from state government.
Incentivization
in the form of rebate in development charges & assessment tax is
principally approved by the corporation. However the same will require
amendment to M.M.C. act and will require clearance from the state government.
Municipal Administration is following up the issue with state Government.
In
case of retrofit projects, the applicant shall submit occupation certificate of
the building to confirm its authenticity.
