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 years 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 Copenhagen in December. Together, we must press governments to Seal the Deal for a new climate agreement.


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 todays crisis into tomorrows 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 Copenhagen.

The Municipal Corporation of Greater Mumbai (MCGM) is launching the Eco-housing program to encourage environment sensitive residential development in the city. The Eco-housing assessment criteria lists down a number of measures to help quantify the environmental performance of completed projects. The criteria is applicable to new construction as well as for the retrofit projects (existing housing societies). A voluntary five star rating and certification mechanism developed around the Eco-housing assessment criteria encourages adoption of energy efficient and resource conservation measures.

The Municipal Corporation of Greater Mumbai (MCGM) has established an effective monitoring and verification mechanism 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. Developers need to pay a fee for certification of their and can download the registration form to join the program

The Municipal Corporation of Greater Mumbai (MCGM) will offer incentives to both developers and end user to popularize the program

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.

 1.      SCOPE

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.



Site Planning


Environment Architecture


Efficient Building Materials


Energy Efficient Lighting


Solar Water Heaters


Water Conservation


Solid Waste Management


Other Innovative measures


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.


Focus Area



501 600

601 700

701 800



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 main objectives of this initiative in the first year are

  • To establish baselines for Eco-Housing practices
  • Support the formation of eco-friendly financing packages
  • Showcase a model Eco-Housing residential sector project.

The subsequent objectives of this initiative is to develop a long term plan for partnering with other organizations, to build capacity of architects and developers so as to support entrepreneurship in Eco-Housing.

The objectives will be achieved by:

  • Creating an enabling environment for Eco-Housing through strategic stakeholder partnerships on the supply and demand side of the housing and finance market,
  • Capturing the benefits of Eco-Housing designs and financial mechanisms by integration into a demonstration project, and
  • A time-bound scale-up and mainstreaming plan with adequate financial institutional support.

Proposed Interventions

The interventions proposed by the mainstreaming partnership are both strategic and tactical to achieve the goals and objectives of the program. The technical approach describes how the partnership proposed to implement the interventions. The proposed approach aims at achieving the following subtle but important changes in the Indian market mindset.

  • Demonstrating sustainability credentials for housing for first mover planning authorities and mortgage financing institutions 
  • Demonstrating green credentials to investors helps to minimize investment risk and increase the appeal to ethical investors by getting them to demand such quality housing
  • Demonstrating superior environmental design to customers, resulting in reduced running and maintenance cost, healthy environment, and access to local amenities.

The key interventions and the proposed approach are listed below

  • Engagement of Stakeholders Professionals with varied expertise in the Building industry
  • Development of Eco-Housing Performance Assessment Tools A user-friendly software tool to facilitate the assessment of Eco-Housing attributes.

MCGM Eco-housing Program

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.

आग का गोला बन जाएगी धरतीApplicable 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.

Eco-Housing Assessment Criteria

The Eco-housing assessmentcriteria have successfullyestablished a baseline for greendesign practices. The criteriainclude measures that span thefollowing focus areas

Site Selection

Environment Architecture

Efficient Building Materials

Energy Conservation &Management

Water Conservation

Segregation of Waste

Other Innovative Measure

Eco-Housing Assessment Criteria

Eco-housing Assessment Criteria

Applicable for both new and existing residential projects

Developed into a voluntary star rating and certification system

Criteria is made up of a combination of voluntary and mandatory measures

For New Buildings

A minimum of 500 points out of 1000 points required to qualify for Eco-housing certification

For Retrofit Buildings

A 600 point system that incorporates 83 measures

A minimum of 150 points out of 600 points required to qualify for Eco-housing certification

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.

Eco-housing Administrative 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.
