  • TERI – MNRE creates awareness on GRIHA, the National Green Building Rating System, in New Mumbai

    9 March 2009

    Two-day workshop attended by leading architects, corporate, institutes and govt. bodies

    With the aim to create awareness amongst stakeholders -- architects, corporate, institutes, and government, on sustainable green building practices in India, especially in terms of metro cities like Mumbai, a GRIHA Training Programme was organized in association with MNRE, CIDCO and the Indian Institute of Architects. The inauguration witnessed the presence of Dr Arun K Tripathi, Director of MNRE, Ms Mili Majumdar, Associate Director TERI, Dr Anjali Parasnis Fellow, TERI and Vice-Chairman & Managing Director of CIDCO Shri G S Gill (IAS).

    In the workshop it was deliberated that almost Forty per cent of global emissions are attributed to buildings and while India grows at a rapid pace, it is important to construct "green" buildings and efficiently tackle its waste for sustainable living. GRIHA (Green Rating for Integrated Habitat Assessment), developed by TERI, has been adopted by MNRE (Ministry of New and Renewable Energy), Government of India as an evaluation tool for measuring and rating a building's environmental performance. GRIHA integrates the country's varied climate and building practices.

    Speaking on the occasion, Dr Arun K Tripathi, Director, MNRE said, "The Ministry encourages widespread construction of energy efficient buildings in the country through a combination of financial and promotional incentives, and other support measures so as to save a substantial amount of electricity and other fossil fuels apart from having peak load shavings in cities and towns. The objective will be achieved by providing incentives to buildings rated for their performance under National Rating System being promoted by the Ministry and financial support for organizing workshops and seminars for potential users and for compilation and publishing of documents related to solar/ green buildings."

    GRIHA by its qualitative and quantitative assessment criteria, rates a building on the degree of its "greenness". The rating is presently being applied to new buildings "commercial, institutional and residential" of varied functions.

    The two-day workshop provided a comprehensive understanding of GRIHA "focusing on the criteria, compliance, documentation and appraisal formats. The forum successfully established a strong pool of architects, builders and organisations to use the rating system. The training programme discussed the criterion of certification, which is spread across the life cycle of the building" from inception to operation.

    Elaborating on the need of a India-specific rating system, Ms Mili Majumdar, Associate Director, TERI said, "Given the growth of the economy and the Indian population, building activities would continue at a high level. This could lock us into large consumption of energy unless we design and construct buildings that are energy efficient and conserve natural resources. The GRIHA system enables the assessment of buildings against the objective of resource efficiency"

    Vice-Chairman & Managing Director of CIDCO Shri G S Gill (IAS) while addressing the gathering said, "CIDCO's corporate mission is to plan and create environment-friendly, model urban settlements with full-fledged physical and social infrastructure to meet residential, commercial and industrial need of population at present and in the years to come. This workshop by TERI will further the cause of CIDCO's mission and will have an informed citizenry who are conscious towards environmental concerns."

    MNRE has devised an incentive programme for GRIHA-rated "green" buildings to encourage its use by the architects, design consultants and urban local bodies. This includes 90 per cent reimbursement of registration fee, rebate in property, awards to Municipal Corporation and Urban Local Body tax etc for projects at various levels.

    GRIHA rating system is applicable for air-conditioned, non air-conditioned and hybrid buildings with great importance to solar passive architecture to reduce the energy demand. GRIHA operates on a 100-point system. Each criterion has points assigned to it. A project intending to meet the criterion would qualify for the points. Different levels of certification (one star to five star) are awarded based on the number of points earned. The minimum points required for certification is 50. Buildings scoring 50-60 points, 61-70 points, 71-80 points, and 81-90 points will get one star, two stars, three stars and four stars, respectively. A building scoring 91-100 points will receive the maximum rating, which are five stars.

    To achieve sustainable working places and habitats in becoming "green" buildings, optimal utilisation of resources is important. GRIHA comprises of criterion, which address issues such as sustainable site planning, management of energy, water and waste, health and well being of occupants.
