  • Buildings consume a tremendous amount of resources for their use. Rapidly growing urbanization and increasing affordability of people has increased the construction activities. Buildings are major consumers of energy in their construction, operation and maintenance. Globally about 40% of energy is estimated to be in the building sector. This increasing demand has led to rapid consumption of conventional energy resources and environmental pollution. 03/21/13
  • The concept of green building aims at overcoming the energy crisis so that energy demands can meet the available resources. It promotes renewable energy to mitigate fossil fuel based energy requirements and also saving environment by minimum pollution in using and construction. 03/21/13
  • Reduction in the use of conventional energy resources, utilizing green energy, reducing waste and pollutants, water management are the factors which make a building green. 03/21/13

  • The common measures adopted for reducing the use of conventional energy include installing solar panels on the roof, optimum window to wall ratio, insulating walls by external shading and glazing to reduce heat transfer through walls, underground ducts and heat pumps for heating and cooling, using CFL (Compact Fluorescent Light bulbs) instead of ordinary bulbs, etc. 03/21/13
  • Effective water management can reduce the water requirement of a building up to 40%. Rain water harvesting systems can be used to collect water to be used for watering plants, washing cars and flushing toilets. Gray water from kitchen, sinks, baths and washing machine can also be used to flush lavatories. Low flow plumbing fixtures can reduce the water demand by 62%. Dual flush toilets help conserve water with controlled water outlet options. Use of native crops and vegetation reduces the irrigation demand. 03/21/13
  • Solar energy is most commonly utilized in the green buildings. Orientation of the building should be such that the maximum energy is harnessed. For large project wind mills can be installed on the roof to generate electricity. Solar panels for water heating can fulfill 100% hot water demand. 03/21/13
  • With the projected energy demand, thermal energy is not likely to be a solution and renewable energy can only meet the part of energy requirement. CPWD ensured griha compliance in all future govt. buildings. MNRE (Ministry of New and Renewable Energy) in association with TERI (The Energy and Resources Institute) founded ADaRSH (Association for Development and Research of Sustainable Habitats). It is an independent society for the interaction on scientific and administrative issues related to sustainable habitats in India, founded jointly by Government of India with experts in the domain of sustainability of built environment . ADaRSH promotes GRIHA (Green Rating for Integrated Habitat Assessment) as a design and evaluation tool for green buildings and habitats. IGBC formed LEED rating system to promote the concept of green building. 03/21/13
  • At present two rating systems are used in India- leadership in Energy and Environment Design LEED India and Green Rating for Integrated Habitat Assessment GRIHA. LEED was introduced by IGBC (Indian Green Building Council), which was created in 2001 as partner to UGBC (United States Green Building Council). It gives a rating of Platinum, gold, silver. Ministry of New and Renewable Energy MNRE in association with TERI The Energy Resources Institute developed GRIHA for promotion for energy efficient green buildings in India. GRIHA is an integrated framework for ensuring design, construction, operation and in turn rating of ECBC compliant green buildings. It gives a rating of one to five stars. 03/21/13

  • GRIHA rating system consists of 34 criteria categorized under various sections such as Site Selection and Site Planning, Conservation and efficient utilization of resources, Building operation and maintenance, and Innovation points. Eight of these 34 criteria are mandatory, four are partly mandatory, while the rest are optional. Each criterion has a number of points assigned to it. It means that a project intending to meet the criterion would qualify for the points. Different levels of certification (one star to five stars) are awarded based on the number of points earned. The minimum points required for certification is 50. 03/21/13
  • Online registration for GRIHA. Payment of fees by private projects/submission of undertaking by government projects. Orientation workshop by ADaRSH. Compliance on-site through site audit by ADaRSH. Online Submission of documents by project proponent. 1st evaluation of documentation by ADaRSH. Compliance of comments/observation on documentation by project proponent. 2nd evaluation by subject specific evaluators. If required, clarifications sought from client, based on evaluator's observation. 3rd evaluation by evaluators. Compilation of score by ADaRSH. Provisional Rating awarded by NAC (National Advisory Council). Performance audit/energy audit by BEE accredited auditor. Evaluation of audit report by ADaRSH. Award of final rating by NAC. 03/21/13

  • On a long term basis a green building proves out to be economical. It causes minimum harm to the environment and provides human comfort. The reduction in carbon emission, water use, energy use and waste are about 35, 40, 50 and 70 per cent respectively. 03/21/13

  • With a drastic increase in the demand of energy and environmental pollution, it has become imperative to take measures against it. The concept of green building helps in bridging the gap between demand and supply of non-renewable and scarce resources through cost-effective interventions. So far central Govt. and industry association have played a stronger role and now utility companies, regulatory commissions; energy service companies are beginning to asset their roles. The recent increase in the number of green buildings in India has brought a glimmer of hope in the development of green environment and better future. 03/21/13
