Governance Knowledge CentrePromoted by Department of Administrative Reforms and Public GrievancesMinistry of Personnel, Public Grievances and PensionsGovernment of IndiaCase StudyEnvironmental SustainabilityGreen Rating for Integrated HabitatTRANSPARENCY AND ACCOUNTABILITYAssessmentAugust 2011EXECUTIVE SUMMARYGreen Rating for Integrated Habitat Assessment (GRIHA) is a Government of India (GoI) ratingsystem1 for green buildings developed by The Energy and Resources Institute (TERI) in2004;Later, in 2007, the Ministry of New and Renewable Energy (MNRE) collaborated withTERI to form an independent society called ADARSH to develop and implement GRIHA. Thesociety’s responsibilities are to register projects under GRIHA, and also to advocate andgenerate awareness on sustainable habitats in the Indian context. All registered institutional,commercial and residential buildings except industrial complexes are rated based on 34 criteriathrough the process of building designing, construction, operations and maintenance. It is theonly rating system that covers ventilated, air conditioned and non-air conditioned buildingsystems.Based on nationally accepted energy and environmental principles, this initiative supportsgreen sustainable habitats using minimum renewable electricity consumption, rain waterharvesting and recycled waste materials that costs lesser than a conventional building withoutharming the environment. The environmental principles are adapted to local conditions ofclimate, technology and buildability.In 2009, MNRE made it mandatory for all government ent buildings under Central Public WorksDepartment (CPWD) to be GRIHA compliant.GRIHA is a design evaluation system which rates the environmental performance of a buildingholistically over its entire life cycle, thereby providing a definitive standard for what constitutesa ‘green building’. GRIHA ensures compliance with Energy Conservation Building Code(ECBC), National Building Code 2005 (NBC), Environment Impact Assessment, Norms ofCentral Pollution Control Board (CPCB), Bureau of Indian standards and local byelawrequirements for Solar Water Heating and Rain Water Harvesting.A wide range of computation and simulation tools including DOE2, TRNSYS, ECOTECT,RADIANCE etc are used to assess the environmental and cost impact of the design decisions.1 A green building rating system is an evaluation tool that measures environmental performance of a building through its lifecycle. It usually comprises of a set of criteria covering various parameters related to design, construction and operation of agreen building. Each criterion has pre-assigned points and sets performance benchmarks and goals that are largelyquantifiable. A project is awarded points once if it fulfills the rating criteria. The points are added up and the final rating of aproject is decided. Rating systems call for independent third party evaluation of a project and different processes are put inplace to ensure a fair evaluation. Globally, green building rating systems are largely voluntary in nature and have beeninstrumental in raising awareness and popularizing green building designs.2Researched and documented byOneWorld Foundation India

The recycle process is challenging as the solid waste is not segregatedat source. Therefore, it is necessary for buildings to reduce their resource consumption andwaste generation. It must engage in effective waste management to reduce the impact of wasteon the environment. Following table provides a list of wastes generated from buildings:Site waste- Deforestation, excavated soil,blasted stone, rubbleConstruction- Metals, boxes/cans, brokenbricks, shuttering oilsSewage/Sullage-Wastes from household sinks,showers and baths but not toilets)Organic waste- peels, vegetables, fruitsRecyclable waste- Paper, glass, metalsNon-recyclable waste- demolitiondebris,plastics, synthetic fibresE waste-CDs, electronics, hardwareChemical waste- adhesives, paintsFigure 2 The little book of griha rating, teriBuildings in its stages from construction, operation and demolition consume resources in theform of energy, water, materials etc. and emit wastes either directly in the form of municipalwastes or indirectly as emissions from electricity generation. This realisation led to GRIHA’sevolution as a solution-provider; it attempts to minimise building’s resource consumption,waste generation, and overall ecological impact to certain nationally acceptable limits /benchmarks.Evaluators are selected based on TERI examinations and are authorized to evaluate theenvironmental performance of a building holistically over its entire life cycle, therebyproviding a definitive standard for what constitutes a ‘green building’. The rating system,based on accepted energy and environmental principles, attempts to strike a balance betweenthe established practices and emerging concepts, both at national and international level. Theguidelines are revised every three years to take into account the latest scientific developmentsduring this period.Green Buildings, in contrast to conventional buildings are environment friendly, money andenergy efficient. Under GRIHA, TERI considers welfare of construction workers, energyefficient strategies and greenest habitat lifestyles. Advantages of green buildings are as follows:4Researched and documented byOneWorld Foundation India

EvaluationAll projects are evaluated in two broad stages. The first is the pre-documentation stage/ predesignstage where ADARSH team along with the client’s Integrated Design Team discusstogether to determine the points targeted by the project (out of 100). The second is the postdocumentationstage where all documents are submitted and are evaluated by third partyevaluators to rate and award the project. The building is evaluated and rated in a three tierprocess:i) Preliminary evaluation: A team of experts from ADARSH reviews the mandatorypoints and checks for compliance and if not compliant, rejects the project. The nextstep is to evaluate the optional criteria and count the number of achievable points.They assess project documents for their correctness and appropriateness; and alsopaid for every criterion they assess.ii)Project report submittals to the Evaluation Committee: The report is sent to theEvaluation Committee comprising of experts in building, landscape and design forreview.iii)Awarding of points: The Evaluation Committee independently review and awardpoints to the project.C.

The minimum is 50. Buildings scoring 50 to 60 points, 61 to 70 points, 71 to 80 points,and 81 to 90 points will get one star, ‘two stars’, ‘three stars’ and ‘four stars’ respectively. Abuilding scoring 91 to 100 points will get the maximum rating five stars. The minimum pointsto qualify for GRIHA certification is 50 points.BENEFITSGreen Buildings are beneficial to the building owners, users and the community as a whole.The operational cost is reduced because renewable energy is used without compromising thehousehold’s level of comfort. Water demands are met through rain water harvesting process.Heating, Ventilation and Air condition systems are reduced in size to provide optimalperformance at local conditions. As a result, the capital cost also is reduced. ed. Keeping in mind ofbiodiversity and ecological balance, GRIHA supports minimization of deforestation and landerosion on site. Pollution and waste are controlled through recycling and reuse of energymechanisms. The above mentioned processes ensure health benefits with reduced water and airpollution. Moreover, green building owners get the image of being conscious and sensitive toenvironmental degradation. By getting their buildings rated under GRIHA, they arecontributing in maintaining biodiversity and protecting the earth from further damage.In effort to promote green designs, MNRE provides incentives to developers and users with aminimum project size of 2500 square metres. It reimburses of up to 90% of the registration feefor buildings under 5000 0 square metres area with minimum three star rating and for thosegetting four star rating over 5000 square metres area. For architects and design team complyingwith GRIHA benchmarks, they receive Rs 2, 50,000 for projects between 2500 to 5000 squaremetres es area; and Rs 5 lakhs for projects over 5000 square metres area.

Green designs, as promoted by GRIHAbenefits the building owner, user, and the society as a whole. GRIHA is a unique initiative as itsupports the integration of resource-efficient features in pre-design, site planning, buildingsystem design HVAC, construction, water and waste management, in selecting ecologicallysustainable materials and in providing indoor environmental quality. Following are the keylessons learned from this initiative:Integrated design approachThe ADARSH team uses an integrated approach in building and rating systems to reduceenvironmental footprint in all aspects: pre-construction state, planning and construction;operation and maintenance. The client, architect, engineers and consultants design buildingsbases on established environmental principles in a coordinated manner with a common goalwhich is sustainability.Complaint with national environmental and building codesGRIHA benchmarks are compliant with a wide range of building codes ECBC, NBC, BIS etc sothat both building systems and processes are well adapted to local Indian conditions of climateand technology.Optimum utlisation of ResourcesGRIHA supports sound architectural practices based on Indian’s traditional architecture. Ituses energy efficient technologies by adopting renewable energy sources. It utilizes locallyavailable construction materials to respond to local climate. It also refrains from wastingadditional building materials-water, electricity and natural resources thereby protectingenvironmental degradation.Promoting sustainable habitatsMonetary incentives and rebates on property tax are given to building owners, architects anddesign team for those who volunteer for GRIHA rating. Such incentives encourage builders toconstruct green designs and contribute to healthy ecosystem. The society also benefits fromGRIHA because it is an eco-friendly project that secures energy and resources through buildinggreen habitats.14Researched and documented byOneWorld Foundation India
