CONCLUSION BACKGROUND WHAT IS GREEN BUILDING? A ‘green’ building is a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life. GOAL OF GREEN BUILDING To help to sustain the environment without disrupting the natural habitats around it To promote a better planet earth, and a better place for us all to live Reduce trash, pollution and degradation of environment. Create a sound indoor environment for living and working purpose. FEATURES WHICH CAN MAKE A BUILDING ‘GREEN’ Efficient use of energy, water and other resources Use of renewable energy, such as solar energy Pollution and waste reduction measures, and the enabling of re-use and recycling Good indoor environmental air quality Use of materials that are non-toxic, ethical and sustainable Creating resilient and flexible structures Consideration of the environment in design, construction and operation Consideration of the quality of life of occupants in design, construction and operation A design that enables adaptation to a changing environment BENEFITS OF GREEN BUILDING ENVIRONMENTAL BENEFITS: Reduce wastage of water Conserve and restore natural resources Improve air and water quality Enhance protect biodiversity and ecosystems ECONOMIC BENEFITS: Reduce operating costs Improve occupant productivity Create market for green product and services SOCIAL BENEFITS: Improve quality of life Minimize strain on local infrastructure Improve occupant health and comfort GREEN BUILDING RATING SYSTEM WHAT IS GREEN BUILDING RATING SYSTEM? A rating system can be defined as a set of prerequisites and requirements that a project team must fulfill in order to receive certification. TYPES OF RATING SYSTEM BREEAM- United Kingdom BEAM- Hong Kong LEED- United States EEWH- Taiwan Green globes- Canada GBCS- South Korea Green star- Australia CASBEE- Japan GRIHA- India INTRODUCTION OF GRIHA WHAT IS GRIHA? Name: GRIHA is an acronym for Green Rating for Integrated Habitat Assessment. Country: INDIA Established : 2007 GRIHA is a Sanskrit word meaning – ‘Abode’. A innovative tool for sustainable development by the united nations A tool for implementing renewable energy in the building sector by ‘The Climate Reality project’- an organization founded by Mr. Al Gore; and UNEP-SBCI has developed the “Common Carbon Metric” (kWhr/sq m/annum), for international building energy data collection -based on inputs from GRIHA (among others) There are three primary Rating systems in India: GRIHA (Green Rating for Integrated Habitat Assessment) Green Rating for Integrated Habitat Assessment (GRIHA) is India’s own rating system jointly developed by TERI and the Ministry of New and Renewable Energy, Government of India. IGBC (Indian Green Building Council) LEED is developed by the U.S. Green Building Council (USGBC), the organization promoting sustainability through Green Buildings. BEE (Bureau of Energy Efficiency) It has star based rating system: more stars mean more energy efficiency. BEE has developed the Energy Performance Index (EPI). The unit of Kilo watt hours per square meter per year is considered for rating the building and especially targets air conditioned and non-air conditioned office buildings. EVOLUTION OF GRIHA OBJECTIVE OF GRIHA Minimize a building’s resource consumption, waste generation, and overall ecological impact Evaluates the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’ Based on accepted energy and environmental principles, seeks to strike a balance between the established practices and emerging concepts Reduced energy consumption without sacrificing the comfort level Reduced destruction of natural areas, habitats, and biodiversity, and reduced soil loss from erosion etc. WHY CHOOSE GRIHA? Two rating systems in India: LEED India and GRIHA LEED-India adapted from United States Green Building Council’s (USGBC) is primarily based on per capita energy consumption in developed nations like the US which does not work in India since India’s per capita energy consumption is very low compared to developed nations. GRIHA is more suited to Indian climate. Also unlike LEED, it does not promote usage of certain products like glass and air-conditioning equipment. FIVE ‘R’ PHILOSOPHY Refuse: To blindly adopt international technologies, products, etc. Especially in substitutes are available. trends, materials, areas where local Reduce: The dependence on high energy products, systems, processes, etc. Reuse: Materials, products, traditional technologies so as to reduce the costs incurred in designing buildings. Recycle: All possible wastes generated from the building site, during construction, operation and demolition. Reinvent: Engineering systems, designs and practices such that India creates global examples that the world can follow rather than India following the international examples. GRIHA PROCEDURE ELIGIBILITY Except for industrial complexes, all buildings (offices, institutions, hotels, hospitals, housing complexes, etc.) in the pre-design/design stage are eligible for certification under GRIHA. ADaRSH (Association for Development and Research of Sustainable Habitats), GRIHA secretariat helps evaluate whether the project is eligible for rating or not. GRIHA PROCEDURE REGISTRATION PROCESS Building project may register (http://www.grihaindia.org) The registration process allows access to essential information related to rating such as: 1. Application forms 2. List of submissions 3. Score points 4. The weightage system 5. Online documentation through the GRIHA website GRIHA PROCEDURE GRIHA also provides one day training session for the registered projects which includes: Overview of the green building design Explanation of the rating system and criteria and points related to rating Online access to the rating tool Documentation process through use of online forms Evaluation process GRIHA PROCEDURE EVALUATION PROCESS 1. Pre documentation stage: A team from ADaRSH along with the client’s Integrated Design Team meet and determine the points being targeted by the project. 2. Post documentation stage: All necessary proof through documents for the points targeted under various criteria is submitted. Evaluation by third party regional evaluators. To determine the final rating that shall be awarded to the project. GRIHA PROCEDURE After the necessary documentation is uploaded, and systems commissioned on the site, the buildings are evaluated and rated in three-tier process. The preliminary evaluation is done by a team of experts from ADaRSH. Reviewing of the mandatory points and checking for compliance. The project is rejected if mandatory criteria are not complied with. Evaluation of the optional criteria and estimation of the total number of achievable points. All compliance documents are examined through the appraisal process as outlined by GRIHA. Evaluation report given to members of an evaluation committee: external experts in building and landscape design, lighting and HVAC design, renewable energy, water and waste management, and building materials. The members independently review and award points, a provisional GRIHA rating is awarded after evaluation of document is submitted. GRIHA RATING SYSTEM VARIANTS OF GRIHA SVAGRIHA FOR BUILDING AREA- 100-2499 sqm GRIHA FOR BUILDING AREA-2500-1,50,000 sqm GRIHA LD FOR BUILDING AREA-> 50 hectare site area GRIHA VERISON 2015 The latest version of GRIHA, GRIHA version 2015 (GRIHA V2015), was introduced in January 2015. The GRIHA V 2015 rating system consists of 31 criteria categorized under various sections such as Site Planning, Construction Management, Occupant Comfort and Wellbeing, Sustainable Building Materials, Performance Monitoring and Validation, and Innovation Eligibility All buildings, which are in the design stage and have built up area more than 2,500 m2, are eligible for certification under GRIHA. GRIHA RATING CRITERIA Criteria and their weightage GRIHA is a performance-oriented system where points are earned for meeting the design and performance intent of the criteria. Each criterion has certain points assigned to it. It means that a project demonstrating compliance with a criterion would achieve the associated points. GRIHA is a 100-point system consisting of some core 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 are 25. GRIHA RATING CRITERIA EVALUATED IN DIFFERENT STAGES Pre-construction stage (intra- and inter-site issues) Building planning and construction stages (issues of resource conservation and reduction in resource demand, resource utilization efficiency, resource recovery and reuse, and provisions for occupant health and well being). The prime 4 resources that are considered in this section are land, water, energy, air, and green cover. Building operation and maintenance stage (issues of operation and maintenance of building systems and processes, monitoring and recording of consumption, and occupant health and well being, and also issues that affect the global and local environment). GRIHA RATING CRITERIA GRIHA RATING CRITERIA GRIHA OVERVIEW The points assigned to different criteria is based on survey conducted to better reflect current resource priorities of India.
