The expression manufacturing in India is one of the largest economic activities and is emergence at an average rate of 9. 5% as compared to the global average of 5%. As the sector is growing rapidly, preserving the environment poses a host of challenges. To enable the face industry to be environmentally sensitive, CII-Sohrabji Godrej Green Business Centre has established the Indian Green Building Council (IGBC). IGBC is a consensus driven not-forprofit council representing the structure industry, consisti ng of more than 500 committed members.The council progresss builders, developers and owners to build one thousand to bring up the economic and environmental surgery of buildings. The Green Building transaction in India has been spearheaded by IGBC since 2001, by creating national awareness. The councils activities have enabled a market transformation with regard to Green Building concepts, materials and technologies. IGBC day-and-nightly works to go out tools that facilitate the ad election of green building practices in India. The development of IGBC Green Homes Rating System is another important step in this direction. IGBC Membership IGBC draws its distinctiveness from its members who have been partners in facilitating the Green Building Movement in India.The local chapters led by individual champions and committed members have been instrumental in stretchability out the vision of the IGBC at the regional levels. IGBC is today seen as a leader in spearheading the Indian green building movement. The council is member driven and consensus found. come to Indian Green Building Council C/o Confederation of Indian Industry CII Sohrabji Godrej Green Business Centre Survey No. 64, Kothaguda Post Near Kothaguda Cross Roads, R R District Hyderabad 500 032, India Ph +91 40 23112971-74 Fax +91 40 23112837 Email emailprotected in Web www. igbc. in 9 I. Introduction The housing sector in India is growing at a rapid pace and contributing immensely to the growth of the economy.This augurs well for the country and now there is an imminent need to introduce green concepts and techniques in this sector, which back end aid growth in a sustainable manner. Green concepts and techniques in the residential sector stack help address national issues like handling of sustainr waste, water efficiency, reduction in fossil fuel use in commuting, energy efficiency and conserving natural resources. Most importantly, these concepts digest enhance occupant health, happin ess and wellbeing. Against this background, Indian Green Building Council (IGBC) has launched IGBC Green Homes Rating System to address the national priorities. By applying IGBC Green Homes criteria, homes which are sustainable over the life cycle of the building substructure be constructed.This evaluate programme is a tool which enables the tendencyer to apply green concepts and criteria, so as to reduce the environmental impacts, which are measurable. The programme covers methodologies to cover diverse climatic zones and changing lifestyles. IGBC Green Homes is the first-year rating programme developed in India, exclusively for the residential sector. It is based on accepted energy and environmental principles and strikes a balance between know established practices and emerging concepts. The system is juted to be comprehensive in scope, yet honest in operation. IGBC has set up the Green Homes Core Committee to develop the rating programme. This committee comprised of key st akeholders including architects, developers, home owners, makers, institutions and industry representatives.The committee, with a diverse background and knowledge has enriched the rating system both in its content and process. 10 II. Benefits of Green Homes Green homes can have tremendous benefits, both tangible and intangible. The most tangible benefits are the reduction in water and energy white plague right from day one of occupancy. The energy nest egg could range from 20 30 % and water savings around 30 50%. intangible benefits of Green homes imply enhanced air quality, excellent daylighting, health & wellbeing of the occupants, safety benefits and conservation of scarce national resources. Green Homes rating system can also enhance marketability of a project. III.National Priorities Addressed in the Rating System The Green Homes Rating System addresses the most important National priorities which admit water conservation, handling of consumer waste, energy conservation, conservation of resources like wood and lesser dependence on usage of virgin materials. Water Efficiency Most of the Asian countries are water stressed and in countries like India the water instrument panel has reduced drastically over the last decade. Green Homes encourages use of water in a self sustainable manner through reducing, recycling and reusing strategies. By adopting this rating programme green homes can save potable water to an extent of 30 50%.Handling of House -hold Waste Handling of waste in residential buildings is extremely difficult as most of the waste generated is not segregated at source and has a high probability of going to land fills. This continues to be a challenge to the municipalities which needs to be addressed. IGBC intents to address this by encouraging green homes to segregate the house hold waste. Energy Efficiency The residential sector is a large consumer of electrical energy. IGBC Green Homes can reduce energy drug addiction through energy efficient lighting, air conditioning systems, motors, pumps etc. , The rating system encourages green homes which select and use BEE labeled equipment and appliances. The energy savings that can be realised by adopting this rating programme can be to the tune of 20 30%.Reduced Use of Fossil Fuels Fossil fuel is a slowly depleting resource, world over. The use of fossil fuel for transportation has been a major source of pollution. The rating system encourages the use of alternate fuels for transportation and mantled power generation. Reduced Dependency on Virgin Materials The rating system encourages projects to use recycled & reused material and discourages the use of virgin wood thereby addressing environmental impacts associated with source and processing of virgin materials. Reduced usage of virgin wood is also encouraged. 11 Health and Well-being of Occupants Health and well-being of occupants is the most important picture of Green Homes.IGBC Green Homes Rating System real ises minimum performance of daylighting and ventilation aspects which are critical in a home. The rating system recognises measures to minimise the indoor(a) air pollutants. IV. IGBC Green Homes Rating System IGBC has set up the Green Homes Core Committee to focus on residential sector. The committee includes architects, realtors, experts on building science and industry representatives. The varied experience and professions of the committee members brings in a holistic perspective in the process of developing the rating programme. A. Evolution of the Rating System IGBC, in its endeavor to extend green building concepts to all building types envisioned a rating programme for homes in December 2007.A heart committee was formed to a deject place the leadership of Ar Sharukh Mistry, Mistry Architects, Bangalore. The committee drafted the pilot reading material of the programme which was launched in May 2008. The rating system is forgeed to drive Indian climate and reflexion prac tices. About 220 members representing 120 organisations participated in the pilot programme. 52 projects with 41. 5 million sq. ft of building footprint field from non-homogeneous climatic zones registered under the pilot rating programme. After one year of implementation, feedback from pilot projects were recaped by the core committee and the suggestions have been hold backd in the final rating system launched in March 2009. The rating system will be subjected to a eview by the core committee, every 6 months, to ensure that it is updated and contemporary. B. Features of IGBC Green Homes IGBC Green Homes Rating System is a voluntary and consensus based programme. The rating system has been developed based on materials and technologies that are presently available. The objective of IGBC Green Homes is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally friendly houses.

IGBC Green Homes Certification Levels The rating system caters to projects like individual houses, apartments, motels, resorts, hostels, etc. , Amongst the different types, projects are broadly classified into two categories v Projects where interiors are part of scope of work v Projects where interiors are not part of the scope of work Interiors include but not limited to materials like interior finishes & furniture and appliances like refrigerators, fans, lights etc. As a general guideline, individual owners can use the checklist Projects with Interiors and developers & builders can use the checklist titled Projects without Interiors. However, if the context varies, projects can adopt the one which is the closest fit. The threshold criteria for certification levels are as under Certification Level Certified Silver Gold Platinum Points for projects with interiors 32 39 40 47 48 59 60 80 Points for projects without interiors 30 36 37 44 45 55 56 75 d. Documentation The project team is expected to provide supporting documents at each stage of submission for all the mandatory requirements and the credits attempted.Supporting documents are those which provide specific p jacket crown of meeting the required performance level, much(prenominal) as, specifications, drawings (in native format moreover), cutsheets, manufacturers literature, procure invoices and other documents. These details are mentioned in this guide, under each credit / mandatory requirement. Documentation is submitted in two phases design submittals and construction submittals v The design submission involves those credits which can be evaluated at the design stage. The reference guide provides the list of design and construction phase credits. After the design submission, review is done by third party assessors and review comments wo uld be provided within 40 working old age. v The next phase involves submission of clarifications to design queries and construction document submittal.The construction document is submitted on completion of the project. This review will also be provided within 40 working days, after which the rating is awarded. 15 It is important to note that the credits earned at the design review are lonesome(prenominal) considered as anticipated and are not awarded until the final construction documents are submitted along with additional documents showing implementation of design features. If there are changes for any design credit anticipated, these changes need to be documented and resubmitted for the construction review phase. IGBC will recognise homes that achieve one of the rating levels with a formal letter of certification and a mountable plaque. e.Precertification Projects by developers can register for Precertification. This is an option provided for projects aspiring to let precerti fied at the design stage. The documentation submitted for precertification must detail the project design features which will be implemented. The rating awarded under precertification is based on the projects intention to conform to the requirements of Green Homes Rating system. It is important to note that the precertification rating awarded need not neccesarily correspond to the final certification. Precertified projects are required to provide the status of the project to IGBC, in relation to the rating, once in every six months until the award of the final rating.Precertification gives the owner/developer a unique utility to market the project to potential buyers. Those projects which seek precertification need to submit the following documentation For each credit, a narrative on how the project would meet the aspiration Design calculations, wherever appropriate Drawings (in native format only) as appropriate Filled in templates wherever applicable IGBC would take 40 worki ng days to review the first set of precertification documents. On receiving the clarifications posed in the first review, IGBC would take another 40 working days to award the precertification. A surety and a letter are provided to projects on precertification. f.Credit meter reading Ruling In some instances the design team can face certain challenges in applying or interpreting a mandatory requirement or a credit. It can also happen in cases where the project can opt to achieve the same goal through a different compliance route. To resolve this IGBC uses the process of Credit Interpretation Ruling (CIR) to ensure that rulings are consistent and applicable to other projects as well. 16 The following are the steps to be followed in case the project team faces a problem v Consult the Reference Guide for exposition of the credit goal, compliance options and calculations. v Review the goal of the credit or mandatory requirement and self-evaluate whether the project satisfies the goal. Review the Credit Interpretation web page for previous CIR on the relevant credit or mandatory requirement. All projects registered under IGBC Green Homes will have access to this page. v If a similar CIR has not been addressed or does not answer the question sufficiently, submit a credit interpretation request. Only registered projects are qualified to military post CIRs. Two CIRs are answered without levying any fee and for any CIR beyond the first two CIRs, a fee is levied. g. Appeal Generally credits get denied due to misinterpretation of the goal. On receipt of the final review, the project team has the option to appeal to IGBC for reassessment of denied credits or mandatory requirements.The documentation for the mandatory requirements or credits seeking appeal may be resubmitted to IGBC along with necessary fee. IGBC will take 40 working days to review such documentation. These submissions would be reviewed by an assessor not involved in the earlier assessments. Documentati on for appeals should include the following i. Documentation submitted for design submission ii. Documentation submitted for construction submission iii. Clarifications along with necessary drawings and calculations VI. Fee Certification fee details can be found on IGBC website. VII.
