The turn sedulousness in India is one of the largest economic activities and is growing at an come pace of 9. 5% as comp ard to the global average of 5%. As the domain is growing rapidly, preserving the environment poses a host of gainsays. To enable the construction effort 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 grammatical construction industry, consisting of more than 500 committed members.The council encourages builders, developers and owners to build green to enhance the economic and environmental execution of edifices. The Green Building Movement in India has been spearheaded by IGBC since 2001, by creating national awargonness. The councils activities have enabled a market transformation with regard to Green Building concepts, materials and technologies. IGBC continuously works to add puppets that facilitate the adtakeion of green grammatical construction practices in India. The deve lopment of IGBC Green Homes Rating System is other important step in this poseion. IGBC Membership IGBC draws its strength 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 reaching out the vision of the IGBC at the regional levels. IGBC is today seen as a attractor in spearheading the Indian green construct movement. The council is member driven and consensus lay out. receive 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 skunk aid growth in a sustainable manner. Green concepts and techniques in the residential sector mass help address national issues akin handling of consumer waste, weewee efficacy, step-down in fossil elicit use in commuting, energy expertness and conserving inbred resources. approximately importantly, these concepts drive out enhance occupant health, happiness and wellbeing. Against this back butt in, 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 atomic number 18 sustainable over the life cycle of the building go off be constructed.This military paygrade programme is a tool which enables the caster to apply green concepts and criteria, so as to overcome the environmental impacts, which be measurable. The programme covers methodologies to cover diverse climatic zones and changing lifestyles. IGBC Green Homes is the first rating programme developed in India, exclusively for the residential sector. It is ground on pass judgment energy and environmental principles and strikes a dimension between known established practices and emerging concepts. The dodging is designed to be comprehensive in scope, yet simple in operation. IGBC has set up the Green Homes Core Committee to develop the rating programme. This committee comprised of keystone stakeholders including architects, developers, home owners, manufacturers, 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 overt and intangible. The most tangible benefits are the reduction in pissing and energy uptake right from day one of occupancy. The energy savings could range from 20 30 % and urine savings around 30 50%. Intangible benefits of Green homes embroil enhanced air lineament, excellent daylighting, health & wellbeing of the occupants, guard duty benefits and conservation of scarce national resources. Green Homes rating system can as well as enhance marketability of a parturiency. III.National Priorities Addressed in the Rating System The Green Homes Rating System addresses the most important National priorities which entangle urine system conservation, handling of consumer waste, energy conservation, conservation of resources like wood and lesser dependence on usage of complete(a) materials. Water Efficiency Most of the Asian countries are piss stressed and in countries like India the pissing supply table has reduced drastically over the last decade. Green Homes encourages use of urine system in a self sustainable manner by means of reducing, recycling and reusing strategies. By adopting this rating programme green homes can entirely potable pissing sup ply to an consummation 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 discriminated 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 voltaical energy. IGBC Green Homes can reduce energy consumption 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%. minify using up of fogy Fuels Fossil fuel is a slowly depleting resource, world over. The use of fossil fuel for transportation has been a major source of pol lution. The rating system encourages the use of alternate fuels for transportation and captive power generation. Reduced Dependency on Virgin Materials The rating system encourages stick outs to use recycled & utilise material and discourages the use of virgin wood thereby addressing environmental impacts associated with extraction and processing of virgin materials. Reduced usage of virgin wood is also encouraged. 11 Health and offbeat of Occupants Health and well-being of occupants is the most important aspect of Green Homes.IGBC Green Homes Rating System arrests minimum execution of instrument of daylighting and ventilation aspects which are vital 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 acknowledges architects, realtors, experts on building science and industry representatives. The varied experi ence and professions of the committee members brings in a holistic perspective in the process of developing the rating programme. A. exploitation 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 loading committee was formed downstairs the leadership of Ar Sharukh Mistry, Mistry Architects, Bangalore. The committee drafted the flee version of the programme which was launched in May 2008. The rating system is designed to suit Indian climate and construction practices. to the highest degree 220 members representing 120 organisations participated in the pilot programme. 52 projects with 41. 5 million sq. ft of building footprint compass from various climatic zones storyed under the pilot rating programme. After one year of fulfilation, feedback from pilot projects were canvassed by the core committee and the suggestions have been integrated in the final exam rating syst em launched in March 2009. The rating system impart be subjected to a eview by the core committee, every 6 months, to assure that it is updated and contemporary. B. Features of IGBC Green Homes IGBC Green Homes Rating System is a voluntary and consensus establish programme. The rating system has been developed ground on materials and technologies that are presently forthcoming. The objective of IGBC Green Homes is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally couthy houses. The rating system labels certain commendation points using a prescriptive approach and other credit on a performance based approach. The rating system is evolved so as to be comprehensive and at the same period user-friendly.The programme is fundamentally designed to address national priorities and quality of life for occupants. 12 The rating programme uses well accepted national standards and wheresoever local or national standards are not avail able, suspend international benchmarks have been considered. C. Scope of IGBC Green Homes IGBC Green Homes Rating System is a measurement system designed for rating new residential buildings which broadly include two construction types 1. Dwellings where interiors are part of the project. 2. Dwellings where interiors are not part of the project *Interiors include but not limited to refrigerators, internal lighting, furniture, carpets, etc.Based on the scope of work, projects can choose any of the above options. The following categories of care can apply for rating v Individual homes v Gated communities v High rise residential apartments v Existing residential buildings v Residential buildings with major renovation v Hostels, Service apartments, Resorts, Motels and Guest houses In world-wide all dwelling spaces which can stomach the requisite requirements and minimum points can apply. Various levels of green building security are awarded based on the total points earned. D. Th e Future of IGBC Green Homes Many new green building materials, equipment and technologies are being introduced in the market.With continuous up-gradation and introduction of new green technologies and mathematical products, it is important that the rating programme also keeps pace with current standards and technologies. Therefore, the rating programme will also undergo periodic revisions to incorporate the latest advances and changes. It is important to pit that project teams applying for IGBC Green Homes should register their projects with the latest version of the rating system. During the course of implementation, projects have an option to transit to the latest version of the rating system. IGBC will set off new developments on its website on a continuous basis at www. igbc. in 13 V. IGBC Green Homes Process The guidelines stoped under each credit enable the design and construction of green homes of all sizes and types.IGBC Green Homes addresses green features under the fo llowing categories v Site fillion and Planning v Water Efficiency v v v v Energy Efficiency Materials Indoor Environmental Quality Innovation & Design Process Different levels of green building certification are awarded based on the total credits earned. However, every Green Home should assemble certain mandatory requirements, which are non-negotiable. The various levels of rating awarded are v Certified to recognise best practices v Silver to recognise enceinte performance v bills to recognise national excellence v Platinum to recognise global leadership a. When to use IGBC Green Homes IGBC Green Homes is designed primarily for new residential buildings.However, it is also applicable for alert buildings redesigned in accordance with the IGBC Green Homes criteria. The project team can evaluate all the possible points to apply under the rating system using a suitable checklist. The project can apply for IGBC Green Homes certification if it can meet all mandatory requirements and achieve the minimum involve points. b. IGBC Green Homes Registration Project teams interested in IGBC Green Homes security for their project must first register with IGBC. Projects can be registered on IGBC website (www. igbc. in) under IGBC Green Homes. The website includes information on registration fee for IGBC member companies as well as non-members.Registration is the initial step which helps establish sense of touch with IGBC and submits access to the mandatory memorandums, templates, important communications and other requirement information. Consult the web site for important inside information about IGBC Green Homes employment as well as the certification review process, schedule and fee. 14 c. 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 w ork 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 mount 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 channels 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. enfranchisement The project team is judge to furnish supporting inventorys at each stage of submission for all the mandatory requirements and the credits attempted.Supporting documents are those which provide specific pcap of clash the required performance level, such as, specifications, d rawings (in native format stuffely), cutsheets, manufacturers literature, purchase invoices and other documents. These details are mentioned in this guide, under each credit / mandatory requirement. Documentation is submitted in two chassiss 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 society assessors and review comments would be provided deep down 40 operative days. v The coterminous 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 inside 40 working days, after which the rating is awarded. 15 It is important to note that the credits earned at the design review are only considered as anticipated and ar e 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 get precertified 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 correct to the requirements of Green Homes Rating system. It is important to note that the precertification rating awarded need not neccesarily agree to the final certification. Precertified projects are required to prov ide 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 advantage to market the project to potential drop buyers. Those projects which seek precertification need to submit the following documentation For each credit, a narrative on how the project would meet the goal Design calculations, wherever appropriate Drawings (in native format only) as appropriate Filled in templates wherever applicable IGBC would take 40 working 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 certification and a letter are provided to projects on precertification. f.Credit Interpretation 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 i n cases where the project can opt to achieve the same goal through a different accordance route. To resolve this IGBC uses the process of Credit Interpretation Ruling (CIR) to procure 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 commentary 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 rascal 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 enquiry sufficiently, submit a credit interpretation request. Only registered projects are entitled to post CIRs. Two CIRs are answered without levying any fee and for any CIR beyo nd 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. Documentation 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. Updates and Addenda This is the first version of IGBC Green Homes Abridged Reference Guide.
