Ministry of New and Renewable Energy, GoI GRIHA Presented at Green School Design conference on sustainable design practices for schools in India Hanifl Centre for Outdoor Studies, Woodstock School, Mussorie, 16 th, 17 th April 2010
About TERI Approximately 800 professionals Scientists & researchers Economists Architects Engineers Plant bio-technologists Social scientists Urban and rural planners Agricultural scientists Energy experts Power engineers Water and sanitation engineers Industrial energy experts Renewable energy experts Solar photovoltaic, hydro power, solar thermal, wind, biomass, biogas
How it started since 1980 Vast experience in Renewable Energy Technologies, Water Resource Planning & Management, Rural Extension Activities, pollution control, Economics and econometrics Active role in policy related research (formulation, modification, upgradation, etc.) Experience through energy audits Audited buildings across the five broad climate zones of India Commercial Institutional Residential (multi-family) Government / offices Over 15 years of data collected Exhaustive research on passive architectural design Expertise in building energy simulations for visual / thermal comfort
As for green buildings Some jargon CRSBS - Centre for Research on Sustainable Building Science (Est. 2000) GRIHA Green Rating for Integrated Habitat Assessment (Est. 2005) ADaRSH Association for Development and Research of Sustainable Habitats (Est. 2010) ECBC Energy Conservation Building Code BEE Bureau of Energy Efficiency NBC National Building Code A/E/C Archtiectural / Engineering / Consultancy
TERI s s experience A little Over 100 buildings audited Over 100 new buildings offered consultancy on Large and small scale projects In varied climatic settings With different A/E/C teams across the country Policy related research and formulation (national and regional)
National (enabling) frameworks Existing codes National Building Code, 2005, other IS codes At the policy level, slow but steady additions Energy Conservation Act, 2001 Bureau of Energy Efficiency established Development of ECBC Designated consumers defined Examination for certified energy auditors and managers Electricity Act, 2003 Unbundling of the electricity sector to Reduce AT&C losses Improve performance and quality Competitive pricing Integrated Energy Policy, 2006 Looked at all aspects of energy consumption in the Indian economy, including small scale / rural energy issues
Moving towards net zero energy building BEE program on implementation of ECBC, Star rated Appliances Energy efficient design (ECBC + NBC / low energy / passive strategies) + Renewable Energy (solar hot water integration and solar PV integration) GRIHA approach (combine ECBC with traditional wisdom and normative requirements of National Building Code) Promote through several schemes of the MNRE
GRIHA Compliant Building: Beyond ECBC 37% 45% ECBC Compliance: Insulation High Performance glass Controls Efficient electrical, mechanical and lighting systems Incremental cost: 15% Payback period < 5 years kwhr/yr GRIHA Compliance: ECBC + Passive principles (shading, orientation, controlled glass area) Higher indoor design conditions (higher by 1 deg C) Optimized lighting design No further incremental cost Payback period: < 4 years
Some think the solution lies in the west, or in developed countries..
Well, think again The real inconvenient truth
India Climate Mean monthly temp ( o C) Relative humidity (%) Hot and dry > 30 < 55 Warm and humid > 30 > 55 Moderate 25-30 < 75 Cold and cloudy Cold and sunny Composite < 25 > 55 < 25 < 55 When six months or more do not fall within any of the above categories
Approach to rating Western way Efficiency (primarily by usage of high performance envelope and energy efficient systems) Effectiveness not questioned (lighting level achieved, thermal comfort achieved- it is assumed that the design shall achieve the standards ) Economics Indian / GRIHA way Economics Effectiveness largely determined by economics too (visual / thermal comfort may be compromised to cut costs) Efficiency
Difference in Design Strategies The developed country approach to building design revolves around strategies that are devised to cater to situations specific to them. They do not have power, water and material shortages like us. They do not have an architectural and socio-cultural heritage like us. If we follow their model, our unique architectural identity that currently varies from climate zone to climate zone shall end, and all buildings across the land shall start looking identical boxes of steel and glass, like they are becoming today.

Energy efficient vs. green vs. sustainable buildings Energy efficient building Saves electricity and fuel (used for electricity generation) consumption Saves money in the long run Green buildings Saves natural resources such as trees, flora and fauna, water, energy, materials, waste, etc. Saves time if effort is put into planning Saves money and enhances the natural environment in the long run Sustainable buildings Do all of the above AND Generate their own energy, water, other resources such as food, etc. Recycle their own waste water, solid waste, organic waste, etc.
How can a GRIHA building be built? By ensuring the site conditions complement the thermal and visual comfort requirements of the building (very low-cost intervention) By adopting sound architectural practices and taking examples from India s traditional architecture (very low-cost intervention) By following India s national codes and standards (low-cost intervention) By following regional development plans (such as the master plan) and local building by-laws (low-cost intervention) By adopting locally available construction materials and giving impetus to local arts, crafts, architecture and artisans (low-cost intervention) By reducing the resource consumption of the building and its inhabitants so that the waste generating there-from is reduced (low-cost intervention) By adopting energy efficient technologies and equipments (High-cost intervention) By adopting renewable energy technology applications to reduce the demand on conventional energy (Very High-cost intervention) BUT HOW DOES ONE KNOW WHAT COMBINATION OF THE ABOVE FACTORS CAN HELP ATTAIN THE GREENEST POSSIBLE BUILDING?
Punch line What gets measured gets managed. So measures / metrics developed for Energy (kwh/m2/annum) Water usage in external, for construction and internal Kl/cd Rain water harvesting potential (l/m2) Renewable energy percentage (minimum 1% of combined HVAC and lighting connected load) No percentage reduction over hypothetical base cases based on international models EPI most stringent among global rating systems
Incentives 90% reimbursement of registration cost for highly rated building Cash prize for the design team (integrated design) Capital subsidy on all RE systems (PV as well as SWH) National Award Ceremony for recognition
And today 50 buildings registered for rating Over 2000 people trained in one-day and two-day programs Over 100 people trained in three day programs They are now conducting their own training programs and earning money from it too. At the same time taking the agenda forward. Several thousand school children taught the importance of green buildings, our culture, values and traditions We are now assisting other developing countries (Africa, SE Asia) in developing their own codes for green buildings, NOT asking them to adopt ours!!!
GRIHA acknowledged by UN
That gets us to Green Schools Really? That does get one thinking, doesn t it? What is a green school? Green Buildings? Green Campus? Green Uniform? Green Teachers? More Green Wash than is already doing the rounds?

BUT That s just the building! So
Environmental Education and Awareness Children s Charter during CoP 8 Project PACCIFY (Program for Awareness on Climate Change Issues for the Youth) Youth Conference on CoP 11 Youth Dialogue on Climate Change YUVA Youth Unite for Voluntary Action BEACON : Building Energy Awareness on Conservation Climate EduXchange- 2009 Indian Climate Champions (2008-2009) Innovative Methods Program on Action oriented Clean Technologies in Schools (IM-PACTS for Hewlett Packard) Sensitization, Education and Awareness on Recycling for a Cleaner Habitat (SEARCH) Awareness and capacity building Program Green Olympiad and Terra Quiz Public Participation program under YAP II
Green Schools let s s get real Our philosophy A green building cannot instil compassion in a student who is designed to perform in a cut-throat competitive environment, to eliminate all competition A green uniform cannot instil pride in a student who isn t aware how a regional dress in India (a kurta, dhoti, mund, salwar) is more climate responsive, ergo superior to a shirt / trouser / blazer / skirt A green environment club cannot sensitize a student towards the fact that India is a mega-diverse country; one among 17 others in the world, with the richest flora and fauna across the globe which the building industry is systematically destroying For that, we need a new curriculum
Green Schools Structure Economy External environment Building Internal Environment Society Faculty Focus - Student - Campus Ecology Curricula Culture
What it takes A green campus With a few green buildings In the richest natural surrounds (shade of trees, chabootras and open class rooms, play fields, social interaction, community ownership) Dr Vinod Gupta NIIT Campus Sanjay Prakash Mirambika, Pragyan Madhu Pandit The Srhi Ram School With a curriculum that sensitizes students about their country, their environment, and their future Madhu Bhatnagar, The Shri Ram School Krishnan Kutty, Woodstock School Suhasini Ayer, Auroville Sumita Das Gupta, Green Schools Program, CSE And instils compassion in them And with teachers who are as in-tune with their subjects, as they are with how their subjects interface with the environment Regardless of what others say It isn t t possible if we all don t t come together
