GENERAL SEMINER ON IGBC GREEN CAMPUS SOMNATH THANDER 001810201035 P-1

IGBC Sustainability science has grown Green Campus Rating System and become an important field of science over the last 15 years that seeks to understand the fundamental character of interactions between nature and society. Sustainability is environmentalism along with con- cern for social equity and economic development. Extensive researches are being carried out to enhance sustainability in the various fields. Campuses being the representative of larger human settlements is the best example for demonstrating sustain- able development (SD). Therefore, sustainability became an integral part of campus life. Higher Education Institutes (HEIs), around the world, are restructuring their ac- ademics and lifestyle on the campus following sustainability goals. As per the literature SD in HEIs of developed countries is at an advanced stage with the evolution and extensive use of various assessment systems. Lack of abundant literature on SD in Indian campuses compared to the global scenario of SD in HEIs, marks it as an essential study area. Indian campus- P-2

es have started to work in the direction of SD, but the pace is slow. There is a lack of holistic SD on Indian cam- puses. Indian campuses do not have a contextual campus assessment system for SD, and suitable indicators remain unestablished. Thus, there is a general lack of assessment of SD on Indian campuses. IGBC Green Campus rating system is one of their recent steps to embrace the green concepts in the various campuses such as - • administrative campus, • convention centres, • educational campuses, • healthcare campuses, • hospitality campuses • it parks, • industrial parks, • leisure and recreational campus- es military campuses, • religious campuses, etc. Green campuses address the issue of water efficiency, energy efficiency, reduction in the use of fossil fuel for- transportation and efficient P-3

handling of consumer, thus conserv- ing natural resources. They enhance the occupant’s health, wellbeing, safety and security. II. Benefits of Green Campuses: Green Campuses can have tremen- dous benefits, both tangible and in- tangible. The most tangible benefits are the reduction in water and energy consumption right from day one of occupancy. The energy savings could range from 20 - 30 % and water sav- ings around 30 - 50%. Intangible bene- fits of green campus include health & well-being of the occupants, enhanc- ing air quality & promoting biodiversi- ty, safety benefits and conservation of scarce national resources. III. National Priorities Addressed in the Rating System : The IGBC Green Campus rating system addresses the most import- ant National priorities which include water conservation, handling waste, energy efficiency, reduced use of P-4

fossil fuels and health & well-being of occupants. The rating system requires the application of National standards and codes like the Bureau of Indian Standards (BIS), Central Ground Water Board guidelines, Central Pollution Control Board guidelines, Energy Conservation Building Code (ECBC), MNRE Guidelines, MoEFCC guidelines, National Building Code (NBC), and Renewable Energy Certificates (RECs). The overarching objective is to better the National standards so as to create new benchmarks. Water Conservation: Most of the Asian countries are water stressed and in countries like India, the water table has reduced drastical- ly over the last decade. IGBC Green Campus rating system encourages use of water in a self-sustainable manner through reducing, recycling and reusing strategies. By adopting this rating programme, green campus can save potable water to an extent of 30 – 50%. P-5

Handling of Construction Waste: Handling of waste in campuses 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 intends to address this by encourag- ing buildings to segregate the waste generated in the campus. Energy Efficiency: The Buildings sector is a large con- sumer of electrical energy. Through IGBC Green Campus rating system, campuses can reduce energy con- sumption through energy efficient –exterior lighting, air conditioning sys- tems, etc. Also, alternative resources or energy are encouraged. The energy savings that can be realized by adopt- ing this rating programme can be to the tune of 20 – 30% P-6

Reduced Use of Fossil Fuels: P-7 Fossil fuel is a slowly depleting re- source, world over. The use of fossil fuel for transportation has been a major source of pollution. The rating system encourages the use of alter- nate fuels for transportation. Health and Well-being of Occupants: Health and well-being of occupants is the most important aspect of IGBC Green Campus rating system. The rating system ensures facilities to en- hance health and occupant well-being which are critical in a campus. IV. IGBC Green Campus rating sys- tem: 1. Features: IGBC Green Campus rating system is a voluntary and consensus based programme. The rating sys- tem has been developed based on

materials and technologies that are presently available. The objective of IGBC Green Campus rating system is to facilitate the creation of water efficiency, handling of waste, energy efficiency, and environmentally friendly campuses. The rating system evaluates certain mandatory requirements & credit points using a prescriptive approach and others on a performance-based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly. The programme is fundamentally designed to address National priorities and quality of life for occupants. P-8

Some of the unique aspects ad- P-9 dressed in this rating system are as follows: • Optimisation of water use for con- struction • Improving lung space in the campus by emphasizing on green cover • Encourage more green buildings in the campus • Effective management of waste generated in campus • Promotion of bicycles as a mode of transportation • Encourage facilities for improving health & well-being of occupants 2. Scope: IGBC Green Campus rating system is designed for both New and Existing Campuses. The types of Campuses include Administrative campuses, Convention centers, Educational cam- puses, Healthcare campuses, Hospi- tality campuses, IT parks, Industrial

parks, Leisure & Recreational cam- puses, Military campuses, Religious campuses, etc., Buildings within the campus such as new buildings, exist- ing buildings, factory buildings, etc., will be covered under their respective IGBC rating programmes. IGBC Green Campus rating system is broadly classified into two types: • New Campuses • Existing Campuses 3. Validity: The rating awarded for the campus- es would be valid for a period of 5 years. Thereafter, the campuses have to apply for re-certification with the prevailing version. The campuses can also apply for re-certification within 5 years of award of the rating for a superior rating, if new green features are implemented or existing green features are enhanced in the campus. P - 10

Overview and Process: IGBC Green Campus rating system addresses green features under the following categories: • Site Planning and Management • Sustainable Transportation • Water Conservation • Energy Efficiency • Material and Resource Manage- ment • Health & Well-being • Green Education • Innovation in Design P - 11

Different levels of green campus certification are awarded based on the total credits earned. However, every green campus should meet certain mandatory requirements. The various levels of rating awarded are: Certification Level Recognition Certified Best Practices Silver Outstanding Performance Gold National Excellence Platinum Global Leadership P - 12
