Introduction (Contd. . . ) Ø Green Building (also known as green construction or sustainable building) expands and compliments the building design concerns of economy, utility, durability and comfort. Ø A Green Building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier space for occupants as compared to conventional building. Ø Green buildings are designed to reduce the overall impact on human health and natural environment. • Using energy, water and other resources efficiently. • By reducing waste, pollution and environmental degradation. 3 VANKIRI MADHU (203418025) / M.

Green Building Rating System Ø A green building rating system is an evaluation tool that measures environmental performance of a building through its life cycle Ø Comprises of a set of criteria covering various parameters related to design, construction and operation of a green building Ø Each criterion has pre-assigned points and sets performance benchmarks and goals that are largely quantifiable Ø A project is awarded points once it fulfillsthe rating criteria. The points are added up and the final rating of a project is decided. Ø Globally, green building rating systems are largely voluntary in nature and have been instrumental in raising awareness and popularizing green building design. 6 VANKIRI MADHU (203418025) / M. Tech. (EE) / Civil Engg.
Green Building Rating System Ø some of the rating systems are • BREEAM: Building Research Establishment’s Environmental Assessment Method was developed in UK in 1990. • GBTool: GBTool was developed by the International Frame work Committee for the Green Building Challenge, an international project that has involved more than 25 countries since 1998. • LEED: Leadership in Energy and Environmental Design was developed in the US in 1998. • CASBEE: Comprehensive Assessment System for Building Environmental Efficiency was developed in Japan, in 2001. • IGBC: Indian Green Building Council was formed in the year 2001. 7 VANKIRI MADHU (203418025) / M.

U. S. Green Building Council • Brief history of USGBC: • The U. S. Green Building Council (USGBC), co-founded by Mike Italiano, David Gottfried and Rick Fedrizzi in 1993, is a non-profit trade organization that promotes sustainability in how buildings are designed, built, and operated. USGBC is best known for the development of the LEED green building rating systems. 19 VANKIRI MADHU (203418025) / M. Tech. (EE) / Civil Engg.
• What is LEED? • LEED (Leadership in Energy and Environmental Design) is a voluntary, market-driven program that provides third-party verification of green buildings. • From individual buildings and homes, to entire neighbourhoods and communities, LEED is transforming the way built environments are designed, constructed, and operated. Comprehensive and flexible, LEED addresses the entire lifecycle of a building. • It provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. 20 VANKIRI MADHU (203418025) / M.

LEED RATING IN INDIA • IGBC has licensed the LEED Green Building Standard from the U. S. Green Building Council and currently is responsible for certifying LEED-New Construction and LEED-Core and Shell buildings in India. There are many energy efficient buildings in India, situated in a variety of climatic zones. • Indian Green Building Council, is continuously striving towards wider adoption of eco-friendly / green building concepts in the Indian Industry. 28 VANKIRI MADHU (203418025) / M.

ADVANTAGES AND DISADVANTAGES OF LEED RATING SYSTEM IN INDIA • LEED India certified projects blend enhanced environmental, economic, and occupant-oriented performance. • They cost less to operate and maintain; are energy- and waterefficient; have higher lease-up rates than conventional buildings in their markets and are healthier and safer for occupants. • Often when a LEED rating is pursued in India, it increase the cost of initial design and construction. • One reason for the higher cost is that sustainable construction principles may not be well understood by the design professionals undertaking the project. • Some of the finer points of LEED certification in India could possibly lead to misunderstandings between the design team, construction team, and client, which could result in delays. Also, there may be a lack of abundant availability of manufactured building components which meet LEED standards. 31 VANKIRI MADHU (203418025) / M. Tech. (EE) / Civil Engg.
