13STRUCTURE DESIGN EFFICIENCY:

Design of the building have an important role in cost and performance of the building throughout the life cycle.

It aims to minimize the environment impact.

ENERGY EFFICIENCY:

The layout of the construction can be strategized so that natural light is a source for additional warmth.

Shading the roof with trees offers an eco-friendly alternative to air conditioning

14WATER EFFICIENCY:To minimize water consumptionRain water which has been collected, used, purified and reused.

MATERIAL EFFICIENCY:Materials which are used should be recycled Should generate surplus amount of energy.Ex : Solar power panels for lightening and also a useful energy source.

WASTE REDUCTION:In green buildings all materials and energy sources are efficiently used so that it ensures reduced waste generation.

BREEAM(Building Research Establishment Environmental Assessment Methodology), first published by theBuilding Research Establishment(BRE) in 1990,[1]is the worlds longest established method of assessing, rating, and certifying thesustainabilityof buildings. More than 250,000 buildings have been BREEAM certified and over a million are registered for certification many in the UK and others in more than 50 countries around the world.16

Austin Energy Green Building17In 1990, the City of Austin established the first green building programme in the U.S

The Austin Energy Green Building (AEGB) program encourages to design and construct more sustainable homes and buildings by creating a rating system.

Energy Star18

Its an international standard forenergy efficientconsumerproducts originated in the United States.

It was created in 1992 by theEnvironmental Protection Agency and theDepartment of Energy.

Devices using energy star mark, such as computers, kitchen appliances uses 20-30% less energy.

19TheU.S. Green Building Council(USGBC), co-founded by Rick Fedrizzi, Mike Italiano, and David Gottfried in 1993.

Its a non-profit organization that promotes sustainability in buildings design, construction, and operation.

USGBC is best known for its development of theLeadership in Energy and Environmental Design (LEED) green building rating system.

Indian Green Building Council

20TheIndian Green Building Council (IGBC), was formed in the year 2001 by Confederation Indian Industry (CII).

The vision of the council is to bring a green building movement in India and facilitate India to become one of the global leaders in green buildings by2021.

Today more than 1053 green buildings are being constructed all over India, of which 810 green buildings are certified and fully functional.

LEED(Leadership in Energy and Environmental Design)GRIHA(Green Rating for Integrated Habitat Assessment)

Leadership in Energy and Environmental Design

22Leadership in Energy and Environmental Design (LEED) is one of the most popular green building certification programs used worldwide.

Developed by the non-profit U.S. Green Building Council (USGBC) it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighbourhoods.

23

The Gold and Platinum rating of David L. Lawrence Convention Center inPittsburgh is the first convention center in the world to have such certifications.

Abad Nucleus Mall, atMaradu,Kochi, isIndia's first LEED certified gold-rated green mall.

24

TheTower at PNC Plazais askyscraperinPittsburgh,Pennsylvania The tower is one of the greenesthigh-riserever built, and even exceeds the current criteria for aLEED Platinum certified building

Taipei 101, the tallest and largest green building of LEED Platinum certification in the world since 2011

The Tower features numerous sustainable attributes such as an operabledouble-skin facade, an onsitegrey waterreuse system, locally sourced building materials, fixtures and furniture made from recycled materials, and numerous other green strategies to substantially reduce the environmental impact of the building. Some of these features enable the Tower's heating and cooling systems to operate in a "net-zero-energy state" up to 30% of the year.[6][7]This is accomplished by its innovativesolar chimney, which creates a stack effect through the core of the building to ventilate excess heat without the need formechanical ventilation. The Tower's sloped roof acts as asolar collectorand is positioned facing south.24

Green Rating for Integrated Habitat Assessment

GRIHA attempts to minimize a buildings resource consumption, waste generation, and overall ecological impact to within certain nationally acceptable limits / benchmarks.

It evaluates the environmental performance of a building holistically over its entire life cycle and provides a definitive standard for what constitutes a green building

CASE STUDY 1

28

Objective of the study

29To study the LEED and GRIHA rating system and compare both with regards to their assessment methods; scopes, performance criteria and energy rating scales.

MATERIAL AND METHODS

30First they have compared between LEED and GRIHA rating system.

Comparison was done based the categories by which they provide rating.

GRIHA rating system uses an offline questionnaire- based approach.

LEED is documentation intensive, more complex , time consuming process.

33

CONCLUSIONBoth rating system are good enough to be used.

Each system has certain strong and weak points.

These two system are based on different parameters hence there is a possibility that both systems rate the same system differently.

CASE STUDY 2

35

Objective of the study

36 To provide an overview of the LEED-India and GRIHA programs and examine the spatial dynamics of projects developed under LEED-India and GRIHA requirements.

MATERIAL AND METHODS

37Data were collected from the Indian Green Building Council (IGBC) on LEED-India projects and from the Association for Development and Research of Sustainable Habitats (ADaRSH) for GRIHA projects.

Data have been collected from all green projects that are certified by one of the rating systems from the respective organizations.

Each project was reviewed to determine its geographic location (i.e. state or union territory) and type of project (e.g. residential, commercial, industrial, etc.).
