3. Why Buildings are being rated?

4. Buildings have extensive direct
and indirect impacts on the
environment.
During their construction,
occupancy, renovation, repurposing,
and demolition, buildings use
energy, water, and raw materials,
generate waste, and emit potentially
harmful atmospheric emissions.
These facts have prompted the
creation of green building standards,
certifications, and rating systems
aimed at mitigating the impact of
buildings on the natural environment
through sustainable design.

5. How did it
start?
• The push toward sustainable design increased with the launch in 1990 of Building Research
Establishment's Environmental Assessment Method (BREEAM), the first green building
rating system in the world.
• In 2000, the U.S. Green Building Council (USGBC) followed suit and developed and
released criteria also aimed at improving the environmental performance of buildings through
its Leadership in Energy and Environmental Design (LEED) rating system for new
construction.
• Since that first release, LEED has continued to grow in prominence and to include rating
systems for existing buildings and entire neighborhoods.
• Others also responded to the growing interest and demand for sustainable design including
the Green Building Initiative (GBI), which was created to assist the National Association of
Homebuilders (NAHB) in promoting its Green Building Guidelines for Residential Structures.
• Although originally developed for Canada, GBI helped to make Green Globes available for
use in the U.S. in 2005.
• Additional rating systems have been developed that were influenced by these early
programs but are tailored to their own national priorities and requirements or seek to go
beyond the limits of current policy and building practices to address broader issues of
sustainability or evolving concepts such as net zero energy, and living and restorative
building concepts that improve the natural environment, or those that model nature's
processes.

8. GREEN BUILDING AGENCIES AND INSTITUTIONS

11. WHAT IS A GREEN BUILDING ?
• Green Buildings are structures that ensure efficient use of natural resources like building
materials, water, energy and other resources with minimal generation of non-degradable
waste.
THE CONCEPT OF A GREEN BUILDING HAS THE FOLLOWING :-
 Sustainable site planning.
 Building Design optimization.
 Energy performance optimization.
 Renewal energy utilization.
 Water and Waste management.
 Solid waste management.
 Sustainable building material and construction technology.
 Health, well being and environmental quality.

12. • Technologies like efficient cooling systems
have sensors that can sense the heat
generated from human body and
automatically adjust the room
temperature, saving energy.
• It applies to lighting systems too. Green
buildings have a smarter lighting system
that automatically switches off when no
one is present inside the rooms.
• Simple technologies like air based flushing
system in toilets that avoids water use by
100%, use of energy efficient LED’s and
CFL’s, new generation appliances that
consume less energy, and many other
options help in making the buildings green.

13. GREEN BUILDING RATING SYSTEMS
• A green building rating system is an evaluation tool that
measures environmental performance of a building
through its life cycle.
• It comprises of a set of criteria covering various
parameters related to design, construction and operation
of a green building.
• A project is awarded points once it fulfills the rating
criteria. The points are added up and the final rating of a
project is decided.
There are three primary Rating systems in India:-
• GRIHA
• IGBC
• BEE

GREEN
BUILDING
RATING
PROGRAMS
• BREEAM
• CASBEE
• IGBC
• GB TOOL

17. BREEAM: BUILDING RESEARCH ESTABLISHMENT’S
ENVIRONMENTAL ASSESSMENT METHOD
• Building Research Establishment’s Environmental
Assessment Method was developed in UK in 1990.
• Covers a range of building types : offices, homes,
industrial units, retail units, and schools.
• Points are awarded for each criterion and the points
are added for a total score.
• The overall building performance is awarded a
‘Pass’, ‘Good’, ‘Very Good’ or ‘Excellent’ rating
based on the score.
BREEAM has separate criteria/checklist for evaluation
of:-
• Design and Procurement.
• Management and Operation of buildings.

18. CASBEE:
COMPREHENSIVE ASSESSMENT SYSTEM FOR
BUILDING ENVIRONMENTAL EFFICIENCY
• Comprehensive Assessment System for Building
Environmental Efficiency (CASBEE) was developed
in Japan, in 2001.
• The family of assessment tools is based on the
building’s life cycle: pre-design, new construction,
existing buildings, and renovation.
Under CASBEE there are two spaces, internal and
external, divided by the hypothetical boundary, which
is defined by the site boundary and other elements,
in which the:-
• ‘Negative aspects of environmental impact which
go beyond the hypothetical enclosed space to the
outside (the public property)’.
• ‘Improving living amenity for the building users’ are
considered side by side.

19. LEED: LEADERSHIP IN ENERGY
AND ENVIRONMENTAL DESIGN
• LEED is the rating system developed for
certifying Green Buildings. LEED is
developed by the U.S. Green Building
Council (USGBC), the organization
promoting sustainability through Green
Buildings.
• LEED is changing the way we think about
how buildings and communities are
planned, constructed, maintained and
operated.
• Certification of green building based on the
number of points achieved a project then
receives one of four LEED rating levels:
Certified, Silver, Gold and Platinum.
• LEED-certified buildings are resource
efficient. They use less water and energy
and reduce greenhouse gas emissions. As an
added bonus, they save money.

20. GB TOOL:
• GB Tool Green Building Challenge Assessment Framework was developed by the International Framework Committee for
the Green Building Challenge, an international project that has involved more than 25 countries since 1998.
• GB Tool is designed to be adapted by sponsors to reflect regional conditions and context.
It includes criteria in categories :
• Site Selection.
• Project Planning and Development.
• Environmental Loadings.
• Energy and Resource Consumption.
• Indoor Environmental Quality.
• Functionality.
• Long-Term Performance.
• Social and Economic Aspects.
• Criteria are assessed using scales that are based on local benchmarks of ‘typical’ practice.

21. GRIHA
GREEN
RATING FOR
INTEGRATED
HABITAT
ASSESSMENT

22. Green Rating for Integrated Habitat Assessment (GRIHA)
• Green Rating for Integrated Habitat Assessment (GRIHA) is the national rating
system of India for any completed construction, endorsed by the Ministry of New
& Renewable Energy (MNRE), Government of India and TERI. It is an
assessment tool to measure and rate a building’s environmental performance.
• The basic features of GRIHA:
The scheme was created to assist in ‘designing and evaluating’ new buildings
(structures that are still at the starting phases). A building is evaluated based on its
expected results over its full life. The stages of the life cycle that have been
identified for evaluation are:

23. GRIHA: GREEN RATING FOR INTEGRATED
HABITAT ASSESSMENT
• GRIHA will evaluate environmental performance of
buildings holistically over its entire lifecycle, thereby
providing a definitive standards for what constitute a
green building.
• GRIHA has been conceived by TERI and developed
jointly with the Ministry of New and Renewable
Energy, Government of India.
• It is a green building 'design evaluation system', and
is suitable for all kinds of buildings in different
climatic zones of the country.
• ADARSH, (Association for Development and Research
of Sustainable Habitats) founded jointly by TERI (The
Energy and Resources Institute, New Delhi) promotes
GRIHA as a design & evaluation tool for Green
Buildings and Habitats.

24. OBJECTIVES OF GRIHA :
Minimize a building’s resource consumption, waste generation, and overall
ecological impact.
Evaluates the environmental performance of a building holistically over its
entire life cycle, thereby providing a definitive standard for what constitutes a
‘green building’.
Based on accepted energy and environmental principles, seeks to strike a
balance between the established practices and emerging concepts.
Reduced energy consumption without sacrificing the comfort levels.
Reduced destruction of natural areas, habitats, and biodiversity, and reduced
soil loss from erosion etc.

25. EVOLUTION OF GRIHA

26. GRIHA RATING CRITERIA
 Except for industrial complexes, all buildings – offices, retail malls, institutions, hotels, hospitals, health-care
facilities, residences, and multi-family high-rise buildings – in the pre-design/design stage are eligible for
certification under GRIHA.
 The percentage of total outdoor lighting fixtures with solar lighting system, as per GRIHA tenets which is a
minimum of 25% of total number or 15% of total connected load, whichever is higher, can fetch 1 point.
 Demonstrated use of minimization and consolidation of transportation or service corridors and shading of
pedestrian roads, as per GRIHA can garner 1 point.
 The Use of aggregate utility corridors, as per GRIHA is another point to the kitty.
 Furthermore, firming up of utility corridors along the formerly disturbed areas or along new roads in order to
reduce needless cutting and trenching and ensure easy maintenance is also a GRIHA point.

• Year of completion : 2013
India’s first net zero building
This means that this is a building with zero net energy consumption where the total amount of energy
used in the premises on an annual basis is more or less equal to the amount of renewable energy
created on the site.

69.  This project has been developed at an expense of about 209 crore rupees. The Indira Paryavaran Bhavan
building has already received the following awards:
• February 2013: The Project received an award from Adarsh/GRIHA of MNRE for exemplary demonstration of
Integration of Renewable Energy Technologies

The Bhawan is India’s first on site Net Zero Building built by the adoption of Solar
Passive design and energy efficient building material. This has been designed as
the highest-green rated building i.e., GRIHA 5-Star and LEED India Platinum. The
requirements of GRIHA 5-Star and LEEDS Platinum ratings have been achieved by
adopting various measures some of which are as follows

70. Effective Ventilation has been achieved by orientating the building in an East-West direction, separating different blocks with
connecting corridors and having a large central court yard.
• The design is such that 75% of natural daylight is utilised to reduce energy consumption.
• The entire building has an access friendly design for differently-abled persons.
• With an Installed capacity of 930 KW peak power, the building has the largest roof top Solar system among Multi storied
buildings in India.
• Total energy savings of about 40% has been achieved by adoption of energy Efficient Chilled Beam system of Air
Conditioning. This is an innovative air conditioning system, where air conditioning is done by convection currents rather than
air flow through diffusers and chilled water is circulated right up to the diffuser points unlike the conventional systems.
• Green materials have been used like Fly ash bricks, regional building materials, materials with high recycled content, high
reflectance terrace tiles and rock wool Insulation of outer walls.
• Rapidly renewable Bamboo Jute Composite material has been used for door frames & shutters.
• UPVC windows with hermetically sealed double glass, Calcium Silicate ceiling tiles having high recycled content and grass
paver blocks in pavements and roads.
