GREEN BUILDING RATING SYSTEM

7. INTRODUCTION OF GRIHA
WHAT IS GRIHA?
Name: GRIHA is an acronym for Green Rating for Integrated Habitat
Assessment.
Country: INDIA
Established : 2007
GRIHA is a Sanskrit word meaning –‘Abode’.
A innovative tool for sustainable development by the united nations
A tool for implementing renewable energy in the building sector by
‘The Climate Reality project’-an organization founded by Mr. Al Gore;
and UNEP-SBCI has developed the “Common Carbon Metric” (kWhr/sq
m/annum), for international building energy data collection -based on
inputs from GRIHA (among others)

8. There are three primary Rating systems in India:
GRIHA (Green Rating for Integrated Habitat Assessment)
Green Rating for Integrated Habitat Assessment (GRIHA) is India’s own rating
system jointly developed by TERI and the Ministry of New and Renewable
Energy, Government of India.
IGBC (Indian Green Building Council)
LEEDisdevelopedbytheU.S.GreenBuildingCouncil(USGBC),the
organizationpromotingsustainabilitythroughGreenBuildings.
BEE(BureauofEnergyEfficiency)
It has star based rating system: more stars mean more energy
efficiency.BEE has developed the Energy Performance Index (EPI). The unit
of Kilo watt hours per square meter per year is considered for rating the
building and especially targets air conditioned and non-air conditioned office
buildings.

9. EVOLUTION OF GRIHA

11. OBJECTIVE 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 standardfor what constitutes a ‘green building’
Based on accepted energy and environmental principles,
seeks to strike a balancebetween the established practices
and emerging concepts
Reduced energy consumption without sacrificing the comfort
level
Reduced destruction of natural areas, habitats, and
biodiversity,and reduced soil loss from erosion etc.

12. WHY CHOOSE GRIHA?

19. GRIHA RATING SYSTEM
VARIANTS OF GRIHA
SVAGRIHA FOR BUILDING AREA-100-2499 sqm
GRIHA FOR BUILDING AREA-2500-1,50,000 sqm
GRIHA LD FOR BUILDING AREA-> 50 hectare site area
GRIHA VERISON 2015
The latest version of GRIHA, GRIHA version 2015 (GRIHA V2015), was introduced
in January 2015.
The GRIHA V 2015 rating system consists of 31 criteria
categorized under various sections such as Site Planning, Construction
Management, Occupant Comfort and Wellbeing, Sustainable Building
Materials, Performance Monitoring and Validation, and Innovation
Eligibility
All buildings, which are in the design stage and have built up area more than
2,500 m2,are eligible for certification under GRIHA.

20. GRIHA RATING CRITERIA
Criteria and their weightage
GRIHA is a performance-oriented system where points are earned for meeting the
design and performance intent of the criteria.
Each criterion has certain points assigned to it. It means that a project demonstrating
compliance with a criterion would achieve the associated points.
GRIHA is a 100-point system consisting of some core points
Different levels of certification (one star to five stars) are awarded based on the
number of points earned. The minimum points required for certification are 25.

21. GRIHA RATING CRITERIA
EVALUATED IN DIFFERENT STAGES
Pre-construction stage (intra-and inter-site issues)
Building planning and construction stages (issues of resource conservation and
reduction in resource demand, resource utilization efficiency, resource recovery and
reuse, and provisions for occupant health and well being). The prime 4 resources
that are considered in this section are land, water, energy, air, and green cover.
Building operation and maintenance stage (issues of operation and maintenance of
building systems and processes, monitoring and recording of consumption, and
occupant health and well being, and also issues that affect the global and local
environment).

22. GRIHA RATING CRITERIA

23. GRIHA RATING CRITERIA

24. GRIHA OVERVIEW

The terrace garden utilizes preserved top
soil extracted during the initial
excavation
ENERGY POSITIVE APPROACH

29. ENERGY POSITIVE APPROACH
More than 50% area
outside the building
is soft with plantation
and grassing.
Circulation roads and
pathways soft with
grass paver blocks to
enable ground water
recharge
Polymer plastics grids turn the
visual asphalt fire tender road into a
soft paved space
Preservation of existing
foliage increasing the front
set back.

30. SITE AND WASTE WATER MANAGEMENT
To reduce landscape water requirements
Drip irrigation
Use of native species of shrubs and trees
having low water demand in landscapping
Low lawn areas so as to reduce water
demand
Reuse of treated water for irrigation
Reduce water use in building
Dual flushing cistern
Low discharge fixtures
Waste water treatment
Reuse of treated water for irrigation and
cooling towers of HVAC
Rain water harvesting –efficient water use
during construction
Drip
irrigation
Appropriate shading from summer sun ,while allowing in winter sun

31. MATERIALS AND CONSTRUCTION TECHNIQUES
Ready Mix Concrete with PPC having more than 30% fly ash content -
Fly ash brick.
Stone available in nearby area for Terrazzo flooring
AAC(Aerated Autoclaved Cement ) blocks.
Renewable bamboo jute composite material for door frames &
shutters.
UPVC windows with hermetically sealed double using low heat
transmittance index glass.
Use of high reflectance terrace tiles for low heat ingress.
Avoided aluminum as it has high embedded energy
Sandstone jaalis, stone and ferro-cement jaalis
Grass paver blocks for ground water recharge

32. ENERGY CONSUMPTION ON SITE -ZERO ENERGY

33. Extra efficient Solar photo voltaic (SPV) proposed (Terrace and
projections) =800 kW
Energy produced in building/year = 14,91,000 Kwh
Energy consumption for building/year = 14,21,000 kWH

34. Geo thermal heat exchange system
180 vertical boresto the depth of 80 meter all along
the building premises.
Minimum 3 meter distance is maintained between any
two bores.
Each borehas HDPE pipe U-loop (32mm outer diameter)
and grouted with BentoniteSlurry.
Each U-Loop is connected to the condenser
waterpipe systemin the central air conditioning plant
room.
One U-Loop has 0.9 TR heat rejection capacity.
Combined together, 160 TR of heat rejection is
obtained without using a cooling tower.
Water pumping and treatment costs gets eliminated.
Saves cooling tower fan energy.

35. HVAC system -Chilled beam system
160 TR of air conditioning load of the building is met
through Chilled beam system.
Chilled beam are usedfromsecond to sixth floor. This
reducesenergy use by 40 % compared to a conventional
system.
HVACload of the buildings is 40 m
2
/TR, about 50% more
efficient than ECBC requirements (20 m
2
/TR)
Chilled beams save AHU/FCU fan power consumption
by approximate 50 kW.
Freshsupply air is pre cooled from toilet exhaust air
through sensible & latent heat energy recovery wheel.

36. NET ZERO DESIGN
IPB reduces energy requirements by 70% overall by conventional
N-S orientation –Limiting WWR (Window to wall ratios )
Insulation on wall and roof
Extensive greenery to reduce heat load
Maximizing day lighting to reduce lighting loads
Extremlylow lighting power density -5 w/sqm
Planning to minimize AC loads (keeping open atrium for cross
ventilation, non conditioned lobbies)
Efficient HVAC with screw chillers , VFD’S , Chilled beams
Ground based heat exchanger for condenser water
