1. EVALUATING SYSTEM FOR WATER
MANAGEMENT

2. GREEN BUILDING RATING SYSTEM
A green building rating system is an evaluation tool that measures environmental
performance of a building through its life cycle
Comprises of a set of criteria covering various parameters related to design,
construction and operation of a green building
Each criterion has pre-assigned points and sets performance benchmarks and
goals that are largely quantifiable
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.
Globally, green building rating systems are largely voluntary in nature and have
been instrumental in raising awareness and popularizing green building
designs.

3. Government body and policy guidelines responsible for assessing sustainability in
buildings sector in India:
•NBC, 2005
•ECBC, 2007
•Local byelaws
Prevalent building rating systems in India
GRIHA: Green rating for integrated habitat assessment(National Rating System)
LEED: Leadership in energy and environmental design
More than 30 rating systems followed world wide
Some of the green building rating systems
United Kingdom –BREEAM
Australia –Green Star
Japan –CASBEE
United States –LEED
Canada –LEED Canada
India –LEED India

4. •Leadership in Energy and Environmental Design (LEED®) was developed and
piloted in the US in 1998 as a consensus-based building rating system based on
the use of existing building technology.
•The rating system addresses specific environmental building related impacts
using a whole building environmental performance approach.
•The Indian Green Building Council has adapted LEED system and has
launched LEED India version for rating of new construction.
•Indian Green Building Council (IGBC) has launched several other products for
rating of different typologies of buildings including homes, factories, among
others.

There are credits for each criterion under the
broad categories. These criteria credits are
earned by addressing the specific environmental
impact in design and construction. A total of up
to 100 credits can be earned. The credit
requirement for different levels of rating is as
follows:

15. GRIHA: Green Rating for Integrated Habitat Assessment
•National Rating System of India.
•The rating can be applied to new and existing buildings of various uses.
•The rating system is based on national and international energy and
environmental principles.
•GRIHA has derived inputs from the codes and guidelines developed by the
Bureau of Energy Efficiency, the Ministry of Non-Conventional Energy Sources,
MoEF (Ministry of Environment and Forests), Government of India, and the
Bureau of Indian Standards.
•The rating system aims to achieve efficient resource utilization, enhanced
resource efficiency, and better quality of life in the buildings.

16. Zero water discharge building
System35% reduction in potable water use
Low flow water fixtures
Waterless urinals
Use of storm water & recycled water for irrigation.
Entire waste water in the building is treated biologically through
a process called the 'Root Zone Treatment
Water system
❑ Collect rainwater for external use i.e. garden/washing car.
❑ Use water conserving appliances including toilets, shower, taps, washing machine and dish
washer e.g.. Low flow faucets, water saving dual flush tanks
❑ Reduce irrigation and surface water run-off .

19. Intent:
The intent of this criterion is to ensure reduction in the building water consumption
through the use of low-flow fixtures.
Maximum Points: 4
Appraisals:
• 14.1.1: Reduce water demand through selection of low-flow fixtures by 30% below the
GRIHA base case – Mandatory
• 14.1.2: Reduce water demand through selection of low-flow fixtures by 50% below the
GRIHA base case – 2 points
• 14.1.3: Reduce water demand through selection of low-flow fixtures by 70% below the
GRIHA base case – 4 points

20. Intent:
The intent of this criterion is to promote the planting of native/naturalized flora and use
of water efficient irrigation system to reduce the demand for landscape water.
Maximum Points: 4
Appraisals:
• 15.1.1: Reduce landscape water demand by at least 30% from the GRIHA base case – 1
point
• 15.1.2: Reduce landscape water demand by at least 40% from the GRIHA base case – 2
point
• 15.1.3: Reduce landscape water demand by at least 50% from the GRIHA base case – 4
point

21. • Ensuring quality of water available for use during building operation is important from
two perspectives
– overall hygiene for building occupants as well as longevity of plumbing systems.
• It is also important to ensure that the water being discharged from the site meets the
relevant disposal norms.
• The intent of this criterion is to ensure that the water being used in the project meets
the relevant national standards.
16.1.1: Water used for various purposes like drinking, irrigation etc. shall conform to
the BIS standards – Mandatory
•16.1.2: The STP installed on site meets the CPCB norms – 2 points

22. Intent:
The intent of this criterion is to promote recycle and reuse of waste water as well as
reuse of captured rainwater on site to meet the water demand, thereby reducing the
water required from the local municipal supply/groundwater aquifers.
Maximum Points: 5
Appraisals:
•17.1.1: Demonstrate that the project meets the on-site water reuse requirements
(through on-site recycle and reuse of waste water and use of on-site harvested
rainwater) in its annual water requirements for domestic use, buildings, landscape and
utilities as mentioned below:

23. Intent:
The intent of this criterion is to promote the recharge of groundwater aquifers.
Maximum Points: 2
Appraisals:
•18.1.1: Recharge of surplus rainwater into aquifer (through appropriate filtration
measures) – 2 points

24. Grape County Resort
Location : Khambala, Nashik
Site Area : 21,433 sq.m.
Built up area : 1475 sq.m.
Typology : Resort
SVA GRIHA rating : 5 star
• The project meets 100% of the total building water demand for over 2 days, through
rainwater harvesting.
• STP (Sewage Treatment Plant) based on reed bed system treats 100% of sewage
generated from the project. The treated water from STP is reused for irrigation purpose.
• Reduction in landscape water demand by 88.49%, below the SVAGRIHA base case, has
been achieved due to installation of sprinklers and drip irrigation system as well as
plantation of only native and naturalized trees.
• Reduction in building water demand by 57.95%, below the SVAGRIHA base case, has
been achieved due to use of low-flow plumbing fixtures and aerators.

25. • No dependency on any external water supply source like local planning authority, even in
summers due to creation of water reservoir as an outcome of efficient rainwater harvesting
scheme/plan.
• Provision of vermi-composting pits on site to treat 30 cu.m. organic waste generated from
site.
