This document discusses the Indian Green Building Council's (IGBC) green building rating system for residential buildings, called IGBC Green Homes. It provides an overview of IGBC Green Homes and its voluntary rating system, which evaluates new and renovated residential buildings across several criteria, including energy efficiency, water conservation, and indoor environmental quality. The rating system provides certification levels from Certified to Platinum based on the total credits earned. The document also includes a case study of a Platinum-rated green school project in Vadodara, Gujarat that utilized various green design, material, and energy saving features.

2. What is IGBC ?
Indian Green Building Council (IGBC) Green Homes is the first rating program developed
in India, exclusively for the residential sector. It is based on accepted energy and
environmental principles and strikes a balance between known established practices and
emerging concepts. The system is designed to be comprehensive in scope, yet simple in
operation
IGBC Green Homes Rating System is a voluntary and consensus based program. The rating
system has been developed based on materials and technologies that are presently available.
The objective of IGBC Green Homes is to facilitate the effective use of site resources,
water conservation, energy efficiency, handling of house-hold waste, optimum material
utilization and design for healthy, comfortable & environmentally friendly home

3. Benefits
A Green Home can have tremendous benefits, both
tangible and intangible. The immediate and most
tangible benefit is in the reduction in water and
operating energy costs right from day one, during
the entire life cycle of the building.
Tangible Benefits:
Energy savings : 20 - 30%
Water savings : 30 - 50%
Intangible Benefits:
Enhanced air quality
Excellent day lighting
Health & wellbeing of the occupants
Conservation of scarce national resources
Enhance marketability for the project
IGBC Green Homes Rating System
It is a measurement system designed for rating new
and major renovation of residential buildings which
are broadly classified into two construction types:
- Individual residential unit
- Multi-dwelling residential units
o Gated communities.
o High-rise residential apartments.
o Hostels, Service apartments,
Resorts, Motels and Guest houses.
IGBC Green Homes is designed primarily for new
residential buildings. However, it is also applicable
for existing buildings designed in accordance with
the IGBC Green Homes criteria.

Gold 52 - 59 70 - 79 National Excellence
Platinum 60 - 75 80 - 100 Global Leadership
Different levels of green building certification are awarded based on the total credits earned.
However, every Green Home should meet certain mandatory requirements, which are non-
negotiable.
The threshold criteria for certification/pre-certification levels are as under:
Validity of Precertification
IGBC may carry site visit anytime during its construction till Certification. The
precertification rating is valid for 3 years from the date of precertification.

13. Case Study
Cygnus World School, Vadodara, Gujarat
Cygnus World School at Vadodara for Jan-Priya Trust, Delhi is
our country’s 1st PLATINUM rated, green building,
conceptualized by Ar. Prem Nath of Prem Nath & Associates,
having more than 1.8 lakh square feet of school complex spread
over 5 acres of land; The school has been planned to cater to all
modern requirements of education; Yet the overall aesthetics of
the school structures shall project a ‘Contemporary’
architectural feel – giving it a elegant campus look.

14. DESIGN
 Planning concept for the project has been
kept simple and practical; the campus has been
mainly planned with Two Zones- Education Zone
& Sports Zone.
 The site surroundings shall be laid with a lot
of Green-Scapes;
 Campus common areas along with driveways &
walk ways shall be laid with paver tiles/blocks;
 Each room is designed in module of 8M x 8M –
providing a standard size requirement of a class
room for 30-35 children and a flexibility to
multiply or divide the module for larger halls for
laboratory or a toilet block, etc. respectively;
 Staircases, toilet facilities, etc. have been provided
as per the required norms & mandates;
 Facilities such as; Medical department including
Distilled and RO water system have been provided
keeping in mind the health of the students as well
as the faculties
 The systems are planned with Green building
concepts in mind – highlighting eco-friendly nature
of running systems
 Each school blocks are North-South oriented
and multiple internal courtyards have been planned
to enable building to breath from within
 Every class room is planned with Ventilators above
Windows and Doors– keeping the internal area well
ventilated and cooler than outside ambient
temperatures
 Class room is placed in a way to Advantage with
Maximum North Light; while provided with large
windows facing North and two entrance doors on
Southside passage
 vermiculite plasterfrom inside and tile cladding
from outside add to the heat insulation of Fly Ash
Brick Walls
 Terrace Tops have been laid with heat insulating
layer & then are fixed with White Glazed Tiles –
reflecting back all the heat;

FEATURES

15. GREEN MATERIALS
 Fly Ash Bricks for Masonry and Vermiculite
Plaster for Internal Plaster – adding value to heat
insulation
 Ceramic reflective Tiles cladding to external
surface & Glazed tiles on terrace tops – adding
value to heat insulation
 Low VOC Paints & Sealants keeping the
environment healthy
 Natural Stones pebbles, marble, granite, etc. for
various landscape features;
 Large Landscaped spaces, incl. wide courtyards
and central green zone between blocks – adding
further value a large patch of Green/Lawns which is
itself approx. 20% of total land area – adding to a
lot of healthy inhibition of internal spaces
 Rain Water Harvesting & Sewage Treatment
Plants enabling use of more than 75% water for
flushing and landscaping
 Solar Panels of approx. 7.5% (60KW) of the total
electricity consumption – enabling substantial
power saving and backup
 Water by virtue of STP & Rain Water Harvesting, topped
with water saving features enables a daily saving of 75% to
80%
 Electricity is one of the most important factors – saving by
vitue of planning a Non-Air-conditioned building itself add
to 35%+further other energy efficient features add to 15% to
20% of saving
 Installation of Energy Friendly Lamps, viz. T5 Tubes, CFLs
and LED Lamps – has enabled power saving upto 20% than
the routine usage
 Solar Panels (60 KW) add to the power saving by about 7%
to 8%
 Installation of Energy Friendly Lamps, viz. T5 Tubes, CFLs
and LED Lamps – has enabled power saving upto 20%than
the routine usage
 Water Saving Faucets and sensor controlled urinals too have
enables a lot of water saving
 Use of FRLS Cables and compact / dry type
Transformers too enable a lot of energy efficiency

16. PLATINUM RATING FOR GREEN SCHOOLS
This is an IGBC’s Pilot project having awarded LEED Platinum Rating for Green Schools
– First ever rating awarded to a school project in India; – and has scored 86% which is
quite high – there are no immediate plans to add any further feature – however the school
management keeps working towards Green Education and plans various awareness
programs;
No Stone Was Left Unturned
The final & lasting impression of this School shall be of a Contemporary Indian School,
Technologically Well Equipped, and drawing from the Best Architectural Practices from
Around The World.
