Manipal University Jaipur has been awarded LEED Platinum Certificate & Green Rating for Integrated Habitat Assessment (GRIHA) award for water management.
3. INTRODUCTION
Manipal University’s Jaipur campus is being designed to be a LEED Platinum and GRIHA 5 star
rated project. When completed, the campus will accommodate 20,000 students and will have an
engineering college,a medical college and facilities for postgraduate studies. It will also house
administrative buildings, state of the art research facilities, workshops, labs, library, and
residential facilities. Terra Viridis is working on this project as green building consultants
assisting the architects in integrating passive design strategies such as improved day lighting,
optimizing external shading solutions, better natural ventilation, maximizing mixed mode
ventilation and night cooling, etc. with the objective of making the campus significantly
comfortable in the otherwise harsh weather of Jaipur while ensuring maximum energy
reduction.

5. 1) SUSTAINABLE SITE PLANNING
Landscaping planned to minimize urban heat
island effect based on Irradiation and Wind
Studies
Swales and wetlands designed for 100% recharge
of rainwater
Almost 95% of construction waste reused or
recycled
6. Hostel Planning
The conceptof these hostels is to keep it low rise, dense and organic, to
take advantage of the environmental benefits of local vernacular
architecture.
Several irradiation mapping and wind analysis studies were undertaken to
ensure all the courtyards and alley ways were shaded to a great extent so
that they can act as‘cool air ponds’.
Importance was given to comfort at pedestrian level by ensuring cool
shaded courtyards,corridors and alleyways with slight breezes.
Wind analysis helped in creating a network of enclosed courtyards with
carefully located corridors that will allow for cool breezes to flow through
in midseason and winters while keeping the harsh hot summer winds out.
Different shading devices were designed for different levels and
orientations that helped in adding interest to the facades.
7. 2) Reducing Water Consumption
Use of low-flow fixtures and fittings help reduce
building water use by as much as 59%
Extensive use of native trees and shrubs along with
drip irrigation and micro sprinklers help reduce
landscape water use by as much as 84%
100% tertiary treatment of waste water and 100%
reuse of treated waste water for flushing and
landscaping
5000 PLANT AND TREES ARE PLANT THAT HELP IN
FILTER AIR.
8. Rainwater Harvesting

9. 3) Reducing energy consumption
It Reduce consumption of energy(compared to GRIHA benchmarks) while
maintaining occupant comfort.
For Achieving Visual Comfort:
All fenestration designed to provide glare free usable daylight in most areas
As this is a daytime use building, it has been designed to run only on daylight.
Most of the spaces run on daylight throughout the year. (Spaces designed to
achieve daylight levels of about 150lux)
Projectors in the classroom have been selected to work with the available daylight
so that blinds could be avoided.
10. For achieving thermal comfort
All rooms have buffer spaces outside in form of corridors or jalis in order to reduce
solar gains into the rooms and maximise comfort
Optimized shading based on orientation in order to provide complete shading in all
spaces throughout the year while maximizing daylight.
GRC jalis used on the East and West facades to maximize shading
High performance selective used to reduce solar gains further
Different types of glazing used in different sections based on shading and
to ensure a balance between daylight and solar gains
Number of openable windows calculated based on use and orientation of each
Low level and high level openable windows provided on both sides of the rooms to
both cross ventilation and stack ventilation
Double wall with insulation in the cavity provides both thermal mass and insulation
maximize thermal lag
Reducing energy consumption
11. For energy efficiency
Designed for Mixed mode ventilation, with natural ventilation in winters, and
evaporative cooling in summer (in academic block)
HVAC system designed to provide free cooling in winter
Chiller efficiency further improved by providing evaporative cooling pads
them
100% LED lighting across campus » Occupancy and daylight sensors provided in
all classrooms and faculty rooms.
Reducing energy consumption
12. Use of low energy materials
16.6% reduction in structural steel and 15.2% reduction in
structural concrete by quantity was achieved by using efficient
building technology.
Use of hollow concrete and AAC blocks for better insulation and
lower embodied energy.
43.3% reduction in embodied energy in non-structural
application from GRIHA base case.
13. SYSTEM USED
