The Infosys campus in Mysore, India achieved LEED Platinum certification for its sustainable design and operations. Some key aspects included efficient building envelopes to reduce energy use, daylighting designs, solar panels, radiant cooling, water recycling systems, waste management programs, and smart metering for energy and water. The campus aims to maximize resource efficiency and minimize environmental impacts through its architecture, construction techniques, and services.

2. SUSTAINABLE ARCHITECTURE
 'Sustainability' concerns the relationship between humans and their natural
environment over time. Sustainability is most often defined as meeting the needs
of the present without compromising the ability of future generations to meet
theirs.
 Sustainable means Causing little or no damage and therefore able to continue
for a long time.
 Sustainable architecture is architecture that seeks to minimize the negative
environmental impact of buildings by efficiency and moderation in the use of
materials, energy, development space and the ecosystem at large.

3. ACHIEVEMENT OF SUSTAINABILITY IN

8. INTRODUCTION
The Infosys Mysore campus has been awarded the LEED EBOM (Leadership in Energy
and Environmental Design - Existing Building Operation & Maintenance) Platinum
certification by the United States Green Building Council (USGBC).
Infosys now has 18.25 million square feet of the highest rated green buildings – of which
16.9 million square feet are LEED Platinum rated and 1.35 million square feet are GRIHA
5-star rated buildings.

9. DESIGN ASPECT
 BUILDING ENVELOPE EFFICIENCY

10.  DAYLIGHT PANELS AND VISION PANELS FOR WINDOWS
 LIGHT SHELVES TO IMPROVE NATURAL LIGHT IN THE WORKING SPACES
• THE WINDOW IS SPLIT INTO TWO TYPES OF GLASS.
• THE UPPER GLASS IS CALLED THE DAY LIGHT PANEL. IT
GIVES NATURAL LIGHT WITH LESS AMOUNT OF GLARE.
• THE LOWER GLASS IS CALLED AS VISION PANEL AND IT
HAS LOW VISIBLE TRANSMITTANCE.
• THIS TYPE OF WINDOWS CONSERVE ENERGY AS THEY
ALLOW LESS HEAT IN THE BUILDING AND ALLOW AMPLE
OF DAY LIGHT.

12. PARKING
392 kWp car port solar PV on top of parking building

13. CONSTRUCTION ASPECT
 MATERIAL & TECHNIQUE

14. EFFICIENT HEAT TRANSFER MODE AND
MEDIUM
Water has 3400 times higher heat carrying capacity than
air for the same volume

15. RADIANT COOLING TECHNIQUE
 75% more efficient than standard
air-conditioning system
 •Requires 80% less air compared to
conventional system
 •Higher thermal comfort on account
of better mean radiant temperature
 •Highest indoor air quality. Requires
less space compared to
conventional system

16. 2.6 million sqft area
covered with white
roof
 About 5% reduction in
HVAC energy
Reduces building heat gain and urban heat island
effect

17. DATA DRIVEN BUILDING OPERATIONS
•Energy saving algorithms optimize operation
•Continuous measurement and verification
•Improves indoor air quality, employee comfort and
productivity
•15% reduction in energy as compared to standard
buildings

18. Smart energy metering and
benchmarking
 •All buildings use smart energy meters and Sub Metering
 •Smart meters communicate on internet and send out data continuously
 •Capability to communicate allows them to be compared on common
platform
 •Collected data from buildings in a city can be used to benchmark building’s
EPI against standards. E.g. Office building EPI in Delhi not to exceed 100
kWh/m2/year
 •Sub-metering to monitor consumption of sub-systems. E.g. Air-conditioning
systems, lighting, computers, etc.

19. Water Positive strategies
 •100% Water sequestration
 •Zero Discharge campus
 •Low flow fixtures
 •Gravity based systems
 •100% recycling
 –Flushing
 –Air conditioning
 –Gardening
SERVICES

20.  Goal : 50% reduction in per capita water consumption
 •Low flow fixtures
 •Dual flush system
 •Waterless urinals
 •Flow restrictors and aerators
 •Pressure reducing valves at building entry
 •Replacement of lawns with low water consuming native plantation
 •Root zone irrigation
Aerators
Dual flush system
Per capita fresh water requirement for commercial buildings not to exceed 15 liters per day

21. 100% of the water to be recycled and
reused
 •Practice zero liquiddischarge policy.
 •100% of waste water is recycled through in campus
stps with ultrafiltration/membrane bio-reactor (MBR)
treatments.
 •Recycled water is used for irrigation,flushing and air-
conditioning systems.
 •All buildings have dual piping systems for fresh water
and recycled water.

technology

22. Zero discharge campus for rain water
 Roof top water is collected locally and sent to water treatment plants or sequestered
in the ground via borewells
 •Groundwater is collected in ponds
 •Goal is to sequester more freshwater than we consume
Roof top rain water harvesting Ground water recharge
Artificial rain water harvesting pond

23. Smart water metering and benchmarking
 •All types of buildings and homes to use smart watermeters
 •Smart watermeters can communicate on internet and send out data
continuously
 •Automated water balance to identify unaccounted
water.(leakage,theft,measurement error)
 •Collected data from buildings in a city is used to benchmark building’s water
performance index (WPI) against standards.E.g. (Office building WPI in Delhi
not to exceed 25liters /person/day)
 •Provide all water consumption data on the cloud and allow users to compare
their consumption with others and with benchmark numbers
 •Sub-metering to allow comparison of sub-systems.E.g.Water for domestic
use,recycle dwater,water for air-conditioning systems .

24. Waste management
Aim towards Zero Waste to Landfills
 •Organic waste : All organic waste generated, to be treated on campus (No
organic waste to go out of campus)
 •Inorganic waste : All non-hazardous dry waste to be handled by authorized
recyclers to ensure zero disposal to landfills
 •Hazardous waste: All hazardous waste to be handled by authorized vendors
