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.

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.
DESIGN ASPECT
BUILDING ENVELOPE EFFICIENCY
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.
PARKING 392 kWp car port solar PV on top of parking building
CONSTRUCTION ASPECT
MATERIAL & TECHNIQUE
EFFICIENT HEAT TRANSFER MODE AND MEDIUM
Water has 3400 times higher heat carrying capacity than air for the same volume
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
2.6 million sqft area covered with white roof About 5% reduction in HVAC energy
Reduces building heat gain and urban heat island effect
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
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.
SERVICES Water Positive strategies
•100% Water sequestration
•Zero Discharge campus
•Low flow fixtures
•Gravity based systems
•100% recycling
–Flushing
–Air conditioning
–Gardening
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
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 airconditioning systems.
•All buildings have dual piping systems for fresh water and recycled water.
Sewage treatment plant with MBR technology
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 Artificial rain water harvesting pond
Ground water recharge
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 .
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 only CFL Crusher Biogas Plant for food waste PET to Polyester
1 ton food waste produces INR 6400 worth LPG
8 PET bottles produce 1 t-shirt
Separates mercury, plastic & glass
