Total renewable energy procured in FY21 is 11.46 million which is 94% of the total electrical units resulting in reduction of approx. 10,738 tons of Carbon footprint (estimated figure, certificate is delayed due to lock down)

Total 25 number of air handling units (AHU) installed with VFD to reduce the power consumption

Zero down time STP plant operations in FY21

Efforts taken towards recycling waste
1)Water is recycled for usage in flushing and cooling tower for condenser water requirement.
2)Organic Waster Converter (OWC) to convert the organic waste from F&B outlets to a soil supplement, which is used in landscaping.

Greenhouse gas emissions 1)Mall team tracks Diesel Generator Effluents and ensures the same is within recommended parameters.  

Energy conservation steps taken are as follows:
1)New energy efficient Variable Frequency Drive (VFD) screw chillers to replace the old reciprocating chillers.
2)New Primary variable pumping systems to replace the old primary and secondary systems.
3)Pressure Independent balancing Control Valves (PIBCV) Actuator Valve sets in the Chilled Water Systems to reduce the energy consumption
4)Managed chillers with set points based on time of the day and weather.
5)Common area lighting integrated on building management system (BMS) for optimised usage and saving energy.
6)Use of new Energy Efficient Transformers
7)Replaced CFL with LED Lamps

Water conservation steps taken are as follows:
1)Dual Flow flush to reduce the Water used per flush.
2)Rainwater is used for flushing and cooling tower requirement.
3)Sewage treatment plant (STP) water is used for flushing and cooling tower requirement.

Conversion To Manure From Wet Garbage:
1)100% wet garbage collected at the mall is converted into manure and used for gardening and farming. The equipment installed by the mall ensures faster decomposition.

E-Waste:
1)Recycled 475 Kg E-waste in FY 20-21 through Maharashtra Pollution Control Board (MPCB) authorized vendor.
2)Obtained E-waste recycling certificate from the vendor

Waste Oil:
1)Recycled 590 Ltr old Diesel Generator (DG) set oil in FY 20-21 through MPCB authorized vendor.

Chemicals:
1)No chemicals being used since installing electrolytic cooling tower water treatment system for HVAC cooling tower.

Water conservation Initiatives/Savings:
1)Natural ground water discharged has been taken into treatment plant and used for domestic purposes.
2)Floor wise water pressure throttled as desired flow for flushing.
3)Water inlet vs outlet to STP has been audited and leakages arrested.
4)STP efficiency enhanced from 85% to 87%.
5)Recycling of waste water by STP treatment and this STP water is utilized for toilets, gardening and HVAC cooling tower requirement.
6)Rain water collected from open courtyard (Liberty Square) area and used for flushing and gardening purpose during monsoons.

Solid waste generation and management:
1)Wet Waste: The actual generation of organic wet waste on an average is 384 tonnes/year i.e. 1,051 Kg/day. The same is being recycled in the OWC and manure generated is being used for landscapes within the property.
2)Dry Waste: On an average 1.5 tons of dry waste per day is being handed over to the GCC (Greater Chennai Corporation) authorized garbage management vendor for disposal to designated garbage disposal sites.

Sustainability efforts & contribution:
1)Efforts taken to recycle wet waste received through OWC system and effective distribution of Composite for landscaping across the property.
2)Property being zero discharge, efforts taken to recycle raw sewage to treated water and utilize for flush system, AC Cooling towers, landscaping etc.
3)Stack emissions, ambient air quality (Indoor and Outdoor) is monitored at regular intervals and efforts are being taken to maintain the parameter below the prescribed limits defined by compliance authorities.
4)Ozoniser installed in STP to minimize H2S levels in the exhaust system.
5)Calibration of DG fuel system being undertaken on a half yearly basis to determine the amount of unburnt fuel content in the Stack emissions.
