SDG IMPACTED
The environment has a direct impact on the health and well-being of every stakeholder in our value chain. It is therefore important that we strive to mitigate our own impact, and wherever possible, influence positive environmental practices.
We believe in improving and maintaining ecological balance by monitoring, measuring, and controlling environmental impact at our workplaces by adopting technologically sound and sustainable practices. Our commitment towards the environment and society has been integrated into our operations to ensure sustainable development.
We prioritize energy efficiency throughout our processes, from effectively utilizing our energy sources to reducing our carbon emissions and waste. We continually monitor our energy consumption to ensure efficient resource management.
Our approach to energy efficiency involves two strategies: 1. Promoting behavioral changes among our associates to encourage energy conservation and 2. Smart management of lighting, heat ventilation, and cooling, and integrating energy efficiency into our overall operations through design considerations and operational practices.
KEY INITIATIVES IN FY24
REPLACEMENT OF R22 GAS UNITS WITH ECOFRIENDLY REFRIGERANT UNITS
- In Bengaluru Global Village facility Phase 1 & 2, split AC units were replaced with variable refrigerant flow (VRF) system for effective cooling. The VRF system responds individually to fluctuations in space load conditions and since this is a ductless system, it helps in saving energy from leaking or unprotected ducts.
- We were able to achieve significant energy savings by allowing the HVAC motors to operate at required speeds based on the load requirement instead of running them constantly at a fixed speed. The VRF system can heat and cool different zones at the same time within the set range as per demand, allowing workers and sensitive equipment to stay safe. To phase out R22 completely, R410a is being used as a refrigerant, which is more environmentally friendly than R22.

OPTIMIZATION OF UPS
In our Hyderabad Raheja facility, we have reduced the installed UPS capacity by 33% from 240 KVA to 160 KVA. This reduction in capacity not only leads to energy and cost savings, but also helps to minimize the need for replacements and associated expenses. The initiative led to cost savings of INR 13.95 Lakh per annum (including battery replacement and AMC charges.
ENERGY SAVINGS AS A RESULT OF REDUCED UPS CAPACITY
We have similarly reduced UPS capacity at the Pune Hinjewadi campus from 320 KVA to 160 KVA after a thorough analysis of the load pattern over the past two years and future projections. Apart from energy and cost savings, the step has minimized the need for replacements and associated expenses. The initiative led to a cost saving of INR 19 Lakh per annum (including AMC, AC capacitor replacement, energy savings, and buyback), resulting in an ROI of 12 months.
ENERGY SAVINGS RESULTING FROM UPS CAPACITY REDUCTION IN PUNE
INSTALLATION OF EC FAN
HVAC systems use electric motors, which consume a lot of energy. An electronically commutated (EC) motor is designed to run on alternating current (AC) power supply. It resembles a direct current (DC) motor and is essentially a permanent magnet (PM) brushless DC motor that incorporates on-board electronics. EC fans are highly efficient and replace all fixed speed drives, belt-pulley AC induction motors in an air handling unit (AHU) assembly. High efficiency also leads to a range of secondary and tertiary benefits. At our Hinjewadi – Qubix office, we have retrofitted one of the AHU units and replaced it with ECM fan drive units. This has resulted in cost savings of INR 90,000 per annum.
ENERGY SAVINGS FROM THE INSTALLATION OF EC FAN
We have committed to run our operations with 85%+ renewable energy use by 2030. To achieve the set goals, we are making continuous effort to increase energy sourcing from renewable resources for our internal operations. As on date, we have 1093.5 kW capacity of solar panels installed within our facilities. In addition, various steps have been taken to procure renewable resources through various schemes such as the Green Tariff scheme, Energy Attribute Certificate (EAC) scheme and Physical PPA scheme.
ENERGY REQUIREMENT MET FROM RENEWABLE RESOURCES
Preserving fresh water is a vital component of our corporate social responsibility, and we continually strive to reduce our impact on the community by adopting sustainable practices. To achieve this, we have integrated the Reduce, Reuse, and Recycle (3R) approach into our operations to ensure minimal freshwater usage. We have also implemented various initiatives targeted at this set objective.
At most of our facilities, water required for flushing, landscaping, and HVAC cooling towers is sourced from recycled water.
At our owned facilities, we have initiated rainwater harvesting and installation of recharging pits to recharge the groundwater level. The reporting period also saw us undertake a host of initiatives to reduce water consumption.

INSTALLATION OF WATERLESS URINAL
At all our Pune facilities and in Bhubaneswar, we have replaced conventional urinals with waterless urinals, which reduce water wastage, thereby helping reduce the overall environmental footprint of the restroom facility, and contributing to a cleaner, greener world. This also helps improve the overall hygiene of the restrooms and reduces the risk of illness and infection. The initiative also resulted in cost savings to the tune of INR 13.67 Lakh per annum.
WATER SAVINGS AS A RESULT OF WATERLESS URINALS
INSTALLATION OF WATER AERATORS
During the year, we replaced existing water aerators with efficient ones in our Global Village – Phase 5 facility. As a result, the flow rate of water aerators for cafeteria and rest room handwash taps reduced from 4 LPM to 2.4 LPM; for pantry taps, the flow rate reduced from 15 LPM to 3 LPM; and for health faucet guns, it reduced from 7.5 LPM to 6 LPM. In all, we have replaced 237 water aerators, which will result a cost saving of INR 5.4 Lakh per annum.
