Firstsource Solutions, the trusted outsourcing partner for world’s leading brands, is known for delivering excellence in customer experience. With employees as their key strength, Firstsource Solutions looks to provide a comfortable, world-class working environment.

However, First source Solutions’ Malad Paradigm office in Mumbai faced significant temperature differences in different parts of the office – which was compromising employees’ comfort and in turn output. The facilities team spent considerable time and energy responding to regular complaints about hot spots and overcooling and were on the lookout for a permanent solution.

At the same time, as a responsible corporate citizen, reducing carbon footprint and being more sustainable is paramount to Firstsource. They embarked on a mission to conserve energy some years ago and are constantly looking for ways to further their efforts to improve energy efficiency in their facilities.

It was important to the facilities team that they resolve their comfort issues without compromising on energy efficiency; a solution they were struggling to find until they met the team from 75F.


Dedicated to offering a comfortable environment to their employees while saving energy, Firstsource Solutions deployed 75F’s Dynamic Airflow Balancing and Dynamic Chilled Water Balancing solutions across their Malad Paradigm facility. 75F installed a variety of automation controls at Firstsource to best suit their layout and needs. The 75F Facilisight suite of web and mobile apps is the central control hub, bringing cloud-based control solutions with remote monitoring, deep analytics and smart automation for optimal control of comfort and efficiency.

75F’s solutions collect 650 data points every minute and transmit the data to the wireless Central Control Unit (CCU), where it is sent to the cloud for processing. 75F’s proprietary algorithms determine the optimum settings for the next day’s strategy, factoring in everything from the local weather to Firstsource’s geographical orientation to determine the best control strategy. The system learns the building such as occupancy patterns, the angle of the sun, etc. thereby eliminating the need for manual intervention and control.

"Since we installed 75F's solution, we've achieved significant savings on our energy bills and have noticed a considerable improvement in comfort levels. Moreover, 75F's solution helped improve the productivity of my team."
