Firstsource Solutions THE CHALLENGE
CASE STUDY

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 andenergy 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 toimprove energy efficiency in their facilities.
It was important to the facilities team that they resolve their comfort issues withoutcompromising on energy efficiency; a solution they were struggling to find until they met
the team from 75F.

Firstsource Solutions CASE STUDY

Improving comfort & productivity while saving onenergy

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.

THE 75F SOLUTION

THE RESULT

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

Firstsource benefited from an extremely fast, non-intrusive installation, ensuring
minimal disruption to the workforce. Facility managers at Firstsource can see realtime data for each system, making diagnostics as easy as grabbing a mobile phoneor a laptop (instead of populating and referring to lengthy excel sheets). Finally, theemployees at Firstsource now enjoy consistent temperatures at all times making
them more productive, comfortable and healthier, all while the company is savingenergy.

75F’s solutions collect 650 data points every minute and transmit the data to thewireless 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 geographicalorientation to determine the best control strategy. The system learns the building
such as occupancy patterns, the angle of the sun, etc. thereby eliminating the needfor manual intervention and control.

Energy Efficiency & Cost Savings
75F’s solution at Firstsource achieved 45.63% on the AHU energy consumption
while optimising the comfort of the occupants. These savings were realised by:
1. Optimized AHU operation via VFD, based on occupancy, zone temperatures,operation schedule, ambient conditions, etc.

Smarter Facility Management
The 75F solution was easily installed within 3 days, thereby causing minimal disruption
to employees.
The Facilisight platform provided FSL’s facility team with actionable alerts, diagnostics,
remote controlling, temperature trends, energy consumption trends, Real-time Heat
map etc.

Quick Payback
75F’s smart technology is enabling FSL to make better use of their resources. Lower
installation costs and massive savings from reduced energy use will result in a ‘Returnon Investment’ of 2.05 years.
In addition to saving on energy and lower installation costs, FSL also stands to gainfrom increased employee productivity and savings through automation, reduced
equipment wear and tear.

I found 75F’s technology was much superior compared
to any other company that I met. They understandtechnology very well, and they are a very agile team.
