L&T INFOTECHCASE STUDYREMOTE MANAGEABILITY, ENERGY SAVINGSAND OPERATIONAL EFFICIENCY AT INDIA’S 4TH
LARGEST I.T. COMPANY

THE BACKGROUND
LTI (Larsen & Toubro Infotech) is a global IT services company headquarteredin Mumbai and is ranked 4th among Indian companies in 2018. With arevenue of over $1 Bn and over 25,000 employees, it is no surprise that they
showcased the same level of commitment towards sustainable technology,
seeking to provide the best working environment for employees acrosstheir facilities

During its site survey, 75F noted an opportunity to save substantial amountsof energy via predictive, proactive automation of LTI’s HVAC & Lighting
systems thereby bringing in operational efficiency and remote visibility.

LTI CASE STUDYWhen LTI Bengaluru’s Facility Lead, Mr Kishore Kumar was introduced to75F India by a partner, he says he was ‘floored’ by the technology. “75F
demonstrated over 55% savings while giving my team the comfort ofautomation and remote manageability,” says Kishore when asked about
his reasons for hiring 75F. The challenges facing the facility team at LTI
Bengaluru were primarily two-fold: a) lack of automation for the HVAC& Lighting system leading to hotspots & coldspots and a high numberof employee complaints, which the FM team spent most of their time
responding to; and b) energy wastage and high energy bills.

THE RESULT

THE 75F SOLUTION
After a successful pilot at LTI, 75F installed Dynamic Chilled Water Balancing Solution,
Energy Management System and Advanced Lighting Solution at LTI. Facilisight, 75F’ssuite of web and mobile apps, that facilitates easy monitoring and control withpredictive proactive automation was also included.
Dynamic Chilled Water Balancing Solution: 75F deployed an end-to-end solution
for LTI’s chilled water system to maintain comfort while using less chilled water andsaving more energy. 75F sensors in each zone directly communicate with the Central
Control Unit (CCU) – giving LTI’s FM team the ability to monitor the inlet and outlet
temperatures, chilled water flow rates and BTU energy consumption across the line.
Energy Management System: 75F sensors across workstations provide an overviewof the real-time temperatures on the floor. 75F’s system automatically modulates theVFD based on inputs from these sensors, the set-point temperature and the coolingdemand in order to maintain optimal comfort at all times while saving energy.

The 75F solution at LTI delivers over 55% savings on HVAC and lighting energy
bills each month. Thanks to the automation of the entire HVAC and Lighting
system at LTI, the facility team has also noticed a marked improvement in theiroperational efficiencies; reducing the time spent on responding to employeecomplaints and improving the team’s productivity. Facilisight has provided theteam with greater insight and control over the HVAC system in the facility.
They are now able to monitor and control energy usage in real-time remotely.
At the same time, the employees at LTI are happier too. The building is being
conditioned without human intervention thanks to the predictive powerof 75F proprietary algorithms. The number of complaints logged in about
uncomfortable temperatures has gone down considerably.
The delighted FM team at LTI plans to continue working with 75F for a seriesof roll-outs, starting with their Chennai office.

Advanced Lighting Solution: 75F’s Advanced Lighting system considers many factors
about the building such as weather forecasts and location of the building alongwith real-time factors such as occupancy, scheduling, user preferences, etc. before
determining the ideal time to adjust the lighting gradually.
75F Facilisight: Facilisight provides the facility team at LTI multi-site visibility
and insights into HVAC and Lighting energy consumption. Besides automaticallymonitoring, managing and controlling these systems proactively, 75F also provides
the FM power to control their buildings at a click.

The FM team gains visibility and control over their facilities remotely.

It’s a very innovative solution. Earlier, the team spent a lot of time
responding to comfort related complaints and taking hourly readings
but now thanks to 75F our productivity has improved greatly.
