About The Customer

Larsen & Toubro Infotec (LTI) is a global IT services company based in Mumbai. It is ranked 4th among Indian companies in 2018 and boasts a revenue of over $1 billion. The company employs over 25,000 people and is committed to sustainable technology, striving to provide the best working environment for its employees across all its facilities. LTI Bengaluru’s Facility Lead, Mr Kishore Kumar, was introduced to 75F India by a partner and was impressed by the potential energy savings and automation capabilities of their technology.

The Challenge

Larsen & Toubro Infotec (LTI), a global IT services company, was facing two primary challenges at their Bengaluru facility. Firstly, the lack of automation for their HVAC & Lighting system was leading to uneven temperature distribution, resulting in numerous employee complaints. The facility management team was spending a significant amount of their time addressing these issues. Secondly, the company was dealing with high energy wastage and consequently, high energy bills. During a site survey, 75F, an IoT solutions provider, identified an opportunity to save substantial amounts of energy through predictive, proactive automation of LTI’s HVAC & Lighting systems, which would also enhance operational efficiency and remote visibility.

The Solution

75F implemented a comprehensive solution at LTI, which included the Dynamic Chilled Water Balancing Solution, Energy Management System, Advanced Lighting Solution, and Facilisight. The Dynamic Chilled Water Balancing Solution involved an end-to-end solution for LTI’s chilled water system to maintain comfort while using less chilled water and saving more energy. The Energy Management System used 75F sensors across workstations to provide real-time temperature data, which was used to automatically modulate the VFD for optimal comfort and energy savings. The Advanced Lighting Solution considered various factors about the building and real-time factors to determine the ideal time to adjust the lighting. Facilisight, a suite of web and mobile apps, provided the facility team at LTI with multi-site visibility and insights into HVAC and Lighting energy consumption, enabling them to monitor, manage, and control these systems proactively.

Operational Impact

The implementation of 75F's solution has resulted in marked improvements in operational efficiencies at LTI. The automation of the HVAC and Lighting system has significantly reduced the time spent by the facility team on responding to employee complaints, thereby improving the team’s productivity. The team now has greater insight and control over the HVAC system in the facility, with the ability to monitor and control energy usage in real-time remotely. Additionally, the building is now conditioned without human intervention, thanks to the predictive power of 75F proprietary algorithms, leading to a significant decrease in complaints about uncomfortable temperatures. The facility management team at LTI is so pleased with the results that they plan to continue working with 75F for a series of roll-outs, starting with their Chennai office.
