The Challenge

With a revenue 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 across their facilities.

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 number of employee complaints, which the FM team spent most of their time responding to; and b) energy wastage and high energy bills.
