Green internal IT TCS has undertaken a series of initiatives to reduce
the energy footprint of our data centres and
computer workstations, such as server virtualization
and consolidation, server cooling load management,
shift to blade server, procurement of energy-star
rated equipment, remote desktop control, etc.
Pilot desktop virtualization projects are underway to
help reduce the energy consumption further by
consolidating individual CPU loads on a single server
for load optimization.
Energy audits TCS has taken up the internal energy audit projects at
various locations to identify potential energy
efficiency projects to come up with all possible
innovations and ideas to improve the energy
performance of the older buildings.
Operational energy efficiency Operational controls that have been put in
place include:
n Switching on the AC half-an-hour late every
morning and turning it off half-an-hour earlier in
the evening
n Regulating temperature in a close band (24+1o C)
n Replacing tube-lights with CFL luminaries and LED
for common areas
n Installing Variable Frequency Drive in air handling
units

n Capacitor Bank Power Factor Management
n Putting solar PV based peripheral light system
n Minimizing use of halogen and other energy
intensive lighting
n Switching off of monitors when not in use through
central programming
n Employee Engagement through awareness drives
and putting up posters etc.
