all Infrastructure Services from a centralized data centre in Tower A for the entire

Campus.

Result :

UPS energy Saving = 3,91,574 kWh/Year

HVAC energy Saving = 4,38,000 kWh/Year

Total energy saving = 8,29,574 kWh/Year

Total reduction in carbon foot print = 437185 kg

Area saving = 4,000 Sq.ft

Additional Seats = 130Seats

Decommissioned UPS = 2 X 300 kVA

Decommissioned PAC = 6 x 25 TR & 2 x 16 TR
