• Note:


• In all load centers, cable cellars & related rooms, Illumination on 24 hours in
  a day continuously, considering 3 hours’ average Occupancy in a day,
  remaining time, lighting fixtures should kept off & only emergency lights
  should be on, by using Occupancy sensors on load centers, we can save
  huge energy.


• Saving for all Load Centers: Rs. 7,14,616/- Per Annum


• ROI Calculation:


• Pre Heater Building:
  At pre heater, from ground floor to top floor, Illumination on for 12 hours in
  a day from remote, we can save energy by using Occupancy sensors on
  ground floor with interlocking with other floor, so that, whenever, anybody
  will go for any work on Pre Heater building, he will switch on & perform
  work, considering 1 hours every day inspection in night hours basis, we can
  switch off 330 hours in a month for energy saving.
