Lighting:
Total No. of Fluorescent Tube lights = 20 nos.
Average Power saved per bulb = 26 W
Total Power saving = 20 x 26 W
= 0.52 kW
Average Use of bulbs per year = 320 x
12h = 3840h
Total Energy saved per year = 3840 x 0.52 kWh
= 1996.8 kWh
Saving in Rs. Per year = Rs. 1996.8 x 5.3
= Rs. 10583
Average Cost of Replacing bulb = Rs. 180
Total Cost of Replacing all bulbs = 20*180
= Rs. 3600
Capital Cost Recovery time = (3600)/(10583)
= 0.34 yrs.
= 4 months
ENERGY CONSERVATION
SUGGESTIONS
Put UPS of sufficient capacity for uninterrupted power supply
Replace existing 40W tube lights with 14W CFL.
Replace inefficient under loaded motors with new energy efficient motors.
Give sufficient maintenance and lubricate rotating gear parts properly to avoid
losses
Replace old conveyer belts with new ones
Provide APFC so that overall power factor can be improved.
Use transparent sheets to use day lights and reduce lighting load at day time.
Replace existing CRT monitors with LED monitors in office.
