How to calculate the lighting load & power load requirement
by knowing area of building/room. Is there any thumb rule?
Answer Posted / ramesh
the lighting load is decided not just by the size of the
room but by considering various other factors like the
illumination level requiredin the room, which can theb
converted into electrical power by back working the number
of lamp and the lumens per watt of that chosen type of lamp.
As regarding power load, what i understand is it consists
of airc-conditioning. The thumb rule is 1.5 tonnes of air-
conditioning is required for a room of size say 10 ft x 10
ft x 10 ft. Normally 1.0 tonne ac plant will consume about
2.0 kw max. A 165 litre capacity domestic refrigretaor may
consume about 0.2 kw
For the other power loads like gadgtes (may be xerox
machine at office, computers, printers etc.,) we have to
sum up the actual name plate ratings.
