[QUOTE="Manator, post: 337691, member: 9561"] I would guess that you are after a calculation as to total usage and then alternative reduction methods? A good start as with al,l is a measure over a period of time and not instant measurements, this will show the times that the power usage is at its optimum. Then you need to asses where this power has gone to, and how you can reduce this. With Hotels the main power outage is always the lighting. Simply complying with HSE laws means that some lighting, recently badly designed, are still in use providing full lighting 24/7. New methods introduce dimming associated with motion detectors to provide a more efficient lighting system, some even use the computerised Dali system and are programmable from a simple remote. The three phases should be balanced, asd the power quality should be monitored. A simple reduction from say 243v to 230v could save a hotel a fortune! [/QUOTE]
