Electric power factor within SBEM must be left at the default value of <0.9 unless you have provided aphotograph of the power factor correction device and/or other compelling evidence to amend this figure.
Where only a photograph of the power factor correction device is available the power factor shall beamended to ‘0.9 to 0.95’.
Compelling evidence includes the following:-
• Photographic evidence; if the photograph can confirm the actual power factor figure from the device,then select the most appropriate figure within the SBEM power factor drop down options. If thephotograph cannot confirm the actual figure but shows evidence of the power factor device, then theassessor shall select the option of ‘0.90-0.95’ within SBEM for the power factor value.
• Equipment specifications; name-plates, specification manuals and printouts from BuildingMechanical Services (BMS) systems.
• Utility bills.
• Power factor calculations; conducted by electricians and power engineering specialists.
• Meter readings; incorporating reactive unit consumption and appropriate calculations.
