Dear Sir
I am involved in a 5-storey building. The base building loads are mixed loads, i.e the loads include lighting and small power. The DB ( distribution board) has HVAC equipment loads ( air handling units) and also other loads like lifts. The contractor is not willing to provide separate meters for lighting and for plugged loads, and at the same time, the project the project team wants to get points for this. How should we go about. Some DBs contain pumps loads and also lighting loads together

You need to gather the data you need to calibrate the energy model. This usually requires the separation and measurement of each major energy end use. Having mixed boards makes this harder for submetering. You always have the option of figuring out how to gather the data you need by had with spot measurements and short term trending. The bigger the building the more labor intensive this becomes post-occupancy.
I can't tell you the best way to do this but having mixed boards you are already off to a bad start.
