Hi to all,

We are just starting to certify an existing Core and Shell office building. It´s been hard and complicated to get the electricity bill from every single tenant (they all have an independent electricity meter), but we do have the metered energy consumption from the whole building (including common spaces as well as tenant spaces) since the building has a master electricity meter, so we have any indicator that we might need (power, energy consumption, power factor, reactive power, etc.) for 15 minutes intervals.

Can we use that record for energy purposes, or should we ask for each and every electricity bill of the tenants?

Id appreciate your help.
