In this case the tenant has a contract with the utility company and pays for his electricity. But the base building provides chilled water and this cost is included in the base rent.

Can we comply only with the contract with the utility company?

Or do we also need to make two payments to the owner, one for rent and one for the energy provided? If this is the case, how should the owner determine the amount to be charged? The owner doesn´t have submetering, he only knows the basebuilding total consumption.

Thanks
