Dear all,

We have a tower with multi-storey building, made up of 3 components: Offices, hotel and residential. We follow as a reference the " BD+C NC "

The metering will be separate: Each component will be equipped with its own  meters (because we will have different operators).
So how do I install the meters? I need to install advanced meters:
1. for any individual end use of energy which represents at least 10% of the total annual consumption of the building (consumption sum of offices + hotel and residential )?
Or
2. for any individual end use of energy that represents at least 10% of the total annual consumption of each component?

As well,
the meters must read the electricity consumption (Kwh) or the KW? we are lost!!!

We will appreciate your return,
