What is Sub-Metering
Sub-metering, also referred to as suite metering, uses meters to measure the electricity consumption (as well as other commodities such as water) of each individual unit in a multiresidential building (i.e., apartments and condominiums), as opposed to a bulk meter for the whole building. In bulk metered buildings the occupant has no accountability for their electricity consumption.
There are many benefits to sub-metering, both for occupants of the units as well as for building owners, property managers and condominium corporations. Electricity sub-metering allows occupants to take control of their energy use with access to accurate and detailed information of their consumption allowing them to understand, monitor and conserve.
Electricity is typically a building's largest utility expenditure and sub-metering enables significant cost reduction with potentially little to no upfront costs for the building.
