Utility sub-metering is a system that allows a landlord, property management firm, condominium association, homeowners association, or other multi-tenant property to bill tenants for individual measured utility usage.[citation needed] The approach makes use of individual water meters, gas meters, or electricity meters.
Sub-metering may also refer to the monitoring of the electrical consumption of individual equipment within a building, such as HVAC, indoor and outdoor lighting, refrigeration, kitchen equipment and more. In addition to the "main load" meter used by utilities to determine overall building consumption, submetering utilizes individual "submeters" that allow building and facility managers to have visibility into the energy use and performance of their equipment, creating opportunities for energy and capital expenditure savings.
