Tenant Metering Solutions from CETA

For Tenant billing, the application of Pattern Approved Metering products helps with regulatory compliance. The installation of electricity sub-metering is mandatory at the time of construction of a new building. It is not applicable when undertaking renovations or additions to existing buildings. To comply with the QDCs acceptable solutions, the electricity sub-meter for each unit or storey must be located in a common area (e.g. foyer, shared car park). It must also be in a place that is easily accessed by the person that is authorised to read the meter (e.g. electricity retailer, body corporate). For example, sub-meters located inside a unit that only tenants can access would not comply.

The Building Code of Australia 2010 also introduced mandatory sub-metering provisions for class 2 and 5 buildings from 1 May 2010. This includes requirements for sole-occupancy units (e.g. a room or a suite of rooms in a building) in class 2 and 5 buildings over 500 square metres in floor area to be sub-metered for electricity. However, the requirement in QDC 4.1 for sole occupancy units to be sub-metered for electricity applies regardless of the building’s size. In a situation such as this where the Building Code of Australia is inconsistent with QDC, the requirement under theQDC prevails to the extent of the inconsistency.For class 5 buildings where the total floor area is over 2500 square metres, the Building Code of Australia 2010 provisions also require other parts of the building to be sub-metered, such as the air-conditioning plant, lifts and the central hot water supply. For class 2 buildings, the same provisions apply, but only if the common areas are more than 500 square metres and the total floor area is over 2500 square metres.
