OWNERSHIP & BILLING
Split Systems (1 to 1)
An individual air cooled split system serving each apartment allows ownership of the apartment air conditioning system to be transferred to the apartment owner / investor / occupier, who is then responsible for their air conditioning system’s energy consumption, maintenance, repair and eventual replacement, with minimal involvement required by the development’s body corporate.
Each individual air cooled split inverter system is connected to the associated apartment’s metered electrical distribution board, with the energy consumed included in the apartment’s overall electrical energy consumption. The apartment owner / investor / occupier is required to enter into a negotiated energy supply and billing arrangement directly with the apartment owner’s / investor’s / occupier’s electrical energy distributor of choice, and not with the body corporate.
