NCC2022 energy efficiency is coming into effect on October 1st, 2023. With its arrival are provisions that will require Class 2, 3, 5, 6, 7b, 8 and 9 buildings to have an allowance for the installation of future electric vehicle charging and renewable energy infrastructure. These outcomes will facilitate easy retrofitting of equipment later down the track. These provisions do not apply within a Class 2 SOU or Class 4 part of a building or to a Class 8 electricity network substation.
Facilities for electric vehicle charging equipment
Carparks associated with the respective building classes mentioned above are required to provide electrical distribution boards (EDB) dedicated to electric vehicle charging. These electrical distribution boards must have the capacity to manage and schedule charging based on total building demand. They will also be sized to facilitate charging at varying capacities depending on the building classification as well as the number of carpark storeys and spaces. See the table below for an overview of the requirements.
Facilities for solar photovoltaic and battery systems
In addition, the main switchboards of these buildings are required to reserve circuit breaker slots for the future adoption of solar photovoltaic and battery systems. Buildings with a roof area larger than 55m2 are also required to dedicate at least 20% of roof space to be left clear for the future installation of solar photovoltaic panels. Exceptions apply where an equivalently sized solar PV system is already installed, or where it may not be practical to install solar including situations where a rooftop is completely shaded 70% of daylight hours.
