NCC 2025: Section J I Release Date
NCC 2025 is out. Well in Victoria it is! Other States and Territories are on the waiting list.
And as with most things in this industry, it has arrived with more complexity than any of us were banking on.
Understanding the new provisions takes time. Building reliable automation on top of them takes considerably more. Our full release is tracking for sometime after September, but there's already something worth knowing about.
Part J4 Building Fabric (well Specification 37 at least) is available right now, at no cost. If the 'facade calculator' is your immediate concern, you don't have to wait.
J1V3 is the bigger lift. What's needed isn't a patch on the existing methodology but a more robust and flexible approach. Add some genuinely convoluted PV applications in the reference building and you start to see why September is the honest answer. We'll be testing properly and checking in with the ABCB before anything ships.
