Assess NCC 2025 Section J energy efficiency by climate zone - fabric, glazing, HVAC, mandatory solar PV and EV provisioning.
Select the climate zone and building class and the Section J tool sets out the NCC 2025 requirements: building-fabric R-values, glazing ratio, U-value and SHGC limits, HVAC efficiencies, lighting power densities, mandatory solar PV and EV-charging provisioning, and condensation management.
It also estimates the additional cost of meeting NCC 2025 over the NCC 2022 baseline, highlighting where the 2025 provisions have increased.
The Section J Energy tool is a professional aid. Verify all outputs against the current National Construction Code and the relevant Australian Standards, and have them certified by a suitably qualified practitioner before use.
Determine the Bushfire Attack Level per AS 3959:2018 from vegetation, distance and slope - using your state’s Fire Danger Index.
Determine every required fire system for any building - each with its NCC clause and a rough order-of-magnitude cost estimate.
Look up tested fire-rated construction systems that meet or exceed a required FRL.
The Section J Energy tool is built around NCC 2025 Section J, with the relevant clauses cited on every output. Always verify results against the current National Construction Code and Australian Standards.
