Queensland stays on NCC 2022 until 30 April 2027. This guide covers what Section J requires today, what NCC 2025 changes from 1 May 2027, and how to plan a project that straddles the date. Checked 1 November 2026.

In Queensland, all NCC 2022 provisions remain in force until 30 April 2027. NCC 2025 is adopted and has legal effect from 1 May 2027, and any amendments to NCC 2025 are adopted after that date. The ABCB notes that section 37 of the Building Act 1975 continues to apply to the edition of the BCA in force in Queensland, and that the Queensland Development Code continues to apply to the NCC edition in force.

NCC 2022 J1P1 caps hourly regulated energy for conditioned space at 80 kJ/m².hr for Class 6, 43 kJ/m².hr for Class 5, 7b, 8 and 9a (other than ward areas) and Class 9b schools, and 15 kJ/m².hr for other classes. There is no greenhouse gas cap in the NCC 2022 version.
For Class 3, 5, 6, 7, 8 and 9 buildings and Class 2 common areas, NCC 2022 J1V3 verifies compliance when the proposed building's annual greenhouse gas emissions are not more than the reference building's, with thermal comfort and Specification 33 requirements.
NCC 2022 J9D5 requires switchboard space for solar PV and battery systems, and at least 20% of the roof area left clear for PV panels, with exceptions in J9D5(2), such as where PV or equivalent on-site generation is already provided, the roof is heavily shaded or small, or most of it is used as a terrace or similar.
NCC 2022 J1P4 requires features that make it easier to add on-site renewable energy generation, storage and electric vehicle charging equipment later.
The ABCB's NCC 2022 Queensland appendix lists no Queensland variations to the Part J1 Performance Requirements or J1V3, so these national clauses apply as published.
Clause references are from NCC 2022 and NCC 2025 Volume One as published by the ABCB. For a national overview, see our NCC 2025 by state guide.
Design to NCC 2022 Section J. If the program could slip, we can show how the design performs against the NCC 2025 caps too, so a late application isn't a redesign.
Design to NCC 2025 from the start. The PV and J1P1 emissions caps affect roof layout, plant choice and gas use early, so we test them at concept stage.
We check the design against both editions and flag the items that change, such as the roof PV area, fuel type and glazing, so the team can decide with the facts.
We confirm the expected approval date and edition with you and your certifier.
We compare the Deemed-to-Satisfy and J1V3 pathways for your design.
We prepare the Section J report or J1V3 model, citing the NCC edition and clauses.
We answer certifier queries and update the report if the design changes, within the agreed scope.

On 1 May 2027. All NCC 2022 provisions remain in force in Queensland until 30 April 2027 (ABCB, NCC 2025 Queensland introduction).
Not under NCC 2022: the ABCB's Queensland appendix lists no Queensland variations to Section J. From 1 May 2027, Queensland's NCC 2025 variations remove the J6D10 and J8 requirements to reserve electrical capacity and space for future electric heating where gas is used. The Queensland Development Code continues to apply alongside the NCC edition in force.
Under NCC 2022 J1P1: 80 kJ/m².hr for Class 6, 43 kJ/m².hr for Class 5, 7b, 8 and 9a (other than ward areas) and Class 9b schools, and 15 kJ/m².hr for other classes.
From 1 May 2027, the NCC 2025 Deemed-to-Satisfy Provisions (J9D5) require an on-site PV system. Until then, NCC 2022 J9D5 requires switchboard space and at least 20% of the roof kept clear for PV, with exceptions listed in J9D5(2).
If your certifier confirms NCC 2025 will apply, plan for it now. The J1P1 emissions caps and J9D5 PV requirement can affect roof layout, plant and fuel choices, so test them early. We can check the design against both editions.
Yes. We model the proposed building against the reference building under the J1V3 edition that applies to your approval.
Yes. We're based in Melbourne and work on projects Australia-wide, using the NCC edition and state rules that apply in Queensland.
Timeframes are confirmed at quote, and fast-track is available for urgent projects.
We can test a design against NCC 2022 and NCC 2025, so a shifting program doesn't mean a redesign.
