Introduction: What Is NCC Section J Compliance?
If you are an architect, builder, building designer, or property developer working on a commercial project in Australia, understanding NCC Section J compliance is not optional — it is a legal obligation. NCC Section J compliance refers to meeting the energy efficiency requirements set out in Section J of the National Construction Code (NCC) 2022, administered by the Australian Building Codes Board (ABCB). These requirements govern the energy performance of new commercial buildings and major alterations across Classes 3 to 9. Understanding what is a Section J report, when it is required, what it includes, and how it differs from state to state is essential for every professional involved in commercial construction. This guide covers the key questions: Is section j mandatory in all states? What are the state-specific variations in NSW, Tasmania, the Northern Territory (NT), Victoria, Queensland, and South Australia? And what is the section j report cost you should budget for?
What Is Section J? The National Framework for Commercial Energy Efficiency
Section J is the energy efficiency chapter within Volume One of the NCC (formerly known as the Building Code of Australia or BCA). It applies to building Classes 3 and 5 through 9 — covering offices, hotels, retail shops, warehouses, hospitals, schools, restaurants, factories, and more. Class 2 apartment buildings have energy requirements for their common areas addressed under Section J, while their individual sole-occupancy units are assessed under specific sub-provisions.
The section j provisions were significantly strengthened in NCC 2022. According to the ABCB NCC 2022 webinar series on commercial energy efficiency, there are now two mandatory performance requirements, J1P1 and J1P2, with J1P2 being entirely new to NCC 2022. J1P1 governs energy use across all commercial building classes and the common areas of Class 2 buildings. J1P2 introduces a 7-star NatHERS equivalent thermal performance standard for Class 2 sole-occupancy units and Class 4 dwellings (with the exception of NSW, which uses BASIX). Additionally, J1P3 caps annual energy budgets for those same dwelling types, and J1P4 introduces mandatory on-site infrastructure for EV charging, solar panels, and battery readiness.
Is NCC Section J Compliance Mandatory in All Australian States?
Yes — NCC Section J compliance is mandatory for all new commercial buildings across every Australian state and territory. As confirmed by the Department of Climate Change, Energy, the Environment and Water (DCCEEW), state and territory governments give legal effect to the NCC through their own building legislation, making Section J a legally enforceable minimum standard. From 1 October 2023, section j of NCC 2022 Volume One applies nationally for Class 3 and Class 5 to 9 buildings.
However, while the baseline framework is national, there are important state-specific variations, transitional provisions, and additions that practitioners must understand. The NCC 2022 state and territory adoption dates published by the ABCB confirm that 1 May 2023 marked the primary adoption date, with full adoption of all energy efficiency provisions completed by 1 October 2023. Below, we examine the key differences state by state.
Key State Variations in NCC Section J Compliance
New South Wales (NSW): BASIX and Additional Performance Requirements
The section j report NSW context is uniquely shaped by the Building Sustainability Index (BASIX), administered by the NSW Department of Planning, Housing and Infrastructure. For Class 2 buildings (apartments) and Class 4 parts, NSW substitutes the NCC’s J1P2 and J1P3 provisions with BASIX requirements. This means thermal performance and annual energy budgets for individual units in NSW are regulated separately through BASIX rather than directly through section j of the NCC.
For Class 3 and 5–9 buildings, section j report NSW follows standard NCC 2022 Section J. However, NSW also introduces expanded jurisdiction-specific performance requirements, NSW J1P1 through NSW J1P7, as listed in the NCC Part J2 NSW variations. These additional clauses provide NSW-specific Deemed-to-Satisfy (DTS) pathways for commercial and residential-class buildings. NSW has stricter glazing solar admittance tables (NSW J4D6b and J4D6c) that apply to specific building classes, and the J1V5 verification pathway using a reference building does not apply in NSW — only in all other states and territories.
Tasmania: Retained BCA 2019 for Certain Residential Classes
Tasmania presents the most distinct variation to standard NCC Section J compliance rules. According to the NCC Part J1 energy efficiency performance requirements, for Class 2 buildings and Class 4 parts of buildings in Tasmania, Section J is replaced entirely by Section J of the BCA 2019 Amendment 1. This is a specific jurisdictional retention of older requirements for those residential-type building classes and represents a notable departure from the national standard. Tasmania’s building regulation is governed by the Consumer, Building and Occupational Services (CBOS). For Class 3 and Class 5–9 commercial buildings, Tasmania follows the NCC 2022 framework with no further known variations beyond this class-specific retention.
Northern Territory (NT): Full NCC 2022 Adoption
The Northern Territory adopted NCC 2022, including the updated section j energy efficiency provisions, in line with the national timetable. NT building regulation is administered by the NT Building Advisory Services. The Territory applies NCC 2022 Section J without the jurisdiction-specific class replacements seen in Tasmania or the BASIX overlay seen in NSW. All Class 3 and 5–9 buildings in the NT require a section j compliance report in accordance with NCC 2022. Given the NT’s unique placement across multiple climate zones — particularly the high humidity and extreme heat of Climate Zone 1 — Section J requirements for glazing solar admittance, roof reflectance, and HVAC efficiency are especially demanding. Early engagement with an energy assessor is strongly advised.
Victoria (VIC): Standard NCC 2022 with Climate Zone Considerations
Victoria adopted NCC 2022 in accordance with the national timeline under the Victoria Building Authority (VBA). Victoria’s Schedule 10 within the NCC sets out any jurisdiction-specific variations. For section j, Victoria does not introduce significant departures from the base NCC 2022 framework for commercial buildings. Buildings in Melbourne (Climate Zone 6) face stricter insulation requirements than their Queensland counterparts, reflecting the cooler temperate climate. Alpine areas in Victoria (Climate Zone 7) require higher Total R-Values for roofs and walls. Practitioners preparing section j compliance report documentation for Victorian projects must ensure climate zone accuracy to avoid underspecifying insulation and glazing performance.
Queensland (QLD): Adoption Under the Building Act 1975
Queensland implemented NCC 2022 under the Queensland Building and Construction Commission (QBCC) framework and the Building Act 1975. Section j applies in full for commercial building classes from 1 October 2023. Queensland spans Climate Zones 1 through 5, with most of the coastal population in Climate Zones 2 and 3. This means commercial buildings in Brisbane and south-east Queensland must carefully manage solar heat gain through glazing and building sealing, while far-north Queensland projects in Climate Zone 1 face even more stringent solar admittance limits and roof reflectance requirements. There are no Queensland-specific replacement provisions for Section J class requirements equivalent to those in NSW or Tasmania.
South Australia (SA): Standard Adoption, High Climate Zone Diversity
South Australia operates under the SA Planning and Development Online framework and adopted NCC 2022 in line with the national schedule. South Australia covers Climate Zones 3 and 5, with Adelaide in Climate Zone 5 (warm temperate) and the state’s north in Climate Zone 3 (hot dry summer). For commercial developments, the section j compliance report requirements in SA follow the base NCC 2022 without significant jurisdiction-specific variations. Assessors working on section j in SA must ensure roof Total R-Values, glazing performance, and HVAC system efficiencies are appropriate for the applicable climate zone, as minimum standards vary considerably between Climate Zones 3 and 5.
What Is a Section J Report? Key Components Explained
So, what is a section j report? A section j compliance report is a formal document prepared by a qualified energy efficiency consultant or energy assessor that demonstrates a proposed commercial building design meets the energy efficiency requirements of Section J of the NCC. It is required at both the Development Application (DA) and Construction Certificate (CC) stages and must be lodged with the relevant consent authority or certifier.
Understanding what is a section j report in practical terms means knowing what it must contain. A comprehensive section j compliance report typically addresses the following nine technical domains under NCC 2022:
- Building Fabric (Part J4): Minimum Total R-Values for roofs, walls, and floors; thermal bridging calculations for steel studs and shelf angles; and facade assessment combining wall and glazing performance.
- Glazing (Part J4): Maximum Total System U-values and Solar Heat Gain Coefficients (SHGC) for windows; facade calculator outputs for wall-glazing constructions.
- Building Sealing (Part J5): Requirements for airlocks at building entrances; sealing of openable windows and doors to limit uncontrolled air infiltration.
- Air-Conditioning and Ventilation (Part J6): Minimum COP and EER values for HVAC plant; ductwork insulation; economy cycle controls; demand-controlled ventilation.
- Artificial Lighting and Power (Part J7): Maximum Lighting Power Density (LPD) limits by space type; automatic lighting control requirements.
- Heated Water Supply (Part J8): Minimum requirements for hot water system efficiency and swimming pool heating.
- Energy Monitoring (Part J9): Sub-metering requirements for buildings over 500 m²; smart metering for buildings over 2,500 m².
- On-Site Distributed Energy (Part J9): EV charging infrastructure readiness; switchboard provision for future solar PV and battery systems; solar panel area reservation for roofs over 55 m².
- Condensation Management (Part J3): Interstitial condensation mitigation requirements for building envelopes in cooler climate zones.
Two Pathways to Section J Compliance: DTS vs JV3
There are two primary pathways to achieving NCC Section J compliance, as detailed in the NCC 2022 Section J provisions:
- Deemed-to-Satisfy (DTS): A prescriptive compliance pathway where each building element and system must individually meet the minimum standards tabulated in Parts J2–J9. It is straightforward to assess and generally faster to produce.
- JV3 Performance Solution: An energy modelling approach using validated software (compliant with ANSI/ASHRAE Standard 140, such as EnergyPlus) that demonstrates the proposed building’s total annual greenhouse gas emissions do not exceed those of a reference DTS-compliant building. JV3 allows significant design flexibility — particularly useful for buildings with high window-to-wall ratios where the DTS glazing limits would be overly restrictive.
Additional pathways include J1V1 (NABERS Energy pathway for Class 5 offices, Class 3 hotels, Class 2 common areas, and large Class 6 shopping centres) and J1V2 (Green Star pathway). For Class 2 sole-occupancy units in all states except NSW, the J1V5 reference building verification method is also available. You can explore more compliance pathways on our Commercial Energy Efficiency Assessments page, and review the ABCB’s guidance on NCC 2022 Performance Solutions.
Section J Report Cost: What Should You Budget?
One of the most common questions from architects, builders, and volume builders is: what is the section j report cost? The section j report cost depends on several variables including building size, classification, complexity, chosen compliance pathway, and the assessor’s experience.
Industry benchmarks for section j report cost in Australia currently range as follows:
- Small simple DTS report: From approximately $500–$1,200 (e.g. a single-storey café, small retail tenancy, or simple warehouse).
- Mid-complexity commercial building: $1,200–$4,000 (e.g. multi-tenancy office building, hotel, school).
- Large or complex building or JV3 modelling: $4,000 to several thousand dollars, depending on scope and iterations required.
Engaging an energy assessor early in the design phase is the most cost-effective approach. Late-stage design changes — particularly to glazing specifications or HVAC systems — triggered by a non-compliant section j report can cost far more than the assessment fee itself. For a related discussion on ESD reporting requirements, see our internal guide on Sustainable Design Assessments for Development Applications. You can also review typical section j report cost ranges directly with qualified assessors listed through the Australian Institute of Building Surveyors (AIBS).
Conclusion
NCC Section J compliance is a non-negotiable obligation for all new commercial construction in Australia. Whether you are developing a Class 5 office in Sydney, a Class 3 hotel in Darwin, or a Class 9b school in Melbourne, a section j compliance report prepared by a qualified energy assessor is required before your Construction Certificate can be issued. Understanding what is a section j report, the applicable state variations, the section j report cost range, and when it is required will help architects, builders, volume builders, designers, planners, and surveyors avoid costly delays. Integrate section j assessment into your design workflow from concept stage, select the right compliance pathway for your project, and engage an experienced assessor familiar with your jurisdiction’s specific requirements.

FAQs
An ESD (Ecologically Sustainable Development) assessment is a technical report prepared alongside a development application that shows how a project has been designed to reduce its environmental footprint across energy, water, materials, waste, transport, and climate resilience. In NSW, the NSW Planning Portal frames ESD as a core assessment principle for State significant projects, while day-to-day residential and commercial development is guided by the Sustainable Buildings SEPP. Depending on the scale of the project, the ESD assessment may take the form of a short sustainability statement, a full ESD report addressing Secretary’s Environmental Assessment Requirements (SEARs), or a BASIX certificate for a single dwelling.
ESD compliance means a development satisfies the mandatory sustainability standards that apply to it under the relevant State Environmental Planning Policy, Local Environmental Plan (LEP), and Development Control Plan (DCP). For residential development, this is measured through a BASIX certificate, which since 1 October 2023 has aligned thermal performance and energy standards with the National Construction Code. Importantly, the Sustainable Buildings SEPP FAQ published by the NSW Department of Planning confirms that councils cannot set residential sustainability standards higher than those in the SEPP, though for non-residential development the SEPP sets only a minimum standard, and councils such as the City of Sydney may apply additional local requirements. A compliant ESD report will reference the specific SEPP clauses, DCP controls, and any SEARs that the assessing authority has issued for the site.
Cost varies significantly with project scale and complexity, and no Australian government body publishes a fixed fee schedule for private ESD consulting — pricing is set by the market. As a general guide from industry practice:
- Single dwellings / BASIX certificates: typically the most affordable option, often bundled with a Nationwide House Energy Rating Scheme (NatHERS) assessment.
- Multi-dwelling housing, duplexes, townhouses: a moderate fee reflecting BASIX-for-multi-dwelling requirements plus a written sustainability statement.
- Larger commercial, mixed-use or State Significant Development: a higher fee to address full SEARs-based ESD reporting, NABERS commitments, climate risk assessment, and a Sustainability Management Plan.
Because fees depend on project type, always request an itemised quote referencing the specific SEPP, DCP and SEARs obligations that apply to your site — a reputable ESD consultant will confirm applicability using the NSW Planning Portal before quoting.
Yes. Addressing ESD requirements early — at concept design stage rather than after documentation is complete — allows the design team to select cost-effective compliance pathways instead of expensive retrofits later. The NSW Department of Planning notes that homes meeting the current BASIX energy and thermal performance standards are expected to save over $1,000 per year in energy bills compared with pre-October 2023 standards, which flows through to lower operating costs for owners and tenants. Early ESD input can also avoid costly design changes triggered by a council request for further information, and can identify low-cost passive design measures (orientation, glazing, insulation) that reduce reliance on mechanical heating, cooling and larger renewable energy systems.
An ESD report itself does not carry a statutory expiry date in the way a BASIX certificate does, but it must reflect the version of the plans lodged with the DA and the version of the relevant SEPP in force at that time. A BASIX certificate must remain consistent with the approved plans through to construction certificate and post-consent completion, and if the design changes, or if the Sustainable Buildings SEPP standards are updated, the certificate or ESD report generally needs to be revised and re-submitted. Consent authorities will typically ask for an updated ESD report if there is a material change to the approved development or if construction has not commenced within the validity period set by the relevant consent.
These three terms are often used together but describe different stages and scopes of sustainability documentation:
- ESD Report / ESD Statement — prepared at DA stage to demonstrate how the proposed design responds to ecologically sustainable development principles and satisfies applicable SEPP, LEP, DCP and SEARs requirements.
- SDA (Sustainable Design Assessment) — a more detailed technical assessment, often required by inner-city councils for larger or more complex developments, that tests specific sustainability initiatives (e.g. energy modelling, NABERS ratings, water reuse) in greater depth than a general ESD statement.
- SMP (Sustainability Management Plan) — an operational document, generally required as a condition of consent, that sets out how the sustainability commitments made in the ESD/SDA report will actually be implemented, monitored and reported on during construction and ongoing operation of the building.
Exact terminology and thresholds vary between councils, so always confirm which document a Development Control Plan requires by checking your council’s DCP alongside the NSW Planning Portal guidance for your project type.
ESD is not a stand-alone add-on to a DA — it is embedded in the statutory planning framework. State Environmental Planning Policies made under the Environmental Planning and Assessment Act 1979 (NSW), such as the Sustainable Buildings SEPP, sit above council LEPs and DCPs and set the minimum sustainability outcomes a consent authority must consider. For State Significant Development and Critical State Significant Infrastructure, the Department issues project-specific Secretary’s Environmental Assessment Requirements (SEARs) that explicitly list the ESD principles to be addressed. A Statement of Environmental Effects or Environmental Impact Statement that does not demonstrate compliance with the applicable SEPP cannot be assessed as complete, so an ESD report should be prepared alongside — not after — the architectural and town planning documentation, and cross-referenced against your council’s DCP and any relevant strategy such as the NSW Net Zero Plan.
