What Does Section J Cover?
Section J of the NCC (Vol. 1) sets out mandatory energy efficiency standards for commercial buildings, to reduce operational energy demand, cut carbon emissions, increase occupant comfort, and ensure buildings meet performance thresholds required for permits or certifications.
J1- Energy Efficiency Requirements
Defines the overall energy efficiency standards that new buildings in Australia must meet under the NCC. It covers the required thermal performance of the building fabric, the efficiency of key energy-using systems, and provisions that support future integration of renewable and distributed energy resources.
J2- Energy Efficiency Performance Requirements
Explains how compliance is demonstrated through the NCC’s Deemed-to-Satisfy (DTS) Provisions in Parts J3 to J9. This section sets the benchmark for achieving cost-effective energy performance while aligning with Australia’s building sustainability objectives.
J3- Elemental Provisions for Class 2 and Class 4 Buildings
Outlines the Deemed-to-Satisfy (elemental) provisions for meeting the energy efficiency requirements in Part J1. It focuses on insulation standards and domestic service efficiency for sole-occupancy units within Class 2 (apartments) and Class 4 (mixed-use) buildings.
J4- Building Fabric (Roof, Walls, Floors & Glazing)
Details the energy efficiency requirements for the building envelope — including insulation, roof and ceiling performance, wall and floor systems, rooflights, and glazing. Compliance helps reduce heat loss, improve comfort, and lower building energy consumption.
J5- Building Sealing / Air Leakage
Specifies standards for sealing windows, doors, exhaust fans, and other openings to reduce unwanted air leakage. A well-sealed building improves occupant comfort, reduces heating and cooling loads, and supports overall energy efficiency compliance.
J6- Air-Conditioning & Ventilation Systems
Covers the efficiency and control requirements for HVAC, heating, and ventilation systems. It includes standards for ductwork insulation and sealing, efficient pumps and fans, and system controls to optimise building performance and reduce operational energy costs.
J7- Artificial Lighting & Power
Establishes energy efficiency limits for lighting and power systems, including design, zoning, and control requirements. Encourages the use of LED and sensor-based lighting, efficient lifts and escalators, and smart energy management for commercial buildings.
J8- Heated Water Systems & Pools/Spa Equipment
Sets out requirements for the efficient design and operation of water heating, pool, and spa systems. Promotes energy-saving technologies, adequate insulation, and optimised circulation systems for sustainable building performance.
J9- Energy Monitoring & On-site Renewable Energy Readiness
Specifies the need for energy monitoring systems and readiness for renewable energy or electric vehicle (EV) charging infrastructure. Enables better energy management and supports Australia’s transition to more sustainable and low-carbon buildings.

Why a Section J
Report is Essential
This report is vital for Performance improvement, compliance, energy efficiency, sustainability, occupant comfort, and informed design decisions throughout your project.
Permit & Certification Requirement
Councils and building surveyors require evidence of Section J compliance for building permits under NCC Volume 1. Without a valid report (or acceptable performance solution), permit approval may be refused.
Reduced Operating Costs
Better insulation, appropriate glazing, efficient air conditioning systems, and lighting reduce heating, cooling, and electricity costs over the life of the building.
Environmental & Sustainability Goals
Aligns your project with carbon emission and sustainability targets. Helps reduce energy demand and thereby helps with climate change goals or green building certification ambitions.
Occupant Comfort & Health
Proper thermal performance, ventilation, daylighting all contribute to better occupant comfort — fewer heat/cold spots, reduced reliance on artificial lighting and air conditioning.
Design Certainty Early On
Knowing what you must meet allows you to plan better: choose glazing, insulation, façade design, orientation etc. to meet NCC without costly rework
Improved Building Lifecycle Value
Supports design and material decisions that enhance the building’s durability, efficiency, and long-term operational savings.
Optional Performance Solution / Alternative (if needed)
If DTS is not feasible (e.g. glazing ratios too high, aesthetics or budget constraints), we explore verification or performance solutions (JV3, etc.) that allow trade-offs between building elements to achieve overall compliance when prescriptive compliance is difficult.
Our Simple, Transparent Section J Compliance Process
Submit Plans & Project Data
Provide architectural drawings (floor plans, elevations, section details), material specs (walls, roof, glazing), window schedule, climate zone, building class, and any design constraints. The more accurate the input, the more precise the report.
Preliminary Review & Quotation
We assess whether your design can comply via the DTS pathway or whether a performance-based method (e.g. JV3) is more viable. We quote the cost and turnaround and may provide sample reports.
Draft Report & Collaboration
We prepare a draft Section J report including minimum performance requirements, cross-section illustrate of fabric (walls, roof, floor), glazing mark-ups, services specifications. We work with your design/ESD/architect team to resolve any conflicts or changes.
Final Report Issued
After feedback & adjustments, you receive the final certified report ready for submission to certifiers/surveyors. All relevant drawings, specifications and performance tables included.
Step one takes five minutes of your time.
Send what you have. Floor plans and elevations are enough to start.
What Does a Section J Report Involve?
At SectionJReports.au we deliver comprehensive energy efficiency reports that do more than tick compliance boxes—they enhance clarity and coordination across your project team.
A Section J Report, as required under the National Construction Code (NCC 2022), evaluates the energy efficiency of a building’s fabric and services to ensure compliance with Australia’s building standards.
We take the time to
- Illustrate minimum insulation requirements across walls, roofs, floors, and glazing.
- Show window locations and thermal performance for accurate installation and compliance.
- Specify minimum efficiency standards for building services like HVAC, lighting, and hot-water systems.
This ensures your construction, design, and services teams are always on the same page.
Each report includes clear visual diagrams and cross-sections of building elements, specifying the minimum performance standards under the Building Code of Australia, helping builders install exactly what’s required, while allowing flexibility to achieve higher efficiency if desired.
We aim to help building owners minimise construction costs while maintaining excellent energy performance.
