If you are involved in Commercial or Industrial building design, construction, or operation, then you’re probably familiar with Section J reports, which can be done prior to securing a construction certificate.
The requirements can seem complex, and the process can look tedious. There could even be some legal risks, like liability for building defects or non-compliance.
How can you hurdle those challenges?
Section J: What It Is and Why It’s Needed
New buildings often need a Section J report to go with their development application and/or a construction certification. Section J is that part of the National Construction Code (NCC) that sets the minimum energy efficiency standards for Class 2 to 9 buildings in Australia. Its underlying purposes are to reduce greenhouse gas emissions and improve building comfort and performance.
Preparing a Section J Report
A qualified assessor should be able to help you draft a Section J report and the checklists below can be greatly useful in the process.
Documents Checklist
You must first gather the necessary documents as you will need the primary information they contain.
- Architectural Plans & Specifications – detailing the building’s design, layout, materials, and construction methods
- Building Fabric Details – with information about walls, roofs, floors, insulation types, R-values, U-Values (your assessor can assist with the building fabric values)
- Lighting Design & Fixtures – lighting design, fixture types, wattage, placement, etc. (your assessor will specify the maximum lighting wattage allowance as part of the assessment)
- HVAC System Specifications – heating, ventilation, and air conditioning systems, including efficiency, sizing, zoning, and controls
- Glazing Information – specifications for windows and glazing, with U-values and Solar Heat Gain Coefficient (SHGC)
- Energy Monitoring Facilities – plans for tracking and optimising energy usage
- Compliance Reports – covering all aspects of energy efficiency
- Occupation Certificate (OC) Application – including evidence of Section J compliance
Project Scope & Intended Use Checklist
Next, clarify the project’s scope and all related information:
- Project Scope
- Overall scope, including purpose, scale, and complexity
- Must align with the project’s vision, mission, and goals
- Specific building areas covered by the assessment (e.g., retail spaces, offices, common areas)
- Any alterations or additions that are part of the project
- Must be communicated to and agreed upon by all stakeholders. Ensure everyone agrees with it before proceeding with the pre-assessment.
- Intended Use
- Clarify if it is a retail space, an office building, or a mixed-use development.
- Consider how different areas within the building will be utilised (e.g., retail shops, cafes, storage).
- Understand the occupancy patterns and energy requirements based on the building’s function.
- Building Information
- Classification
- Location / Climate Zone
- Orientation
- Floor area
- Glazing area
- Envelope area
- Section J Provisions: Which specific provisions of Section J applies to your project?
- Part J1 Energy efficiency performance requirements
- Part J2 Energy efficiency
- Part J3 Elemental provisions for a sole-occupancy unit of a Class 2 building or a Class 4 part of a building
- Part J4 Building fabric
- Part J5 Building sealing
- Part J6 Air-conditioning and ventilation
- Part J7 Artificial lighting and power
- Part J8 Heated water supply and swimming pool and spa pool plant
- Part J9 Energy monitoring and on-site distributed energy resources
BCA Section J Checklist
When preparing a Section J under the Building Code of Australia (BCA), you need to include a detailed description of how each applicable part is complied with and a list of the evidence of suitability for each material, product or system used to achieve compliance (e.g., certificates, test reports or manufacturer’s specifications). You will also need to state that the report has been prepared by a qualified Section J consultant and that the information provided is true and accurate.
- Part J1 Energy efficiency performance requirements
- Check applicable performance requirements for the development. Determine which Verification Method is to be adopted if chosen as a pathway to compliance.
- Recommend improvements or alternatives if needed (also applies to all parts below).
- Part J2 Energy efficiency
- Check applicable Deemed-to-Satisfy Provisions relative to the development. Check orientation, shading, insulation, glazing, lighting, and services.
- Recommend measures to reduce heat gain or loss, improve natural ventilation and daylighting, and optimise the use of energy-efficient equipment and systems.
- Part J3 Elemental provisions for a sole-occupancy unit of a Class 2 building or a Class 4 part of a building
- Check the construction and insulation of walls, floors, ceilings, and roofs that separate the unit from unconditioned parts of the building or the external environment.
- Check the sealing of windows, doors, vents, ducts, and other openings that affect the air leakage of the unit.
- Check the installation and operation of air-conditioning and ventilation systems, artificial lighting and power outlets, heated water supply, and appliances that consume energy in the unit.
- Part J4 Building fabric
- Check the construction and insulation of walls, floors, ceilings, and roofs that form part of the building envelope.
- Check the thermal performance of glazing elements, including windows, skylights, glass doors and curtain walls.
- Check the shading devices (e.g., awnings, louvres, screens, blinds) that reduce solar heat gain through glazing elements.
- Part J5 Building sealing
- Check the sealing of windows, doors, vents, ducts, and other openings that affect the air leakage of the building or its zones.
- Check the ventilation requirements for conditioned spaces, unconditioned spaces, roof spaces, and subfloor spaces.
- Check the air infiltration rates and air change rates for different types of spaces and occupancies.
- Part J6 Air-conditioning and ventilation
- Check the design, installation, and operation of air-conditioning and ventilation systems, including ductwork, fans, filters, dampers, controls, and sensors.
- Check the energy efficiency and performance of air-conditioning and ventilation equipment (e.g., chillers, boilers, pumps, heat recovery units, variable speed drives, and renewable energy sources).
- Check the compliance with the relevant standards and codes for air-conditioning and ventilation systems.
- Part J7 Artificial lighting and power
- Check the design, installation, and operation of artificial lighting systems, including lamps, luminaires, ballasts, drivers, controls, and sensors.
- Check the energy efficiency and performance of artificial lighting systems in relation to illumination levels, lighting quality, visual comfort, and glare control.
- Check the compliance with the relevant standards and codes for artificial lighting systems.
- Part J8 Heated water supply, swimming pool, and spa pool plant
- Check the design, installation, and operation of heated water supply systems, including water heaters, pumps, pipes, valves, controls, and sensors.
- Check the energy efficiency, performance, and safety of heated water supply systems in relation to water temperature, pressure, flow rate, and quality.

End Goal: Energy-Efficient Buildings
A BCA Section J assessment should be one of the top priorities in building design and construction and be considered early in the design and development application process. After all, building greener structures benefits the building owner, users, and their communities as well.
