Section J Reports & Compliance
Section J is a national requirement under the National Construction Code (NCC), setting the energy efficiency standard for commercial, industrial, and multi-residential buildings across Australia. Ecomaxhomes prepares Section J reports for projects across New South Wales, demonstrating compliance with these NCC energy efficiency provisions. Whether your project suits the Deemed-to-Satisfy (DTS) pathway or requires JV3 performance-based modelling, we provide clear, council-ready documentation to support your Development Application and Construction Certificate.
What Is a Section J Report?
Section J of the NCC sets out the energy efficiency requirements for Class 2–9 buildings nationwide — covering the building fabric, glazing, air movement, air-conditioning, artificial lighting, and hot water systems. A Section J report demonstrates how your building design meets these requirements, either by following the prescriptive DTS provisions or by using performance-based JV3 modelling where the design departs from DTS requirements.
Our Section J Services
DTS (Deemed-to-Satisfy) Section J Assessment
For designs that align with the prescriptive requirements, we assess and document compliance against each relevant element — building fabric, glazing, services — without the need for full energy modelling.
JV3 Performance-Based Modelling
Where your design doesn’t meet DTS provisions, or where architectural flexibility is a priority, we run JV3 performance modelling to demonstrate equivalent or better energy performance against a DTS reference building.
Mixed-Use & Multi-Residential Buildings
For buildings combining residential (Class 2) and commercial (Class 5–9) components, we coordinate Section J assessment for the commercial portions alongside NatHERS/BASIX for the residential units.
Design-Stage Advice
We can review concept designs early and flag likely compliance issues — glazing ratios, insulation levels, HVAC efficiency — before they become costly changes later in the DA process.

Frequently Asked Questions
What’s the difference between DTS and JV3 for Section J?
DTS (Deemed-to-Satisfy) compliance follows prescriptive requirements for each building element. JV3 is a performance-based alternative that uses energy modelling to show your design achieves equivalent or better outcomes, giving more design flexibility where DTS provisions can’t be met.
Which buildings need a Section J report?
Section J applies nationally to Class 2–9 buildings under the NCC — this includes apartment buildings (common areas), offices, retail, industrial buildings, and other commercial and multi-residential developments. Ecomaxhomes prepares these reports for projects across NSW.
Can Section J and NatHERS/BASIX be assessed together?
Yes. For mixed-use buildings with both residential and commercial components, we coordinate Section J assessment for the commercial areas alongside NatHERS and BASIX for the residential dwellings, so your full development is covered.
How long does a Section J report take?
Turnaround depends on project complexity and whether DTS or JV3 modelling is required. Contact us with your building specs for an accurate timeframe.
Do you review designs before formal assessment?
Yes, we offer design-stage advice to flag potential compliance issues early, helping avoid costly redesigns later in the approval process.
