Section J Assessment
NCC Section J energy efficiency assessments and JV3 modelling for commercial and mixed-use buildings.
Section J of the National Construction Code (Volume One) sets the energy efficiency requirements for commercial (Class 2-9) buildings. We provide both the Deemed-to-Satisfy (DtS) pathway and JV3 verification modelling to demonstrate compliance for the building fabric, glazing, services and lighting.
DtS and JV3 pathways
Where a building doesn’t fit neatly within the Deemed-to-Satisfy provisions, JV3 performance modelling compares your design against a reference building to prove an equal or better outcome - often unlocking more design freedom for glazing and facades.
What’s included
- Section J Deemed-to-Satisfy assessment
- JV3 performance-based verification where beneficial
- Fabric, glazing, services & lighting compliance
- Report suitable for certifier and council
Assessed under NCC 2022 Volume One, Section J, including JV3 verification using approved simulation methods.
The process
How it works
Send drawings
Provide architectural and, where available, services documentation.
We assess
We determine the most efficient compliance pathway for your design.
Report delivered
You receive a Section J compliance report.
FAQ
Section J Assessment - your questions answered
Residential Class 1 dwellings in NSW use BASIX. Commercial and many Class 2 apartment buildings require Section J (with BASIX still applying to the residential portions). We can advise which applies to your project.
JV3 is a performance-based verification method that models your actual design against a compliant reference building, often allowing more glazing or architectural flexibility than the Deemed-to-Satisfy path.
