What is JV3 modelling?

JV3 is a performance-based modelling method used to show compliance with Section J of the National Construction Code. It allows more flexibility by comparing your proposed building design to a benchmark building that meets the minimum Deemed-to-Satisfy provisions.

Short answer

JV3 modelling uses computer simulation to prove that your design performs as well as or better than a compliant reference building under the NCC.

Full answer

JV3, also known as the Verification Using a Reference Building method, is part of the performance solution pathway under the NCC. It compares annual energy loads of your proposed building with a reference building that meets minimum standards.

This allows for creative or complex designs that may not fit standard Deemed-to-Satisfy criteria. JV3 is commonly used for buildings with large glass areas, unusual shapes, or mixed-use spaces.

Why this matters

JV3 can unlock design flexibility and cost savings while still meeting energy performance standards. It is often the only way to achieve compliance for unconventional buildings.

How Certified Energy can help

We carry out the full JV3 simulation using accredited software. Our team works with your architect or engineer to model your design and optimise it for compliance without unnecessary trade-offs.
