When is a JV3 Assessment required?

JV3 can be used as an alternative solution when a section J report is required. This applies when a building's complex design does not meet the Deemed to Satisfy (DtS) requirements under the National Construction Code (NCC).  JV3 allows much more flexibility with regards to design choices, as architects and designers can create as they see fit as long as it does not exceed the reference buildings energy usage targets. JV3 is much like a non-residential equivalent of NatHERS modelling, allowing flexibility to choose glazing and building elements as long as it stays within the annual energy consumption of the Deemed-to-Satisfy (DtS) building.

The JV3 Assessment requires a detailed assessment of the building's design. The feedback that is given from the JV3 model should be a consideration in the detailed design's development.

DtS Solutions

A DtS Solution requires at least one of the Assessment Methods under the NCC to be used. These include an Evidence of Suitability and Expert Judgement.

Example of the JV3 Verification Assessment Method

Below is a step-by-step outline of conducting an analysis to determine whether the Performance Solution satisfies the Performance Requirement.

Step 1 - DtS provisions are used to establish the base performance
