JV3 is an alternate assessment method when a section J report is required. With the JV3 assessment, non-residential developments use a reference building for comparing the total estimated energy consumption of the new building.
Specific non-residential projects featuring complex designs, e.g. large external glazing areas, may struggle to achieve compliance using the Deemed to Satisfy (DTS) provisions of BCA Volume 1, Section J (Energy Efficiency) without mentioning insulation or glazing that is extravagantly expensive.
Additionally, in certain cases, the complexity or the intricate features of a building’s design, combined with the NCC Climate Zone, makes it completely impossible to adhere to the compliance requirements under DTS provisions.
Thanks to the JV3 assessment. It is still possible for the new developments that are unable to comply with DTS provisions to achieve compliance using the JV3 verification method.
JV3 modelling is applicable for all the buildings belonging to Class 3, 5, 6, 7, 8, and 9 and excludes buildings under Class 2 and 4.
Why JV3 Modelling And Assessment Is Beneficial?
With the power and versatility of JV3 assessment, this process is now receiving incredible recognition.
Simple developments such as single-storey office buildings do not face any challenges from using the DtS provisions. However, most buildings except the type mentioned previously should utilize the benefits of the JV3 modelling.
Here are some benefits of using the JV3 method of verification and modelling.
Elimination Or Reduction Of Unnecessary Insulation, Including Roof And Ceiling Insulation.
Different climatic conditions have different insulation requirements. Adjusting insulation based on climatic conditions reduces costs and enhances building performance.
Alternative Solution For Internal Wall Insulation For Fire-rated Buildings
Under DTS compliance, fire-rated buildings require double walls. One to adhere to the fire rating standards and another lining attached to the first to comply with the BCA section J specifications. In certain cases and climatic zones, double walls are not expensive but can increase the overall carbon footprint. JV3 modelling offers an alternative solution to this.

Provides Direct Assessment Of A Building’s Positive And Negative Aspects
Unlike DTS protocols, the JV3 modelling does not limit the building materials used. It does not mandate an overall increase in the thickness of walls.
Balanced building performance can be achieved that reduces insulation in certain areas of the building while increasing the performance in specific parts of the building where the materials will surely have a greater impact. This not just reduces construction expenditure but also future operational costs.
Conclusion
The JV3 assessment has enabled and empowered engineering and building professionals to offer the industry a clear pathway to devise performance solutions and direct verification methods that allow a robust and flexible compliance assessment to achieve the performance requirements of the BCA Section J.
