Why Should You Consider JV3 Modelling And Assessment?
What Is A JV3 Assessment?
JV3 assessment defines an alternative assessment method for non-residential buildings. In
JV3 modelling, new buildings use a reference building to compare the overall energy
consumption pertaining to their location and climate.
A building having the exact same design, layout, and using similar building materials, can have
a different energy consumption than its twin located many kilometres away. Factors like its
location and specific weather conditions significantly affect the annual energy consumption.
Benefits of JV3 Modelling
1. Provides Cost-Effective Solution
The JV3 modelling, when used correctly, offers a cost-effective solution for the built
environment. Glazing and insulation are significant areas where costs reduction and enhancing
building performance can be implemented.
Insulation applications may be costly, especially under slab insulation in warm climatic regions.
Climatic zones 1, 2, 3 under the Australian Building Codes Board (ABCB) are warm regions.
In these warm zones, the energy performance of a building is extensively impacted by shaded
undercrofts and external shading than undercroft insulation.
The undercroft insulation can be typically deleted if you use JV3 modelling for an impact
assessment on the building and comparing it to the DtS provision's insulation performance. This
is one simple example of the JV3 modelling benefit.
2. Offers Greater Design Flexibility
With JV3 modelling, you enjoy design flexibility and ultimately reduce the overall cost. This
benefit is most useful for fire-rated areas of buildings.
Fire-rated materials generally have poor thermal insulating properties. Therefore, building a
double-wall is necessary. One wall is constructed to fulfil fire rating requirements, and another
one is attached to the first for meeting BCA section J compliance standards.
This entire exercise can be costly, and the thicker double walls may increase the overall
footprint of the building.
