JV3 Verification Solution

JV3 Assessments simplify compliance with Section J of the BCA. For buildings not complying with the DTS provisions of a BCA Section J report, the alternative method of compliance is via a JV3 Alternative Solution, or Verification Using a Reference Building. This alternative verification method compares a DTS compliant “reference” building, against the design “proposed” building. The two buildings are modelled and simulated in computer software to determine the total energy consumption over a full year. When the “proposed” building outperforms the “reference” building (i.e uses less energy), it is deemed to meet compliance. Therefore in general JV3 assessments are the most cost-effective option for compliance with Section J.

JV3 Advantages:

Straight Section J assessments work well for simple buildings with minimal glazing. For most commercial projects however, JV3 is now considered the standard method of assessment to achieve cost effective compliance. There are many benefits to JV3 assessments derived from the ability to consider the building as a whole, instead of individual components in isolation. This provides much greater design flexibility and the ability to trade performance between different building elements. This in turn result in building specifications that can provide huge savings in construction costs and ongoing running costs.
