The changes made to Part J1 2019’s deemed-to-satisfy requirements will have an impact on all projects throughout Australia. For example, in climate zones 1 and 2 (the generally warm and humid parts of Australia):

  • Insulation is now required to virtually all slabs on ground under 400 m².
  • Mostly glazed façades will typically be required to have double glazed windows with dark tinting.

The result of the above changes will likely lead to significant additional project costs and/or JV3 verification of the building fabric for each building.

There is now also a much stronger relationship between the building fabric and the building’s air conditioning. We therefore believe that it makes sense for the project’s mechanical consultant to also undertake the Part J1 assessment. Multitech has successfully undertaken both the mechanical design and Part J1 assessment for a number of recent projects.
