Documentation requirements

If the thermal loads meet the criteria described in the Modelling Process section, you will need to collect the following documentation:

  • the simulation output generated by Approved Software for the existing, reference, and proposed models;
  • a record of all assumptions made about the building fabric of the existing dwelling, signed by the applicant;
  • supporting evidence such as a letter from council, an engineer's report or a letter from the building or strata manager;
  • plans and specifications for the proposed work; and
  • photos of the existing dwelling.

The required simulation outputs from the existing and reference models are the interim/diagnosis reports and building data reports from the simulation software and/or the online system from the software provider.

The required simulation output from the proposed model is the NatHERS universal certificate issued from the online generation system by the software provider.
