Alterations & Additions

In Victoria all new Alterations and Additions to dwellings are required to meet  a minimum energy efficiency requirement as prescribed in the Performance Provisions of the National Construction Code, (NCC Volume 2).

This can be achieved in a number of ways, the most common being:

  • Thermal Performance Assessment, (commonly known as a 6 Star report).
  • Deemed-to-Satisfy report, (a prescriptive approach nominated in the NCC).
  • Performance Solution, (individually created to satisfy the Performance Provisions of the NCC).

We will advise which type of report is most appropriate for your project.

• Sections
• Window sizes or Window Schedule (including existing windows)
• Proposed heating/cooling type
