This formal CPD course is designed for professionals involved in energy efficiency and compliance assessments of multi-residential buildings in Australia, particularly those classified as Class 2 under the NCC 2022. It is ideal for NatHERS energy assessors, sustainability consultants, and architects who need to model thermal performance, fixed appliances, and shared systems accurately. The course addresses the complexities of shared walls, zoning overlaps, and central hot water systems, offering practical guidance on using proxies and documentation for compliance. Its goal is to equip participants with the knowledge and tools to deliver accurate, defensible assessments that meet NCC and NatHERS requirements.

Building Surveyors
Sustainability Consultants

By the end of this session, you will be able to identify and address the unique challenges involved in modelling Class 2 apartments under the NatHERS and NCC 2022 frameworks. You’ll understand how to accurately represent shared construction elements, complex zoning, and fixed appliance systems in multi-residential buildings. The session will also teach you when and how to apply the central hot water system proxy, and when its use is inappropriate. Additionally, you’ll gain the skills to prepare thorough compliance documentation, including evidence of suitability and proxy justifications. This will ensure your assessments are both accurate and fully compliant with regulatory standards.

  • Explain the specific thermal and compliance challenges associated with Class 2 buildings under NCC 2022 and NatHERS.
  • Identify when performance solutions are required and prepare appropriate supporting documentation.
  • Accurately model thermal shells in NatHERS software, accounting for shared walls, zoning, and exposure.
  • Incorporate and model fixed appliances—such as heating, cooling, water heating, and lighting—for Whole-of-Home assessments.
  • Apply the central hot water system proxy correctly, based on Clause 12.10 of the NatHERS Technical Note.
  • Prepare audit-ready compliance reports that include modelling assumptions, justification of proxies, and evidence of suitability.

This ensures that CPD efforts align with professional regulatory requirements.

What’s Included

This course covers the key principles and practical steps for accurately modelling Class 2 multi-residential buildings under NatHERS and NCC 2022. It addresses the unique thermal performance challenges of shared walls, repeated layouts, and zoning in apartment settings. The course explains how to use the central hot water system proxy, including when it is appropriate and how to document its use. It also provides guidance on modelling fixed appliances and preparing complete, compliant documentation for regulatory approval.

  • A 1-hour video session covering NCC-aligned strategies and real-world case studies.
  • An interactive quiz to test and reinforce knowledge.
  • An audio summary version via NotebookLM for flexible, on-the-go learning.
  • A downloadable certificate of completion for CPD compliance reporting.
  • Centralised CPD tracking dashboard to support audits and personal recordkeeping.
