By the end of this session, you will understand the full scope of Whole-of-Home (WoH) compliance, including how thermal performance, fixed appliances, and renewable systems contribute to a building’s energy profile under NCC 2022. You’ll learn how to model each component accurately using NatHERS-accredited software, apply defaults appropriately, and document all assumptions to meet audit and certification requirements. You will also be able to identify when re-rating is necessary due to design changes and how to manage compliance documentation with transparency and consistency.

Learning Outcomes

  • Understand the scope of Whole-of-Home compliance, including the integration of thermal shell and service loads in energy assessments.
  • Identify key re-rating triggers and follow proper workflows to update models and documentation when design changes occur.
  • Accurately model fixed appliances, hot water systems, and HVAC units using approved efficiency factors and NatHERS-accredited software.
  • Generate audit-ready compliance documentation, including NatHERS Certificates and Whole-of-Home Summaries, aligned with NCC Part A5.
  • Apply and justify the use of default values when system specifications are unknown, ensuring compliance with regulatory standards.
  • Collaborate effectively with designers, certifiers, and clients to ensure accurate assumptions, consistent inputs, and timely compliance outcomes.

This ensures that CPD efforts align with professional regulatory requirements.

This CPD provides general guidance on professional responsibilities and documentation practices. It does not constitute legal advice or replace project-specific contractual or statutory obligations.

What’s Included

This course covers the full process of conducting Whole-of-Home (WoH) energy assessments in line with NCC 2022 and NatHERS requirements. It teaches how to model thermal performance, fixed appliances, PV systems, batteries, and plug loads using accredited software and standard efficiency factors. Participants learn when to apply defaults, how to justify assumptions, and how to manage re-ratings due to design changes. The course also explains how to produce audit-ready compliance documentation aligned with NCC Part A5.

  • 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.
