CPPHES5001 — Conduct thermal performance assessment of complex residential buildings

1 Prepare for thermal performance assessment.

• 1.1Consult with client to confirm scope and purpose of assessment and respond to questions to clarify issues and concerns.
• 1.2Check and apply relevant jurisdictional requirements to planned thermal performance assessment.
• 1.3Obtain documentation and drawings required for the assessment and check to verify consistency and sufficiency to meet software and regulatory requirements.
• 1.4Refer inconsistencies in documentation back to client for clarification and amendment.
• 1.5Analyse complex features of building envelope and construction methods and materials, and source technical advice to clarify requirements for thermal performance assessment.
• 1.6Source additional information required to conduct assessment to meet client and regulatory requirements.
• 1.7Check computer equipment to ensure correct operation and confirm software version and libraries are current and meet regulatory requirements.

2 Collate and input information into NatHERS software tool.

• 2.1Extract information required for input into software tool from building documentation and NatHERS technical notes.
• 2.2Enter extracted information into software tool according to regulatory requirements for all relevant building zones.
• 2.3Source and enter information about non-standard building materials and designs, alterations and additions correctly according to software and regulatory requirements.
• 2.4Check inputted data and make necessary adjustments to ensure accuracy and compliance with regulatory requirements.

3 Model thermal performance of building.

• 3.1Apply software tool functions and modelling methods suitable for building type and construction methods and materials.
• 3.2Run simulation to determine if the potential thermal performance of the building complies with regulatory requirements.
• 3.3Check simulation against latest documentation and amend identified discrepancies.
• 3.4Analyse software tool outputs to clarify assumptions, identify limitations and correct errors in data entry.
• 3.5Interpret software tool outputs and profile thermal performance strengths and weaknesses of building.

4 Identify options to improve thermal performance of building.

• 4.1Analyse profiled strengths and weaknesses in thermal performance of building.
• 4.2Access technical advice and identify cost effective options for improving thermal performance considering outputs of thermal performance assessment, client needs, practicality and building type.
• 4.3Identify interactions of suggested improvements on other aspects of building performance.
• 4.4Use software tool to reassess building and impact of identified options on thermal performance.

5 Evaluate options to achieve required energy rating.

• 5.1Conduct further analysis to identify changes to building design features to achieve required energy rating.
• 5.2Consult with client to present options, discuss viability of changes and seek direction for building reassessment.
• 5.3Apply software tool functions and modelling methods to generate thermal performance simulations based on recommended changes to design features.
• 5.4Negotiate with client to agree on the use of alternative materials or features to achieve required energy rating.

6 Report and certify thermal performance assessment outcomes.

• 6.1Finalise thermal performance assessment and collate design and assessment documentation in line with relevant jurisdictional regulatory requirements and for auditing and quality assurance.
• 6.2Document options and recommendations for achieving required energy efficiency rating according to regulatory requirements.
• 6.3Discuss assessment outcomes with relevant persons and obtain approval to proceed with certification according to organisational requirements.
• 6.4Submit NatHERS report through required portal to generate universal certificate.
• 6.5Confirm stamping is complete and secure documentation according to regulatory requirements.
• 6.6Store assessment documentation according to regulatory requirements and to enable recovery for audit and quality assurance purposes.

What does an assessment tool for CPPHES5001 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPPHES5001 needs to address all 47 unit components: 6 elements with 30 performance criteria, 6 performance evidence requirements, 9 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for CPPHES5001?

Auditori pulls the current release of CPPHES5001 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for CPPHES5001 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPPHES5001 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of CPPHES5001, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
