Elements and Performance Criteria
- Plan the NatHERS assessment.
- Need for assessing thermal performance of proposed residential building or part of building, including additions and alterations, is clarified with client.
- Effective communication strategies are used to assist in establishing rapport with the client and in responding to client questions and concerns.
- Potential risks are identified and suitably managed.
- Computer equipment and software required for the assessment are identified and checked for serviceability.
- Documentation required for the assessment is obtained.
- Drawings are checked for consistency, and adequacy and further information is sought as required.
- Limitations of data collected are identified.
- Authority to proceed is obtained from client prior to commencing, and is reconfirmed as appropriate during the assessment.
- Enter information into thermal performance assessment tool.
- Building information is obtained and entered into the thermal performance assessment tool.
- Methods for entering information on non-standard building materials and designs are implemented correctly.
- Methods for entering information required for assessing alterations and extensions are implemented correctly.
- Apply thermal performance assessment tool.
- Relevant functions of thermal performance assessment tool are used to generate outputs in relation to thermal performance of the building.
- Thermal performance assessment tool outputs are identified and analysed.
- Errors in data entry and assessment are identified and corrected.
- Limitations of software are identified and considered during assessment.
- Identify options for improving thermal performance.
- Sources of technical advice on building thermal performance are identified.
- Assumptions and limitations inherent in thermal performance assessment tool are considered when interpreting outputs.
- Thermal performance tool outputs are interpreted to identify strengths and weaknesses in thermal performance of building.
- Options for improving thermal and environmental performance and for meeting regulatory requirementsare identified based on criteria.
- Interactions of thermal performance improvements on other aspects of building performance are identified and advice is provided to client.
- Impact of options is evaluated by reassessing the building using the thermal performance assessment tool.
- Report outcomes of thermal performance assessment.
- Results and recommendations, along with supporting evidence, are collated and documented.
- Results and recommendations of thermal performance assessment are explained to the client.
- Reports and other documentation associated with thermal performance assessment are lodged with regulatory authorities if required, and securely stored to be readily retrieved in line with organisational requirements.
