Unit Descriptor

This unit of competency specifies the outcomes required to collect information on the costs of measures required to improve the thermal performance of planned and existing residential buildings which may be identified through a Nationwide House Energy Rating Scheme (NatHERS) assessment. It includes confirming required measures for improving thermal performance, gathering information on costs of measures, and analysing those costs.

Application of the Unit

This unit of competency supports the work of NatHERS assessors engaged in assessing, and making recommendations for improving, the thermal performance of planned and existing residential buildings.

Licensing/Regulatory Information

In some jurisdictions, this unit of competency may form part of the accreditation, licensing, legislative, regulatory or certification requirements for NatHERS assessors.

Pre-Requisites

Not applicable.

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

1	Confirm potential measures for improving thermal performance.	1.1	Measures for improving thermal performance of residential buildings are identified in line with organisational procedures.
1.2	Details of potential measures for enhancing thermal performance of building are identified and confirmed with client.

2	Gather information on cost of measures to improve thermal performance.	2.1	Information on cost of measures to improve thermal performance is researched and obtained from appropriate sources.
2.2	Information on rebates and other forms of assistance for particular measures to improve thermal performance is researched and obtained.
2.3	Information on availability, suitability and likely supply time of products and services, where applicable, is obtained in line with organisational procedures.
2.4	Factors that may influence cost of measures are identified and documented.
2.5	Information on cost of measures is collated and documented.
2.6	Ethical practices are observed in identifying and gathering product and service information.
2.7	Details of information obtained on products and services are maintained and securely stored.

3	Analyse cost of measures to improve thermal performance.	3.1	Information on costs of measures to improve thermal performance of building is collated and analysed in line with organisational policy and procedures.
3.2	Indicative costs of measures to improve thermal performance are determined in line with organisational procedures.
3.3	Limitations of cost information are identified in line with organisational policy and procedures.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment	This unit of competency could be assessed by candidates collecting and analysing information on the costs of measures for improving the thermal performance of a residential building based on the outcomes of a NatHERS assessment of potential options.
Critical aspects for assessment and evidence required to demonstrate competency in this unit	A person should demonstrate the ability to: identify potential measures for improving the thermal performance of residential buildings gather information on costs of measures for improving thermal performance of residential buildings analyse costs of measures for improving thermal performance of residential buildings identify limitations of cost information.
Context of and specific resources for assessment	Assessment of this unit: must be in the context of the work environment may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills must meet relevant compliance requirements. Resource implications for assessment include: computer equipment suitable for producing reports for clients technical reference library with current publications on energy efficiency materials, products and services.
Method of assessment	Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods: written and/or oral assessment observed, documented and/or first-hand testimonial evidence of the candidate collecting and analysing information on the costs of measures for improving the thermal performance of a residential building based on the outcomes of a NatHERS assessment of potential options.
Guidance information for assessment	This unit could be assessed on its own or in combination with other units relevant to the job function. Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
