Learning Outcomes and Application This unit of competency specifies the outcomes required to assess the impact of construction materials, design elements and building condition on thermal performance of residential buildings. It includes selecting appropriate building materials for improving thermal performance, identifying the impact of the construction of key elements of the building envelope on thermal performance, and identifying the correct use and installation of building materials to improve thermal performance.The unit supports the work of Nationwide House Energy Rating Scheme (NatHERS) assessors engaged in assessing the impact of building elements.In some jurisdictions, this unit of competency may form part of the accreditation, licensing, legislative, regulatory or certification requirements for NatHERS assessors.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

The following must be present and available to learners during assessment activities:

equipment:

computer equipment suitable for accessing online catalogues and references to source information on the thermal performance of construction materials

relevant codes, standards and government regulations

technical reference library with current publications on:

passive building design

thermal performance of building materials and construction methods

building thermal performance

house energy rating schemes (HERS)

common building features that impact on thermal performance

relationships with team members and supervisor:

assessment activities are performed on an individual basis under general supervision.

Assessor requirements

As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.
