Elements and Performance Criteria

  1. Plan and organise review of thermal performance of existing residential building.
  2. Gather and analyse information on thermal performance of existing residence.
  3. Assess options for improving thermal performance of existing residence.
  4. Report outcomes of thermal performance review of existing residence.

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Need for review must include at least one of the following:

building design or retrofit advice purposes

determining thermal performance profile and identifying opportunities for improving thermal performance

legislative, regulatory and compliance purposes.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also review the thermal performance of three different existing residences using non-rating tools and techniques. The buildings must be drawn from the following classes of buildings under the National Construction Code (NCC): Class 1 buildings, sole occupancy units (SOU) in Class 2 buildings, or Class 4 buildings.

In doing the above, the person must:

gather the building information required to conduct a thermal performance review of the existing residence

identify options for improving the thermal performance of the existing residence, taking into account the type of building, ownership of building, cost and practicality

apply knowledge of:

Australian climatic zones

building thermal performance principles

non-rating tools and techniques

passive energy design principles

relationship between building thermal performance and thermal comfort

thermal performance properties of common building materials.
