Elements and Performance Criteria

  1. Confirm potential measures for improving thermal performance.
  2. Gather information on cost of measures to improve thermal performance.
  3. Analyse cost of measures to improve thermal performance.

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.

Measures for improving thermal performance of residential buildings must include at least three of the following:

construction materials

draught proofing

floor coverings

glazing

insulation levels

landscaping and planting

orientation

passive cooling

passive design

passive solar heating

shading

skylights

structural changes

thermal mass

ventilation

windows:

coverings

size

type

building zoning and layout.

Factors that may influence costmust include at least three of the following:

availability

building design

building siting

building type

changes in product and service specifications

changes in professional fees

condition of building

date of order or purchase

delays in supply

foreign exchange movements

guarantees

insurance

labour costs

product changes and upgrades

service changes and upgrades

source of supply

taxes and charges

transport and handling costs.

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 determine the cost of measures for improving the thermal performance of two different residential buildings based on the outcomes of a Nationwide House Energy Rating Scheme (NatHERS) assessment.

In doing the above, the person must:

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.

Knowledge Evidence

A person demonstrating competency in this unit must demonstrate knowledge of:

factors involved in providing cost measures to improve thermal performance of residential buildings:

ethical practices in identifying suppliers and product and service information

product and service knowledge:

benefits and limitations of products and services

inclusions and exclusions in products and services

rebates and other forms of assistance for products and services that enhance thermal performance of residential buildings

specifications
