Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

relevant state, territory and local authority planning and other approval documents
standard industry reference materials
technical reports.
Documentation may be accessed from:
building and planning authorities
commonwealth, state, territory and local government agencies
libraries
online catalogues and directories
websites.
Preparation for measurement tasks may include:

liaise with relevant personnel to arrange site access
prepare measuring and safety equipment
undertake risk assessment.
Measuring equipment may include:
calculators
rulers, including laser rulers
tape measures
trundle wheels.
Measurements may include:
linear measurements in metric scale
measurements for calculating areas and volumes of regular and irregular shapes that are relevant in conducting thermal performance assessments, such as rectangles, squares, circles, triangles, trapeziums, cubes, cones, pyramids and cylinders.
Recorded may include:
annotations
electronic data entry
sketches
written notes.
Preparation for building appraisal may include:
arrange transport

building extensions and modifications, both approved and unapproved
building materials
conformance of actual building to building drawings
external elements and properties
site constraints in accessing parts of the building for data collection
sufficient information to ensure reliable data for NatHERS assessment purposes.

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 gathering supporting information required to undertake thermal performance assessments. This includes taking on-site measurements, appraising buildings, and sourcing relevant documentation.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person should demonstrate the ability to:
conduct on-site measurements and collect data to gather information for NatHERS assessments
conduct building appraisals to gather information for NatHERS assessment
identify, source and extract information from documents for use in conducting NatHERS assessment
follow established work practices and use personal protective equipment to ensure safety and security of self, others and property when conducting on-site data gathering activities
demonstrate environmentally sustainable practices.
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:
relevant codes, standards and government regulations
access to residential buildings from which building information required for conducting a building thermal performance assessment may be obtained
computer hardware and software suitable for searching online catalogues for documentation relating to NatHERS assessments
technical reference library with current publications on passive building design, thermal performance of building materials and buildings, NatHERS, and manufacturers’ building product information.
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 gathering supporting information required to undertake thermal performance assessments, by:
taking on-site measurements
appraising buildings
sourcing relevant documentation.
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.
