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

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently

implement WHS workplace procedures and practices including the use of risk control measures

demonstrate essential knowledge and skills to complete a building thermal performance survey

demonstrate competency within a timeframe typically expected of the discipline work function and industrial environment

carry out a building survey and load estimate for a multiple zone commercial building

complete a building thermal performance survey for different buildings This must include

minimum five zones

internal and system heat gains

infiltration and fresh air rates

heat flow through windows accounting for internal and external shading

heat flows through building fabric

use of simulation software

Context of and specific resources for assessment

This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM Metal and Engineering Training Package

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application

Assessment may be applied under projectrelated conditions real or simulated and require evidence of process

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency where required

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

WHS requirements

Environmental requirements

Appropriate personnel

Heat gains

Resources and equipment

Industry standards
