Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include:
developing outlines of alternative designs developing the design within the safety, regulatory, functional requirements and budget limitations documenting and presenting design effectively negotiating design alteration requests successfully obtaining approval for final design dealing with unplanned events applying relevant work health and safety (WHS)/occupational health and safety (WHS/OHS) requirements, including using risk control measures designing complex heating, ventilation and air conditioning/refrigeration (HVAC/R) control systems preparing to design complex HVAC/R control systems.

Knowledge Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

Assessment Conditions

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment. Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Resources for assessment must include access to: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, facilities and equipment currently used in industry applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.
