Description
This unit applies to individuals responsible for the evaluation and design of air conditioning and ventilation systems.The unit requires application of technical skills and knowledge to design, size and document details for complex air conditioning and ventilation systems for residential and commercial applications. The role may involve interaction with architects, builders, suppliers, clients and relevant planning authorities and requires a sound understanding of applicable legislation, standards and codes.The unit requirements are typically carried out by a consultant or person in a supervisory capacity in relation to plumbing services and hydraulics.It applies to those who design air conditioning on a new project or an existing structure.In some jurisdictions, this unit of competency may form part of accreditation, licensing, legislative, and regulatory or certification requirements.
