Description
This unit specifies the skills and knowledge required to design complex (non-solar) heated water supply and distribution systems for buildings with 29 floors, inclusive of basement and fixtures on each level for residential, commercial and industrial applications. The unit includes circulating systems, fuel and energy loads and system selection.The role may involve interaction with architects, builders, suppliers, clients and relevant planning authorities and requires sound understanding of applicable legislation, standards and codes.This unit’s requirements are typically carried out by experienced tradespeople such as hydraulic design consultants or persons in a supervisory capacity in relation to plumbing services.In some jurisdictions, this unit of competency may form part of accreditation, licensing, legislative, regulatory or certification requirements.
