VIC Part E2 Heating, ventilation and air conditioning systems
Introduction to this Part
This Part sets out the requirements for the design, construction, installation, replacement, repair, alteration and maintenance of mechanical heating, cooling and ventilation systems.
VIC E2O1 Objective2019: GO1
The Objective of this Part is to—
- safeguard people from illness, injury or loss (including loss of amenity) due to the failure of a heating, ventilation or air-conditioning installation; and
- ensure that a heating, ventilation or air-conditioning installation is suitable; and
- conserve water and energy; and
- safeguard the environment; and
- safeguard public and private infrastructure; and
- ensure that a heating, ventilation or air-conditioning installation is designed and is capable of being maintained so that throughout its serviceable life it will continue to satisfy Objectives (a) to (e).
VIC E2F1 Functional statement 12019: GF1.1
