Objective

Tas GO1

The Objective of this Part is to—

  1. safeguard people from illness, injury or loss (including loss of amenity) due to the failure of a heating, ventilation or air-conditioning installation; and
  2. ensure that a heating, ventilation or air-conditioning installation is suitable; and
  3. conserve water and energy; and
  4. safeguard the environment; and
  5. safeguard public and private infrastructure; and
  6. 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).

Functional Statements

Tas GF1.1

Mechanical services, plant and equipment used for heating, cooling and/or ventilation of a building must be adequate.

Tas GF2.2
