TAS Part E2 Heating, cooling and ventilation systems

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).

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

A heating, cooling and/or ventilation system must support energy efficient outcomes and minimise any impact on building occupants of adjoining spaces, the Network Utility Operator's infrastructure, property and environment.

(1) A mechanical service, plant and equipment for heating, cooling and/or ventilation must avoid the following:

1. Damage to property.
2. Loss of amenity to occupants.

(2) A mechanical service, plant and equipment for heating, cooling and/or ventilation must ensure the following:

1. Efficient use of energy and water.
2. Access for maintenance.

Pressure equipment used in mechanical heating, cooling and ventilation systems must avoid the likelihood of explosion, rupture or leakage.

Mechanical air-handling and cooling water systems installed in a building must control the accumulation of microbial growth.

Performance Requirement E2P1 to E2P3 are satisfied by complying with E2D2.
