Abstract

This document sets out design requirements for mechanical air-handling systems that ventilate buildings and car parks (see Note 1), and requirements for ventilation based on the need to control odours, particulates and specific gases (e.g. CO, NOx, CO2, VOCs, SO2, O3). This document does not include requirements — (a) associated with comfort (e.g. temperature, humidity, air movement or noise); (b) for the maintenance of ventilation and air-handling systems; (c) for natural ventilation systems, apart from natural make-up or relief to mechanical systems (see Note 1); (d) for the elimination of condensation; (e) for the provision of ventilation to ensure the safe operation of gas appliances; and (f) for safety aspects associated with fire and smoke. (g) for control of infectious aerosols. NOTE 1 Requirements for natural ventilation of buildings (including car parks) are covered by AS 1668.4 and the National Construction Code (NCC). NOTE 2 Road tunnels and other non-building related applications are outside the scope of this document. NOTE 3 Fire and smoke control aspects of air-handling systems are covered in AS 1668.1. NOTE 4 Requirements for system design in respect of microbial control are given in AS/NZS 3666.1. NOTE 5 Air-handling systems should be designed, constructed and installed so that their use does not give rise to a noise or vibration nuisance. For guidance on noise and vibration control, refer to AS 1055.1 and AS 2107. NOTE 6 Information on thermal comfort conditions is given in ISO 7730 and ASHRAE 55. NOTE 7 This document covers the design of ventilation systems for industrial processes. NOTE 8 Requirements for ventilation in relation to the safe operation of gas appliances are covered in AS/NZS 5601.1. NOTE 9 For further guidance regarding infectious aerosols, refer to ASHRAE 241.
