Summary

Green Star rating under the green building council of Australia is increasingly considered and demanded by the building developers. One of the Green Star rating categories is air change effectiveness (ACE). Two points are awarded if ventilation systems are designed to achieve ACE of at least 95% of the net lettable area when measured in accordance with ASHRAE 129-1997. During the design stage this can only be demonstrated through computational fluid dynamics modelling of the air conditioning system other than the nominated DTS criteria. This study summaries the factors affecting ACE and provides design guidelines to assist in achieving compliance with the GBCA ACE requirements. The effect of return air plenum on ACE is discussed.
