Abstract: The majority of information regarding naturally ventilated CFD modelling calibration processes focus on small spaces, with ceiling heights less than 3.5m, and office type occupancy levels. Dense occupation of a space, with multiple levels of seating in the same volume and a substantial ceiling height, leads to stratification of air temperatures. This stratification can create extreme differences in occupancy comfort within the same space. Through analysis of the Royal Wanganui Opera House, this paper discusses the process of calibrating CFD models of naturally ventilated auditoria. By following this calibration process, the results of CFD simulations can be quality assured and therefore enable a degree of trust for the predictions of natural ventilation strategies proposed for large spaces.
