Simulated architectural environments provide immense value in technology validation and optimisation in smart buildings. Automated variable acoustics (intelligent acoustic technology) as a novel, emerging technology would benefit largely from simulated environments. Notably, such technology exhibits opportune application for use in classrooms, suggesting the vast benefits of simulated classroom environments for optimisation of intelligent acoustic technology. For such simulations, typical profiles comprising of data on physical and aural NZ classroom attributes have not been holistically detailed or virtually developed. This paper thus aims to develop and detail such virtual environments. Documentation exposing the physicality of classroom types are collated to detail 5 typical classroom profiles. Studies attempting to define regular aural situations in classrooms reveal 4 typical aural situations. Statistical analysis of these quantitative physical and aural classroom attributes produced 2 useful datasets for the acoustic environments. Co-variate adaptive randomization and interpolation were used to create 20 profiled NZ classrooms. This paper offers the development, detailing and demonstration of these ‘typical’ NZ profiles which can be used for software simulation in both industry and academic fields; classroom architecture, classroom acoustics and acoustic optimisation. I-Simpa, a pre/post-processor for acoustic codes, and Autodesk software are used to detail and demonstrate the classroom profiles.
