Indoor Environmental Quality (IEQ) (DESC9201)


Humans' thermal, visual, auditory and olfactory senses determine the perceived quality of a built environment. This unit analyses built environments in context of these human factors. This unit relates human experience of buildings to the main dimensions of Indoor Environmental Quality (IEQ): thermal, acoustic, lighting and indoor pollution. This understanding of human comfort perceptions is contextualised by an understanding of the various approaches to the evaluation of built environmental performance. You will study post-occupancy evaluation tools and workplace productivity metrics. Regulations from Australia and abroad will be explored to understand their impact on acoustics, thermal comfort, lighting, indoor air quality and ventilation. The unit also pays particular attention to sustainability rating tools from around the world, including GreenStar, NABERS, LEED and BREEAM. This unit gives students extensive hands-on experience in laboratory- and field-based methods of IEQ research and building diagnostics. A recurring theme will be instrumental measurements of indoor environments, and how they can be analysed in relation to perceptual and behavioural data collected from occupants of those environments.
