Outdoor thermal comfort – from steady neutrality to dynamic pleasure
Thermal comfort research has been centred around uni-dimensional thermal neutrality in steady environments for almost a century. This study aims to re-orient the outdoor thermal comfort research discourse towards non-steady-state alternatives that afford greater opportunities for multi-dimensional thermal pleasure compared to steady, uni-dimensional neutrality.
High resolution simulation of microscale urban climate
Large Eddy Simulation (LES) has been used with sub-meter resolution on both idealized arrays of urban canyons and realistic city configurations to obtain detailed 3D data for exchanges of momentum, pollutant, moisture, and heat. This project aims to study pedestrian thermal comfort, pollutant dispersion, urban heat island mitigation, and urban canopy parameterization (UCP).
Maintaining indoor environmental quality (IEQ) is a key priority in educational buildings. However, most studies rely on outdoor measurements and environmental conditions which makes it hard to establish causality and resilience limits. To address this, a fine-grained, low-cost, multi-parameter IoT sensor network was deployed to fully depict the spatial heterogeneity and temporal variability of environmental quality in our educational building in Sydney. The building was particularly selected as it represents a multi-use university facility that relies on passive ventilation strategies, and therefore suitable for establishing a living lab for integrating innovative IoT sensing technologies.
