The Environmental Modeling Capability Group’s primary objective is to conduct research and support industry over a myriad of environmental issues, focusing on urban heat island impact, energy efficiency solution and the national green-mark building thrust.
Our environmental modeling adopts a multi-scale, multi-physics approach. It ranges spatially down from urban scale (~10 km), district scale (~1 km), building scale (~100 m), up to indoor/room scale (~10 m) and finally to human scale (~1 m). It also involves thermal storage transfer between the modeling objects and ambient environment, radiation, and thermal transfer. The research integrates multi-disciplinary fields with scientists from CFD, environmental, atmospheric, energy, building engineering, and health care professions.
Our four key research areas are:
- Urban airflow dynamics
- Building flow and ventilation
- Indoor and urban pollutant dispersion
- Fire dynamics
Our environmental modeling is applied to climate change impact & urban planning analysis, building energy efficiency & integrated design tool, risk analysis & mitigation, air quality & health assessment.
We develop computational algorithms and tools to solve specific environmental applications. Our group works with various government agencies; as well as private companies. Typical projects include air quality modeling, climate change impact, urban CFD, HVAC design, fire and smoke assessment, thermal comfort evaluation studies, public health assessment, biodiversity and water resource management.
