Exploring physics of city ventilation and thermal climate by simulation

Yuguo Li
Chair Professor of Building Environment
Department of Mechanical Engineering
The University of Hong Kong

Yuguo Li is Chair Professor of Building Environment, Associate Dean of Engineering (Research) and former Head of Department of Mechanical Engineering, and Honorary Professor of School of Public Health, The University of Hong Kong. He studied at Shanghai Jiaotong University, Tsinghua and KTH in Stockholm, and was a Principal Research Scientist at CSIRO. His main research interests are on building environment engineering (indoor air quality, city climate, and environment studies of infection). He led the development of 2009 WHO guidelines on natural ventilation.  He currently serves as Editor-in-chief of Indoor Air, and was the President of ISIAQ Academy of Fellows. He received John Rydberg Gold Medal from SCANVAC in 2014, and an Honorary Doctor Degree from Aalborg University, Denmark, 2015 and the Inoue Memorial Award from SHASE Japan in 2016. He was elected a Fellow of ASHRAE, ISIAQ, HKIE, and IMechE.
Weather related hazards such as heatwave and urban warming threatens the living habitats of city dwellers. The hotter urban environment has already led to significant health and energy challenges in cities such as Hong Kong.  Wind and climate at street level in such a city are affected by those at building microscale, and regional mesoscale. The difficulties of simulating climate and environment at microscales in a city are known. A unified micro- and meso-scale approach is on the horizon. Both field measurement and laboratory models are needed and useful to supplement the simulations.

In this talk, the speaker will introduce how building and city simulation has enabled us to understand urban heat island circulation (city heat dome), as affected by earth rotation, inversion and light winds, how two or more heat domes merge, how a stronger heat dome enhances foehn winds and contributes to the heatwaves in Hong Kong, and finally how f sea water cooled air condition systems may reduce the peak temperature during urban heatwaves. The latter may serve as an example how the building simulation community can contribute to urban climate control. The speaker advocates a future of transferring knowledge from building simulation to urban climate design, i.e. a city climate can be designed as a building.



Scenarios for the Future of HVAC in Buildings

Reinhard Radermacher
Professor and Director
Center for Environmental Energy Engineering (CEEE)
Mechanical Engineering, A. James Clark School of Engineering
University of Maryland

Reinhard Radermacher holds a PhD in physics and conducts research in heat transfer and working fluids for energy conversion systems. He is an internationally recognized expert in the use of working fluid mixtures. His research grew to range from environmentally safe refrigerants in residential air-conditioners and heat pumps to combined heating, cooling and power systems for buildings and campuses. He has nearly 40 years of experience in HVAC research resulting in more than 400 publications, numerous invention records and 12 patents. He has co-authored three books. Dr. Radermacher is Minta Martin professor of Mechanical Engineering and director and co-founder of the Center for Environmental Energy Engineering. He was awarded the Institute of Refrigeration J&E Hall Gold Medal and the IIR Gustav Lorentzen Medal for his innovation in the field of refrigeration. He is Fellow ASHRAE and also holds memberships in ASME, SAE, DKV and IIR and serves as the editor of the ASHRAE journal, Science and Technology for the Built Environment.

After a brief discussion of drivers for change in HVAC technology, the presentation will discuss expected advances in HVAC technologies and how these may affect the business and future approaches to how buildings are conditioned. Examples will be discussed and challenges and research opportunities outlined.
