Keynote session Wednesday 26 August:

How the COVID-19 pandemic will reshape the built environment

This keynote session is arranged by Technical University of Denmark.

Keynote speaker: Xudong Yang, Professor and Associate Dean, School of Architecture, Tsinghua University, China

How to make the built environment safe
The outbreak of COVID-19 has reminded us the basic question that may have long been overlooked: are our built environments really safe? Attention must be paid to the increasing sensitivity of the public to potential health implications of the built environment. The presentation first analyzes the range of ventilation dilution rates in a number of SARS and COVID-19 infection and non-infection cases. Different levels of ventilation requirements for “regular” air quality and infectious disease transmission control are discussed. Means to achieve different levels of goals are discussed with specific examples. The presentation will conclude by listing a number of opportunities and challenges to make built environments safer. The presentation will also propose some ideas how to make simulation tools readily useful rather than simply academic exercises.

Dr. Yang is presently the Professor of Building Science and Associate Dean in the School of Architecture, Tsinghua University, China. His research interests center on fundamental and practical aspects of indoor environmental quality and sustainable buildings within the following thematic areas: (1) understanding and modeling various indoor air pollutant sources and sinks; (2) immunized technologies for the built environment, and (3) energy intervention and environmental improvement in urban/rural communities. Dr. Yang is a Fellow of American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), and Fellow of International Society of Indoor Air Quality and Climate (ISIAQ). He currently serves as the editor of Building and Environment, founding Editor-in-Chief emeritus of Building Simulation, an executive committee member and representative of China in the IEA-EBC (Energy in Buildings and Communities), and various Chinese ministries and cities. Dr. Yang has received numerous awards including the Research Career Award from the US CDC (2000), the New Investigator Award from ASHRAE (2000), the Advance in Science and Technology award from the Chinese Ministry of Education (2000), the ASHRAE Distinguished Service Award (2008), the Award for Natural Sciences from the Chinese Ministry of Education (2013), and the ASHRAE Exceptional Service Award (2018).

Keynote speaker: Dr. Andrew Persily, U.S. National Institute of Standards and Technology (NIST), USA

The Role of Airflow and Contaminant Transport Simulation in Making Buildings Safer
The need to maintain the safety of building occupants in light of the COVID-19 pandemic and other challenges, both known and unanticipated, has again highlighted the impacts of ventilation and airborne contaminant transport on human exposure. This presentation will discuss how building airflow and contaminant transport simulation can support efforts to make building’s safer in response to various airborne contaminant exposures. It will start with a brief review of airflow and contaminant transport simulation, followed by examples of the application of simulation tools to specific airborne hazards such as smoke management in response to building fires and the threat of intentional biological and chemical releases. The presentation will discuss how simulation tools can be used to address exposure risks associated with airborne contaminants, including understanding exposure and disease transmission events after they have occurred and studying the effectiveness of control measures intended to reduce these exposures. A number of challenges in the application of existing simulation tools to these questions will also be reviewed including the availability of input data, zones with nonuniform contaminant concentrations, coupling with HVAC simulation tools and more detailed models of airborne contaminant transport mechanisms.

Dr. Andrew Persily is Chief of the Energy and Environment Division at the U.S. National Institute of Standards and Technology (NIST), where he has worked for four decades after earning a Ph.D. in Mechanical and Aerospace Engineering from Princeton University. His research has focused on indoor air quality and ventilation in commercial and residential buildings, including the development and application of measurement techniques to evaluate airflow and indoor air quality performance and of multi-zone airflow and contaminant dispersal models. He has published more than 300 journal articles, conference papers and NIST reports. Dr. Persily was a vice-president of ASHRAE from 2007 to 2009, and is past chair of ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality) and Standard 189.1 (Design of High-Performance Green Buildings). He is a Fellow of ASHRAE, ASTM and ISIAQ, and recipient of the NIST Bronze, Silver and Gold medals.

Keynote session 27 August:

Bio-based materials - benefits and challenges

This keynote session is arranged by BUILD - Aalborg University.

Professor Dominique Derome

Keynote speaker: Professor Dominique Derome, Université de Sherbrooke, Canada

Dominique Derome is professor at the Department of civil and building engineering, Université de Sherbrooke, Canada, and holds a Tier 1 Canada Research Chair tier 1 in Multi-scale Building Physics. She looks at heat and mass transfer processes in the built environment, the related impacts on durability of materials (namely wood) and on thermal comfort and its inhabitants. Her research proposes innovative and multi-scale approaches of the highly coupled physical processes that occur in the built environment, intensively integrating advanced computational and experimental methods. This multidisciplinary research leads to solutions developed for a sustainable living environment, resilient in the face of climate change, possible higher risks of heat waves and impacts on the urban environment. Previously she was for 11 years senior scientist at the Swiss research institution Empa (2008-2019) and 10 years professor at Concordia University, Montreal, Canada. She is the Editor-in-Chief of the Journal of Building Physics.
