Dr Gaëlle Guyot is the deputy head of the research team Performance of buildings in their environment at Cerema, the French public agency for developing public expertise in the field of ecological and energy transition.

She graduated three master’s degrees in 2006-2007 and she received later on her PhD from the Savoie-Mont Blanc University in 2018. Since 2006 at the Cerema, she has been interested in the complexity of the interactions between the different air flows in buildings and their impact on energy, comfort, indoor air quality, the propagation of an accidental toxic cloud, the transmission of viruses and, above all on health. 

Cerema is a place where research actions make it possible to remove obstacles in order to anticipate and support the evolution of regulations in France and in Europe, for buildings that meet the challenges of climate and public health. The improvement of the quality of ventilation and airtightness of buildings, the development of methods to assess the performance of ventilation at the design stage, the sustainability of performance, the development and promotion of promising strategies such as smart ventilation, are her favourite crucial research topics.

She is the co-author of about 50 articles in international journals and conferences and represents France on the AIVC board. She co-supervises several Post-Doc and PhD thesis and have participated in many collaborative projects in France and in Europe. She has been an invited Professor during several weeks/months at LBNL Berkeley lab (USA), Pontifical Catholic University of Paraná (Brasil), and Victoria University of Wellington (New-Zealand). She is Assoc. Prof. at University Savoie Mont Blanc.

Kirsten Gram-Hanssen is a professor at Aalborg University and leading the research group on Sustainable Cities and Everyday Practices. Her research is centered on housing, everyday life and consumption from a climate and energy perspective. She is strongly engaged in transdisciplinary research combining technical and social sciences in finding solutions for a sustainable future. Her results include explaining differences in consumption while emphasizing the importance of both routines and technical infrastructures. She has more than 25 years of experience within this research field and has written numerous papers on the subject. She is a frequent speaker at national and international events and have been project leader of many research project financed by Danish and European research councils, including having received an ERC-advanced grant.

Trond Thorgeir Harsem is working as a consultant at Norconsult, Oslo, Norway and is responsible for the research and development in HVAC. He has earlier been working part-time as associate professor at Oslo Metropolitan University for 10 years with focus on automation and hydronic solution with the goal to reduce the energy consumption in buildings and buildings complex. He has extensive experience in research and development with respect to new as well as old technology, primarily within system design, data programming and bus technology within automation in buildings. He has developed several special programmes within climate, effect and energy consumption of buildings and displacement ventilation in glazed atria. Harsem has been working within most of the HVAC-technical areas and have been designing Hospitals with specialities in operating room and Airborne Infection Isolation room. In this category the focus has been on reducing airborne particle (bacteria and virus) from one room to another. One of the projects called POSI – Reduction of postoperative surgical infection through fusion of Computational Fluid Dynamics and extended reality in operating room will be presented.  Most of the research project have been funded by the Norwegian research council.

 

Benjamin Jones is an Associate Professor at the University of Nottingham’s Department of Architecture and Built Environment.  The focus of his work is on measurement and modelling approaches to the indoor environment that can inform policies to create low-carbon and healthy building stocks. He is particularly interested in the energy efficient ventilation of buildings and its relationship with indoor air quality and occupant health.

Ben participated in the pandemic responses of the UK and Chilean Governments, the AIVC, the CIBSE, and ASHRAE. Recent research has included the measurement of particulate emissions from the cooking of foods, the development of housing stock models to assess indoor air quality, and the development of harm based indoor air quality metrics.

Dr. Ying Xu is a Distinguished Guoqiang Associate Professor in the Department of Building Science at Tsinghua University, China. Prior to her position at Tsinghua University, Dr. Xu was a tenured Associate Professor at the University of Texas at Austin. Dr. Xu has been serving as the President of the International Society of Indoor Air Quality and Climate (ISIAQ) since 2022, the Chair of ISIAQ scientific and technical committee 11: Sources, Monitoring and Evaluation of Chemical Pollutants, and the Associated Editor for Journal of Exposure Science & Environmental Epidemiology.    

Dr Xu’s research is focused on understanding the relationships among sources, indoor environments, and human health for indoor pollutants, especially semi-volatile organic compounds (SVOCs). She has served as principal investigator and co-principal investigator on research projects funded by the NSF of China, the Ministry of Science and Technology of China, U.S. NSF, U.S. EPA, ASHRAE, and NIOSH, ranging from emissions of SVOCs (e.g. plasticizers, flame retardants, and biocides) from building materials and consumer products, interactions of SVOCs with indoor aerosols, and the transport and human exposures associated with emerging contaminants in indoor environments. Dr. Xu and her research team have published over 100 papers in top journals of environmental engineering and in conference proceedings. Two of her journal publications were selected for special honors, one as the Editors’ Choice Article by the American Chemical Society (ACS) and the other in the “Science Selections” by the journal Environmental Health Perspectives. Dr. Xu’s research was highlighted by the media, including the Daily Mail, Fox News, the U.S. NSF homepage, and Austin American-Statesman. Her research results were also reported in U.S. NSF Discoveries as a special science news program. Dr. Xu is the recipient of numerous awards and honors, including the Yaglou Award (2011) from ISIAQ for being the most promising young researcher in the field of indoor air sciences, U.S. NSF CAREER Award, New Investigator Award from the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the Air and Waste Management Association (A&WMA) Outstanding Doctoral Dissertation Award (2015), Virginia Tech Outstanding Young Alumni Award (2016), and Best Paper Awards from ISIAQ (2014), A&WMA (2014), the International Society of Exposure Science (2008) and in Healthy Buildings 2006.
