Adrian Leaman                                         Usable Buildings Trust, United Kingdom


Adrian Leaman has been running Building Use Studies (BUS) since 1987. He is specialized in the management and application of feedback from building occupants about their needs and requirements. The results of his studies are available to property specialists, building designers and managers in briefs and strategic plans for the future. Furthermore, he is an accomplished speaker at conferences, advanced courses and universities in Britain and around the world, and a widely-cited author, with more than 160 publications. He runs the popular website Usable Buildings ( for the Usable Buildings Trust.  In 1998 he was Visiting Professor at the Department of Real Estate and Project Management at the University of Delft, Netherlands. In 2002 he was Visiting Fellow at the School of Architecture and Design, Victoria University of Wellington. From October 2008 to November 2010 he worked part-time with the Building Performance and Systems team at Arup. He has also worked at the Science Policy Research Unit (University of Sussex) (1969-1971), the Royal Institute of British Architects (1972-1977), the Bartlett School (University College London) (1977-78) and the Polytechnic of North London (1978-85).  He has project experience covering over 600 commissions. These include United Nations (UNDP),OECD, Department of Education (UK), Department of Environment (UK), Melbourne City Council, New South Wales Public Works, National Power, DETR (UK), British Airways, Building Research Establishment, Stanhope Properties, Xerox, Nokia, Interior, BiFM, Byggforsk (Norway), TNO (Netherlands), BP, Metropolitan Police Service, Unilever, Arup, Bendigo Bank. He has collaborated with Bill Bordass on many projects in the UK. Their real-world and total building approach to problem solving uses strategic thinking about the future based on careful analysis of current performance and trends. Their respective databases on energy, user, health and occupancy issues are extensive, and have provided the models for many similar studies. Currently, Adrian Leaman is involved in a wide range of projects and initiatives.

dr. Severine Kirchner                                 CSTB le futur en construction, France

S Kirchner[1]

Séverine KIRCHNER has a PhD in atmospheric pollution chemistry and environmental geophysics and graduate from the School of Public Health on “Assessment and management of environmental health risks”.
She is Deputy Director for Research in Health & Comfort Department at CSTB (Scientific and Technical Center for Building). The Department manages research projects funded by public and private sectors on topics related to human exposure and risk management in indoor and    outdoor environments including indoor air pollution, acoustic, vibration, lighting and electromagnetic fields.
She is the scientific coordinator of the French Indoor Air Quality Observatory (Observatoire de la Qualité de l’Air Intérieur, OQAI). Under the supervision of the Ministries of Construction, Housing, Ecology and Health with support from CSTB – operator of the action program – ADEME (French Agency for Environment and Energy) and ANSES (Health Safety Agency for Food, Environment and Labour), OQAI is a national program that produces knowledge about indoor air quality and comfort in various indoor living spaces such as homes, schools, offices and amenities, in order to provide input to the development of public policies to prevent or mitigate the risks in indoor spaces. Author of several publications in this field, she led, in 2011, the publication of the book gathering the 10 years of research conducted by OQAI “Indoor Air Quality, quality of life. 10 years of research to breathe better.”
She chairs several committees at a national level: the Working Group Exposome set up to establish priorities for the 3rd National Environmental Health Action Plan (NEHAP); the Scientific Committee of the National Inter agencies Research Program for Better Air Quality at the Local Scale (PRIMEQUAL) coordinated by Ministry of Environment and French environment and energy management agency (ADEME). She also is the vice-chair of the Expert Committee (CES) “Risk assessment of air pollutants” at the French Agency for Food, Environmental and Occupational Health Safety (ANSES).
At an international level, she participates in several European projects and is a Member of the WHO Steering Committee “Development of WHO Guidelines for Indoor Air Quality”.

Picture W vMLichtenbelt

Wouter van Marken Lichtenbelt is Professor Ecological Energetics and Health at the Department of Human Biology, NUTRIM School of Nutrition and Translational Research in Metabolism, Maastricht University Medical Center+, Maastricht, The Netherlands.
Wouter van Marken Lichtenbelt obtained his PhD at the University of Groningen on ecological energetics of green iguanas. Twenty years ago his research switched from animals to humans, and from the tropical to the indoor environment. Main emphasis is on individual differences in whole body energy metabolism, thermoregulation and health, the underlying mechanisms, and numerical modeling of human thermoregulation. This knowledge is applied in daily living circumstances, i.e. the built environment.
A fundamental aspect of the research line is the human response to cold and warm environments as we may encounter in daily life. An important recent discovery is cold induced brown adipose tissue in adult humans. This tissue can produce heat, thereby protecting us from becoming too cold and may positively affect our body’s energy balance. Other parameters related to disease are also being studied. This part of the research bridges the gap between whole body human metabolic studies and recent insights in energy, glucose, and fat metabolism and its link to overweight and type 2 diabetes.
Much attention is given on how indoor conditions relate to (thermal) comfort, long-term health and prevention of overweight and diabetes.

dr. Miia Pitkäranta                                       Vahanen Group, Finland

Pitkäranta Miia

Dr. Miia Pitkäranta is a Finnish building microbiologist with a background in molecular microbiology and genetics. She earned her PhD at the University of Helsinki in microbiology where she worked in the DNA Sequencing and Genomics Laboratory of the Institute of Biotechnology. Being among the first ones to apply molecular sequencing tools on indoor samples, her research was a cornerstone for studies of the indoor microbiome and provided very first insights into the vast diversity of fungi and bacteria in buildings. After finishing her PhD she studied building sciences and became a practitioner in the building investigations industry. Through this work she developed a comprehensive view on the connection between building physics and microbial ecology of the built environment. Dr. Pitkäranta is currently working as a specialist for healthy buildings at the Building Physics Expert Services unit of Vahanen Group in Finland. Her present activities include e.g. coordinating a major update of a national guidebook for IAQ problems, lecturing and giving building microbiological consultation, as well as managing condition investigations of problem buildings with impaired indoor air quality. She is also involved in academic research in the form of reviewing and committee work, e.g. as the member of the new ISIAQ STC “Microbes in Indoor Environments”.

prof.dr. Christoph van Treeck                     RWTH Aachen, Germany


Christoph van Treeck (Univ.-Prof. Dr.-Ing. habil.) is full professor for energy efficient and sustainable building at RWTH Aachen University in Germany. Before he joined RWTH in 2012, he was head of the Simulation Group of the Department Indoor Environment at the Fraunhofer Institute for Building Physics in Germany and associate professor (Privatdozent) at the Technische Universität München. He has a Ph.D. in computational civil engineering, and is specialized in the fields of computational fluid mechanics, thermal comfort related issues, building performance simulation, and building information modeling. In 2009, van Treeck received the Fraunhofer Attract Award endowed with 2.7 Mio €. He is member of several international standardization committees at DIN and ISO level, member of buildingSmart, member of the European Energy Research Alliance (EERA) within the Smart Cities Joint Program, and serves as reviewer of several international conferences as member of the scientific committees. As well, he serves as member of the board of directors of the International Building Performance Simulation Association (IBPSA) and he is a member of the editorial board of IBPSA’s Journal of Building Performance Simulation.
