    WS1: Thermal Physiology and Comfort. Chairs: Wouter van Marken Lichtenbelt and Ken Parsons

    Thermal comfort and thermal physiology are linked to each other. In the last decennia much new information has been gained on thermal physiology. In the past ergonomic studies mainly focussed on extreme temperatures. Gradually more information is being gathered on the effect of moderate temperature variations on our physiology, thermal sensation and comfort experiences. However there remains a dearth of information on temperature drifts and temporal switches in ambient temperature. Another aspect that deserves attention is health as very little is known about the long-term effects of ambient temperature on our health. Are comfortable temperatures healthy? It is becoming apparent that excursions outside the thermal comfort zone can be beneficial. Cold or warm acclimated subjects are better able to cope with heat and cold waves and it has been shown that mild cold is beneficial with respect to the metabolic syndrome. The workshop intends to explore where we are in relation to such issues and discuss new directions for research on the link between thermal comfort and physiology and related health issues.

    WS2: Understanding Comfort, Attitudes and Behaviours. Chairs: Da Yan and Atze Boerstra

    Occupant behavior is now widely recognized as a major contributing uncertainty factor in building performance. Due to the complexity and unpredictability of an individual occupants responses, it is difficult to simulate occupant’s behaviour influenced as they are by physical, physiological, psychological and other factors. There still are many gaps in our knowledge of the field and limitations to current methodologies applied by researchers and practitioners to integrate occupant behaviours at the design, operation, and retrofit of buildings stages. This workshop focuses on understanding of, and also the modelling and simulation of occupant behaviour in buildings. The IEA Annex 66: Definition and Simulation of Occupant Behaviour in Buildings, will also be introduced. Attendees will discuss the progress of occupant behaviour research in buildings, which including robustness experiment design, advanced modelling development, rigorous model evaluation, etc., with a view to stimulating in-depth discussions on methodologies of occupant behaviour modelling and simulation.

    WS3: Thermal Comfort with Radiant and Convective Systems. Chairs: Risto Kosonen and Caroline Karmann

    Radiant systems are often considered to provide better thermal comfort than air systems due to their active control of the mean radiant temperature. Yet beyond this theoretical explanation, what do we really know about thermal comfort for both systems? This workshop will begin with the results of a critical literature review on thermal comfort for radiant compared to all-air systems. In rooms with high heat loads (high cooling demand) it becomes challenging to achieve the targeted indoor climate without sacrificing occupants’ thermal comfort due to the increased convective flows (high volumes of air supplied). Therefore cooling systems based on convective, radiant or combined heat exchange are used. During this workshop, the differences between them will be discussed and also the performance of four systems based on radiant and convective cooling – chilled beam (CB), chilled beam with radiant panel (CBR), chilled ceiling with ceiling installed mixing ventilation (CCMV) and radiant cooling panels with ceiling installed mixing ventilation (MVRC) – compared with regard to the generated thermal environment and human responses.

    WS4: The Role of Clothing in Comfort. George Havenith and Roberto Lamberts

    Today in cold climates we often see very high set point temperatures during winter and very low ones during summer, but both energy savings and enhanced comfort can be achieved simply through the use of appropriate and effective clothing behaviours. The CoolBiz and Setsuden programmes in Japan provide new field data that demonstrate that in the summer higher temperature set points can be comfortably adopted in conjunction with changes in clothing behaviours, so avoiding, in some climates the need for heating systems completely. New clothing technologies also require new measurement approaches and protocols. What are the differences in insulation values provided to men and women by clothing? What parts of the body should be covered? Are current tables of clothing thermal resistance adequate? How can the seasonal impacts of different traditional clothing assemblages be accounted for? The workshop provides a forum for discussion of research advances in the field and explores new directions of investigation to fill in knowledge gaps.

    WS5: Domestic Comfort in Different Climates. Chairs: David Shipworth and Hom Rijal

    While the majority of comfort studies have been done in non-domestic buildings, there is considerable data on internal (ambient) temperatures in domestic environments from different climate regions around the world. This data shows surprising spatiotemporal variability within dwellings, and variability between dwellings at any given time. There is substantially less comfort data, but where comfort data is also available, occupants frequently report being comfortable at temperatures well outside those expected by the established models. The lack of comfort data makes interpretation of ambient temperature data problematic. Interpretations range from suggesting that occupants are adopting a wide range of adaptive behaviours ranging from whole-house temperature control to local (personal) adaptive measures to create comfort; through to occupants being substantially uncomfortable for considerable periods in their homes. This workshop will start with presentation of temperature and comfort data from countries including the UK and Japan, and will then flow into a discussion of the interpretation of the data in terms of its variability, and its implications for our understanding of occupant comfort in homes in different climate regions.

    WS6: Putting People into Building Comfort Models. Chairs: Boris Kingma and Paul Touhy

    This workshop deals with modelling thermal comfort and aims to harvest ideas and allow space for discussions around the challenges of representing the wide variability of people into building comfort and energy models. This includes the identification of sub-populations that can be stratified by age, gender and body composition (e.g. lean vs. obese). The workshop will focus on 1) physiological differences between these sub-populations, and the consequences on thermal demand & health, 2) commonly used software packages of building comfort and energy models, and how they should be adjusted to better represent all occupants, their comfort demands, and impacts on energy use etc. so that comfortable low energy buildings can be achieved.

    WS7: Teaching Comfort: Approaches and Tools. Chairs: Stephano Schiavon and Runa Hellwig

    Teaching comfort or how to design a satisfactory indoor environment has become an essential part of the curriculum in many undergraduate and graduate programs in architecture and building science and technology. Using the example of thermal satisfaction the workshop aims to open a discussion on the challenging task to teach this topic. The human perception of the thermal environment is more complex and nuanced than requirements defined in standards, guidelines or sustainability rating systems imply. The multidisciplinarity of the topic comprises heat transfer aspects, physiological and psychological aspects and the translation into a certain design for the built environment. The easiest way to teach this topic is just to report on the requirements and follow these requirements like a cooking recipe, providing numbers which seem to be exact and can easily be interpreted as definite limits. But satisfaction with the thermal environment is different: it is complex; there is impact from the climatic background, from the cultural experience, it is highly individual and varies with time. The solutions humans have been using to make themselves comfortable in the built environment are as diverse and colourful as the architectural solutions of our vernacular built environment is. The workshop will provide examples how this diversity could be taught by making use of comfort tools, such as the CBE Thermal Comfort Tool, and by providing the students the opportunity of experiencing diversity by their own. These examples should serve to open an intensive discussion on what are the challenges and how to master these challenges.

    WS8: Using Statistics Correctly to analyse Comfort and Behaviours. Chairs: Jane and Rex Galbraith

    We shall open the workshop with an introduction to summarising and displaying thermal comfort data and a discussion of how such data might or might not provide answers to questions of interest. Participants will be invited to join in the discussion with questions and alternative solutions where appropriate in a wide ranging, expert and open debate on the challenges of applying statistics to comfort research. We request that participants send examples, with questions and comments, of issues that they have encountered in the analysis and interpretation of thermal comfort data to Jane Galbraith j.galbraith@ucl.ac.uk by 7th March. As well as using appropriate examples in the workshop we hope to provide statistical support to those who contribute examples.

    WS9: Comfort in Ventilated Spaces. Chairs: Jarek Kurnitski and Adrian Pitts

    This workshop is dedicated to comfort in highly ventilated spaces. Such spaces are often in retail stores, where ventilation in high rooms may or may not be used for heating and cooling purposes (all air systems or other systems), or in transition spaces (foyers, lobbies, corridors, atriums, etc) in other non-residential buildings. In highly ventilated spaces there is normally a higher than average level of air movement; avoiding stagnant zones and controlling stratification are issues in varying conditions. Another common area is in comfort for warm humid climates where high ventilation rates are commonly used. In such circumstances the convective effect is much enhanced and will impact on the heat transfer from the body. Because of the high ventilation rate the amounts of energy required to maintain comfort can be high (both for heating and cooling); one option may be to compensate for lower (or higher) air temperatures by use of modified radiant temperature so as to balance the body heat flow. But such radiant impacts and asymmetries can have their own negative impacts. The workshop will discuss the occupant perception and other comfort parameters in highly ventilated spaces or in those where radiant temperature is used to attempt to compensate for the air temperature. Among parameters under interest, the impact of odours on occupant perception of ventilation needs will also be explored.
