The first day of the three-day event started by four keynote talk in the morning, followed by the OB-16 symposium where 21 researchers and practitioners presented their latest work on various themes of occupant behavior research. Among the keynotes, the CEO of Ecobee, Stuart Lombard, discussed the sharing of occupant behaviour data with researchers. Isis Bennet of Carleton University and Brandon Malleck of Bentall Kennedy presented on the challenges of motivating occupants to reduce plug loads. During the next two days of the Ottawa meeting, the subtask leaders reported and discussed the overview of activities in each subtask. The arranged break-out sessions and panel discussions for each subtask allowed participants to present and discuss about the work plan for deliverables of each subtask in more details. The contributors to the Annex 66 exchanged their ideas on the outline of the final Annex 66 report. The potential for future international multi-disciplinary collaboration under a new Annex with focus on the applications of the Annex 66 outcomes was also discussed.

IEA-EBC Annex 66 3rd Expert Meeting, TU Wien, Vienna, Austria
by Ardeshir Mahdavi, 4/13/2016
The IEA-EBC Annex 66 3rd expert meeting in the working phase was hosted by Professor Ardeshir Mahdavi, Department of Building Physics and Building Ecology at TU Wien, Vienna, Austria. The three-day meeting took place from March 30 to April 1, 2016. More than 60 participants from 22 countries (namely, Austria, Belgium, Canada, Czech Republic, China, Denmark, France, Germany, Hong Kong, Hungary, Italia, Japan, Netherlands, New Zealand, Norway, Poland, Singapore, South Korea, Switzerland, Turkey, UK, and USA) attended the meeting.
The first day of the meeting was allocated to an International Symposium on People's Behavior in Buildings, with 3 keynote speakers in the morning and two PhD presentation sessions in the afternoon. Altogether, 16 doctoral students presented the latest result of their occupancy-related research work. In the following two days, Annex 66 participants reported on the progress of activities within Subtasks A to E. Panel discussions, structured sub-task breakout sessions, working lunch meetings, and informal encounters provided ample opportunities to discuss progress to-date and project future steps. The meeting benefited from the prevailing good weather and the rich backdrop of the historical city of Vienna.
ASHRAE approved a new multi-disciplinary task group on occupant behavior in buildings
At the ASHRAE conference in Orlando in January 2016, ASHRAE approved a new multi-disciplinary task group on occupant behavior in buildings (MTG.OBB). The MTG will coordinate TC/TG/TRG technical activities to help implement the recommendations from this MTG. This includes coordinating efforts in education, modeling, research, standards, marketing, advocacy, and fund raising within ASHRAE. Research project initiation as the sponsoring committee is included in the scope of this MTG.
MTG.OBB is concerned with understanding occupant behavior in buildings and meeting individual needs of indoor environmental quality (IAQ, thermal, visual and acoustic comfort), health, productivity, as well as improving occupant interactions with building energy and control systems to reduce energy use.
MTG.OBB will sponsor and coordinate activities of related ASHRAE technical and standards committees to facilitate development of data, tools, technologies, and guidelines enabling integration of occupant behavior in the design, operation, and retrofit of new and existing commercial and residential buildings. The intent is that these products, focusing on the human dimension, may be used in the life cycle of buildings and potentially contribute to ASHRAE’s energy saving targets, by demonstrations of behavior-driven passive and active building designs and identification of energy saving opportunities from behavior measures. Within ASHRAE, the MTG will coordinate activities to update related parts of ASHRAE Handbooks and Standards (particularly energy and indoor environmental calculations, standards 55, 62.1, 62.2, 90.1, 90.2 and 189.1), and to develop related education programs for buildings designers, operators and occupants. Outside of ASHRAE, the MTG will monitor related activities (e.g. IEA EBC Annex 66) and represent ASHRAE interests where permitted to provide a conduit for related information transfer to ASHRAE members.
Individuals and parties interested in joining the MTG, please contact Chair Dr. Tianzhen Hong (firstname.lastname@example.org) or Vice Chair Dr. Da Yan(email@example.com). The committee will meet at the ASHRAE St. Luis conference in June 2016.

After highly successful preparation phase meetings in Hong Kong and Great Britain, the International Energy Agency/Energy in Buildings and Communities Programme (IEA EBC) Annex 66 formally met again on March 30, 31 and April 1 2015 at LBNL in Berkeley, CA, USA. Annex 66 is composed of a group of about 90 researchers from around the world who specialize in the technical aspects of occupant behavior in buildings. The three-day event, included an International Technical Forum, a symposium that allowed leading researchers to present their latest work, followed by two-days of annex meetings to discuss research progress and plans.
Lawrence Berkeley National Laboratory (LBNL) host of the International Technical Forum and Annex 66 meetings
The International Technical Forum included a kick-off introduction by LBNL Staff Scientist, Richard Diamond and co-operating agents, Tianzhen Hong and Da Yan. This was followed by a Department of Energy (DOE) panel on “Envisioning future occupants: A discussion panel for the DOE Buildings of the Future project” and a moderated session entitled “What role might the US government play in supporting occupant behavior research?” This was followed by 8 invited oral presentations from presenters in industry and academia, including engineering and social sciences and from the US, Japan, Germany and Austria. Major categories of topics included occupant modelling approaches, comfort studies, occupant behavior implementation strategies, and case studies. A second annual Symposium on Occupant Behavior, (OB-15) is planned to take place in Germany in August of 2015 in conjunction with the Annex 66 Second Experts Meeting of Working Phase.
Following the International Technical Forum, 72 Annex 66 researchers, from 16 countries (i.e. the Netherlands, USA, Denmark, Hungary, Norway, China, UK, France, Italy, Canada, Austria, Portugal, New Zealand, Germany, Japan, and Brazil) met for an intensive two-day meeting. This was the first meeting in which all the subtask leaders were in attendance. On the first day of the Annex meetings, 34 short presentations were given including overviews of the progress of each subtask and presentations on each activity which will contribute to the final report.
On the second day five subtasks (A: Occupancy; B: Residential Buildings, C: Commercial Buildings; D: Modeling Tools; and, E: Applications) met in break-out sessions. During the break-out sessions, researchers presented on work applicable to the subtask topic. In addition, discussions on the current status of the field and challenges were addresses. In several cases, Annex participants have arranged to work across subtasks on different activities, with the subtask leaders acting as mainly champions for activity completion. The activities include documentation and standards on data collection, modelling methodologies, and model verification.
Other ongoing activities within Annex 66 include: the development of an occupant behavior data repository and outreach and dissemination to the research and construction communities through workshops and conferences.

Occupant Behavior in Buildings: A Seminar at ASHRAE Seattle Conference
By Tianzhen Hong, July 4, 2014
Technologies alone do not guarantee low energy buildings. Occupant behavior plays an essential role in the design and operation of buildings, but it is quite often oversimplified. Occupant behavior refers to an occupant's movement and responses to discomfort, when his/her comfort needs are not met. Occupant behavior varies with time, space and individual, and is influenced by social context. It is random, complex and multidisciplinary. Having a better understanding and robust modeling of occupant behavior in buildings can improve the accuracy of building simulations and guide the design and operation of buildings.
A seminar (Seminar 15, sponsored by TC 4.7 Energy Calculations and TC 2.1 Physiology and Human Environment) was organized on June 30, 2014 during the ASHRAE Conference in Seattle. About 100 people attended the seminar and many expressed strong interest in participating in or being kept informed of the Annex 66 activities.
Dr. Da Yan from Tsinghua University, China presented an overview of IEA EBC Annex 66, Definition and Simulation of Occupant Behavior in Buildings. Annex 66 aims to tackle fundamental issues of occupant behavior research focusing on: behavior data collection, behavior model development, model validation, and applications to improve building design, operation, and retrofit to reduce energy use. Annex 66 attracts more than 50 institutes from 22 countries. More information is available at annex66.org.
Prof. Clinton J. Andrews, from the State University of New Jersey, presented agent-based modeling of occupant behavior. This presentation shares a simulation model that incorporates occupant behavior as an integral component of a building's performance dynamics. It couples an agent-based model of occupants??adaptive responses to comfort conditions, calibrated with behavioral observations and survey data, to a detailed EnergyPlus model of a commercial building. It applies this framework in two situations: (1) assessing the behavioral robustness of alternative building system designs, and (2) fine-tuning the operational strategy for an existing building given a desire to balance comfort and energy efficiency. The agent-based simulation framework implements a Belief-Desire-Intention model of human decision making that includes organizational considerations.
Dr. Tianzhen Hong, from Lawrence Berkeley National Laboratory, introduced a technical framework to standardize the description and modeling of occupant behavior in buildings. The framework has four components: (1) the Drivers behind occupant behavior; (2) the Needs of occupants; (3) the Actions that occupants perform when their needs are not fulfilled; and (4) the Systems with which an occupant can interact to satisfy their needs. Examples and use cases of the framework were introduced, including its use to improve simulation results and as part of the research under the Annex 66. (Dr. Bing Dong, from University of Texas at San Antonio, made the oral presentation.)
Prof. Bjarne W. Olesen, from Technical University of Denmark, presented an overview of occupant behavior research at the Technical University of Denmark.
Second conference call with subtask leaders
Second conference call with subtask leaders took place on 6/30/2014. The call focused on preparation for the Nottingham meeting as well as progress of each subtask. An agreement was reached to focus on four key challenges of behavior research: data collection, model development, model validation, and applications to reduce energy use in buildings.
Dr. Da Yan reported the progress of Annex 66 to the Executive Committee of IEA EBC on June 11, 2014.
Dr. Tianzhen Hong introduced Annex 66 and behavior research at LBNL to IBPSA San Francisco Bay Area Chapter on June 10, 2014. About 40 building designers, engineers, and energy modelers attended the June Event.
IEA EBC Annex 66: Definition and Simulation of Occupant Behavior in Buildings holds first Experts Meeting in Hong Kong
By: Liam O'Brien, March 17, 2014
It is well-established in the building simulation community that occupant behaviour represents one of the greatest impacts on building performance. An international collaborative effort is needed to set up a scientific framework of occupant behavior simulation and definition. IEA EBC Annex 66, the first Annex to focus exclusively on occupant behavior simulation, had its first Open Forum and Experts Meeting on March 12 to 14 in Taikoo Place in Hong Kong. The purpose of the meeting was to solidify the objectives of the Annex and to develop a detailed work plan. In total, 39 researchers and industry professionals from 13 countries attended the three-day meeting.
Annex 66, titled Definition and Simulation of Occupant Behavior in Buildings has set out the mandate to support more accurate building design and operation through the standardization of occupant monitoring, modelling, and simulation. The Annex is led by Dr. Da Yan of Tsinghua University and Dr. Tianzhen Hong of Lawrence Berkeley National Laboratory, the Operating and Co-operating Agents. It is further divided into five subtasks as outlined in Figure 1. Three parallel subtasks are working on occupancy (presence and movement), residential building occupants, and commercial building occupants modelling. The three subtasks have also joined forces to establish standard protocols for occupant monitoring (e.g., sensing and experimental design) and modelling approaches. Furthermore, they are establishing a database of high-quality monitored occupant behaviour data that will be open to other researchers.
Figure 1: Annex 66 research structure
Subtask D is focused on developing methods to implement occupant behaviour models into established simulation engines so that they can be more accessible to researchers, designers, and facilities managers. Finally, Subtask E is focused on demonstrating the value in occupant behaviour modelling through applications such as improved building design and operation. In all, the Annex is currently represented by 23 countries, 57 institutions, and 90 experts. Additional experts, particularly software developers from industry, are encouraged to participate in Annex 66.
