IEA Annex 79 Expert Meeting & International Symposium on Occupant Behaviour

Share this Post:

Occupant Behaviour 2020 (OB-20) is the 5th International Symposium focusing on designing and operating buildings with an occupant focus, and the underlying comfort, behavior, and energy considerations. OB-20 (Apr 21st) aims to stimulate discussions and debate and to encourage contributions to IEA EBC Annex 79 “Occupant behavior-centric building design and operation”. Presenters from broad backgrounds (engineering, architecture, psychology, sociology, marketing, etc.; researchers or practitioners) are encouraged to attend and/or present. 


A two-day Annex 79 meeting (Apr 22nd and Apr 23rd) follows OB-20, with all symposium participants welcome to attend.


Important information – OB-20 & Annex 79 to be held online


The IEA Secretariat have given notice that all face-to-face meetings before June are to be changed to an online format, due to the perceived risks of coronavirus. The University of Southampton plan to host the virtual events on the dates and times currently scheduled, and hope to allow these to take place no differently than if they were in-person (with plenaries, break-out sessions, etc.).


More information will be available in the coming days and weeks as alternative arrangements are made (use the link below to view updates).  If you have any questions, please feel free to get in touch. Otherwise, we look forward to seeing you online!

The EBC Research Programme


Approximately one third of primary energy is consumed in non-industrial buildings such as dwellings, offices, hospitals, and schools where it is utilised for the heating and cooling, lighting and operation of appliances. In terms of the total energy end-use, this consumption is comparable to that used in the entire transport sector. Hence the building sector represents a major contribution to fossil fuel use and related carbon dioxide emissions. Following uncertainties in energy supply and concern over the risk of global warming, many countries have now introduced target values for reduced energy use in buildings. Overall, these are aimed at reducing energy consumption by between 5% and 30%. To achieve such a target, international cooperation, in which research activities and knowledge can be shared, is seen as an essential activity.


The IEA (International Energy Agency) Energy in Buildings and Community (EBC) Programme carries out research and development activities toward near-zero energy and carbon emissions in the built environment. These joint research projects are directed at energy saving technologies and activities that support technology application in practice. Results are also used in the formulation of international and national energy conservation policies and standards.


The EBC Research Strategy


The IEA 'Energy in Buildings and Communities' Technology Collaboration Programme carries out research and development activities toward near-zero energy and carbon emissions in the built environment. The R&D activities focus on the integration of energy-efficient and sustainable technologies into healthy buildings and communities. EBC's mission is to support the acceleration of the transformation of the built environment towards more energy efficient and sustainable buildings and communities, by the development and dissemination of knowledge, technologies and processes and other solutions through international collaborative research and open innovation.

Many current and former researchers from EBC projects are often directly involved in formulating standards, regulations and codes and will use the knowledge gained in their work for EBC to inform and improve them. This indirect form of deployment can be one by which the Programme has a strong although less obvious impact.


EBC projects and activities have produced long-lasting decision-making tools and integrated systems technologies. Outcomes from the Programme are publicised through many seminars and conferences.


The R&D strategies are derived from research drivers, national programmes within IEA countries, and the IEA FUTURE BUILDINGS FORUM Think Tank Workshop, held in April 2013. The R&D strategies apply to residential, commercial, office buildings and community systems.


EBC is one out of eight Building Related Technology Collaboration Programmes (BRTCPs) within the IEA's energy technology network.


The EBC Research Projects (Annexes)


The EBC Research Programme is mainly undertaken through a series of research projects, so-called 'Annexes'. Typically each Annex has a life span of 3-4 years, although extensions are possible if a continuing need for the activity is identified. Clear goals are set for each activity so that well defined products are generated. Publications are available for several ongoing and most completed annexes.
