Occupant-centric Building Design and Operation EBC ANNEX 79 - factsheet

As building envelopes and mechanical and electrical equipment become more efficient, the impact of occupants on building energy increases.


Meanwhile, trends in teleworking, co-working and home-sharing mean vastly different occupancy than the standard occupancy schedules.


Finally, global expectations for comfort are increasing, while a variety of new technologies may or may not succeed in meeting this demand. The convergence of these trends has necessitated a new look at how occupants are incorporated into building design and operation practice throughout the building life-cycle.


Although the field of occupant modelling emerged over four decades ago, it has surged in the past decade.


Given the number of unanswered questions about occupant comfort and behaviour and minimal penetration of advanced occupant modelling into practice, this follow-up Annex 79 - “Occupant-centric building design and operation”, explores these issues while also focusing on application and knowledge transfer to practitioners


The Annex team has just released this factsheet, providing insights into the project regarding comfort-related occupant behaviour in buildings and its impact on building energy performance.  


It is based on an open collaboration platform for data and software is being created to support the use of ‘big data’ methods and advanced occupant behaviour models.


It is further promoting the application of this knowledge in building design and operation processes by assisting decision making and by supporting practitioners.


Planned outcomes of the project are listed alongside the project objectives.
