Recently, there has been an ongoing effort to quantify the effect of occupants’ behavior and preferences – e.g.
occupancy patterns, window opening/closing, and control of shading devices and artificial lights, as well as
preferred indoor temperatures – in the performance of buildings. As an outcome, various stochastic occupant
behavior (OB) models have been developed. These models are able to capture more accurately occupants’
actions in buildings – compared to referential values defined in various standards – and when coupled with a
performance simulation model of the building in a co‐simulation setup can assist towards increasing simulation accuracy.
A collection of such models has been implemented as a Functional Mock‐up Unit (FMU) at Fraunhofer–
Institute for Building Physics, and tested successfully in simulation environment. This setup should be expanded
utilizing real‐building data in this work.
The first objective of this master work is to test the following hypothesis: “OB models can reduce the gap between
simulated and real performance of a building.” The second objective is to find out which behavior model(s) from the existing library lead to more accurate simulation models and why.
We will provide a building simulation model (in EnergyPlus or Trnsys) of a real building and real operation data,
as well as the library of OB models for testing.
