Occupant behaviors change the state of energy consuming systems such as window shading, thermostat setpoints, and lighting levels, on an irregular basis not currently captured in pre-defined schedules or programmed system state triggers (e.g., dynamic daylight dimming controls) commonly used in current energy simulation data models. Also, occupants move around in a building or may leave a building for short periods such as during lunch breaks, unlike fixed building features like windows and zones, in ways that again are not captured in pre-defined occupancy schedules. The proposed research does not focus on the analysis of underlying behavioral theories responsible for occupants’ behavior, rather the emphasis is on the behavioral actions and interactions data required for energy simulation. The intent of the proposed research project is to directly address the integration of occupant behavior and energy simulation data to bring these building information models together. The scope is limited to enhancements in BIM data schemas and future work may include improvements in energy modeling software. The objectives are as follows:
- Review existing occupant behavior and energy simulation data models.
- Explore how these disparate data models might best be integrated into a common data model.
- Document the integration of common data models.
- Provide an example dataset merging into the common data model, with written user guidance.
