Lessons Learned from Applications of Occupant Behavior Modeling

Clinton Andrews, Jennifer Senick, Rutgers University, Rutgers Center for Green Building

Building occupant behavior modeling is beginning to enjoy wider application around the world. This presentation illustrates the range and types of applications, offers a framework for classifying types of applications, and considers which modeling approaches (deterministic, Markovian, agent-based, and others) are most appropriate for which contexts. Summaries of thirty-two case studies we gathered for IEA Annex 66 from North America, Europe, and Asia show which modeling strategy each adopts, given its context. Essential elements of the framework answer familiar questions: who, what, why, when, and where? In determining which model is most fit for each context, three dimensions emerge as being particularly important. These are the stakeholder and their problem (Who? Why?); the building type, services and provisions (What?); and the process stage and relevant tools (When?). The amount of influence that occupant behavior has on building energy consumption varies systematically, and the degree of precision needed about it likewise varies significantly over the phases of a building’s life.
