The ability to accurately determine localized building occupancy in real time enables several compelling applications, including intelligent control of building systems to minimize energy use and real-time building visualization. Having equipped an office workspace with a heterogeneous sensor array, our goal was to use the sensors in tandem to produce a(More)
Simulation-based design can enable a number of advanced architectural and engineering applications such as energy modeling, occupant behavior prediction, or structural integrity analysis. To help make simulation-based design practical, scalability in terms of data and computation is needed. By using a Model-Driven Architecture (MDA) approach together with(More)
Building performance simulation promises to reduce the future impact of buildings on the environment by helping architects predict the energy demand associated with different design options. We present a new method for simulating occupant behavior in buildings, a key phase in the prediction of energy use. Our method first inputs the recorded activities of(More)
Presynaptic nerve terminals are located at the ends of nerve cells; a signal propagating through a nerve cell reaches one of these compartments before being transmitted to an adjacent nerve cell. A tethered particle system (TPS) is a type of impulse-based model recently developed for the simulation of deformable biological structures. In a TPS, collisions(More)
Accurate building occupancy information can be beneficial in minimizing energy use by improving the intelligence of a Building Automation System (BAS) and helping designers predict the effect of different design options on occupant behavior. However, current occupancy measurements are quite inaccurate due to limitations in sensing technology and the(More)
This work introduces personas, descriptions of fictional individuals used in the field of human-computer interaction , into the simulation of building performance. The ultimate goal is to reduce the impact of buildings on the environment by helping architects predict the energy demand associated with different design options. As energy consumption patterns(More)
This paper explores the design, coupling, and application of algorithms relying on grid-based or voxel-based representations of buildings. Such algorithms may encourage the adoption of building performance simulation in design practice by avoiding the time-consuming and somewhat arbitrary process of manually partitioning a building's interior into(More)
The building performance simulation community applies theory from several different fields to develop models for heat transfer, light propagation, human behavior , and other domains. To integrate these models, we propose the adoption of general modeling conventions from the less familiar field of modeling and simulation theory. The conventions we explore(More)
