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)
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)
A new model is proposed for the simulation of deformable biological structures such as proteins, membranes, tissues, and organs. The idea involves the use of discrete-event simulation to track the motion of large numbers of colliding particles. If two approaching particles reach an inner limiting distance, they collide, rebound outwards, and may become(More)
The application of the DEVS formalism to spatial simulations of biological systems is motivated by a need to keep software manageable, even when faced with complex models that may combine algorithms for potential fields, fluid dynamics, the interaction of proteins, or the reaction and diffusion of chemicals. We demonstrate DEVS-based design by applying the(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)
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)
In this paper we apply the principles of Exploratory Sequential Data Analysis (ESDA) to simulation results analysis. We replicate a resource consumption simulation of occupants in a building and analyze the results using an open-source ESDA tool called UberTagger previously only used in the human-computer interaction (HCI) domain. We demonstrate 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)
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)
