title Enhanced Boundary Representation: A Lingua Franca for Computer-Based Building Performance Simulation?
source ACADIA Quarterly, vol. 19, no. 4, pp. 12-14
summary With the realistic visual representation of buildings on the computer having reached maturity, the emphasis has now shifted to the performance simulation of buildings on the computer. The challenge of performance simulation in computer-based models of buildings lies in the integration of various simulation techniques that require different kinds of building representations. Traditional simulation techniques for luminous, acoustic and thermal environments require different building representations. Thepaper proposes that an enhanced boundary representation is a viable, common building representation format for performance simulation of illumination levels, acoustical parameters and thermal comfort, thereby providing a building representation format for multi-domain performancesimulation on the computer. Simulation techniques that have been developed for radiosity-based modeling of illumination in buildings, radiation-based modeling of sound propagation in spatial enclosures, and the modeling of thermal comfort based on mean radiant temperatures, point to a convergence of techniques. These techniques can all work based on an enhanced boundary or surface representation of buildings. The paper suggests that an enhanced boundary representation format, and integrated performance simulation techniques based on radiation, can together serve as a core model for developers of computer-aided design analysis systems.
