A Simplified Simulation Model for Predicting Radiative Transfer in Long Street Canyons under High Solar Radiation Conditions

摘要: Modeling solar radiation in street canyons is crucial to understanding the availability of building facades. This article describes implementation a simulation routine, developed Matlab® computer language, which aimed at predicting access for facades located dense urban conglomerates comprising deep long canyons, under high conditions, typical southern countries Europe. Methodology primarily based on configuration factor theory, also aided by simulation, enables assess interplay between surfaces that compose so-called canyon. The results theoretical model have been cross-checked and verified on-site measurements two real case studies, streets Cadiz Seville. simplified reproduces shape curve measured values weighted errors whole do not surpass 10%, with maximum 9.32% mean 6.31%. As result, predictive takes into account direct, diffuse reflected from enclose canyon, has devised. authors consider this research provides further improvement, as well handy alternative approach, usual methods used calculation available such Sky View Factor or ray tracing.
