Digital Simulation for Buildings' Outdoor Thermal Comfort in Urban Neighborhoods

Buildings' outdoor thermal comfort influences environment quality and human behavior in urban neighborhoods. The Universal Thermal Climate Index (UTCI) has been broadly applied to the study of buildings' outdoor thermal comfort in urban areas. However, complex environmental conditions in climate-sensitive urban areas can make UTCI assessment complicated and ineffective. This paper introduces digital techniques into buildings' outdoor thermal comfort analysis for the improvement of the urban habitant environment. A digital simulation system is generated to facilitate the analysis procedure for buildings' outdoor thermal comfort assessment in urban neighborhoods. The analysis addresses the research question: "Can digital simulation techniques provide a modeling system to assess buildings' outdoor thermal comfort continuously and effectively? " Methods include a case study of neighborhoods in Beijing, qualitative and quantitative analysis based on digital processes, and parametric modeling. The results indicate that digital simulation techniques and tools have the capability to support the analysis of buildings' outdoor thermal comfort by providing three-dimensional models, algorithm-based analysis, and visual simulation. The findings include a critique of digital simulation as applied to architecture study and insights on potentially improving buildings' outdoor thermal comfort through human-computer interactions.
