摘要:The SARS virus began to appear and spread in North America and Southeast Asia in the early 2000′s, infecting and harming many people. In the process of examining the causes for the virus, studies on the airborne pathogen SARS virus and the way it spread were carried out mainly in the medical field. In the field of architecture, studies were done on the diffusion of air pollutants in buildings using gases such as CO2, N2O, or SF6, but research on virus diffusion was limited. There were also explanations of only the diffusion process without accurate information and discussion on virus characteristics. The aim of this study is to analyze the physical characteristics of airborne virus, consider the possibility of using a coupled analysis model and tracer gas for analyzing virus diffusion in building space and, based on reports of how the infection spread in a hospital where SARS patients were discovered, analyze infection risk using tracer gas density and also diffusion patterns according to the location and volume of supply diffusers and exhaust grilles. This paper can provide standards and logical principles for evaluating various alternatives for making decisions on horizontal ward placement, air supply and exhaust installation and volumes in large hospitals.
