Test Study About PM2.5 Penetrations Through Building Envelope
Outdoor particulates may penetrate into indoor environments through building envelope even if doors and windows are fully closed, which causes increase of indoor suspending particle concentration and can constitute a potential health hazard. Particulate matter mass concentrations were measured indoors and outdoors at a female dormitory at the end of winter in Harbin, a severe cold city in China. The paper aims at on-site test research of PM2.5 penetration characteristics through students’ dormitory building envelope, by observing indoor–outdoor PM2.5 concentrations, the indoor–outdoor ratios were obtained, and then the dynamic model was utilized to calculate the average penetration efficiency, the average particle deposition rate and the average infiltration factor. In this study, we utilize methods for determining penetration efficiencies for particles and investigate the relationship between penetration, deposition and the concentrations of airborne particles indoors and outdoors. The case study may provide practical reference for the overall particulate penetration research in civil buildings in China.
