Carbon dioxide (CO2 ) sensors that provide a visual indication were installed in classrooms during normal school operation. During 2-week periods, teachers and students were instructed to open the windows in response to the visual CO2 feedb...
The modifying effect of the building envelope on population exposure to PM2.5 from outdoor sources [0.03%]
建筑围护结构对户外PM2.5人群暴露影响的模拟研究
J Taylor,C Shrubsole,M Davies et al.
J Taylor et al.
A number of studies have estimated population exposure to PM2.5 by examining modeled or measured outdoor PM2.5 levels. However, few have taken into account the mediating effects of building characteristics on the ingress of PM2.5 from outdo...
Assessment of ultrafine particles in Portuguese preschools: levels and exposure doses [0.03%]
葡萄牙学前教育机构中超细颗粒物的评估：水平与暴露剂量
