Non-enclosed atriums, which give unobstructed access to the surrounding area, are gradually becoming common in modern shopping malls. The environmental problems they cause (e.g., vertical thermal stratification and overheating) are thus affecting adjacent occupied zones more often. This study focuses on the thermal environment of occupied zones adj...

With increasing urbanisation, the fraction of built-up areas and human activities increase, deteriorating the urban thermal environment and air quality. To improve the urban environment, wind corridors have attracted much research attention in recent years. In this study, a sky-view factor (SVF)-based method is proposed and verified for the potenti...

The thermal conditions of a non-enclosed atrium and the adjacent zones are significantly related. We propose an extended Block model to predict their vertical temperature distribution by incorporating mass and heat transfer processes (horizontal convection and descending flow deflection). Regarding the air flowing horizontally from the adjacent zon...

Low-temperature air infiltration and vertical thermal stratification lead to an unsatisfied bottom-occupied environment of the atrium and increase the space heating load in winter. An integrated prediction model was proposed regarding the interaction between thermal stratification and air infiltration. It includes the extended Block model for predi...

High indoor air quality is crucial for the health of human beings. The purpose of this work is to analyze the synergistic effect of particulate matter 2.5 (PM2.5) and carbon dioxide (CO2) concentration on occupant satisfaction and work productivity. This study carried out a real-scale experiments in a meeting room with exposures of up to one hour....
