As one of the typical architectural features in hot and humid regions, the lift-up design can provide effective shading and sufficient pedestrian-level ventilation, which is favorable for building functions that require natural ventilation, such as the canteen. However, it is unknown whether the thermal environment and air quality of lift-up areas meets the indoor environment requirements along with other building features, like glazing. Thus, this paper presents environmental evaluation results of thermal sensation and air quality using a lift-up school canteen with glazing as the case study. The following two questions are answered in this paper: (1) whether the lift-up area alone meets environmental requirements for school canteen in the hot and humid region; (2) whether the thermal comfort and air quality are improved or worsened in the lift-up area when glazing is used on building façade. The analysis results revealed that lift-up canteens have good thermal comfort and air quality in hot and humid areas, but when glazing was added to the lift-up canteen facade, the thermal comfort and air quality were seriously reduced, in which the reduction of wind speed is the main factor. This paper can serve as a scientific basis for architects in sustainable building design.

升降式食堂玻璃对室内环境的影响

作为湿热地区的典型建筑特征之一，上拉式设计可以提供有效的遮阳和充足的人行通风，有利于食堂等需要自然通风的建筑功能。然而，尚不清楚举升区域的热环境和空气质量以及玻璃等其他建筑特征是否满足室内环境要求。因此，本文以学校玻璃窗升降食堂为例，介绍热感和空气质量的环境评价结​​果。本文主要回答以下两个问题：（1）仅举升面积是否满足湿热地区学校食堂的环境要求； (2)建筑外墙采用玻璃后，抬升区域的热舒适性和空气质量是否改善或恶化。分析结果表明，在湿热地区，升降式食堂具有良好的热舒适性和空气质量，但在升降式食堂立面加装玻璃后，其热舒适性和空气质量严重下降，其中风速是主要因素。本文可为建筑师进行可持续建筑设计提供科学依据。
