Occupant health can be strongly influenced by indoor air quality due to time spent indoors (90%). Such quality can be impacted by indoor atmospheric pollutants present. Therefore, demand-controlled ventilation can be a key to improving indoor air quality. The main aim herein is to scrutinize measurement results of several air pollutants possibly existing inside university building including CO₂, volatile organic compounds, formaldehyde, benzene, CO, PM_2.5 during three measurement campaigns (March 2017, May 2017 and October–November 2017) via a smart sensor specially developed. Likewise, some factors to assess comfort such as relative humidity and ambient air temperature were examined. CO₂ were found to be higher during periods of occupancy with concentrations exceeding 2000 ppm during the first campaign. As a result, the occupants felt uncomfortable. Analysis of the survey results regarding the indoor air temperature showed that 80% of occupants found the temperature during school periods to be uncomfortable. In addition, the ‘ICONE’ air containment index was extremely high, indicating that the deemed class was confined during occupancy. The outcomes will be useful for the development of future indoor air quality guidelines, ventilation design and occupant satisfaction in buildings.

由于在室内花费的时间（90％），室内空气质量会严重影响乘员的健康。此类质量可能会受到存在的室内大气污染物的影响。因此，按需控制的通风可能是改善室内空气质量的关键。本文的主要目的是在三个测量活动（2017年3月，2017年5月和2017年10月至2017年11月）中仔细检查大学大楼内可能存在的几种空气污染物的测量结果，包括CO ₂，挥发性有机化合物，甲醛，苯，CO和PM _2.5。通过专门开发的智能传感器。同样，检查了一些评估舒适性的因素，例如相对湿度和周围空气温度。一氧化碳₂被发现在居住期间较高，在第一次竞选期间的浓度超过2000 ppm。结果，乘员感到不舒服。对有关室内空气温度的调查结果的分析表明，有80％的居住者认为在上​​学期间的温度不舒服。此外，“ ICONE”的空气密闭指数极高，表明所认为的舱位在居住期间受到限制。这些结果将有助于制定未来的室内空气质量准则，通风设计以及建筑物中的居住者满意度。
