High-rise residential developments are rapidly increasing in urban areas. Smaller residential units in this high rise bring a reduction in windows, resulting in poor indoor air ventilation. In addition, materials used in interiors can emit volatile organic compounds (VOCs), which can significantly affect human health. Since people spend 90% of their time indoors, an evaluation of indoor air quality is especially important for high-rise residential buildings with an analysis of determining factors. This study aims to measure the concentrations of VOCs, formaldehyde, and particulate matter (PM_2.5 and PM₁₀) in 9 high-rise residential buildings in Bangkok by using the accidental sampling method (n = 252) and to investigate possible important determining factors. The results show that the average concentrations of VOCs, formaldehyde, PM_2.5, and PM₁₀ in 9 high-rise residential buildings were at good to moderate levels in the indoor air quality index (IAQI) and that high pollutant concentrations were rarely found except in new constructions. Moreover, it was found that the age of buildings shows strong correlations with all pollutants (p value < 0.0001). Old buildings showed significantly lower pollutant concentrations than new and under-construction buildings at a 95% confidence level. The findings from this investigation can be used as part of sustainable well-being design guidelines for future high-rise residential developments.

市区的高层住宅发展迅速。高层住宅中的小型住宅单位减少了窗户的数量，导致室内空气流通不畅。此外，用于室内的材料会释放出挥发性有机化合物（VOC），这会严重影响人体健康。由于人们将其90％的时间都花在室内，因此对高层住宅建筑物进行室内空气质量评估并分析决定因素尤其重要。这项研究旨在使用意外取样方法（n）来测量曼谷9座高层住宅建筑物中VOC，甲醛和颗粒物（PM _2.5和PM ₁₀）的浓度。= 252）并调查可能的重要决定因素。结果表明，在9座高层住宅建筑中，VOCs，甲醛，PM _2.5和PM ₁₀的平均浓度在室内空气质量指数（IAQI）中处于中度至中等水平，除新建筑。此外，还发现建筑物的年龄与所有污染物都有很强的相关性（p值<0.0001）。在95％的置信度下，旧建筑物的污染物浓度明显低于新建筑物和在建建筑物。这项调查的结果可以用作未来高层住宅开发的可持续福祉设计准则的一部分。
