本研究采用客观物理测量和主观问卷调查相结合的方法，对我国住院建筑的室内环境质量进行了调查。夏季住院楼的相对湿度达到65%-75%，导致室内表面经常出现微生物生长。通过CO2浓度衰减法测量的采样病房的平均室外换气率为1.1 h-1，比标准阈值低45%。超过99%的功能空间中的CO2浓度低于1000 ppm的阈值。然而，由于医疗活动的特点，空气新鲜度的不满意率高于25%。由于新风量不足，新风系统送风湿度过高，导致住院楼通风能力不足，环境过湿。从室内TVOC和PM2.5浓度的角度来看，在住院建筑中实现了好客的室内空气品质。在护士单位，公共区域，如病人走廊和护士站的照明水平不足。病房和护士站的平均噪声声级（A）分别为50.7和61.6dB，超过国家标准。根据主观调查，病人和来访者对夏季整体IEQ的不满意率分别为7.9%和10.4%，而工作人员的不满意率为34.8%。统计分析显示，病人对IEQ的满意度高于来访者和工作人员。
In this research, objective physical measurements and subjective questionnaire surveys are used to investigate the indoor environment quality of Chinese inpatient buildings. The relative humidity in the inpatient buildings reaches 65%–75% during summer, resulting in the regular appearance of microbial growth on indoor surfaces. The average outdoor air change rate measured through the CO2concentration decay method in the sampled inpatient rooms is 1.1 h−1, which is 45% below the standard threshold. The CO2concentration in over 99% of the functional spaces is below the threshold of 1000 ppm. However, the dissatisfaction rate of the air freshness is higher than 25%, owing to the characteristics of healthcare activities. Insufficient fresh air volume and high supply air humidity ratio of the outdoor air system result in the inadequate dehumidification capacity and the over-humid environment in the inpatient buildings. From the perspective of indoor TVOC and PM2.5 concentration, a hospitable IAQ is achieved in the inpatient buildings. In the nurse unit, the illumination levels in public areas, such as patient corridors and nurse stations, are inadequate. The average noise levels (A) in the inpatient rooms and nurse stations are 50.7 and 61.6 dB, respectively, which exceeds the Chinese standard. According to the subjective survey, the dissatisfaction rates of overall IEQ in the summer for patients and visitors are 7.9% and 10.4%, respectively, while for staff it is 34.8%. Statistical analysis reveals that the satisfaction levels of the patient with the IEQ are higher than that of the visitor and staff.
