随着特大城市医院规模的不断扩大，医院街布局对医院效率和稳定性的影响越来越大。本研究采用客观现场测量和主观问卷调查相结合的方法，对半封闭医院街道及其相邻门诊候诊区进行室内环境质量调查。结果表明：医院街道存在过热过湿环境，湿度比为17.7 ~ 18.6 g/kg；因此，居住者对热环境的不满意率超过了50%。医院街道空气与门诊候诊区的空气混合导致门诊候诊区的室内温度为27-29℃，超过了26℃的标准阈值。医院街道的室内空气质量（CO2、总挥发性有机化合物（TVOC）和PM2.5浓度）良好，符合中国现行标准。然而，透过透明乙烯-四氟乙烯（ETFE）膜屋顶的点眩光和医院街道照明不均匀造成视觉不适。ETFE膜屋顶在降雨时的振动导致医院街道的噪音水平为79.5 dB(A)，门诊候诊室的噪音水平为70 dB(A)，严重降低了声学舒适度，导致居住者不满意率为60%。因此，本研究提供了医院街道和门诊候诊区室内环境质量的客观和主观数据。
With hospitals in megacities becoming larger, the hospital-street layout has an increasingly larger impact on the efficiency and stability of a hospital. In this study, the indoor-environment quality of a semi-closed hospital street and the adjacent outpatient waiting areas were investigated using objective on-site measurements and subjective questionnaire-based surveys. The results revealed that the hospital street had an over-heated and over-humid environment, with a humidity ratio of 17.7–18.6 g/kg. Consequently, the occupant-dissatisfaction rate in terms of the thermal environment exceeded 50%. The blending of air from the hospital street with that from the outpatient waiting areas led to an indoor air temperature of 27–29 °C in the latter, which exceeds the standard threshold of 26 °C. The indoor air quality (in terms of CO2, total volatile organic compounds (TVOC), and PM2.5 concentration) of the hospital street was good, ensuring compliance with existing Chinese standards. However, spot glare through the transparent ethylene-tetra-fluoro-ethylene (ETFE) membrane roof and uneven illumination in the hospital street caused visual discomfort. Vibration of the ETFE membrane roof during rainfall led to noise levels of 79.5 dB(A) in the hospital street and 70 dB(A) in the outpatient waiting rooms, severely reducing acoustic comfort and resulting in an occupant-dissatisfaction rate of 60%. Thus, this study provides data, both objective and subjective, of the indoor-environment quality in both hospital streets and outpatient waiting areas.
