Indoor environmental evaluation of traditional Chinese medicine clinic – taking the treatment space as an example

Currently, there are no targeted standards and norms for Chinese medicine clinic diagnosis and treatment space. This study conducted field research in nine Chinese medicine clinics located in Hangzhou. The field research included the measurement of physical environment data in addition to the patients' subjective evaluation of the factors of the physical environment and design within the clinics, followed by statistical data analysis. The results show that the order of importance of physical environment factors in the diagnosis and treatment space was as follows: air quality > sound pressure level > humidity > temperature and the order of importance of the design factors were as follows: access route > supporting facilities > overall style > spatial scale > barrier-free design > cultural atmosphere and the order of importance of the spatial scale factors were as follows: area > the number of beds > window-to-wall ratio > floor height. The study presents the reference values of the physical environment parameters and spatial scale of the Chinese medicine clinics and the importance ranking of each factor.
