摘要:Introduction. Nowadays several rating systems exist for the evaluation of the sustain- ability of buildings, but often their focus is limited to environmental and efficiency aspects. Hospitals are complex constructions in which many variables affect hospital processes. Therefore, a research group has developed a tool for the evaluation of sustain- ability in healthcare facilities. Methodology. The paper analyses social sustainability issues through a tool which evalu- ates users' perception from a the quality and well-being perspective. It presents a hierar- chical structure composed of a criteria and indicators system which is organised through a weighing system calculated by using the Analytic Network Process. Results and discussion. The output is the definition of a tool which evaluates how Humanisation, Comfort and Distribution criteria can affect the social sustainability of a building. Conclusion. Starting from its application, it is evident that the instrument enables the improvement of healthcare facilities through several design and organisational sugges- tions for achieving healing and sustainable architectures.
