Abstract
This work presents a study of a physiotherapy center located in the southern area of Bolzano, discussing its indoor visual comfort conditions, energy consumption for artificial lighting and daylight exploitation. Specifically, three South-West oriented physiotherapy cabins with large glazed façades were analyzed, using both measurements, in-situ subjective surveys, and simulations. First, illuminance measurements and visual comfort questionnaire responses were analyzed to detect possible issues related to the lighting system and the visual environment in the therapy cabins. Daysim models were then developed, compared with empirical data and deployed to assess advantages and drawbacks of the internal double layer roller shades. Finally, an alternative external venetian blinds system was proposed and studied.
