Abstract (EN): Hospitals, by the nature of their function, are high energy consumers and thus buildings where the potential of energy saving is high. In hospitals built prior to the implemented European directives on energy performance of buildings the compliance with the current energy standards is difficult to achieve. This work performs a holistic experimental and numerical study to assess the thermal behavior and energy retrofitting potential of medical offices of a hospital building prior to these directives. The nursing school Francisco Gentil building of the Portuguese Oncology Institute in Lisbon, was chosen as case study. For thermal behaviour assessment, field monitoring of two typical medical offices, in opposite facades, was carried out in terms of temperatures, heat flows and irradiances in the heating and cooling seasons. Thermal comfort and U-values evaluation and a frequency-domain approach were complementary analyses performed. Finally, an experimentally calibrated building energy simulation was performed to obtain solutions that enhance the energy performance of the offices. By implementing as retrofit solutions double reflective glass in windows, 6 cm of extruded polystyrene on the exterior walls and 7 cm on the roof, energy savings up to 53% can be achieved in the medical offices. © 2021 Elsevier Ltd
