N2 - Roof ponds (RP) can promote comfortable thermal conditions, particularly in single-storey buildings. They allow structural cooling or heating and stabilization of surface and air temperatures. When coupled to radiant panels cooled by the exposed pond, they can further improve their thermal performance. However, there is a lack of research on RPs focusing on the thermal perception of users indoors. The main objective of this study was to evaluate empirically under hot dry summer conditions the thermal perceptions of volunteer participants in an indoor environment conditioned by a system composed of radiant panels coupled to a RP. We also sought to assess the applicability of the PMV model and the passive building models of ASHRAE Standard 55 and EN-15251 under these conditions, through comparison with subjective thermal votes reported by the study participants. In a test building at Ben-Gurion University of Negev, Israel, a sample of 46 participants found a room cooled only by a RP. Thermal votes showed more agreement with the PMV and EN-15251 models than with the ASHRAE model.
