During the course of the SCATs project, thermal comfort data was collected from a number of buildings throughout Europe. 25 buildings were surveyed across the UK, France, Sweden, Greece and Portugal by members of the SCATs consortium. This data formed 3 distinct databases of thermal comfort (transverse, longitudinal and background data) which has potential for further R&D. The data collected included indoor and outdoor temperatures, thermal comfort responses, occupant use of controls, demographic data of building occupants, clothing insulation and metabolic rate. Over 30,000 responses are available for analysis on the databases. The databases will be of use to researchers in the built environment as they contain information on occupant responses to a variety of environmental stimuli, as well as general reactions to their workplaces.
