Abstract

This study examines the relationship between individual thermal satisfaction and worker performance. Field measurements and a questionnaire survey were conducted within an organization participating in the COOL BIZ energy conservation campaign. A subjective experiment was also conducted in a climate chamber with eleven Japanese male subjects, testing five scenarios combining operative temperature (25.5°C and 28.5°C), clothing (with and without suits), and cooling items (desk fan, air-conditioned shirt, mesh office chair). From the individual analysis, actual air temperature in the COOL BIZ office was poorly correlated with self-estimated performance, whereas perceived thermal satisfaction correlated well with self-estimated performance (R2=0.944, p<0.001). The results of the subjective experiment indicate that performance during simulated office work (i.e. multiplication and proof reading tasks) increased with greater individual thermal satisfaction (R2=0.403 and 0.464, p<0.001). The finding that perceived thermal satisfaction of occupants is reflected in objective measurement of office work performance has practical implications for the evaluation of thermal satisfaction in real offices as a means to boost workplace productivity.
