Current thermal comfort standards are mainly intended for the assessment of steady-state conditions. This report deals with human comfort under transient conditions, as found in passive solar buildings. Experiments were performed to investigate the physiological and subjective responses to temperature transients using twin climate chambers. It was observed that in some circumstances the present thermal comfort standards (ISO 7730 and ASHRAE 55-81) underestimate the thermal impact of operative temperature transients on man. A simple model for predicting the thermal sensation caused by temperature down-steps is proposed. Field experiments on the effects of temporal and spatial transients are described.
