A NEW METHOD TO DESCRIBE THE COMBINED EFFECT OF DRAUGHT AND RADIANT THERMAL ASYMMETRY ON HUMAN WORK PERFORMANCE

Human resources are the most important elements of economic units; thus, the efficiency of human work is of crucial importance. Work efficiency can be achieved only in an environment offering optimal thermal comfort. The present study makes use of human subject experiments in order to investigate the joint effect of draughts and warm ceilings on work performance. During the experiments, 10 thermal environments with 5 radiant thermal asymmetries and 2 draught rates were investigated. The most important outcome of the research is the presentation of the combined effect of a draught and a warm ceiling on work performance.
