A substantially revised version of the original bioclimatic chart as developed in the 1950s was presented. The original chart was a cartesian plot of temperature versus humidity which has been used by architects as the basis for designing buildings in which natural forces are used to maintain a comfortable environment. The new chart included recent experimental research results. A thermophysiological model was developed to simulate the thermal behavior and resulting comfort sensation on an individual at two clothing levels and a rate of activity which is typical of office work, house work, or shopping. The criteria for the boundaries of the comfort zone were based on ASHRAE standards. The revisions have been obtained from simulation of an assumed building occupant using a two node mathematical model of human thermoregulatory systems. The model considered the person as two concentric thermal compartments representing the skin and the core of the body. While the still air comfort zone resembled the original one fairly closely, the air motion and radiation lines were markedly different using this newer approach.
