Die geskiedenis van die ontwikkeling van die termiese gemaksone-konsep

Abstract

The impact of the local climate on the indoor climate of buildings and in­door thermal comfort has long been understood, intuitively as well as qualitatively. With the advent of heating and cooling technologies, it became important to define a comfort target that was initially assumed to be a dry ball air temperature. As a result of (conflicting) climate chamber and field studies this point has to be broadened to a thermal comfort zone, valid for a statistical population. The thermal comfort zone had to be further described by dimensions as contained in the bioclimatic/psychrometric charts. This is reflected in the present ISO standard. An improvement on this is the adaptive model that defines thermal comfort as the resultant of physiological reactions as well as expectations built on previous experience. An improvement on the latter accepts the fact that a person plays an important role in creating thermal preferences. Finally it appears that a climate for thermal comfort is not the same as one for productivity.
