A methodology for estimating the intensity of the Wet Bulb Globe Temperature Index is derived from a survey of 15 representative, hot industries in three climatic regions of the continental United States. This study identifies characteristic empirical relationships between inside environmental conditions and outdoor weather conditions for hot worksites. Thus, it is possible to calculate or predict worksite Wet Bulb Globe Temperature from weather forecasts and reports from the National Weather Service or from local meteorological measurements taken at the plant site. For successful model application, it is considered necessary to first take a short-term environmental study at each worksite to characterize the nominal difference in inside-outside air temperature and to estimate the regression constants which are unique for each worksite.
