One of the most important components affecting the human thermal balance is represented by its radiative exchange with the surrounding surfaces. The projected area of the human body is an important parameter of these thermal exchanges. Unfortunately, although the anthropometric measures of people are characterized by significant differences among various populations, the experimental data currently available in the literature refers to a small group of people. Moreover, measurements are generally performed regardless of the statistical significance of the involved subjects with respect to the population to which they belong. In this study, a statistical study is introduced that is based on a large analysis of the anthropometric characteristics of the analysed population. Moreover, a new experimental procedure is applied to evaluate the projected area factor and the effective radiating area of a sample of people belonging to the population of southern Italy. The calculated projected area factors are fairly in accordance with those originally proposed by Fanger for standing people. For seated people, however, the experimental values of the present study show some differences from those of the literature. This study provided a tentative explanation for these discrepancies.
