Human body exergy consumption in the thermal environment of shelter gymnasium in winter

Abstract

This study attempts to evaluate the thermal stress in the winter shelter gymnasium in terms of human body exergy balance analysis. The human body's exergy consumption rate was quantitatively analysed, revealing that the total human exergy consumption differs depending on the difference in heat insulation performance of the evacuation gymnasium. Integrated exergy consumption after 30 days is 15.7 MJ/m2 for an 'existing outer skin with no heating', 14.4 MJ/m2 for an 'existing outer skin with radiant heating', and 12.5 MJ/m2 for a 'modified outer shell with no heating' It decreased to 9.6 MJ/m2 in the 'rehabilitating envelope with radiant heating'. In the case of existing hulls, accumulation of thermal stress was found to be greater than in the case of renovation hulls.
