Evaluation of Space Thermal Comfort and Load on HVAC Equipment during Extreme Weather Days

Abstract

This paper aims to clarify the effects of extreme weather conditions on the space thermal comfort and energy consumption, which depend on the thermal characteristics of buildings and HVAC systems. Various types of extreme weather days that occur in Tokyo were picked from Expanded AMeDAS weather data for the period 1981 to 1995. Computer simulations were performed for office spaces, using 15-year Tokyo weather data to obtain the hourly changes in the PMV and the load on each of the components in a HVAC system. The type of extreme weather day that created severe conditions from the standpoint of thermal comfort and equipment load was clarified.
