Heat discharges from an office building in Tokyo using DOE-2

In this paper, the net heat discharge of an office building is estimated taking into account the various components of heat that flows into the building and out from the building. The results have suggested that the diurnal profiles, especially the peak heat discharge time, are significantly different from that of energy consumption by the building, while most of the past studies on the urban heat environment have assumed the heat discharges to be coincident with the energy consumption. The results also suggested that the choice of an air conditioning type plays an important role in the heat discharges. (C) 2003 Elsevier Ltd. All rights reserved.
