JAUE2018-026 Estimation of a Cooling Energy Demand for Acceptable Thermal Comfortof Korean Slice Room based on Field Study

Abstract

Global warming and climate change are among the most important issues worldwide. In this situation, slice rooms, which are inexpensive residential spaces for the poor, are exposed directly to the heat because of the lack of room cooling systems. However, South Korean energy welfare policies focus on winter only, so that most of the indwellers of slice rooms are experiencing thermal diseases due to persistent hear waves. Therefore, cooling energy welfare policies for them are required and studies of cooling energy demand that can be used 
as the basic data are necessary. This study aims to estimate cooling energy demand for acceptable thermal comfort of slice rooms. Case models of the slice rooms in Daegu were selected based on the data collected through a field study and the cooling energy demand, consumption, and cooling costs were derived through a building energy simulation program. Based on the results of analysis, the room temperatures of the slice rooms in summer can be adjusted to 28℃, which is judged to be an acceptable thermal comfort level, at a cost of 1% of the minimum cost of living.
