초록

Purpose: The aim of this study is to highlight the effect of the dynamic clothing insulation on indoor thermal comfort in diverse climate zones and the necessity of dynamic clothing insulation to provide comfortable indoor environment. Method: An office building was modeled through DesignBuilder, and representative climate zones were selected as tropical, marine, and cold. The dynamic clothing insulation for each climate zone was computed using the outside temperature at a specific time. For the building simulation, PMV based control applied fixed and dynamic clothing insulation was conducted. Indoor temperature and actual PMV of occupants were evaluated for the analysis of the thermal comfort. Result: In tropical and marine climates, the indoor temperature difference according to the clothing insulation values was not large (average 0.12℃ and 0.8℃, respectively) and the actual PMV was within the PMV comfort range. In cold climates, however, the difference in indoor temperature between fixed and dynamic clothing insulation was high as 0.98℃ during the heating period. In addition, when the fixed clothing insulation was applied, the actual PMV was analyzed that the discomfort periods were more frequently occurred for 58 days in heating season. Whereas, in the case of the dynamic clothing insulation, the actual PMV was within the comfortable range during the heating period. In conclusion, the influence of the dynamic clothing insulation on the indoor thermal environment in cold climate zone was emphasized. As a further studies, an estimation model accurately estimating the actual clothing insulation should be developed for providing comfort environment.
