The objective of this study is to develop the operation model of the double-skin facade for energy conservation and user comfort. This study proposes development process of the operation model in three steps. A case study is used to investigate the feasibility of the process. The G building in Kungkido is chosen. The main contents of this study are as follows. 1) The operation objectives and standards are established. And the operation factors classified according to the objectives and standards. 2) Correlation of the operation factors are clarified. And Individual models. The operation model is essential to building which has the double-skin facade and logical operation would be improved by this model. For the practical application of this operation model, it will be needed to connect the building management system.

The objective of this study is to analyze the applicability of the Radiant Floor Cooling integrated with dehumidification system through field experiments. The experiments are performed to evaluate the thermal environments and system operations according to varying the load conditions which is able to happen to field and show the available cooling source for radiant cooling system. The results of this study are as follows. 1) The radian floor cooling integrated with dehumidification system shows stable thermal environments and system operations in view of these aspects : control offset room air temperature, preventing condensation, stayed within the comfort range. 2) A supplementary cooling device can reduce the cooling time at the beginning because it can utilize radiant and convective cooling method. 3) The result of analyzing the change of the cooling water temperature in the actual apartment building shows that the system can operate according to the planning value.

The objective of this study is to analyze the performance evaluation of the Radiant Floor Cooling and the dehumidification system included in the integrated system may be utilized as a supplementary cooling device through field experiments. The experiments are performed to evaluate the performance of the radiant floor cooling and confirm the possibility of continuous cooling through the actual field experiments, moreover, analyze specific characters of the radiant floor cooling system according to varying the load conditions which is able to happen to field. Experiment results show that the permissible ambient temperature range was determined by cooling load calculations, and the cooling capacity was calculated from steady-state heat transfer equations. Under these conditions, experiments were performed for an actual apartment building assuming two occupants. During 80% of the cooling period, radiant floor cooling provides sufficient and continuous cooling. The results of analyzing the indoor thermal environment in the actual apartment building show that the set room air temperature is maintained while the floor surface temperature, vertical temperature distribution and PMV remain within the comfort range.
