The purpose of this study was to analyze the need of adopting thermal environment code meeting comfort zone in public buildings. The thermal environment in public buildings was analyzed for this study. Furthermore, occupant's thermal comfort and work efficiency were measured through qualitative and quantitative evaluation before and after the implementation of the system. In addition, the usage of individual heating and cooling appliances were analyzed for the additional increase in energy consumption. As a result, the study showed that occupants' thermal comfort and work efficiency were declined after the implementation of the system. Due to reduced thermal comfort, the use of individual heating and cooling appliances increases. Therefore, it needs to improve thermal environment code in public buildings.

For a general office building having a center core, the distinction between the outer wall and the compartment should be clear, and it should be set at a stack effect pressure distribution acting on the respective compartment by a relative area ratio of the respective leak compartment. In the case of office buildings with an independent core for core there, some blocks of shares and exterior pressure distribution in buildings and office buildings typically have different characteristics. Therefore, if the stack effect reduction measures, designed on the basis of a general office building are applied to a stand-alone building, the core of the building should reflect the unique pressure distribution characteristics. This study, performed as part of the object corresponding to the flat plan of the building in the diversification trend, analyzed the stack effect that actually occurs in an office building having the properties intended for stand-core construction, and thus on the basis of and tested by the method of using a conventional stack effect reduction measures. Reviewed in the study, an independent cored office building that does not have the air flow path through the specific space with respect to the center core type office building has a feature, and the variation in characteristics of the pressure distribution inside the building according to this air flow path stack effect was reduced by a variety of measures that should be applied to determine the application.
