다국어 초록 (Multilingual Abstract)

In this study, green remodeling was performed on an existing public building. Energy performance of the modeled building was evaluated through simulations. The ECO2 program, a tool for evaluating the rating certification system for building energy efficiency, was used. Green remodeling reinforced the insulation of the exterior walls and roofs of the buildings and replaced high-efficiency windows and doors. Further, a passive technique was applied to enhance airtight performance. The energy performance before and after green remodeling was comparatively analyzed using various simulations. The results indicated that both energy demand and energy consumption significantly decreased for heating energy but marginally increased for cooling energy. As a result of energy performance analysis through simulation, in the case of energy demand, heating showed a reduction rate of about 47.7 % from 64.6 kWh/m2a to 33.8 kWh/m2a, and cooling showed a reduction rate of 21.6 kWh/m2a to 22.4 kWh/m2a. It increased by about 3.7 %.
It was confirmed that the total energy demand decreased by about 25.9 % from 116.0 kWh/m2a to 86.0 kWh/m2a. In future, by reflecting the on-site measurement values, we plan to analyze the energy-saving values before and after green remodeling improvement and contribute to the activation of zero-energy buildings.
