Abstract

Energy performance evaluation before and after gree remodeling is important for effective green remodeling, and analysis tools and programs are used for this. This study aims to develop programs and verify performance that can be easily used by users without expertise, can be applied to non-residential buildings, and can support accurate energy performance analysis and decision-making during green remodeling. For accurate energy analysis, EnergyPlus, a verified energy analysis program, was installed inside the program as an analysis engine. The user mode may be divided into a general user mode and a professional user mode. In addition, the input method was optimized using a database. The energy analysis performance was verified by comparing the simulation results of the program developed for buildings that have been actually remodeled with the simulation results of EnergyPlus. As a result, there was an error of 4.7% in annual energy use before green remodeling and 8.9% in annual energy use after green remodeling. It is suitable for evaluating energy usage before and after actual green remodeling. However, it seems that there is an error in energy performance analysis due to differences in the process of modeling the shape of a building. Therefore, it is necessary to supplement and improve the program by conducting verification on buildings of various sizes and shapes in the future.
