Abstract

The market size for green remodeling continues to increase as domestic and abroad policies and supporting systems for green remodeling of existing buildings are actively underway. For a successful green remodeling project, the energy characteristics of the existing building must be identified with energy performance analysis tools. Therefore, this study investigated the trends in national policies and supporting policies for green remodeling and compared the scope and characteristics of energy performance analysis tools for the analysis of green remodeling technologies. In order to conduct an energy analysis on existing buildings, the ISO13790-based quasi-steady analysis tool was developed considering policies and the situations of each country, and dynamic analysis tools such as EnergyPlus, TRNSYS, IDA-ICE and ESP-r were used for the investigation. The quasi-steady analysis tool has simple configurations for input items and levels of analysis factors; therefore, it is relatively easy to use and takes a shorter time for analysis. On the other hand, dynamic analysis tools are configured with multiple complex input items; thus, they require more specialized knowledge. However, they provide detailed simulations on actual buildings. Therefore, we suggest that a quasi-steady analysis tool is effective for evaluating legal standards in a short period of time, and the use of dynamic analysis tools is required for detailed energy analysis in accordance with building characteristics and key technologies.
