This study analyzed the effects of green remodeling in the consideration of zero-energy building certification on small neighborhood facilities that were completed over 30 years ago. The result of the first energy demand analysis showed 56.8% reduction from 207.0 kWh/㎡·yr before green remodeling to 89.5 kWh/㎡·yr after green remodeling. It was also determined that carbon dioxide emissions would be reduced by 56.7%. For green remodeling of economic zero-energy buildings, the dependence on new and renewable energy should be reduced by minimizing primary energy consumption. This can minimize the burden of energy production if energy consumption decreases. In order to avoid planning to install a PV system indiscriminately, the adequacy review must be preceded by a sunshine simulation analysis. In the future, it is expected that research will be conducted to analyze the effectiveness of technology elements for energy improvement in buildings in the future and the findings will be used to inform building owners implementing green remodeling.
