The environment and energy conservation are two of the most frequently discussed social issues world widely. Though seemingly unrelated and being historically far from environmentally friendly, sports facilities are also closely linked to those issues as the trend of building and managing sports facilities is currently changing towards more green and sustainable way. Applying renewable energy sources to supplement energy consumption of sports facilities has been attempted in various ways. However, operating a sports facility solely with renewable energy embeds some barriers as renewable energy sources are influenced by external environmental factors. Sports facility is especially sensitive to stable energy supply because sporting events might have to be suspended and cause the audience in a dangerous situation when energy is insufficiently supplied. This study analyzes a renewable energy hybrid system for the Munhak Stadium in Incheon, Korea. The current hybrid system with photovoltaic (PV) panels will be analyzed first; then, another set of simulations will be performed under conditions in which additional PV panels are installed. The current and future hybrid systems for Munhak Stadium’s future can be analyzed for optimal performance by conducting this series of simulations.
