There has been a variety of studies, policies, and systematic approaches to reducing the energy use to mitigate greenhouse gas emissions, one of the leading causes of global warming. Nevertheless, Seoul's electric power consumption has not decreased. In this study, the electric energy consumption of all buildings in Seoul was analyzed by the unit of administrative dong. Based on this, the implications for the policy to electric energy consumption in the city were suggested. Since Korea has four distinct seasons, the factors influencing electric energy consumption were classified into three categories: physical, social, and seasonal. Hierarchical regression analysis was performed to reflect each variable's characteristics and to determine the degree of influence, and the following analysis results were derived. First, the physical factors of the city affect the power consumption of buildings. Second, the electricity consumption of buildings is highly correlated with the actual economic activity of the city. Third, the power consumption varies by season, and each season has a different effect on power usage. These results imply that different criteria for each season should be applied when establishing a policy for saving electric energy, and the priorities of policies should be reflected according to the degree of impact.
