This paper purposes on the development of energy management framework, focusing on the superstores in South Korea. Those superstores are usually huge retail outlets, operating for a long time, and thus requires a large amount of energy consumption. Nevertheless, few attempts have been made to identify the energy management issues in the superstores and to propose the way to improve their energy management systems. To meet this needs, we firstly analyzed the over trends of energy use in South Korean superstores using various energy efficiency indices. Then, on two stores chosen as our case targets, in-depth analysis was carried out in terms of their current energy use and capabilities to reduce the energy use. The research findings are expected to support energy manager’s strategic decision-makings at the firm level and further to contribute to the CO₂ reduction at the national level.
