Characteristic analysis of peak load in electricity on large scale hotels considering the energy efficiency

The demand for electricity in Korea has been on the rise due to economic growth, changes in weather conditions, and the widespread use of electric devices. The excessive demand for electricity that used to occur only during the summer now occurs during the winter as well. As a result, it is now necessary to manage the electricity load of buildings in a stable way. The study is intended to analyze the possibility of reducing the entire electricity load and electricity peak load through an improvement in the energy efficiency of hotels buildings that are typical high energy consuming buildings, and to propose a plan to reduce electricity peak load through a decrease in the entire electricity load. Using the electricity load data of the hotel buildings, the properties of electricity load and the correlations between building energy efficiency rating and electricity peak load were analyzed. In so doing, this study can contribute not only to reducing the peak load of buildings, but also leveling off energy supply and load through a reduction in the nation's largest electricity demand.
