The high-resolution Energy use data of a large scale complex facility was analyzed. This data included the energy consumption of each air-conditioning zone in the office area, energy consumption of each tenant in the retail zone, and separate energy consumption data for lighting, plugs, fans, cooling, and heating. The result for the change in energy consumption in the retail zone for four years shows that the energy consumption had been decreased by visualizing the energy use of each tenant. The accuracy of estimation of the total energy consumption in the office zone with initial low occupancy is evaluated. The breakdown of energy end-use for the office zone and retail zone are quantified separately. Regarding the variations in energy consumption intensity, there are large differences depending on the type of tenant. With regard to the variations among the same kind of tenant, retail shop is the smallest, and restaurant, which consumes a large amount of energy, is the largest. The difference in energy consumption intensity in the office is about 3 times, and the variation in energy consumption for lighting and appliances is the largest among energy end-uses. The annual energy consumption for lighting and appliances is influenced by the energy use during operation rather than the operating time.
