A refrigeration warehouse is an important facility which supports eating habits of the citizens as an important point of a cold chain. Since its energy demand is also high, it is necessary to clarify the actual condition of an energy consumption. In this paper, it is illustrated through a field investigation of refrigeration warehouses in Tokyo. As a result, these refrigeration warehouses were classilied into six groups according to the energy intensity. Moreover, the present data of energy intensity is compared to the data of 30 years ago about the same institution. Although most of these groups have increased annual energy consumption, they have decreased annual energy intensity. Meanwhile, the energy intensity of these refrigeration warehouses is on the decline compared to other facilities.
