We have established the system evaluation method in order to estimate the energy saving effect of the cold air distribution system. By this method, we calculated the systems' annual electric consumption. According to the AHU (s) location-one on the basement floor for whole building or one for each floor, distribution air temperature -16, 10 or 6℃, and chilled water supply method from the ice storage tank (s) -directly or indirectly with a heat exchanger. In case of small stories buildings, annual electric consumption for the central AHU system with cold air distribution is the lowest. In case of large stories buildings, in which each AHU is located on each floor, annual electric consumption for cold air distribution system of 10℃ is the lowest. As the cold air distrbution systems of 6℃ need more volume of chilled water, they spend more electricity than the normal air supplying system of 16℃.
