Abstract
In resent years, booster pump system has increased as water supply system. In this system, it is estimated to have many hours for pump operation. Therefore we have some concerns about excessive energy consumption caused by this pump system. In this paper, we measured the volume of supply water by booster pump system in an office building, and also we clarified about the condition of pump operation and the amount of electric power. In addition we estimated the volume of supply water and the amount of electric power by simulation technique. As a result, we showed that it was possible to hold down the increase of the consumption of electric energy by using the suitable water supply system on the basis of the high accuracy for water supply demands estimation.
