The loads of cold and hot water consumption are changing by progress of water supply systems and spread of the water-saving fixtures aiming for energy saving in the various buildings. 0n the other hand, people's life style has also been changing by various factors, for example, social, economical, cultural factors and so on. Under these situations, it is necessary to adapt the calculating method to the changing loads for the design and maintenance of buildings. The authors have advanced the development of calculating method based on the data of water consumption for daily, hourly and instantaneous loads in the time series through a day by using a personal computer. In this paper, we carried out the questionnaire investigation about the household's behaviors using hot water and the measurement of cold and hot water consumption per month and per hour in the apartment houses located in Sanin and Sanyo areas. The survey areas were supplied the different cold water temperature because of the separate two sources such as the river water and ground water. Using these data measured fol one year, this study aims at getting various basic data adapted the calculating method for the loads of water and the supply syste's capacity and developing the relationship between the cold water temperature and the usage ratio of cold and hot water demands.
