The purpose of this study is to obtain the basic data of water and gas consumption in the university welfare facilities. These data are useful for the design and planning of eco-campus and the establishment of calculating method for water supply demands in various buildings. We carried out the measurement of water and gas consumption in 6 welfare facilities located on Higashi-Hiroshima campus of Hiroshima University. Each welfare facility have some water and gas meters for charges of the shop's consumption. We recorded the values of each meter by one hour interval from 7:00 a.m. to 9:00 p.m. for one week in each season; autumn, winter, spring and summer. Also, we carried out a questionnaire investigation to get the condition of water usage fixtures, for example toilet and washing machine in each shop. And we get at the number of customers from the cafeteria's and barber's owner. By using these data, we analyzed the daily, hourly water and gas consumption in welfare facilities and in each system; cafeterias, barbers and toilets etc. We studied the relationship of the water and gas consumptions and some fluctuating factors, numbers of customer and times of washing machine's usage.
