Interviewing surveys were made of the usage factors such as the usage frequency and the usage time of WC or urinals, and the preference of facilities or appliances at toilet, etc. Furthermore, the number of sanitary fixture at toilet were calculated by queuing theory simulation. The study then suggests the basic data or guideline for assessing the optimum number of sanitary fixture at toilet based on field survey in office building.
