A123 Shopping sanitary demand

Demand analysis of sanitary accommodations for toilets in large shopping malls

Brief:

This study develops a quantitative mathematical model of sanitary demands from occupants in shopping complexes. In-suit measurements and interview surveys with occupants were conducted in typical local shopping malls in order to determine the model parameters for their visiting patterns, load patterns, demand patterns and their preferred or acceptable duration for waiting and using water closets. The model is used to assess the probable acceptance of sanitary facilities towards the acceptable amount of time for waiting at a typical female washroom designed for an occupant load of 600 occupants in a shopping mall. The results showed that the current sanitary provisions for female washrooms in local shopping malls could meet occupants’ minimum expectation, while with an additional 33% of WC, the sanitary would fully satisfy ‘all’ occupants in terms of amount of time for waiting.
