Simulation of water dissipation in urban buildings Available to Purchase

Building water dissipation (BWD) refers to the change of water into vapour during water use activities in the building. The intention of the work described in this paper was to explore the BWD mechanism and establish a calculation model for BWD. The main research methods included experimental monitoring, a questionnaire survey and data mining. The results of this work showed that the capacity of buildings and the building area determine the type of water dissipation whereas the building population determines the BWD volume. The BWD calculation model was thus built based on two key parameters – building area and building  population. Multi-variate regression fitting was used to analyse and study the other factors that influence BWD, such as water consumption, number of floors and so on. Using cluster analysis, 100 sample buildings were divided into different categories. Ordinary least squares regression was used to fit the multi-variate regression for the BWD of sample buildings. The results showed that the classification of buildings by cluster analysis can enhance the fitting effect of multi-variate regression of BWD.
