The purpose of this study is to develop a calculation tool, which is able to simulate overall energy consumption of air-conditioning systems, electric systems and plumbing systems for buildings. The first report (part4) outlined the framework and system that facilitate especially the development of a simulation tool, which enabled the design of plumbing systems as well as calculating energy and water consumption spent on system operation while contributing to the conservation of energy and water sources. This paper discusses water supply calculation modules, calculation method in these modules and several case study results.
