Abstract: Energy saving is a significant aspect in terms of building design. In Hong Kong, domestic freshwater consumption occupies over half portion of total freshwater consumption. Under the increasing trend of population density, energy use with respect to water supply will keep raising with time. Optimal water supply system is important for sustainable building design, which can satisfy the water demand of the inhabitants while saving the energy. In term of energy saving, published method developed by to evaluate the energy efficiency should be adopted for comprehensive design of water supply system. To reduce the energy consumption in the water supply system, a myriad of parameter should be put into consideration, including demand flowrate, design flowrate, volume of water tank storage, duration, and occurrence of pumping system. In this paper is aim at finding out the correlation between the break tank, the pump system, and the root tanks. The process will be mainly conducted by simulation using Fortran programming. Data like water demand and required outflow rate of the root tank will be obtained from previous simulation of other researchers. Base on the water pressure provide from the street pipes, the position of the break tank will be one the parameter in our simulation. With the thorough design of the water flowrate of the break tank as well as the roof tank, operation of pumping system, the volume and the position of the tank, we want to see how mass balance according to the required time-varied water demand can be achieved with high energy efficiency.
