Energy efficiency of high-rise water supply system designs

Brief:

Energy efficiency of water supply systems in high-rise residential buildings becomes a concern for sustainable development nowadays. This paper presents a measure of energy efficiency for water supply system designs. The energy efficiency is the potential energy of the water demands in buildings divided by the pumping energy required. A mathematical model for optimizing pumping energy is illustrated through example arrangements of water supply systems in a building. To demonstrate that the model is useful for establishing optimal design solutions that integrate energy consumption into urban water planning processes which cater to various building demands and usage patterns, measurement data of high-rise residential buildings in Hong Kong are employed.
