Abstract: The attention to reduce energy consumption stems from the growth of urbanization and the idea of "sustainability". This is a cause of concern, as the growth of urbanization is increasing at an alarming rate. Electricity consumption in Hong Kong in 2010 was 151 TJ, with 30% accounted for by air-conditioning, which 72% by non-domestic buildings. In order to determine the optimized distribution pump placement was performed on three different scenarios of a 40 storey office building. The difference in the three scenarios are the load distribution of the building which were varied as well as pump placements. From the detailed analysis of the three different scenarios varying the pump placements at various heights, three different polynomial equation were derived and from this results suggested that there could be reduction of power consumption for all three scenarios. The reduction in the three scenarios varied from 54% to approximately 64%. There are limitations to the polynomial equations derived as these would depend on the design criteria used by the designer. In order to support the findings found in this research future recommendations are made in this dissertation.
