Abstract: With more and more attention to the sustainable development, the sustainable development of buildings is necessary. This study is an assessment of energy performance of International Commerce Center (ICC) in Hong Kong. The energy consumption data of ICC are measured or calculated by monthly energy bills, power metering system and IBmanager system.The energy consumption data of power metering system is the main problem. This part has four steps including Build Structure Tree, Classify The Facility, Data Collection and Check. Through comparing the percentage of whole energy consumptions of different system and the efficiency of different facility to the standard or the similar type of a complex building in Hong Kong, it showed a fair and corrective assessment on the energy use of this building. The final objective is to improve the efficiency of high energy consumptions. On the whole, the results of the assessment of the energy performance of ICC is that the efficiency of energy performance in ICC is high. The annual energy consumption of whole building in 2011 is about 52.0 million kWh. HVAC system is the most significant and the largest energy consumer, with energy proportion of 69.4%. The energy use intensity (178.7 kWh/m²) and cooling demand intensity (320 kWh/m² are very low compared with the similar type of complex building in Hong Kong. The energy consumption of Lighting &Equipment is only 17.6%, while the Lift system contributes about 8.2%, which is larger than the weighting in other office buildings. This study indicates the energy performances of lighting and office equipment are energy efficient while some possible energy wastage may exist in lift system.
