Abstract It is necessary to know widely the equipment condition of individual system in energy-saving design for large-scale public buildings. Based on the actual statistical data of energy consumption obtained from a commercial office building and a hotel，the power consumption　/　unit area by some basic power consuming devices monthly，daily / typical month and hourly　/　typical day is compared, their rule in electricity consumption is summarized, and potential in energy-saving is analyzed.

Key words　Energy consumption feature in large - scale public building　Energy consumption　Electricity consumption　/　unit area

摘　要　大型公共建筑的节能设计，首先需要全面了解建筑物各系统的设备状况。通过某商业办公楼和酒店建筑能耗实际计量数据，比较了几种主要耗电设备能耗的逐月、典型月逐日、典型日逐时单位面积电耗，总结了其用电规律，分析了其节能潜力所在。
