摘要 逐时使用率对于预测办公建筑照明与插座系统电耗,以及核定节能改造的节能量有十分重要的意义。选取重庆17幢办公建筑作为研究对象,根据建筑全年逐时照明与插座系统的实测电耗数据,计算各建筑全年每个工作日24h的逐时使用率。利用聚类分析方法,根据日逐时使用率的不同,将办公建筑快速分为3类。根据是否经常加班以及午休时是否关闭部分用电设备,可以快速判断办公建筑属于哪一分类。最后对3类建筑分时段计算典型逐时使用率,便于实际应用中快速查询。 The hourly usage ratio is very important for lighting and equipment energy predicting of office buildings and energy saving calculation of energy efficient retrofit. 17 office buildings in Chongqing were selected to calculate daily usage ratio by using whole-year electrical consumption data of lighting and equipments energy system. According to the different hourly usage ratio, office buildings have been categorized into two main types by using cluster analysis method. Then, the typical hourly usage ratios of two types of office buildings were calculated.
