加利福尼亚州阿卡迪亚市一栋82000平方英尺办公楼的业主安装了一个能源管理系统，该系统结合了需求控制，以避免南加州公用设施的使用时间。对于所有需求大于500千瓦的建筑，使用时间率是强制性的。这座全Electroxic建筑采用了带有电再热的可变风量系统，冷却来自四台60吨的压缩机。在实行需求控制之前，该建筑的月平均需求为540千瓦； 安装后，平均功率为398千瓦。当需求超过450千瓦时，开始甩负荷。甩负荷的优先顺序是:（1）电、水加热，（2）内部区域再热，（3）外部区域再热，以及（4）压缩机。最初，人们认为最大的需求节约将发生在天气温和的月份。事实证明，这种观点是错误的。从公用事业公司的计费数据磁带和大楼的EMS系统中收集了小时需求数据的摘要，本文对此进行了介绍。 由于需求控制，业主每月平均可节省800美元（每mc）ntli。单位:I-PCITION:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

The owner of a 82,000 ft2office building in Arcadia, California, installed an energy management system incorporating demand control to avoid a southern California utility's time-of-use rate. The time-of-use rate is mandatory for all buildings with demands greater than 500 kW. This all-electxic building utilized a variable air volume system with electric reheat, and cooling is from four 60-ton compressors. Before demand control was instituted, this building's monthly average demand was 540 kW; after installation the average has been 398 kW. Load shedding begins when demand exceeds 450 kW. The priority of the load shedding is: (1) electric, water heating, (2) internal zone reheat, (3) external zone reheat, and (4) compressors. Originally, it was believed that the greatest demand savings would occur during months with mild weather. This belief has been proven false.Summaries of hourly demand data were collected from the utility's billing data tapes plus the building's EMS system and is presented in this paper. The owner has experienced average monthly savings of over $800 per mc)ntli resulting from just demand control.Units: I-P
