在翻新和新建的商业建筑中，现有能源管理和控制系统（EMCSs）的数量非常多，而且还在不断增长。为了评估这项技术对建筑物所有者、居住者、运营商和公用设施的好处，我们从硬件、软件以及系统内和系统间通信能力的角度对市场上现有的机电设备的主要特点进行了审查。文中给出了两种EMCs收集数据的示例，展示了建筑运营商和公用事业公司如何利用收集到的信息记录建筑能耗和峰值电力需求。简要讨论了常用的负荷管理软件。最后，讨论了允许访问驻留在EMC中的数据的通信协议。 单位:I-PCITION:研讨会，ASHRAE交易，1987年，第93卷，pt。1，纽约州纽约市

The number of existing energy management and control systems (EMCSs) in both retrofitted and new commercial buildings is significant and growing. To assess benefits of this technology to building owners, occupants, operators, and utilities, the major characteristics of EMCS currently available on the market have been reviewed in terms of their hardware, software, and intra- and intersystem communications capabilities. Examples of data collection by two types of EMCSs have been given to show how the gathered information could be utilized by both building operators and utilities to document energy consumption and peak electricity demand in buildings. A brief discussion of the commonly offered load management software is presented. Finally, communication protocols that allow access to the data resident in the EMCS are discussed.Units: I-P
