数据中心在我们的经济中是一个不断增长的能源用户。虽然我们的IT设备每瓦的性能继续呈指数级增长，但这种能源性能的改善仍然超出了不断增长的需求。因此，数据中心的效率必须继续提高。除了效率之外，许多数据中心现在正致力于在数据中心、站点或校园的其他区域重新利用其浪费的能源。如何通过度量和测量来解释这一点是本文的主题。 讨论了能源再利用有效性度量；详细介绍了该指标的发展和应用。还考虑了ERE与PUE（电力使用效率）的结合使用。引用:ASHRAE会议论文，蒙特利尔，QC

Data Centers are an ever increasing user of energy in our economy. While the performance per watt of our IT equipment continues to increase exponentially, this energy performance improvement is still outstripped by increasing demand. Because of this, the efficiency of data centers must continue to improve. Beyond just efficiency, many data centers now are working towards reuse of their waste energy in other areas in the data center or on the site or campus. How to account for this, through metrics and measurements, is the topic of this paper. The Energy Reuse Effectiveness metric or ERE is discussed; both the development and application of the metric are looked at in detail. The use of ERE in conjunction with PUE (Power Usage Effectiveness) is also considered.
