本文以一个大型实验室研究设施为例，介绍了性能监测和运行评估以及后续分析如何识别潜在的节能。该项目强调了作为过程一部分的简单能源监测技术的好处。能源监测方法包括对现有楼宇自动化系统收集的数据进行结构化审查，发现了一些运行故障。这些故障导致能耗增加约8%（4.0E9 Btu，1.2E6 kWh），超过了估计的建筑供暖和制冷总能耗（5.0E10 Btu，1.5E7 kWh，估计72.6万美元）。通过对建筑能源系统的详细模拟，可以比较不同的控制策略。 模拟结果表明，该设施目前的建筑供暖和制冷能源需求可能会节约25%以上。通过建筑模拟确定的潜在节约比通过能源监测方法获得的节约要高，但创建模拟所需的时间和精力也要高得多。虽然这里的重点是一个单一的实验室类型的研究大楼，但研究结果可能会推广到其他设施。单位:双引文:ASHRAE交易，第113卷，第。2.

This paper presents a case study of how performance monitoring and operational assessment coupled with subsequent analysis led to identification of potential energy savings for a large laboratory research facility. This project highlights the benefits of simple energy-monitoring techniques as part of the process. The energy-monitoring method consisted of a structured review of data collected by the existing building automation system, which revealed a number of operational faults. These faults resulted in an increased energy consumption of approximately 8% (4.0E9 Btu, 1.2E6 kWh) over the estimated total annual building heating and cooling energy (5.0E10 Btu, 1.5E7 kWh, estimated $726,000). A detailed simulation of the building energy systems enabled comparison of alternative control strategies. The simulation results indicate the potential for savings of more than 25% of the facility’s current building heating and cooling energy requirements. The potential savings identified with building simulation are higher than obtained for the energy-monitoring approach, but the time and effort required to create the simulation were also substantially higher. While the focus here was on a single laboratory- type research building, the findings may be generalized to other facilities.Units: Dual
