美国能源部 (DOE) 发起了一项研究，旨在确定通过广泛部署控制、消除故障和使用更好的传感技术在商业建筑中可实现的国家节约。该研究估计了 9 种建筑类型和 16 种气候下 34 项措施的节省量。这些建筑占美国商业建筑部门能源消耗的近 57%。除了单独的措施之外，还制定了三套措施来估算节省量：(1) 高效建筑，(2) 典型建筑，以及 (3) 低效建筑。结果显示，所有建筑类型和气候条件下都具有巨大的节能潜力。对于每项措施，在所有气候条件下，按建筑类型汇总的场地总潜在节省量在 0% 到 16% 之间变化。对于每项措施，所有建筑类型和气候条件下的总场地潜在节省在 0% 到 11% 之间变化。所研究的所有建筑类型的全国潜在场地节能率为 29%。在所有建筑类型中，节省的场地能源节省量约为 1393 PJ（1.32quads），或主要（或来源）能源节省量为 2912PJ（2.76quads）。推断本研究中未分析的其他建筑类型的结果，主要节能可能在 4220 至 5275 PJ 范围内。相比之下，2015 年美国所有能源使用部门的一次能源消耗总量为 102,762 PJ（97.4quads）。这使得商业建筑控制的改进对于持续减少国家能源消耗具有重要的战略意义。为了实现大部分潜在的节省，可以按照本文的建议通过研究开发和部署 (RD&D) 来解决许多差距。
The US Department of Energy (DOE) sponsored a study to determine the national savings achievable in the commercial buildings through widespread deployment of controls, elimination of faults, and use of better sensing. The study estimated savings from 34 measures in 9 building types and across 16 climates. These buildings are responsible for almost 57% of the US commercial building sector energy consumption. In addition to the individual measures, three packages of measures were created to estimate savings: (1) efficient building, (2) typical building, and (3) inefficient building. The results showed significant potential for energy savings across all building types and climates. The total site potential savings by building type aggregated across all climates for each measure varied between 0 and 16%. The total site potential savings aggregated across all building types and climates for each measure varied between 0 and 11%. The national potential site energy savings across all building types studied is 29%. Across all building types, the savings represent approximately 1393 PJ (1.32 quads) of site energy savings or 2912 PJ (2.76 quads) of primary (or source) energy savings. Extrapolating the results for other building types not analyzed as part of this study, the primary energy savings could be in the range of 4220 to 5275 PJ. For comparison, the total US primary energy consumption across all sectors of energy use was 102,762 PJ (97.4 quads) in 2015. This makes commercial building control improvements strategically important to sustained reductions in national energy consumption. To realize most of this potential savings, many gaps can be addressed through research development and deployment (RD&D), as recommended in this paper.
