The Headquarters Department of the Army sponsored a study to determine the national impact of deploying the Re-tuning™ (“Re-tuning” is a trademark of the US Department of Energy) methodology in five building types that account for over 40% of the Army’s conditioned building stock. Re-tuning is a systematic process that improves operational efficiency and reduces energy consumption at no or low cost through the building automation system by correcting operational problems that plague buildings. The study relied on successful demonstration of the Re-tuning methodology at four pilot US Army installations that informed a holistic effort, including simulating 12 individual Re-tuning energy efficiency measures (EEMs) and six packages of EEMs in five selected Army building prototype models that represent 311 million ft² (28.9 million m²) of the Army’s conditioned floor space. Both the baseline buildings and the packages were customized to capture the expected outcomes of Re-tuning a diverse set of buildings. The study highlighted the benefit of individual Re-tuning EEMs and economics of implementing packages of EEMs in applicable Army buildings across 16 climates and two building vintages. The average whole-building energy savings ranged from 10.8 to 40.5% by building type, with the company operations facility building having the highest value proposition from Re-tuning. In addition, the study revealed that all large office buildings in the Army are economical to Re-tuning. The total modeled cost savings potential for Re-tuning the five building types across the US Army is $204/1000 ft² ($220/100 m²) or $64 M annually. This cost savings represent 5.6% of all the Army’s energy expenditures.

节省能源成本和预期回报，以重新调整美国陆军建筑物的控制

陆军总部部门发起了一项研究，以确定在5种建筑物类型中使用Re-tuning™（“ Re-tuning”是美国能源部的商标）方法的国家影响。陆军的条件建筑存货。重整是系统的过程，它通过纠正困扰建筑物的运行问题，通过楼宇自动化系统提高了运行效率并以零成本或低成本降低了能耗。这项研究依赖于在四个美国陆军试点设施中成功演示了重整方法，这些方法为整体工作提供了帮助，包括在五个选定的陆军建筑原型模型中模拟12个单独的重整能效措施（EEM）和六个EEM包，代表3.11亿英尺²（2890万米²陆军条件的地面空间）。基准建筑物和软件包均已定制，以捕获重新调整各种建筑物的预期结果。这项研究强调了个别重新调整EEM的好处，以及在16种气候和两个建筑年份的适用陆军建筑物中实施EEM软件包的经济性。按建筑物类型，整座建筑物的平均节能量在10.8％至40.5％之间，其中公司运营设施建筑物的重整价值最高。此外，研究还表明，陆军所有大型办公楼都可以进行重新调整。重新调整全美军五种建筑类型的总成本节省潜力模型为$ 204/1000 ft ²（$ 220/100 m²）或每年$ 64M。节省的费用占陆军所有能源支出的5.6％。
