建筑行业消耗了美国75%的电力，提供了大量的能源、成本和二氧化碳排放节约潜力。新技术使建筑物能够灵活地管理一天中不同时间和季节的电力负荷，以支持低成本、低碳的电网。评估这些技术的价值需要以更高的时间分辨率了解建筑电力负荷的变化，而不是之前对美国建筑效率潜力的研究。我们采用Scout（美国建筑能源使用的开放获取模型）来描述全国范围内基线建筑用电量、成本和排放的次年度变化。我们将这一基线应用于对不同程度的能源效率和灵活性的能源、成本和二氧化碳排放节约潜力的时间敏感分析中，发现效率在时间敏感的评估框架中仍然具有很强的价值，而灵活性的价值取决于假设的电价、测量幅度和持续时间，以及效率已经捕获的节省量。
The building sector consumes 75% of US electricity, offering substantial energy, cost, and CO2 emissions savings potential. New technologies enable buildings to flexibly manage electric loads across different times of day and season in support of a low-cost, low-carbon electric grid. Assessing the value of such technologies requires an understanding of building electric load variability at a higher temporal resolution than is demonstrated in previous studies of US building efficiency potential. We adapt Scout, an open-access model of US building energy use, to characterize sub-annual variations in baseline building electricity use, costs, and emissions at the national scale. We apply this baseline in time-sensitive analyses of the energy, cost, and CO2 emissions savings potential of various degrees of energy efficiency and flexibility, finding that efficiency continues to have strong value in a time-sensitive assessment framework while the value of flexibility depends on assumed electricity rates, measure magnitude and duration, and the amount of savings already captured by efficiency.
