历史建筑面临着与能源消耗相关的各种挑战，尤其是围绕潜在改善机会的挑战。在美国，空间调节（供暖、制冷和通风）可以占家庭能源消耗的一半。因此，确定提高能源效率的成本效益方法对房主和企业来说都是关键信息，也是潜在货币投资和回报的可测量估计器。本文对一栋两层住宅在其城市历史保护委员会的保护下进行了几次建筑翻新的纵向研究。这是之前在samelocation进行的研究的延续，该研究侧重于使用固定能源消耗的差异- 速度和变速热泵系统。在本研究中，考虑了两年内的能源使用情况，具体的建筑和设备改造分为单独的案例研究。将能耗数据与电气和热力测量、气象条件和公用设施记录进行对比分析，以建立整个研究期间进行比较的基线参考。这些发现说明了每次翻新的个人和综合影响，以及在各种动态环境下的性能。引用:2021个虚拟会议技术论文

Historical buildings incur diverse challenges associated with energy consumption, specifically those surrounding opportunities for potential improvements. Inthe U.S., space conditioning (heating, cooling and ventilation) can account for up to half of all the energy usage within a home. As a result, identificationof cost-effective methods towards enhancing energy efficiency represents critical information for homeowners and businesses alike, and a measurableestimator of potential monetary investment and return. In this paper, a two-story residential home under the protection of its city’s historical preservationcommittee is evaluated in a longitudinal study during several building renovations. This is a continuation of previous research conducted in the samelocation, which focused on differences in energy consumption using a fixed-speed and variable-speed heat pump system. Within this study, energy usage overa two-year period is considered, with specific building and equipment modifications divided into individual case studies. Energy consumption data isanalyzed against electrical and thermal measurements, meteorological conditions, and utility recordings to establish a baseline reference for comparisonacross the entire study time period. These findings illustrate both the individual and composite impacts of each renovation, and performance under avariety of dynamic environmental circumstances.
