摘要

住宅建筑节能改造对于提高环境可持续性和降低能源成本至关重要。改造措施的选择受到建筑系统、居住者行为、政府政策、天气变化和气候变化等因素的影响,所有这些因素都会对能源性能产生重大影响。与单个住宅的改造相比,为整个社区评估和选择最佳改造方案具有很大的挑战性,因为目前存在着不同的住宅构成和可变性。因此,工程的稳健性对于确保不同条件下的能源性能和适应性的一致性至关重要。在这种情况下,稳健性指的是改造措施在外部干扰或输入和条件发生变化的情况下仍能保持其功能,并仍然是最佳选择的能力。本研究提出了一个框架,用于评估多种改造措施在不同建筑系统、居住者行为和社区环境情景下的稳健性。该框架包括五个关键步骤:情景模式开发、国家住宅能效措施数据库整合、能效模拟、成本效益汇总和改造方案选择。每个步骤都结合了建筑特点、使用者行为、环境条件、改造方案和评估标准的多样性,从而增强了框架的稳健性。美国密歇根州南部的一个案例研究证明了该框架的有效性,其中包括 63 栋单层独户住宅、121 栋两层独户住宅和 8 栋联排别墅。研究发现,对整个社区而言,炉子改造是最有效的解决方案,在各种方案中都能实现 4.7%-8.0% 的源能耗降低,投资回收期为 10-20 年。这些研究结果与之前的研究结果一致,表明该框架在优化社区规模住宅能源改造方面具有更广泛的应用潜力。

Framework to select robust energy retrofit measures for residential communities
Residential building energy retrofits are essential for enhancing environmental sustainability and reducing energy costs. The selection of retrofit measures is influenced by factors such as building systems, occupant behavior, government policy, weather variability, and climate change, all of which can significantly impact energy performance. Compared to retrofitting individual homes, evaluating and selecting optimal retrofit solutions for an entire community is challenging due to diverse residential compositions and variability present. Therefore, engineering robustness is crucial for ensuring consistent energy performance and resilience across different conditions. In this context, robustness refers to the ability of a retrofit measure to maintain its functionality and remain an optimal choice despite external disturbances or changes in inputs and conditions. This study presents a framework for evaluating the robustness of multiple retrofit measures across various building systems, occupant behaviors, and environmental scenarios at the community level. The framework comprises five key steps: scenario model development, integration of the National Residential Efficiency Measures database, energy performance simulation, cost-benefit aggregation, and retrofit solution selection. Each step enhances the framework’s robustness by incorporating the diversity of building characteristics, occupant behaviors, environmental conditions, retrofit options, and evaluation criteria. The framework’s effectiveness is demonstrated through a case study in southern Michigan in the United States, which includes 63 one-story single-family houses, 121 two-story single-family houses, and 8 townhouses. The study identifies furnace retrofits as the most robust solution for the entire community, consistently achieving source energy reductions of 4.7 %–8.0 % and payback period of 10–20 years across various scenarios. These findings are consistent with previous research, indicating the framework’s potential for broader applications in optimizing community-scale residential energy retrofits.
