Abstract

This review systematically examines the fragmented research landscape on building energy system resilience, focusing on its definition, assessment, improvement, and optimization. An analysis of 145 publications reveals the various definitions related to power outage capacity, thirty assessment parameters, and twenty-eight improvement strategies. And approximately half of these publications further explore the optimization of these strategies. The analyses identify several key challenges, including a lack of metrics covering different perspectives (different stages, events, and resilience dimensions), integrated demand-supply-storage improvement strategies, optimization of existing strategies, and a focus on climate adaptability, vulnerable groups (such as the elderly), and emerging technologies (such as AI). Based on these challenges, a key issue is to integrate concepts including climate adaptability, reliability, robustness, and traditional narrow resilience. And then, five future directions are proposed: increasing focus on specific subjects and conditions, emphasizing responses to different and integrated disasters, developing comprehensive assessment metrics, developing full-cycle resilience strategies with multi-objective optimization, and integrating AI-based tools. In response to challenges and future directions, this review attempts to propose a novel resilience assessment, improvement, and optimization roadmap based on multi-type flexible energy resources. This roadmap can address various indicators, events, phases, systems, and strategies, employing light-weight assessment parameters and parallel improvement strategies. A case study confirms its feasibility, demonstrating a 21.13% reduction in annual costs under normal conditions and savings of 34,900 USD during a typhoon day. This study provides valuable insights and actionable guidance for developing the definition, assessment, improvement, and optimization of building energy system resilience.
