The world is facing a rapid increase of air conditioning of buildings. It is the motivation of Annex 80 to develop, assess and communicate solutions of resilient cooling and overheating protection. Resilient Cooling is used to denote low energy and low carbon cooling solutions that strengthen the ability of individuals and our community to withstand, and prevent, thermal and other impacts of changes in global and local climates. Within Annex 80, there is a manifold need to use key performance indicators (KPI, i.e. performance metrics). This study employs a structured approach to evaluate Key Performance Indicators for assessing the resilience of buildings across various technologies. All suggested KPIs pertinent to assessing building resilience were collected and listed comprehensively. This involved an extensive review of existing literature, standards, and expert opinions. The aim was to compile a comprehensive inventory of KPIs that encompass diverse aspects of building resilience. Each identified KPI is systematically described to ensure clarity and understanding. This description includes a definition, a list of commonly used synonyms, units of measurement, and sources for the information.
