We present unprecedented datasets of current and future projected weather files for building simulations in 15 major cities distributed across 10 climate zones worldwide. The datasets include ambient air temperature, relative humidity, atmospheric pressure, direct and diffuse solar irradiance, and wind speed at hourly resolution, which are essential climate elements needed to undertake building simulations. The datasets contain typical and extreme weather years in the EnergyPlus weather file (EPW) format and multiyear projections in comma-separated value (CSV) format for three periods: historical (2001–2020), future mid-term (2041–2060), and future long-term (2081–2100). The datasets were generated from projections of one regional climate model, which were bias-corrected using multiyear observational data for each city. The methodology used makes the datasets among the first to incorporate complex changes in the future climate for the frequency, duration, and magnitude of extreme temperatures. These datasets, created within the IEA EBC Annex 80 “Resilient Cooling for Buildings”, are ready to be used for different types of building adaptation and resilience studies to climate change and heatwaves.

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.

This report summarizes the structure and the outcomes of Annex 80 – Resilient Cooling of Buildings, which was conducted as a five-year international research project within the IEA Technical Collaboration Programme EBC – Energy in Buildings and Communities. Annex 80 covered the spectrum of the following four technology groups: (1) Reducing heat gains to the indoor environment and people environments (2) Removing sensible heat from the indoor environment (3) Increasing personal comfort apart from space cooling (4) Removing latent heat from indoor environment Its outcomes are published in seven official Annex Deliverables. In addition, partial results of Annex 80 have been published in numerous scientific journals. This document provides a comprehensive overview of all deliverables and directs readers to the locations where all related publications can be accessed.

International Energy Agency Energy in Buildings and Communities (IEA EBC) Annex 80: Resilient Cooling of Buildings promotes a rapid transition to the mainstream and preferred use of resilient low-energy and low-carbon cooling systems in buildings. Annex 80 Subtask D (Policy Actions) advances policy-related endeavors that support energy efficiency and resilience in cooling. The Subtask team analyzed product labelling programs; air conditioning minimum energy performance standards (MEPS) and voluntary measures; and building regulations, standards, and compliance requirements, identifying policy gaps and opportunities. It then generated a set of 37 policy recommendations that boost resilience to heat waves and/or power grid failure by reducing heat gain, removing sensible heat, enhancing thermal comfort without mechanical cooling, or removing latent heat. Strategies addressed include advanced solar shading/advanced glazing, cool envelope materials, evaporative envelope surfaces, ventilated envelope surfaces, heat storage and release, ventilative cooling, adiabatic/evaporative cooling, compression refrigeration, high-temperature cooling systems using low-grade thermal energy, comfort ventilation, micro-cooling and personal comfort control, and whole-building solutions. Each recommendation identifies the mechanism(s) through which the policy would be applied and the disruption(s) mitigated; details the what, why, how, who, where, timeline, cost, and potential undesirable side effects of implementation; and suggests a policy model to follow.

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. This report offers a collection of 16 technologies, well suited to form a part of Resilient Cooling solutions of Buildings. It is meant as a package of information for those who are in the position to draw decisions upon building-design, both retrofit and new constructions. The 16 technologies are structured in four main sections, which represent the four general approaches to making a building resilient against heat: - Reducing heat loads to people and indoor environments - Removing heat from indoor environments (production, emission and combined) - Increasing personal comfort apart from space cooling - Removing latent heat from indoor environments Each technology is described in a concise manner, sub structured in the chapters: Description, Key Technical Properties, Performance and Application and Further Reading

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. This midterm report sums up the developments of the Annex 80 since its first Expert Meeting in October 2019 in Vienna, Austria until July 2021. During this period several conference calls as well as the second, third and fourth Expert Meeting have been held by the Operating Agent (OA) and its team. The formation of a common understanding of concepts and definitions of resilience had been the focus of the group during the first period of the annex. Members with different scientific background discussed various approaches and developed an understanding of resilience in relation to cooling of buildings. The group identified two major threats for the cooling of buildings: extreme heat events and power outages. Others such as extreme rain events, flooding, landslides, or storms influence the built environment too but are not as strongly connected to cooling of buildings. Therefore, the group of scientists decided not to address these disruptions. Different task groups were set up to define thermal boundary conditions, generate future weather files and compile key performance indicators for the assessment of cooling technologies through dynamic simulations. The groups summarized their results and published short technical reports. The weather data task group planned to publish their methodology and results as scientific paper.

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. It encompasses the assessment and Research & Development of both active and passive cooling technologies of the following four groups: a) Reduce heat loads to people and indoor environments. b) Remove sensible heat from indoor environments. c) Enhance personal comfort apart from space cooling. c) Remove latent heat from indoor environments. The present review sums up the state of the art in cooling solutions which may be regarded as resilient. Its main objective is to systematically describe the available cooling solutions, their physical basis, their benefits and limitations, their technology readiness level, their practical availability, and applicability. Doing so, the State-of-the-Art Review forms the basis for the work of EBC Annex 80.

Resilient cooling is used to denote low energy and low carbon cooling solutions that strengthen the ability of individuals, and our community as a whole to withstand, and also prevent, the thermal and other impacts of changes in global and local climates, particularly with respect to increasing ambient temperatures and the increasing frequency and severity of heat waves.
