International Energy Agency EBC Annex 80 | Resilient Cooling of Buildings – Technology Profiles Report

The world is facing a rapid increase of air conditioning of buildings. This is being driven by multiple factors, such as urbanization and densification, climate change and elevated comfort expectations as well as economic growth in hot and densely populated regions of the world. The trend toward cooling seems inexorable. It is imperative to steer this development towards sustainable solutions. 
Against this background, it is the motivation of EBC Annex 80 “Resilient Cooling of Buildings” 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.  
The main objective of Annex 80 is to support a rapid transition to an environment where resilient low energy and low carbon cooling systems are the mainstream and preferred solutions for cooling and overheating is-sues in buildings. 
This report is a main deliverable of Annex 80 and summarizes the investigated resilient cooling technologies of Annex 80. It provides an overview of cooling solutions and their performance related to resiliency against heat waves and power outages. The Technology Profile Sheets give recommendations for good implementation, commissioning and operation, present barriers to application and show opportunities. These shall support the Annex 80 mission of a rapid transition to an environment where resilient low energy and low carbon cooling systems are the mainstream and preferred solutions for cooling and overheating issues in buildings.
