The world is seeing a rapid increase of cooling of buildings1. This is driven by multiple factors, such as urbanization and densification, climate change and elevated comfort expectations together with economic growth in hot and densely populated regions of the world. Additionally, disruptive events, such as extreme heat and heat waves are occurring more often and are expected to become a common phenomenon by mid-century. The trend towards cooling seems inexorable. It is therefore mandatory to steer this development towards sustainable solutions.
