Climate change is causing a persistent increase in the number of hot summer days. Offices and homes are getting hotter, and the nights bring little respite from the heat. Against this backdrop, a significant increase in new cooling systems installations is anticipated, which in turn will give rise to increased energy consumption. One potential cost-effective alternative is to use existing heating systems. According to an analysis by the Fraunhofer Institute for Building Physics IBP, the heat pumps in these systems can be reverse operated to provide effective cooling.
