When customers operate their equipment poorly, the time has come for Product-as-a-Service. The cooling of large building complexes such as shopping centres, university campuses or offices is a case in point. In this episode, Dave Mackerness, Director at kaer, explains how Cooling-as-a-Service work. By optimising the equipment, connecting it and operating it much more efficiently, Cooling-as-a-Service can yield cost and emission reductions. This episode is the 14th in the series PaaS Decoded, 16 conversations about the fine details of product-as-a-service.
