perto is an energy efficiency service provider for large properties. We concentrate on heating systems in old & mid-sized buildings with outdated technical equipment. Our goal is to minimise the waste of energy resources and turn them into sustainable, sensible investments. We developed “pertoIOTA” – an IoT-platform to apply Efficiency as a Service (EaaS) for energy systems to monitor, control & automate with Distributed Artificial Intelligence. We help property owners to save energy, money, and carbon emissions through the upgrading of building systems and the replacement of inefficient devices.
