*The greengauge represents the aggregate savings of powerPerfector installations in the UK, Ireland, Cyprus and Denmark. Savings correct at the time of installation using either IPMVP savings analysis or reasonable estimates, where savings analysis was not possible. Actual savings may change over time for example due to energy pricing, occupancy, equipment, rates, building re-purposing and further energy efficiency measures.
