The review of the Computer Regulation EU No 617/2013 (EU) (Lot 3) did not provide a testing method for energy use/efficiency when in on-mode. To address this gap, the European Commission indicated that it would welcome support developing an on-mode test method for computers. CLASP contacted the Commission and offered to assist on this topic, by developing a first version of a software tool that would quantify both energy consumption and performance of different computer configurations across several operating systems. The Commission then invited CLASP and its Team (GTD and Intertek UK) to present their concept to key stakeholders to determine whether this idea should be taken forward.
On 13 January 2021, the Commission convened a meeting to introduce this first version of the software to members of the Consultation Forum so they are aware of the tool and are able to use it. This page has been created in support of that meeting and to share the tool with stakeholders.
