A regulatory approach for potential energy efficiency requirements on computer servers

This paper discusses of the feasibility of ecodesign requirements on computer servers and presents a case study. Computer servers have been analysed in an ecodesign preparatory study. For the most representative products, the least life cycle cost (LLCC) has been identified: it minimizes the total cost of ownership for the consumer and fosters manufacturers to improve their products with existing technologies as well and providing the optimum level from a regulatory perspective. On the basis of the LLCC assessment and related product efficiency level, ecodesign requirements can be proposed, bearing in mind the principle of technology neutrality and pushing the market towards increased efficiency levels. The preparatory study confirmed that computer servers are products responsible for a significant share of electricity consumption in the EU. Ecodesign requirements could result in environmentally effective and sustainable policy options, also from an industry competitiveness perspective. The requirements may cover hardware aspects, in particular efficiency of the power supply units, operating temperature and product's efficiency, both in idle and active state. For the latter, the presence of standardized and accurate testing methods is crucial. Moreover, possible resource efficiency requirements may be proposed, in particular to promote reparability, reusability and recyclability. In order to help identifying the best regulatory approach, several policy options are outlined.
