Efficient energy use in the ICT sector

Efficient energy use in the ICT sector is an issue that is rapidly gaining in importance. On this webpage CE Delft reports on the results of recent studies carried out for some of our clients.

Energy use of datacentres in 2015

In a study for Hivos, ‘Energy consumption of Dutch commercial datacentres, 2014-2017’, we conclude that this consumption stood at 1.62 TWh in 2014. In the years through to 2017 a substantial rise in both data centre floor area and energy consumption is anticipated, with the former rising more rapidly (+100% and +60%, respectively). This report is an update of the relevant section of a 2012 CE Delft report, in which datacentre energy consumption was assessed for the period through to 2015.

Optimum cooling of server rooms

In this study, Improved energy efficiency through BAT for cooling server rooms, carried out for the Netherlands Enterprise Agency (RVO), we assessed the potential scope for reducing the energy consumption of cooling systems in server rooms operated in the Dutch business services sector. The study comprised a series of interviews with both suppliers and specialists with hands-on experience, a literature study and a synthesis of the acquired information with model calculations. It is concluded that use of new cooling techniques can reduce cooling energy by 40-50% in typical situations, and in some cases by as much as 80%. The project has resulted in RVO including a whole raft of energy-efficient cooling technologies for server rooms in the ‘EIA list’ for 2015, thus alerting Dutch businesses to the options available for improving their energy efficiency.

Ultra-efficient new-build datacentres

There are numerous energy-efficient techniques available for new-build datacentres with which substantial energy savings can be achieved and CE Delft has analysed some of the most promising concepts. The study examines both the technical performance and the economic feasibility of several variants. The validated results show that an Energy Use Efficiency (EUE) of below 1.2 is feasible, an efficiency very close to the theoretical maximum.

The study was conducted for NL Agency. The results are relevant for investors in new-build datacentres and for governments responsible for enforcing legislation on energy use.

Carbon footprint of ICT and software systems

CE Delft helps organisations reduce the carbon footprint of their services and products. For several large organisations we help monitor performance of their ICT over time, focusing on new ways of reducing that footprint.
