Earlier this month the Green Grid launched an online tool to help data centre managers assess available free cooling in various European locations. (North American and Japanese versions were available earlier in the year).
The free tool and associated maps are designed to help data centre and facilities managers determine how much outside air is available for data centre cooling and hence can reduce energy use and costs. Users input their country and city names plus specific variables, such as local energy costs, IT load and facility load, to determine the potential energy savings. The tool, which covers 33 European countries, also provides information about savings that could be obtained using water-side economizers.
Members of The Green Grid will have access to a high resolution graphical map of the estimated hours of air-side and water-side economization possible for Europe and many specific countries. The low resolution version is freely available online (see below).
The tool is based on hourly observations from 608 weather stations throughout Europe taken between 1999 and 2008.
This sounds like a useful tool in looking for ways to reduce data centre energy and emissions. Managers need as much background data as they can get to support a move towards more energy efficiency. It’s going to become increasingly important as data centre’s start to fall within emissions legislation, as is now happening with the Carbon Reduction Commitment (CRC) in the UK.
