BREEAM Data Centre Scheme Goes Live (Richard Stern)

A scheme which rates buildings’ footprint has been applied to data centres – but will it cut energy use?

A UK-based body has produced a new scheme which should help businesses build green data centres.
The BREEAM rating scheme for buildings, from the Building Research Establishment (BRE Global) has been extended to cover data centres. The new BREEAM data centre scheme is intended to help organisations assess the environmental impact of their data centre, and should be a help as pressure increases for zero-carbon buildings.

The End is Nigh! (Richard Stern)

The project is now coming to a conclusion and the new Data Centre will be handed over to Production in readiness for the I.T. systems to be migrated into the new data centre. All the paperwork has been completed and submitted to the EU Code of Conduct for Data Centres to ensure we have used “best practice” throughout this project. More soon.

The EPA today unveiled its new and long-awaited Energy Star certification for buildings that house data centers (Richard Stern)

The EPA today unveiled its new and long-awaited Energy Star certification for buildings that house data centers and stand-alone facilities, marking a big step forward for energy efficiency in high-tech environments.
The new certification relies on PUE, or power usage effectiveness, to gauge the efficiency of a computing facility. PUE is a metric developed by the Green Grid consortium, and measures how much of total energy going into a data center is used for computing compared to lighting and cooling.
In order to earn the Energy Star label for a data center, the facility must be within the top 25 percent of their peers for PUE, and must be audited by a third party. The EPA collected energy usage information from more than 120 data centers between March 2008 and June 2009 in order to develop the levels.
Data center owners can begin the process to get their facilities certified with the EPA’s online benchmarking tool, part of the Energy Star for commercial buildings certification.
The EPA last year launched its Energy Star for servers rating, one that was met with some skepticism as it was unveiled. Similarly, some industry watchers are worried about the data center certification: Because it relies solely on PUE to measure efficiency, it can skew the playing field for companies located in hotter parts of the country, since it can be easier to get a low PUE in a cold climate.

Energy Star Label for Data Centers (Steve Phipps)

Another day, another energy standard ( hits the streets.

It would be easy for anyone looking to manage data centres efficiently to be confused by the plethora of competing standards emanating from various bodies around the World.  This particular standard builds on your Power Usage Effectiveness (PUE) rating, which is a measurement devised by the Green Grid and recently upgraded to bring in external verification.  The problem is, PUE is a very blunt tool for measuring efficiency and should only really be used internally to an organisation, due to it’s susceptibility to external environmental factors and subjective decisions around what to measure.

So what value will the new rating bring?  I’m tempted to say “none at all”, but as with most things, if there is a commercial or regulatory value in doing something, then there will be an almighty rush to the EPA certification queue!  I think most data centre owners would be better off accrediting against the EU Code of Conduct for Data Centres (EUCoC for DCs).

The best practice techniques encouraged within the EUCoC will give an excellent starting template and provide an opportunity to lower energy, Carbon and operational costs.  Become an Endorser and/or a Participant and you might just gain some commercial benefit too.

As for the problem of proliferating standards, what we need is an holistic view of Sustainable ICT that helps to pull everything together rather than just provide arbitrary ‘kite marks’ against subjective quantitative measures…
