Green Public Procurement Data Centres – Update (GEN – 854.00)

07 December 2017

3 min read

GEN – 854.00. The number of data centres and the associated energy consumption and related environmental impacts continue to increase. Green Public Procurement is expected to ease the burden on energy and environmental resources and would complement the EU Code of conduct for data centres. 28 persons participated in the first meeting. The preliminary findings are outlined below.

Preliminary findings

The preliminary findings by the Commission on the ‘Scope, Market, Standards and Procurement models’ were commented upon, and the findings of a EURECA study (link included below) will be shared for further review.

The LCA and LCC analysis and technical improvement potential identified three sets of criteria areas: Data centre performance, IT system performance, and M&E systems performance. Yet, it was noted that care was needed in interpreting LCAs and using these to identify priorities. The ISO 30134-4:2017 standard for server energy efficiency and the NSF/ANSI Standard 426 -2017 on Environmental Leadership and Corporate Social Responsibility Assessment of Servers will be considered.

Development of criteria

For three areas, several criteria have been discussed:

Criteria Area 1: System Level Performance – presentation and discussion

1.1 Greenhouse gas emissions – Renewable Energy Factor (REF)

1.2 Greenhouse gas emissions – Facility Greenhouse Gas Inventory

Criteria Area 2: IT System Performance

2.1 IT energy efficiency – Server energy efficiency

The reference to US Energy Star, SEEM standards were questioned. JRC indicated it would have to consider the US Energy Star and Server Efficiency Rating Tool (SERT) that is proposed for use in the Ecodesign Implementing Measure.

2.2 IT utilisation – IT equipment utilisation

2.3 IT Equipment Operating Range – Temperature and Humidity Range

Although ASHRAE has developed criteria, these may not be suitable given how units are used in practice. The Eurovent Certified Performance programme to which reference is made is the IT Cooling Units programme (ITCU). ITCU is the programme that will replace the Close Control programme (CC) and it would be operational in the first quarter of 2018.

2.4 IT Material Efficiency – Design for durability, Design for disassembly and repair, Design for dismantling and recycling

2.5 IT Material Efficiency – Emissions of hazardous substances

2.6 IT Material Efficiency – End of life management

Criteria Area 3: M&E System Performance

In these criteria, there are many references towards fans:

3.1 Mechanical & Electrical systems energy efficiency – Power Utilisation Effectiveness (PUE)

3.2 Cooling – Reuse of waste heat

3.3 Cooling management – Operating conditions control

3.4 Cooling – Water discharge

Conclusions

Many information sources have not yet been analysed. This may provide for some delay in the project. However, the participants were reminded of the deadline for written comments on the first criteria proposals that should be posted on the BATIS system at the latest by Friday, 8 December 2017.  As in previous GPP project it is likely that the version established after 8 December could become the final one.

Recommended Actions

Manufacturers supplying equipment for data centres are encouraged to register for this study via BATIS. Even though Green Public Criteria have a voluntary character, it is possible that they will have an impact once known within the world of data centres.

Manufacturers may wish to contact Eurovent Certita Certification regarding the ITCU Eurovent Certified Performance programme.

Eurovent Market Intelligence has been monitoring the market for data centre cooling since 2011 and could be of interest to manufacturers.

If you have any queries about how to register or use BATIS please contact the helpdesk.
