• Defining meaningful, user-centric models and metrics
• Promoting the adoption of energy efficient standards, processes, measurement methods and technologies
• Developing standards, measurement methods, processes and new technologies to improve performance against the defined metrics
The Green Grid has set out to develop a standard set of measurements to make it easier for an end-user to manage their facilities and thus achieve optimal energy efficiency within data centres around the world. The Green Grid, comprising of peers throughout the data centre and computing industries, seek to unite global industry efforts to standardise and agree on a common set of metrics, processes, methods and new technologies to further its common goal.
Two such matrices are the Power Usage Effectiveness (PUE) and Data centre infrastructure Efficiency (DCiE). The Green Grid is also developing a third matrix, Data Centre Productivity (DCP).
UK Grid made the decision to join the Green Grid to work with some of the industry leaders in developing the ultimate in energy efficient data centres, thus lowering operating costs and also reducing UK Grid's carbon footprint.
The Green Grid's advice to data centres is to constantly measure your PUE and UK Grid have followed this advice to the letter, enabling our PUE to be reduced from 1.5 to 1.35. UK Grid has a target PUE of 1.2 in some of our newer facilities utilising free-cooling technologies which we will see come online towards the end of 2010.
