July average Power Usage Effectiveness (PUE): 1.47

Average Power Consumption:

• 400 kW IT = 67.8%
• 1 kW lighting = .1%
• 24.9 kW building and IT losses = 4.3%
• 165 kW cooling power = 27.8%

Data Center Efficiency Progress:

The DOE national average PUE for data centers is 1.75.  The 50B-1275 data center has evolved from an average PUE of 1.65 (calculated in 2009) to today’s 1.46.  Getting there, staying there, and further improving the PUE is an ongoing effort.

Key highlights for this month include:

• Updates were suspended the last two months due to sensor read out failures.  A water temperature sensor was replaced and an IT load electrical meter failed.  The meter sensor was replaced.
• New VFD software to automatically control air handler air flow has now gone through final testing by the vendor and the new software has been down loaded to our server.
• The hot gas pressure valves have been replaced in the two 15 ton air handlers and appear to be working correctly.
• During August we will be working with the vendor and EETD on the VFD drive testing plan.
