Lawrence Berkeley National Laboratory (Center of Expertise for Energy Efficiency in Data Centers) / U.S. DOE FEMP 2020

Data Center Master List of Energy Efficiency Measures, Version 2.0 (September 2020)

Compare the planned UPS module count and redundancy scheme against the load curve: check the per-unit load at day-one and at full build, and consider modular units or switching off surplus modules.

  • Variable-speed chillers usually peak at 60-80% of full load; constant-speed chillers peak at full load.

U.S. DOE Better Buildings / Lawrence Berkeley National Laboratory 2017

Data Center Metering and Resource Guide (February 2017)

At a stand-alone site, design meters that record energy (kWh) at the utility entrance and at the UPS output (or at panels serving only IT if there is no UPS); a UPS display that shows only power (kW) is not enough.

  • PUE Level 1 for a stand-alone data center is utility meter reading divided by UPS output energy (M1/M2).

GSA Commissioning Guide (September 2020)

Set up the commissioning plan at the start of a data center project: review the OPR and basis of design with the CxP and write measurable performance targets.

  • At 10 months into a 12-month warranty period the CxP, operations office and CMa review systems for warranty repairs.

Guidelines for Using Propylene Glycol-Based Heat Transfer Fluids in Single-Phase Cold Plate-Based Liquid Cooled Racks (OCP white paper)

Write the PG25 or PG55 choice into the fluid specification according to the freeze protection the climate needs, and record that keeping glycol above 25% by volume removes the need for biocide.

  • Maximum corrosion rates under ASTM D8040-17: copper 0.22 mpy (5 mg/coupon), brass 0.46 mpy (10 mg/coupon).

Leak Detection and Intervention, Revision 1.0 (OCP Advanced Cooling Solutions white paper)

Run a probability-and-impact leak risk analysis at project start, specify BSPP/O-ring joints for serviceable connections and check the O-ring compound against the coolant chemistry using the full wetted-materials list.

  • A UQD2 dry-break quick disconnect is specified to drip less than 0.063 cc when disconnected at 200 psi.

U.S. DOE FEMP 2010

Operations & Maintenance Best Practices: A Guide to Achieving Operational Efficiency, Release 3.0 (August 2010)

Choose maintenance strategy by equipment criticality: predictive for critical equipment with random failures, preventive for equipment subject to wear, reactive for small non-critical items; build a master equipment list and priority matrix.

  • Boiler combustion tuning and related O&M can yield fuel savings of 2% to 20%.
