ENERGY STAR for Data Centers
ENERGY STAR Program
1992 voluntary labeling program to identify/promote EE products, i.e., computers and monitors.
ENERGY STAR label now many additional products, new homes, buildings & plants
Saved businesses, consumers, organizations $18 B in 2010
And prevented 170 MMt GHG
ENERGY STAR for Data CentersData Centers:
Spaces specifically designed, equipped to meet needs of high density computing equipment such as server racks for data storage, processing.
Typically require dedicated uninterruptible power supplies, cooling systems.
Functions may include traditional enterprise services, on-demand enterprise services, high performance computing, internet facilities, and/or hosting facilities.
Often free standing, mission critical computing centers.
Data center within larger building, usually has own power, cooling system.
Not represent server closet or computer training area.
ENERGY STAR for Data CentersStand alone data centers, buildings housing large data centers can now
earn ENERGY STAR label- BNY Mellon NPPC, Freeport, NC- NetApp Global Dynamics Lab, RTP, NC
Data Centers in nearly every economic sector
Use 1.5% U.S. energy, $4.5B, double next 5 years
Improve energy efficiency (EE) 10%, power 350K homes, save $450M/yr

Peers information based on Energy Consumption Surveys NetApp Global Dynamics Lab, RTP, NC
Rating of 75- performs better than 75% of peers- eligible for ENERGY STAR label

Guiding Principles for Energy Efficiency
Power Usage Effectiveness (PUE) – EE MetricsPUE = total data center energy/IT energy consumption
When calculating PUE, IT energy consumption should, at minimum,measured at output of uninterruptible power supply (UPS).
- Install meter if needed at UPS (A).
- Sub-meter non-IT load (B)supported by UPS if > 10% total.
- Future use PDU input (C).
Guiding Principles for Energy Efficiency
TOTAL ENERGY USE IN PUE
Dedicated data center: all energy sources at point ofutility handoff to data center owner or operator.
Data center, mixed-use building: all energy required to
operate data center, should include IT energy, cooling,lighting, support infrastructure for data center
operationsNote: In Portfolio Manager, must enter other spaces
(e.g. office) and provide all energy for whole building
