How To Start
A Problem That You Can Fix
Data Center energy efficiency is derived from addressing
BOTH your hardware equipment AND your infrastructure.
Commit to Improved Design and Operations
Typically, a central cooling plant and air handlers are more efficient than distributed air conditioning units. Begin with an efficient water cooled variable speed chiller, add high efficiency air handlers, low-pressure drop components, and finish with an integrated control system that minimizes unnecessary dehumidification and simultaneous heating and cooling.
• Benchmark existing facilities
Use temperature resets to allow use of medium-temperature chilled water
(55 degrees Fahrenheit or higher). Warmer chilled water improves chiller plant efficiency and eliminates the need for the chiller during many hours of operation (tower cooling).
• Continuously monitor energy and environmental conditions
• Document design intent
Less than half the power used by a typical data centers powers its IT equipment. Where does the other half go? To support infrastructure including cooling systems, UPS inefficiencies, power distribution losses and lighting. Why does this matter?
• Introduce energy optimization early in the design process
• Use life-cycle total cost of ownership analysis
• By 2012, the power costs for the data center equipment over its useful life will exceed the cost of the original capital investment.
• Re-commission as a regular part of maintenance
• By 2020, the carbon footprint of data centers will exceed the airline industry • Empower IT and facilities staff to work together
