Data center energy efficiency is derived from addressing hardware equipment and infrastructure. Less than half the power used by a typical data centers powers its information technology equipment. The other half goes to support infrastructure, including cooling systems, uninterruptible power supply inefficiencies, power distribution losses, and lighting.

The Huntington Veterans Administration Medical Center implemented a large retrofit of faucets and showerheads in its 1-South section, which contains offices, clinics, a surgery unit, patient rooms, and laboratories. Conducted in 2007, the retrofit was part of the medical center’s Green Environmental Management Service initiative. New 1.5 gallon per minute (gpm) laminar flow faucets replaced 178 outdated 2.5 gpm models. A laminar flow head delivers tiny side-by-side streams of water that provide a
continuous flow and maintain a low flow rate. Laminar faucets tend to have less splashing and lend a smooth feel to the water. The initiative also converted 33 showerheads from 2.2 gpm to 1.75 gpm models with flow restrictor style heads.
This case study describes the National Renewable Energy Laboratory's (NREL) data center as a showcase of energy efficiency. Most of what NREL has done can be replicated by clients; however, two design approaches are climate-dependent: near-full reliance on outside air for cooling, and photovoltaic arrays for power.
This publication details the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center.
This case study details the design and operations of the National Renewable Energy Laboratory (NREL) Research Support Facility data center and its contributions to energy efficiency.
This checklist packet is a team-focused guide to realizing energy savings in high-performance office buildings through carefully considered lighting and control design. The checklists should be distributed among the integrated project team, including the owner, lighting designer and engineer, commissioning agent, and facility manager, at the beginning of a project and referred to regularly during design meetings and drawing reviews.
Conventional information technology (IT) equipment and data center spaces can consume more than 100 times the energy of standard office spaces, so the potential for energy savings is huge. You can use this application guide to reduce your equipment energy consumption in any building with a data center, server closets, or other IT equipment (computers, printers, etc.). Some of these strategies are most effective at the beginning of the design process; others can be implemented at any time and be sequenced as part of the normal procurement and replacement schedule.
Commercial Building Partnerships project portrait describing the strategies and technologies used to save 40% over energy code requirements.
InterContinental Hotels Group (IHG) and its franchise partner B.F. Saul Company Hospitality Group (B.F. Saul Co.) partnered with the Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce energy consumption by at least 30% versus requirements set by Standard 90.1-2004 of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI), and the Illuminating Engineering Society of North America (IESNA) as part of DOE’s Commercial Building Partnerships (CBP) Program.
An energy-efficient data center includes targets for its power usage effectiveness (<1.2) and energy resource efficiency (< 0.9). It should be designed with hot isle–cold isle separation, use free cooling (economizer) and evaporative cooling when available, minimize fan energy, and use the most energy-efficient equipment possible.
