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 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.
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.
The Energy Systems Integration Facility (ESIF) at the National Renewable Energy Laboratory (NREL) used an innovative performance based procurement technique to incorporate energy goals into a complex laboratory building including a super computer facility. The Request for Proposal was key to achieving the success. This document is provided as a sample template for other goal based procurements.
This case study highlights the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center.
