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.
This case study describes a successful zero energy school project in Utah.
On the night of May 4, 2007 an EF5 tornado 1.7 miles wide ravaged Greensburg, Kansas, destroying 95% of the city's homes and businesses. In the wake of the disaster, it became apparent that changes would need to occur to sustain the town for future generations. The Greensburg School District selected BNIM Architects to provide comprehensive design services for new school facilities.
In direct alignment with the town's Sustainable Comprehensive Master Plan, the USD decided to rebuild to LEED Platinum. This decision led the way for the city, which later mandated that all public buildings attain a Platinum rating. This K–12 facility combines the resources of three rural community school districts into a single facility, thereby right-sizing at a regional scale.
The Sacred Heart Academy Library is part of the Sacred Heart School's Lower and Middle School campus. The library is intended as an educational demonstration of the school's goal "to teach students to be stewards of the earth's resources." The library has achieved zero energy while meeting a very modest construction budget - in fact, all Zero Energy features, including photovoltaic panels, were included within the already established budget.
This case study highlights the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center.
