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.
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.
Bank of America partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to build a new bank branch in Punta Gorda, Florida, with a goal of being at least 50% below ASHRAE Standard 90.1-2004. The branch opened in October 2011 and achieved actual energy savings of 47%.
PNC Financial Services partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to retrofit its existing Singer Island, Florida, branch to reduce energy consumption by at least 30% versus ASHRAE Standard 90.1-2004. Construction was completed in January 2012.
A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.
Tower Companies, a DC based owner of large multi-tenant buildings and Better Buildings Challenge partner, engaged in an aggressive program to take measured data from their buildings and turn it into real energy savings. This case study, completed by Tower in partnership with the National Resources Defense Council (NRDC) describes outcomes at three properties. The case study was highlighted on a Better Buildings Webinar on February 5, 2014.
This video presentation highlights whole building design using a large office building located on the National Renewable Energy Laboratory's campus in Golden, CO as an example.
"Four years after full occupancy in 2007, the owner agreed to participate in a post-occupancy monitored evaluation of the dimmable lighting system to verify actual performance in the field. Annual lighting energy savings from daylighting, setpoint tuning and occupancy controls were determined."
