Case Study :
National Renewable Energy Laboratory (NREL) Energy Systems Integration Facility (ESIF)

90,000ft²

The Energy Systems Integration Facility is a 90,000 square-foot research building that supports research on clean energy, grid integration, and high-performance computing. It includes a state-of-the-art data center, specialized laboratories, and support spaces designed to meet strict energy, reliability, and research requirements. The facility has a design-build value of $97 million and meets LEED Platinum performance goals.

Cator, Ruma, and Associates played a central role early in the project by developing the performance criteria that guided the design-build teams. The team defined the mechanical performance expectations, energy targets, laboratory program needs, and requirements for the high-performance computing environment. Over four months, CRA worked closely with NREL researchers to translate complex scientific needs into clear criteria for the RFP.

CRA assisted in evaluating system concepts, energy models, one-line diagrams, and load studies. As design progressed, the team reviewed the mechanical, electrical, and IT systems to verify alignment with the performance standards and program requirements.

During construction, CRA provided periodic onsite observations to confirm that equipment and systems were installed correctly and were on track to meet the required performance levels. The outcome is a world-class research facility shaped by clear criteria, close collaboration, and a commitment to high-energy performance.
