Home to some of the most powerful supercomputers in the world, Los Alamos National Laboratory’s secured supercomputing facility known as the Nicolas C. Metropolis Center for Modeling and Simulation or simply, the Strategic Computing Complex (SCC).  Bridgers & Paxton provided mechanical, electrical, plumbing & controls engineering for LANL’s Exascale Class Computer Cooling Equipment (ECCCE) project at the SCC.  Exascale Computing systems are essential to improving the National Nuclear Security Administration’s weapons design, stewardship and stockpile certification programs using modeling and simulations.

The team engineered a solution that makes the SCC building more efficient and enables at least two advanced technology computer systems (current Trinity supercomputer & future 2021 Crossroads Exascale-class computer) to be warm-water cooled at the same time. This power saving design allowed 6.8 MW of power to be used for the 1 Million CFM of air flow needed on the data center floor (in addition to the warm-water cooling) and for the cooling, power & lighting needs of the hundreds offices in the SCC building.

The ECCCE team successfully expanded the warm-water cooling systems in the basement of this high security facility that runs 24/7 in the middle of a National Laboratory. The building and site had limited space for the new infrastructure & equipment; the expansion was accomplished without disruptions to the SCC or the surrounding high security buildings.

The additional warm-water cooling improved the Power Usage Effectiveness (PUE) of the facility by at least 15%, thus reducing total electrical consumption that chilled-water cooling would require. Using the environmental advantages of the low-humidity and relatively cool environment of Los Alamos New Mexico; the design team was able to provide a total available cooling capacity of 33.2 MW and 22,760 GPM of warm-water cooling fluid with a yearly average PUE of 1.14. This innovative solution is anticipated to save $750,000 annually for the facility.

The ECCCE team distinguished itself by implementing techniques that continued to save schedule and cost throughout the project, culminating in 10 months of schedule reduction and $20 Million of cost savings against Total Project Cost.
