ASC facilities include both the necessary physical facilities and the operational support for reliable, cross-lab production computing and storage environments. Also included is the suite of user services needed for effective use of ASC tri-lab computing resources. The scope of facility operations at LLNL includes planning, integration and deployment, continuing product support, software license and maintenance fees, procurement of operational equipment and media, quality and reliability activities, and collaborations. Facility support covers physical space, power and other utility infrastructure, and local area network (LAN)/wide area network (WAN) networking for local and remote access, as well as requisite system administration, cyber-security, and operations services for ongoing support and addressing system issues.
Sited at Lawrence Livermore National Laboratory (LLNL), the dual-level modular Building 654 houses platforms acquired as part of the commodity technology systems (CTS-1) procurement. Constructed with economy and adaptability in mind, the building consists of a 6,000-square-foot machine floor flanked by support space. The design of the main computer structure is flexible to allow for possible expansion and to accommodate future computer technology advances in high performance computing (HPC).
B654 provides unclassified HPC system space suitable for supporting the National Nuclear Security Administration's (NNSA's) Advanced Simulation and Computing (ASC) Program, other related national security missions, and collaborations with academia. ASC is the simulation effort for NNSA's stockpile stewardship program to ensure the safety, security and effectiveness of the nation's nuclear deterrent without additional underground testing.

LLNL's world-class computing facility, LCC B453, was designed for multiple generations of supercomputers. The modern structure includes:
In 2010, LCC B453 received a Leadership in Energy and Environmental Design (LEED) gold level certification under the U.S. Green Building Council (USGBC) rating system. LEED is an internationally recognized green building certification system that provides third-party verification that a building or community was designed and built using strategies aimed at improving performance in energy savings, water efficiency, carbon dioxide emissions reduction as well as other factors.
