With a mission to strengthen U.S. security, Lawrence Livermore National Laboratory (LLNL) in Livermore, Calif., is home to two of the world’s most powerful supercomputers. Though manufacturer requirements called for cooling-system piping to be stainless steel or copper, LLNL engineers wanted to avoid the introduction of welding fumes into the data-center environment.
Built in 1975, the Visual Arts Building had been the hub of cultural and intellectual life at Colorado State University in Fort Collins, Colo., for years. Within its industrial, art-strewn walls, however, was a dated mechanical system in need of updating.
Lifeline Data Centers of Indianapolis, builder and operator of commercial data centers, was planning the first phase of a new facility. It planned to use water-based cooling, but was concerned about the potential for pipe leakage. Seeing a demonstration of the heat-fusing of polypropylene-random pipe at Aquatherm’s booth during the 2009 International Air-Conditioning, Heating, Refrigerating Exposition in Chicago put those concerns to rest.
ASI/Southern Mechanical Inc. introduced to the hospital staff polypropylene-random (PP-R) pipe manufactured by Aquatherm Inc. PP-R pipe, which is electrolysis-resistant, corrosion-proof, chemically inert, and durable, has been used in more than 70 countries for nearly four decades.
During the fall of 2008, Jimmy Hughes, owner and president of Hughes Bro. Inc., was in the process of bidding a potable-water-piping job at a 65-room, four-story Comfort Suites hotel in Nashville, Tenn. With copper prices at an all-time high, he was looking for a more cost-effective alternative. It was at that time he learned of a solution that had been used successfully in other parts of the world for more than 30 years: Aquatherm Greenpipe. But it was not only Greenpipe's lower cost that caught Hughes' and the hotel owner's attention.
Data breaches and other cyber crime cost companies billions each year worldwide, and the damage to brand reputation can be incalculable. Since hackers look for weakly defended systems to attack, this paper presents 5 cybersecurity “best practices” to mitigate system vulnerabilities. Some are commonsense measures like effective password management; others involve securing open ports and other access points, software upgrades, user management, and vulnerability plans....More
A top priority for higher education institutions is to provide a competitive learning environment for their students. In order to succeed, they must address outdated, aging campus facilities. In these older buildings maintenance and operations costs are high, space utilization is inefficient and poorly managed, and current technology is lacking. This white paper explores four strategies for converting campus facilities into a network of smart buildings that address the needs of current and future students....More
