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.
When fully utilized, Building Management Systems (BMS) offer facility managers many advantages. Harnessing building data to help correct root-cause energy inefficiencies is one area that is increasingly important yet challenging. This paper shows how leveraging BMS data through building data analytics software and combining it with expert engineering services creates actionable intelligence that can reduce HVAC energy costs by up to 30%....More
Though not required until December, 2022, the new UL 60335-2-40 standard is currently active for matched and packaged air conditioners/heat pumps (no standalone systems), liquid chillers and hydronic fan coil units, hot water heat pumps, dehumidifiers and supplemental heaters (designed as part of an appliance package).
A lot of leading building automations systems (BAS) are touted as being open. But what does that really mean? And does being open mean that building owners and operators are getting the most out of their BAS investments?
During this webinar, Johnson Controls BAS experts will examine the definition of openness and advise on what to look for from a BAS provider when secure interoperability and ease of integration is paramount. Because a unified intelligent infrastructure provides better interoperability so businesses run more efficiently....More
