Smart Solutions Case Studies
Letsos Company and CFI Mechanical, both of Houston, TX, used Uponor PEX for two high school plumbing projects to save money for the school district while also realizing faster installation and cost savings over traditional approaches. CFI Mechanical estimated a 30-percent savings in cost and labor resulting from using smaller PEX piping (1″ and below).
Delta Electronics (Americas) originally specified a conventional radiant tubing heating and cooling system for its headquarters expansion in Fremont, CA, to help meet LEED® Platinum and net-zero energy building standards, but ACCO Engineered Systems suggested Uponor’s Radiant Rollout™ Mats for a faster, more efficient, consistent installation. ACCO crews installed 138,000′ of tubing with the Radiant Rollout Mats in five months—much faster than the time required for conventional PEX rails or tie-down methods.
For a record-setting continuous concrete pour, Couts Heating and Cooling, Inc. installed more than 20 miles of Uponor radiant tubing to create a thermal cooling system that would ensure the integrity of the concrete as it cured. Applying this new technique, Couts not only smoothed the way for this rapid, massive project, it also benefitted from the ease of installation. The PEX tubing’s “extreme flexibility made it fast and easy to install around the rebar in the base of the structure,” said Mike Martin, Couts piping department manager.
Describing the Circulating Air crew’s first experience using Uponor products, Job Foreman Matt Fitzgerald said, “We were truly amazed at how quickly and easily we installed the tubing for the radiant heating and cooling system.” The Los Angeles-based mechanical contractor’s four-man crew installed 16,000’ of Uponor’s Wirsbo hePEX™ tubing in a new research building on the campus of the University of California, Los Angeles (UCLA). Using the radiant heating and cooling system helped earn LEED® Gold status for the six-story, 100,000-square-foot Edie and Lew Wasserman Eye Research Center.
Metropolitan Mechanical Contractors (MMC) of Eden Prairie, MN, found that using Uponor’s AquaPEX® crosslinked polyethylene (PEX) piping for the risers and the unit piping in a new hotel saved crews about two to three days of installation per floor. On a 13-story project with 50 units per floor, that adds up to almost a month of installation time savings.
With an impossible deadline to meet, Trautman & Shreve needed an ultra-efficient tool to meet the twin performance criteria of energy efficiency and cost control for the new Research Support Facility (RSF) at the National Renewable Energy Laboratory (NREL) in Golden, CO. So they prefabricated 42 miles of Uponor’s cross-linked polyethylene (PEX-a) tubing into customized “radiant mats” and installed them in just two days, dramatically cutting both labor time and costs.
To help San Diego State University’s (SDSU’s) Associated Students reach its goal of making all its buildings LEED® certified by 2020, University Mechanical installed an Uponor in-slab radiant heating and cooling system in the new student union. Now, the three story Aztec Center is not only highly sustainable, it is also LEED Platinum certified.
