“Zones on this project ranged anywhere from 48 to 250 feet long and up to 24 feet wide,” Barela explains. After mapping out all zones, Trautman & Shreve purchased Wirsbo hePEX™ tubing in standard 1,000- and 500-foot rolls, then using 3-foot plastic rails (with loops in 6- to 10-inch spacings to hold the pipe together in an even width), they prefabricated their own radiant mats. Working with local sales agents Tom Meek and Tobi Gibson from TM Sales in Arvada, Colo., Barela and superintendent Don Martinez devised a pre-fab plan for the radiant zones. “Working with Haselden Construction, we knew that the five days allocated to us were not enough time to build all the radiant heating and cooling zones. “The job schedule was critical on this project,” Barela says. Tony Barela, project manager for mechanical contractor Trautman & Shreve, needed an ultra-efficient tool to meet the twin performance criteria of energy efficiency and cost control. In recognition of Stantec’s engineering consulting work on RSF, the company received the prestigious Engineering Excellence Grand Award from the American Council of Engineering Companies in April. Thermal and energy modeling provided the information the design-build team needed to keep the design true to the project’s aggressive goals.” “Then we focused on making the engineered systems as efficient as possible. “Our goal was to maximize the passive performance of this facility,” says David Okada of Stantec in San Francisco. Haselden Design-Build Project Manager Philip Macey, AIA, LEED AP, helped the project team through critical design decisions based on information in the contractor’s cost model and the design team’s energy, daylighting, natural-ventilation and thermal-mass models. These savings, in turn, helped NREL meet its budgetary goals and tight construction schedule.Ĭentennial, Colo.-based Haselden Construction was the builder of the facility.
“It isn’t enough to be energy-efficient when commercially viable technology exists to make buildings energy-neutral.”Īmong the many groundbreaking innovations that made the facility possible was a new method for installing radiant heating and cooling systems: the Uponor Radiant Rollout™ Mat, which enabled mechanical contractor Trautman & Shreve to dramatically slash labor time and costs. “In designing and building the new facility, our aim was to move the needle in how America uses energy to heat and cool buildings,” NREL Senior Engineer Paul Torcellini says.
When it came time to build a $64 million, 220,000-square-foot Research Support Facility on the campus, NREL engineers looked to Uponor radiant heating and cooling to help meet their energy-neutral goals. The National Renewable Energy Laboratory (NREL) in Golden, Colo., is the nation’s only federal laboratory dedicated to the research, development, commercialization and deployment of renewable energy and energy-efficient technologies.
