EnCon United Announces Stresscon Project Earns LEED Platinum Designation

Denver, Colo. (January 10, 2014) ‐ The U.S. Department of Energy’s National Renewable Energy Laboratory’s (NREL) Energy Systems Integration Facility (ESIF) has earned a LEED® Platinum designation from the U.S Green Building Council (USGBS), which is a non‐profit dedicated to sustainable building design and construction. Located in Golden, Colo., the facility is the nation’s first to help public and private sector researchers with clean energy technologies, and the fifth NREL campus facility to earn the LEED Platinum designation.

The Energy Systems Integration Facility applied for and achieved all 56 LEED points submitted. Completed in 2013, the facility features sustainable design features and materials. The 182,500 square foot facility includes experimental laboratories, outdoor test beds, and a high‐performance data center designed to be one of the world’s most efficient data centers.

A collaborative design‐build team including JE Dunn Construction and SmithGroup JJR participated in creation of the 182,500 square foot facility. The team incorporated sustainable design practices throughout the entire build project using recycled materials, skylights, operable windows enabling cooling and ventilation, and solar powered fans.

Stresscon provided the high performance thermally efficient precast wall panels for the project. The 14 inch Thermomass® panels consist of 3 inches of exterior gray concrete, 3 inches of polyiso
Thermomass® insulation, and 8 inches of structural concrete. With edge to edge insulation, the wall panels achieve an R‐value of 20.55. The R‐value achieved helps provide ESIF with a 40 percent greater performance efficiency than the ASHRAE 90.1 building standards baseline building performance rating.

NREL is the U.S. Department of Energy’s primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by The Alliance for Sustainable Energy, LLC.
