Salt Lake City's Public Safety Building Achieves LEED® Platinum Certification with the Help of Aluminum ExtrusionsWorking with and involving the extrusion supplier early was a key element to making Salt Lake City's milestone energy-efficient government building design a reality.![]() The building's glass façade was a central element of Salt Lake City-based GSBS Architect's design. The northwest-facing public "face" of the building features a serpentine glass curtainwall that slopes from one wing to the other. The design also called for the curtainwall to cant -- or angle -- in multiple directions. In addition, the glass exterior needed to meet seismic and ballistic requirements, as well as contribute to the building's LEED and net-zero energy objectives. To address the complexities of the project's design and engineering needs, general contractor Okland Construction and glazing contractor LCG Facades quickly involved Wausau in the project's discussion. ![]() "The care and precision needed to make this complex design a reality was incredible," said Gene Pagel, Wausau's vice president of engineering. "Every piece, dimension and angle of the 135 unique curtainwall units located at the center of this building is different. That meant each component of each trapezoidal unit required design engineering and 3-D layout, along with precise and unique machining, fabrication, glazing and even shipping provisions." For the Public Safety Building's lobby and main floors, LCG installed more than 32,000 square feet of Wausau's INvision™ Thermal Unitized Curtainwall INvision products combine the benefits of natural light and outside views with the recognized performance and recycled content that may aid buildings seeking LEED certification. The selected INvision systems incorporate polyamide thermal barriers that enhance system thermal performance, condensation resistance and energy efficiency. Maximizing performance, minimizing field labor and allowing designers to choose the ideal system depth, face width and thermal barrier, these unitized curtainwall systems are fabricated for quick, easy installation and are backed with a standard limited warranty of up to 10 years. The unitized systems' interlocking frame design accommodates seismic, live load and thermal building movements. Structural silicone glazing and sealing are completed in Wausau's LEED-Silver certified manufacturing center for quality assurance. ![]() "A complete daylighting system provides shading from direct sunlight, glare protection and daylight redirection," explains Wausau's government/military market manager, Tom Mifflin, LEED Green Associate. "Lighting accounts for 40% of the energy used in a typical commercial building. Properly executed, daylighting can reduce HVAC peak loads with corresponding reductions in mechanical equipment capacity and carbon footprint." Wausau's aluminum frames, light shelves and sun shades contain recycled content averaging 70% or greater. Linetec finished these aluminum components in "MC Plantinum" using a two-coat, 70% fluropolymer mica flake paint. As an environmentally conscious finisher, Linetec safely captures and destroys the VOCs present in liquid solvent-based paints at the factory before arrival on the building site. Wausau's finished products comply with indoor environmental quality credits for low-emitting materials with respect to LEED criteria. Viracon fabricated the high-efficiency, triple insulating glass used in the curtainwall and the low-e, insulated glass installed in the casement windows. Other elements contributing to Salt Lake City's net-zero and LEED-Platinum goals for the building include:
