Rusty Lockers Kicked Out In Renovation

Self-leveling underlayment Durock EcoCap self-leveling underlayment is reported to reduce its carbon footprint by 50% and reduce embodied energy by 45% when compared to Portland cement-based or calcium aluminate cement-based underlayment products. The product’s lower surface pH enhances compatibility and durability of floor-covering adhesives. The underlayment can contribute to LEED credits and is fast drying and quick setting. It supports foot traffic within two hours, and most floor coverings can be installed after 16 hours.

Building’s Public Face Reflects Energy Aims Net-zero and LEED-Platinum certification drove the design of Salt Lake City’s Public Safety Building.

Salt Lake City’s Public Safety Building sets a new standard in creating a functional, energy-efficient government structure in stunning Modern architecture. It is the first public-safety building in the nation to be designed as a net-zero energy building, generating as much energy as it uses. It also is one of the first public-safety buildings designed to meet the U.S. Green Building Council’s, Washington, LEEDPlatinum certification criteria. The newly opened building features a unitized curtainwall, windows, light shelves, and sun shades manufactured by Wausau, WIbased Wausau Window and Wall Systems.

The $125-million, 335,000-sq.-ft. facility includes 172,000 sq. ft. of space on four levels above ground, and 143,000 sq. ft. of secure parking below grade. In addition to housing Salt Lake City’s police and fire departments, it functions as the primary disaster/emergency operations center for the area.

CANTED FAÇADE 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 to complementing the Modern style of architecture shared by many of downtown’s public-sector buildings, the Public Safety Building’s 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 Façade, both of Salt Lake City, quickly involved Wausau’s representatives in

the project’s discussion. “LCG Façade was brought in early in the design phase to answer GSBS Architect’s number-one question: ‘Can a curtainwall system segment and cant backward at 15 degrees and then change angle, while maintaining the cant through a reverse S curve?’” explained Ted Derby, business development manager at LCG Façade. “We thought with Wausau’s help, we could make it happen. As soon as we received a wire-frame 3-D model, we sent it to Wausau, and they came back with a conditional, but affirmative statement that they could make the design a reality. Shortly afterward, Wausau and LCG Façade entered into a agreement to work together on the project.”

Derby added that once the agreement was in place, Wausau’s engineers visited Utah to view the construction site and meet with GSBS Architects to ensure that the curtainwall and window system

Nearly two dozen casement windows were installed on the building’s upper floors to support the project’s goals for natural ventilation and a connection to the outdoors for occupants.

designs were in sync with GSBS’ architectural vision. Once confirmed, Wausau moved into the next phase: applications engineering, fabrication, and finishing of the curtainwall elements.

EACH PIECE, DIMENSION, ANGLE DIFFERENT “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 sq. ft. of Wausau’s INvision thermal unitized curtainwall, including 19,150 sq. ft. of 7250i-UW series and more than 13,000 sq. ft. of 6250i-HRX series. 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 curtainwalls are backed with a standard limited warranty of 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.

CONNECTION TO OUTDOORS Along with the curtainwall, LCG Façade installed nearly two dozen Wausau 4250-Z zero sightline casement windows on the building’s upper floors to support the project’s goals for natural ventilation and a connection to the outdoors for occupants. Also contributing to the Public Safety Building’s net-zero energy goals, Wausau engineered and installed Clear Story interior light shelves and sun shades to allow light to penetrate deep into the interior spaces.

“A complete daylighting system provides shading from direct sunlight, glare protection, and daylight redirection,” explained 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, Wausau, WI, finished these aluminum components in MC Platinum using a two-coat, 70% fluropolymer mica-flake paint. As an environmentally conscious finisher, Linetec captures and destroys the VOCs present in liquid solvent-based paints at the factory before arrival on a building site. Wausau’s finished products comply with indoor environmental quality credits for low-emitting materials with respect to LEED criteria.

Viracon, Owatonna, MN, fabricated the high-efficiency, triple insulating glass used in the curtainwall and the low-e, insulated glass installed in the casement windows. In some curtainwall units, three different thicknesses of glass were needed to provide the security required for the project.

Other design components and practices contributing to Salt Lake City’s net-zero and LEED-Platinum goals for the Public Safety Building include: • Controllable task lighting to complement daylighting • Interior building materials with low-VOC content for improved air quality • Photovoltaic panels within a glass awning that extends from the main entrance onto a newly created outdoor plaza, generating energy to power electrical outlets that are available for public use • Rooftop photovoltaic panels to produce power for the build
