Wausau Window and Wall Systems and Tubelite: Companies' Products Help Minnesota National Guard Training Facility Meet Security, Sustainability Goals


5/23/2016

Wausau, Wis. — The Minnesota National Guard’s new 64,000-square-foot, $17 million Arden Hills Army Training Site (AHATS) readiness center earned LEED Silver certification from the U.S. Green Building Council. Contributing to its sustainability and security goals, the project (see photo) features Wausau Window and Wall Systems' blast hazard-mitigating curtainwall and window systems, plus Tubelite Inc.’s thermal entrance systems.

AHATS previously was known as the Twin Cities Army Ammunition Plant (TCAAP). More than 16.5 billion rounds of small-arms ammunition were produced here for World War II, the Korean War, and Vietnam conflict. The TCAAP was placed on the Federal National Priorities (Superfund) list in 1983. Since that time, extensive environmental investigation and remediation has occurred, including the excavation of about 94,000 cubic yards of soil and the removal of 200,000 pounds of volatile organic compounds (VOCs). 

Today, the improved site and new facility act as the public interface for the AHATS complex. It houses two units of the 834th Aviation Support Battalion, which specializes in maintaining Blackhawk and Chinook helicopters. Architects at Burns & McDonnell found inspiration in the helicopter motor and blades for the aesthetic and functional design of AHATS. 

Opened in September 2015, construction of AHATS new readiness center was completed on time and within budget. Set on nearly 2,370 acres in the northern third of Arden Hills, Minn., AHATS offers expansive views of rolling landscape and native plants. The facility is sited in consideration of anti-terrorism/force protection setbacks and consolidates spaces to optimize energy use. With an east-west orientation, the building takes full advantage of southern daylight exposure, allowing unoccupied areas to power down during the workday.

“While blast hazard mitigation was the major requirement, we also contributed to the project’s green building goals with the daylight, views, and high thermal performance with Wausau’s window and curtainwall systems, as well as Tubelite’s entrance systems. To help meet LEED certification submission requirements, recycled aluminum content was quantified,” said Eric Breidel, Wausau’s architectural sales representative serving Minnesota.

Working closely with Wausau, Burns & McDonnell and LS Black Constructors, W.L. Hall Co. installed 9,000 square feet of Wausau’s 7250 Series SuperWall with 4250i-BHM INvent blast hazard-mitigating windows. To help ensure occupant safety, Wausau's BHM Series products are designed and/or tested for compliance with the General Services Administration and the Department of Defense requirements as applicable.

"As window and curtainwall encounter the extreme pressures released by an explosive mass, all elements of the assembly work together to withstand the blast load and dissipate its energy. Instead of the historical design practice of specifying thick windows with rigid frames, modern blast-mitigating assemblies are intended to be flexible, and absorb, rather than resist, blast energy,” Breidel said.

Viracon provided the laminated, insulated glass with Crystal Gray tint and low-e coating. Laminated glass is specified to mitigate such hazards as hurricanes or bomb blasts. High-performing glass, as part of Wausau’s SuperWall system, also helps achieve NFRC U-Factors as low as 0.35 BTU/hr-sqft-ºF with Frame Condensation Resistance Factor (CRFf) of 69 and higher.

The high thermal performance of Tubelite’s Therml=Block entrance systems also contribute to AHATS’ energy-efficient goals. The Therml=Block entrances are installed on the exterior and just inside, Tubelite’s medium stile Monumental Doors comprise the interior entrances. Tubelite’s doors’ durable tie-rod construction and heavy-duty hardware may be further reinforced with steel for maximum strength and dependability.

High-performance architectural finishes also enhance AHATS’ durability and reduce the need for maintenance. Linetec finished the recycled aluminum framing for both Wausau’s and Tubelite’s systems using Class I clear anodize. Linetec has pioneered industry-leading environmental innovations in anodize, which does not contain VOCs. 

Supporting the project’s LEED Silver criteria, AHATS’ entrance, curtainwall, and window systems’ finished, extruded aluminum frames contain recycled content averaging 70 percent or greater. At the end of their lifecycle on AHATS, the aluminum framing can be recycled.
