Stadium Scores Touchdown with Double Wall

Pittsburgh, Pennsylvania

When 2006 Super Bowl Champions the Pittsburgh Steelers announced plans last March to expand their home, Heinz Field, to include additional luxury suites and seating, local fans really had something to cheer about. PSSI Stadium Corp., which manages the stadium, planned to add 20,000 square feet of enclosed club space extending across the north end zone. Plans called for the additional space to feature a sleek, industrial architecture look, with an exposed ceiling and spiral duct to create a feeling of spaciousness.

Because both the ceiling and duct system were to be painted flat black to match other elements of the décor, the job specifically called for insulated spiral duct, which would be easier to paint than pipe that had to be wrapped externally to provide needed insulation. MidStates Spiral distributors sold builders on Lindab Safe® Double Wall duct. It was ideal for this type of application, not only because the ductwork was to be exposed, but also because it had because it had to be painted.

The contractor began work on the project in early summer, installing some 1,200 linear ft. of the Lindab Safe Double Wall duct with 245 round fittings. The ductwork was connected to ten new stand-alone blower coiler units, which also were exposed as part of the architect’s design. The ductwork was completed in late August, and the new space was formally opened on September 7th, 2006, when the Steelers faced off with the Miami Dolphins.

“Everyone was very pleased with the way the project turned out,” said Heidi Edwards, the PSSI Stadium Corp. coordinator for the project. “The fans really enjoy the new space, and its open, modern look, and the exposed duct work and the comfort it provides obviously contributes to that.”

Airport Runway Expansion Receives Industrial Air System

Fort Lauderdale, Florida

Hollywood International Airport (FLL) in Broward County, Florida, is a major hub facility serving more than 23 million annual passengers and the general aviation community throughout South Florida. FLL encompasses 1,380 acres and has three runways. In 2003, the county began planning a facility expansion to meet increasing demands and to provide a better customer experience to the millions of travelers who use the airport. This plan, which became the Airport Expansion Program, covers a wide range of activities, including the extension of the southern runway, Runway 9R-27L, to accommodate larger commercial jet aircraft. In 2007, the Broward County Board of County Commissioners voted to extend this runway, and the Federal Aviation Administration authorized the runway expansion the following year.

In September 2011, Broward County named Parsons the construction project manager for the expansion of Runway 9R-27L. This expansion is critical to both the airport’s long-range program and the overall U.S. air traffic system. Fort Lauderdale’s Hollywood Runway Expansion incorporated large diameter and fully welded HVAC ductwork.

Chilled Beams for Architect’s Office

Portland, Oregon

After 50 years of business and educating customers on the benefits for sustainable buildings, ZGF Architects, LLP of Portland, Oregon designed their new home in a new 23-story downtown building. Located on SW Washington Street in Portland, this building hosts five underground parking levels, one retail level, four floors allocated to ZGF and 18 floors for apartment living.

Alan Gerencer, an Associate Partner with ZGF, and his team challenged themselves to design an office space that was as energy efficient as it was transparent. Energy and atmosphere are vital for LEED achievements. The building was designed with operable windows and spaces with passive chilled beams. Passive chilled beams are smaller, inconspicuous mechanical units. The beams have no moving parts and complement an effective energy efficient solution. They also play a strategic role in compensating the solar load from the 12-foot windows.

This project was the first time ZGF had utilized passive chilled beams in their plans. Linx Industries was chosen due to the architect’s preference and Lindab’s radiant capabilities. Scott Davey of Air Commodities called Lindab’s cooling beam product line a “hybrid”. Where other beams have 90-95% convection, Lindab sets themselves apart by being almost 50/50 radiant and convection. For ZGF, the choice was simple; Lindab passive chilled beams were the “best looking”. Lindab’s Carat passive chilled beams are an independent convection chilled beam. They can be exposed free hanging or installed above a perforated suspended ceiling. There are 242 passive beams installed in plain sight and yet are still inconspicuous. While on office tours, the beams often have to be pointed out. Chilled beams come in a variety of colors; however, white was used in the common office areas while black was chosen for the offices with wood panel ceilings.

With the help of Lindab’s chilled beams, ZGF can be proud to say they have a sustainable office and a “living laboratory” to demonstrate the benefits of energy efficiency and transparency to their clients.

Dust Collection at the Herald

Miami, Florida

The media company’s move is attributed to costs and logistics. The relocation from a downtown waterfront property to Doral, FL provides easier access to the Miami International Airport and a reduction of overhead — most notably the rent. The McClatchy Company, owners of the paper, committed to the Doral site in January 2012 but an HVAC supplier had not been selected until November. This left just 6 months to get operational before their current lease expired. With careful planning and attentive project management,

Linx Industries was able to meet the challenging delivery schedule in short order. Throughout the holiday season and into early 2013, the Miami Herald Media Company looked on as their future production and distribution facility was erected. The fast-tracked project required both single and double wall spiral duct, flat oval, and dust collection air systems. Represented by Environmental Air Products of Fort Lauderdale, FL, Linx’s HVAC products were selected because of the company’s commitment shipping agility and product offering.

Known for innovative solutions for the HVAC industry, Linx expanded its offering to include Linx’s dust collection systems in late 2012. Otherwise known as Transfer, the product line was essential in the construction of The Herald’s plant. Although the manufacturer had collaborated many times on dust collection, this order marks the first and largest of its kind. Vice president David Shaeffer feels the expansion to the Transfer line was critical in the company’s quest to be the preferred air distribution supplier in North America. He said, “Our capability to sell a complete HVAC package gives us the ability to deliver solid materials with impeccable service and a fair price.”

Linx was pleased to participate in the successful completion of the Miami Herald’s printing plant. The building three-story 119,000 ft2 building house three commercial printing presses capable of supporting The Herald, El Nuevo Herald and commercial printing partners for the communities in the greater Miami area. Together with the adjacent main office, leaders of the Miami Herald hope a modernized newsroom will enhance their multimedia operations and inspire continued growth.
