"It was important for the architect to achieve wide spans for the atrium, but still control heat gain. This was achieved utilizing steel-loaded, free-spanning curtain wall with horizontal and vertical sunshades." -- Marty Trainor, account executive, Trainor Glass Co.

The basics:

In July, BMW of North America LLC opened the $100 million addition to its Woodcliff Lake, N.J., headquarters. The new buildings house a national training center, Eastern sales region and U.S. engineering operations. The atrium curtain wall spans 26 feet between anchor points, with sunshades installed on its framing. Glazing for the project cost $2.2 million.

The players:

Architect, Hellmuth, Obata + Kassabaum Inc., St. Louis; general contractor, Terminal Construction Corp., Wood-Ridge, N.J.; glazing contractor, Trainor Glass Co., Alsip, Ill.; glass fabricator, Viracon, Owatonna, Minn.; curtain wall fabricator, Kawneer Co., Norcross, Ga.; and sunshade supplier, Intertec, division of Doralco, both of Alsip, Ill.
