The basics: In May 2009, a 2-year, $9 million renovation was completed at the Holiday Inn, Gaithersburg, Md. The renovation, part of the hotel chain’s worldwide campaign to re-launch its brand with a more contemporary image, included a complete upgrade of the hotel’s exterior with energy-efficient glazing systems. Energy modeling shows the curtain wall window system will result in a 12.4 percent utility cost reduction, qualifying the project to receive a Commercial Building Tax Deduction provided in the Emergency Economic Stabilization Act of 2008, according to a Rehau release.

The players:
glass manufacturer, PPG Industries, Pittsburgh; curtain wall system supplier, Rehau, Leesburg, Va.; glass fabricators, Hartung Glass Industries, Seattle, Vitro America, Memphis; system fabricator, Thermamax Windows, Sparks, Nev.; glazing contractor, Miller Bros. Inc., Marshall, Va.; general contractor, B.F. Saul Co., Bethesda, Md.; contractor for effacing work on exterior, Conewago Enterprises, Hanover, Pa.

The glass and systems:
PPG's Solarban 60 low-emissivity glass with tint, used in combination with the Rehau Polytec 50 hybrid curtain wall system. The system provides a 0.29 U-value, according to the Rehau release.
