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.
