Library renovation with historic windows earns LEED
The basics: In May 2009, renovation was completed on Pittsburg (Kan.) State University’s Porter Hall, the original student library. Historical window systems were used to recreate the appearance of the original steel windows while featuring a thermally improved frame and insulating glass. The project received a Leadership in Energy and Environmental Design remodel certification from the U.S. Green Building Council. An interior trim system and extended exterior leg were used for exterior installation to protect the building interior.
