Armstrong Headquarters Achieves Platinum

The corporate headquarters for Armstrong World Industries, a flooring, ceiling, and cabinet manufacturer based in Lancaster, Pennsylvania, has earned a Platinum certification through LEED for Existing Buildings. The nine-year-old building, which achieved 64 points out of a possible 85, features onsite renewable power generation, waterless urinals, extensive daylighting, and native landscaping. The project earned an innovation point for the acoustical quality of its open-plan office spaces, which achieved an

articulation class—a measurement of reflected speech noise from one partitioned workspace to another—of 200 using Armstrong’s own Optima ceiling panels. The average articulation class for open-plan offices is 150–180, according to the company, and the best possible score is 250.
