October 19, 2010 — Knoll, Inc. (NYSE: KNL) today announced that the Company’s Reff Profiles™ and AustoStrada™ furniture for open plan workspaces and private offices have achieved BIFMA level™ 3 certification from Scientific Certification Systems (SCS). level™ 3 is the highest rating that a product can achieve under the Business and Institutional Furniture Manufacturer’s Association’s (BIFMA) furniture sustainability standard. Reff Profiles and AutoStrada are also GREENGUARD Indoor Air Quality Certified®.Designed by Brian Graham, Reff Profiles™ is a functional and aesthetic evolution of the popular Reff System, which is known for its breadth of easily reconfigured open and private office solutions and wood excellence. Reff Profiles extends this heritage with a more progressive, efficient architectural presence. Conceived with the private office in mind, Reff Profiles underscores the longstanding Reff benefits of refined wood detailing, planning flexibility and breadth of options. Reff Profiles, introduced at NeoCon 2010, is available for order entry.AutoStrada epitomizes modern architectural thinking, offering a distinct, singular aesthetic for collaborative, open plan and private office applications. Manufactured using clean technology, including water-based adhesives, powder coating on metal, powder coating on wood and UV-cured wood coating, all of which are virtually VOC-free, AutoStrada is available in FSC-certified composite wood, GREENGUARD Certified, and can help meet the U.S. Green Building Council LEED® requirements.

BIFMA has established level™ as a common framework against which to evaluate the environmental and social responsibility of a variety of products. level™ is part of BIFMA’s ongoing development of voluntary product and industry standards that support safe, healthy and sustainable workplaces. To achieve level™ certification, Knoll partners with Scientific Certification Systems (SCS), known for its integrity and scientific rigor.

In the BIFMA level certification process, a product, the organization and facilities that produced it are scored according to sustainability criteria in four areas: Materials; Energy and Atmosphere; Human and Ecosystem Health; and Social Responsibility.

“Knoll continues to take leadership steps toward sustainability,” said Stowe Hartridge-Beam, level program manager at Scientific Certification Systems. “Once again, Knoll’s level 3 certification reflects their achievements in waste and greenhouse gas emissions reduction, human and ecosystem health, and social responsibility.”

Antenna Workspaces™, Generation by Knoll® and Dividends Horizon® have previously achieved level™ 3 BIFMA Certification from the Scientific Certification Systems.

“Level certification highlights our long-standing commitment to third-party programs that provide independent verification of environmental standards. The BIFMA sustainability program reinforces our efforts to pioneer clean manufacturing policies that protect the biosphere and conserve natural resources,” said Lou Newett, Knoll Health and Safety Manager, who leads the Company’s environmental sustainability efforts.

Knoll focuses on three key environmental areas: climate change, third party certification and environmentally-friendly products and manufacturing processes. The Company has also certified products under the SMaRT© Consensus Sustainable Product Standard, achieving SMaRT certification for Generation by Knoll (Platinum); Life (Gold); Chadwick (Gold); Calibre (Gold); Moment (Gold); and Template (Gold). In addition, Knoll recently established FSC® (Forest Stewardship Council) certified wood as the standard for general open plan office systems, casegoods and tables, recognizing that sustainable wood harvesting can contribute to reversing environmental and social trends. (FSC is the international standard setting body for defining and measuring a well managed forest and providing traceability through chain-of-custody certification.)

Knoll operates 10 LEED® certified showrooms in North America, including its Platinum certified facility in Toronto. The Knoll East Greenville, PA Lubin manufacturing facility is LEED Gold certified under the Existing Building pilot program; it is also an OSHA VPP Star site.
