Leed and FloorScore
The LEED certification of premises is based on an evaluation model defined by the not-for-profit Green Building Council, which also grants the certification. Premises are evaluated according to the environmental loads of its location, water usage, energy efficiency, use of materials and indoor conditions. LEED certification is granted by the U.S. Green Building Council (USGBC), an independent industry organization.
FloorScore is a comprehensive US certification system for floor coverings that is based on the LEED point system. Zero, Xpression, LifeLine products and Quartz/Hovi tiles have passed the FloorScore test for environmental approval. To be granted FloorScore certification a product must pass demanding emissions tests to ensure that the product does not release any compounds that are detrimental to the quality of indoor air. Regular factory audits are also required.
FloorScore certification is based on the LEED point system and is granted by the US Resilient Floor Covering Institute (RFCI).
