Calculating % of Finished Floor FloorScore Certified

Are you possibly confusing FSC with Floorscore? FSC is under the criteria of Materials and Resources Credit 7 (http://www.leeduser.com/credit/NC-2009/MRc7) This credit covers the Indoor Air Quality criteria of ALL flooring installed in the building.

The criteria for this credit is only relevant for new flooring - 100% of the new flooring must comply. The existing flooring is irrelevant for this credit.

I am not sure what form you are talking about, but this is an all or nothing credit. Please scroll to the top of this page and read the "Bird's Eye View" and go to http://www.usgbc.org/cert-guide for more information.

Oh, my apologies, I did not understand, but now the questions make a lot of sense.

Patricia - No one said it was mandatory. The forum is available for no charge but there is a lot more to LEEDuser than just the forum (this is considered a limited-access account). BTW - It's only $12.95 per month for full access - http://www.leeduser.com/select. It may be however that you have specific questions that can't be easily answered on the forum...

Here is the text (there is no calculation, all flooring must comply) Good luck. LOW-EMITTING MATERIALS: FLOORING SYSTEMS All flooring must comply with the following as applicable to the project scope (a small amount of non-compliant flooring may be used for specialty areas provided it does not exceed 5% of floor area): • All carpet installed in the building interior shall meet the testing and product requirements of the Carpet and Rug Institute’s Green Label Plus program. • All carpet cushion installed in the building interior shall meet the requirements of the Carpet and Rug Institute Green Label program. • All carpet adhesive shall meet the requirements of IEQ Credit 4.1: Adhesives and Sealants, which includes a volatile organic compound (VOC) limit of 50 g/L. • All hard surface flooring covered by the FloorScore standard must be certified as compliant with the standard (current as of the date of this rating system, or more stringent version) by an independent third-party.
