FloorScore credit on wall applications

For ceilings: It is compatible and can work. For walls: Not so easy. The difference is: The emission rate (per hour and surface area) will lead to higher emission concentration because the surface area of walls relative to room air volume is higher than for floors. You will need to request evidence of compliance from the supplier, or from the certification organism and its testing lab. They should have that information and are the only sources whom you can ask.

Sounds good. In that case, please look at the test report data. Emissions data for flooring has to be multiplied with a factor of 2.5 to get the data for walls - if it is all the walls. For accent walls, if the typical surface area in a typical room is below or equal 0.4 m2/m3 (or in US units), then the FloorScore data are valid as such because these use that so-called loading factor of 0.4. If this loading factor is higher, then multiply the emissions data with the corresponding ratio. If it still complies with all limits of California CDPH v.1.1 protocol, then you are fine. You just might want to issue an explanatory statement for designers. Or, if you prefer a third-party statement, then just ask the lab for such a document.

Thanks Reinhard. I agree. Good advice as usual
