For LEED v4, so long as the flooring is tested for TVOC under General Emissions Evaluation (CDPH 1.1), it appears to comply complies. It feels as if flooring under LEED v4 is less stringent than LEED v3, as there are no actual limits on the flooring materials.
Has flooring really gotten less stringent? If yes, is there a reason why LEED has undertaken the path of only testing TVOC under General Emissions Evaluation?
