LEED requires you to select products that have undergone routine volatilization / dissipation assessment when selecting ground materials. The so-called conventional volatilization / dissipation assessment means that the floor material must be tested and confirmed to meet the standard according to the California Department of public health (CDPH) standard method or similar consistent standard method, using the applicable exposure environment mode. When choosing the floor materials, many people may not know whether the products have passed the test. The simpler way is to choose the certified products that have passed the CDPH test.
