We are working on a LEED-CI project that has access to salvaged plywood. The wood is in good condition and would be a shame not to re-use. However, because the wood is old and we do not have access to clear manufacturer\'s data for the product, we cannot ensure that the product is free of added urea-formaldehyde. Given that salvaged wood is excluded from the Certified Wood credit, in order to encourage the sustainable practice of reusing old timber, we are wondering if we could also exclude salvaged composite wood products from the EQc4.4 credit requirements. While this particular project is a LEED-CI project, we feel that the same logic would apply to other ratings systems; thus we\'re also requesting clarification for LEED-NC and LEED-CS projects as well.
The project is inquiring about whether they may exclude reused plywood from EQ credit 4.4. If the product is known to be at least one year old at the time of occupancy, then it may be excluded from EQ credit 4.4 based on the assumption that the majority of urea formaldehyde will have already off-gassed. The project should be prepared to provide sufficient documentation demonstrating that the plywood is at least one year old at the time of occupancy. Applicable Internationally.
