We value the natural resources that we use to build our furniture, which is why we are committed to green building or being environmentally friendly wherever possible. We work with our clients to integrate environmental friendly practices in our work – without ever compromising quality.
LEED V4 And Architectural Millwork
Specifying the right materials can earn you credits for your building’s LEED certification and contribute to our project’s Green Building program. Credits can be earned in two categories: aterials and Resources, and Indoor Environmental Quality.
Materials and Resources
A. Sourcing of Raw Materials
1. First, look at the MR Credit 5.1. Any materials pu to 20% extracted, processed and manufactured regionally within 500 miles of the jobsite are eligible for the Regional Materials credit of 1 point. We are lucky here in the Mid-Atlantic with close proximity to all the Applalachian hardwoods such as cherry, walnut and oak. Specifying Appalachian hardwoods will earn you this credit.
2. Two credit points are available in sustained sourcing and leadership extraction practices if products costing a minimum of 25% of the total project cost are used. Under these categories, the Forest Stewardship Council (FSC) has become the gold standard for forest management. By providing a Chain of Custody certifiate, FSC-certified manterials will contribute toward the 25% threshold. The FSC also certifies veneers and imported lumber. Specifying FSC certificiation is the best way to get LEED credits. Salvaged wood also contributes to this threshold.
3. Bamboo veneer has become widespread in the panel products market because of its sustainability. It’s easy to find plantation-grown bamboo with different grains and colors used in a variety of products.
4. Engineered and reconstituted wood veneers combine tradition and technology, having been manufactured from rapidly renewable trees in managed forests. Many are available in quarter and flat cut, and in both domestic and exotic species, providing an accurate appearance of color and grain as the natural wood. Cost effective and sustainable, FSC-certified species can be selected.
5. Choosing rapidly renewable materials also gain credit in the sustainable sourcing category. Sourghum (Kirei board) and wehat straw are two materials available in panel products. Along with MDF (high recycled content), these panels conserve wood by instead using an agricultural waste product. This kind of low carbon footprint is exactly what the Green Building Council is looking for.
6. Solid surface and engineered quarts products also help in the LEED point system. Most solid surface products have up to 20% post-consumer recycled content and engineered quartz can have up to 50% pre-consumer recycled glass. Either of these is worth 1 point under MR Credit 4.1 and 4.2. Check with the manufacturer for exact specifications.
B. Material Ingredients
For panel products, choose “no added urea formaldehyde” (NAUF) substrates and adhesives. Polyvinyl acetate (PVA) is the preferred adhesive for veneers as it is not considered to be tocis, even by chemically sensitive people. For fire-rated panels, use high borate content flakeboard. The manufacturing process using these chemicals has the least environmental impact, according to the EPA. These fire-rate panels have the added benefit of being up to 100% pre-consuer recycled content, which is the industry standard. There are several brand names on the market.
Indoor Environmental Quality
A. The products you choose also can earn points in this category. LEED V4 awards 1 point if the volatile organic compound (VOC) content of adhesives is less than the current limit specified in SCAQMD Rule #1168 and 1 point if the engineered wood and agri-fiber products contain no added urea-formaldehyde (NAUF) resins.
B. Low-Emitting Materials
Choose low or no VOC adhesives and NAUF panel products with phenol-formaldehyde or MDI as binders. Pheol-formaldehyde is must less toxic that urea formaldehyde. Methylene diphenyl diisocyanate (MDI) as a binder has no emissions. Both binders are availabe in MDF and flakeboard panel substrates. Soy-based binders are a new alternative resin technology based on a renewable resource (soy flour). It is being used as a binder in hardwood plywood panels and is being tested for use in other composite wood products. C. Off Gassing – Specify that all wood finishes must be allowed to off gas for three days before delivery to the jobsite. All off gassing of solvent-based and water-borne wood finishes is 99.9% complete after 72 hours.
