LEED Credits – MR4, MR6, MR7 and EQ4.4

The following can affect the above specs:

Presence or absence of added urea-formaldehyde;
Recycled post-industrial content
Recycled Wood – wood that is a by-product of other manufacturing processes, such as sawdust, veneer backer boards, and peeler cores, etc…
Reclaimed Wood – All manufactured wood products that are reused or remanufactured into new products. For example, Relaimed wood can be reused flooring or reclaimed from old construction – barns, textile mills, factories, beer casks, etc…

Final finish – low- or no-VOC (Volatile Organic Compounds); unfinished floors can also be site-finished with water-based top-coat urethane, or waxed/oiled, depending on final use.
Salvaged Industrial Forestry – percentages matter;
Rapidly-Renewable – Bamboo – It’s hard to beat a 5-year re-growth curve. Cork, as well, is rapidly renewable and does not kill the tree when harvested. Cork comes from the bark of the Cork Oak tree which grows on the Portuguese and Spanish coastlines. It’s harvested about every 7 – 9 years and one tree can be harvested over 20 times.
Non-wood – Bamboo, cork.
Salvaged Post-Agricultural – again, percentages of content apply;
Salvaged Logs – Waterway, Forest Deadwood, Urban Forest, Industrial Forest, Post-Agricultural.
Sustainable Forestry – Wood harvested from well-managed natural forests or plantations. FSC-Certified – either mixed sources or 100%.
Low-Energy – certain manufacturing facilities save energy various ways. The goal is to reduce their overall carbon footprint.

Consider, for example, LEED MR6. MR stands for Materials and Resources. This classification considers the following:
Use rapidly renewable materials and products for 2.5% of total value of all building materials and products used (based on cost)
Harvesting is to be within a 10-year cycle or shorter. For flooring, look into these:
bamboo flooring
cork flooring
linoleum flooring

Use minimum of 50% of wood materials and products certified in accordance with FSC (Forest Stewardship Council) Principles and Criteria for wood building components:
flooring and sub-flooring
wood doors
Based on Cost of FSC wood products compared to total wood material cost.
Contractor doesn’t need the FSC number, but the supplier does.

As you can see, there is a wealth of information regarding LEED specs. We can help guide you to the proper flooring choice to maximize your LEED compliance, and minimize your carbon footprint!
