Dovetail Partners recently examined the available life cycle assessment for flooring products to help determine the eco–friendliness of floor types. The findings they just released provide a helpful guide on selecting green floor. The flooring report is based on data from the Building for Energy and Environmental Sustainability program of the National Institute of Standards and Technology.

(Mpls, MN) – A new report from Dovetail Partners, a Minneapolis–based non–profit, examines available life cycle assessment (LCA) data for alternative flooring products. The findings provide a useful guide for selecting green flooring materials.

The Building for Energy and Environmental Sustainability (BEES) program of the National Institute of Standards and Technology (NIST) is the most comprehensive source of LCA-based information for floor covering products. NIST product evaluations are comprehensive, and are reviewed by a Scientific Advisory Panel of the Environmental Protection Agency as well as a Stakeholder Panel.

"The BEES program currently offers life–cycle based comparisons of over two dozen floor covering products," says Dr. Jim Bowyer, lead–author of the report. He notes that products are evaluated based on twelve different potential environmental impacts, including impacts on human health, fossil fuel depletion, air pollution and smog, global warming, ecological toxicity, and habitat alteration.

In addition to the BEES data, the report also reviews flooring research completed in Europe and Canada, and several recent studies completed in the United States.

"Overall, our review found that floor coverings made from bio–based materials, such as wood and cork have substantially lower environmental impacts than vinyl, ceramic tile, and wool and nylon carpeting," says Kathryn Fernholz, Executive Director of Dovetail Partners.

There are some limitations to the available information. To date, for example, there has been no published life cycle assessment of bamboo flooring. Information on carpeting is also limited in that BEES focuses on floor coverings typically used in commercial building and institutions rather than those used in residential structures.

Unfortunately, the BEES database does not yet include information on such flooring options as hardwood or bamboo. "However," says Bowyer, "in those comparisons in which wood flooring products have been among the options considered, the wood flooring has generally been found to have the lowest environmental impact."

The full report is available at the Dovetail Partners website (www.dovetailinc.org) and includes the ranking of eleven alternative flooring products in terms of their environmental performance.
