What should I consider in choosing the greenest flooring for my basement?

Asked by Barbara, New Jersey

In the lower level of our home that is being constructed, we are planning to use stained concrete for the flooring. I am wondering if there is anything special that we need to consider in order to qualify for LEED points for our flooring. We are trying to ensure that 90% of our total floor area is using EPP (environmentally preferable products) materials (e.g., cork, etc.). I know they use some sort of acid to perform the staining. Are there questions I need to ask my provider?

Your first step is to check the LEED for Homes Rating System for the requirements of each credit. For information on which materials qualify for LEED points, consider the Materials and Resources section of the LEED for Homes Rating System, especially Materials & Resources Credit 2: Environmentally Preferable Products.

A given product may earn your project a ½ point for recycled content, and another ½ point for being low-emitting. Most flooring products include a label stating the volatile organic compound (VOC) content of any adhesives or stains. If the product does not meet low-emission criteria, it may meet one of the other EPP criteria.

Flooring products such as cork can often receive credit for being made of a rapidly renewable material (½ point), and can receive an additional ½ point if EPPs cover 90% of your floor space. Additional half-points (up to 8 points total) are available for having 100% hard-surface flooring and for using local materials. Of course, your provider is always a great resource if you have questions that you cannot find answers to in the rating system or for questions about the application of a certain technique, system or material to the rating system criteria.
