L. FLOORING
L1. ENVIRONMENTALLY PREFERABLE FLOORING

CRITERIA FOR QUALIFICATION This measure is available for allocation (partial credit). Allocation should be calculated based on the total flooring installed in the home. Up to three points of credit may be given for complying with one or more of the following for a percentage of the floor area: ? ? ? ? Using FSC-certified wood flooring materials Using reclaimed or refurbished flooring materials Using rapidly renewable flooring materials with a renewal cycle of ten years or less Using flooring materials with recycled content. To quality for this measure, carpet must contain a minimum of 10% post-consumer recycled content or 20% post-industrial recycled content. All other flooring material must contain a minimum of 25% recycled content by volume or weight. Postindustrial (pre-consumer) recycled content is counted at half the rate of post-consumer recycled content. Using exposed concrete as the finished floor Using locally produced materials, where documented evidence exists that 90% of the weight or volume of the material is extracted, processed, or manufactured within 500 miles of the home. This does not apply to materials that are generally considered to be environmentally unpreferable in their extraction, manufacture, installation, use, or end of life. This does not apply to common materials that typically have always been local throughout the state, such as sand, cement, and aggregate. Build It Green will review the use of these criteria.

To achieve each point value, the materials must be used in at least the following amount of the floor area: ? ? ? 1 point for ? 25% of the floor area 2 points for ? 50% of the floor area 3 points for ? 75% of the floor area

For the purposes of this measure, the floor area is the total square footage of flooring, including stairs. Subfloor does not need to meet the standards of this measure. Any adhesives used in installing the flooring materials must meet the lower of these two benchmarks: ? ?
