2 LEED 2009 International Program - Global Alternative Compliance Paths (ACP) LEED INTERNATIONAL-NC & CS 2009 As interest in the LEED rating system grew, the need to accommodate a growing number of international projects became more apparent. In an effort to make achieving LEED certification more accessible to projects worldwide, the U.S. Green Building Counsil (USGBC) has developed a series of Alternative Compliance Paths (ACPs) for projects outside the U.S. These ACPs have been developed with guidance from international green building experts and volunteers, and fully retain the integrity of LEED. The ACPs additional options are substitute credit and prerequisite requirements that establish a new and different way to demonstrate compliance with the stated intent of a credit or prerequisite. Synthetic Leaves Bora Bora and Aloha synthetic leaves were especially designed to be laid directly on a roofing frame with a patented railing system. These two leaf types offer two distinct technical advantages: full and effective exterior coverage in any weather, plus an exposed underside providing a more traditional aesthetic from the inside that proves popular in many countries. These roofing products provide exceptional storm-resistance and windresistance. A fire-retardant option is also available for both of these synthetic leaf products.

The recycled content value of a material assembly is determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value INTERNATINAL may contribute to this credit. The recycled content percentages may vary depending on the choice of the product s components and the suppliers. The synthetic leaves contain 15% preconsumer recycled content. (excluding internal waste). However, they don t contain any post-consumer recycled content. MR 5 Regional Material 1-2 points Use building materials or products that have been extracted, harvested or recovered as well as manufactured, within 500 miles (800 km) of the project site for a minimum of 10% or 20%, based on cost, of the total materials value. If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) must contribute to the regional value. The minimum percentage of regional materials is 10% (1 point) or 20% (2 points). : Use building materials or products that have been extracted, harvested or recovered as well as manufactured, within regional distances of the project site for a minimum of 10% (1 point) or 20% (2 points), based on cost, of the total materials value. If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) must contribute to the regional value. Regional distances are defined by the following options: The product from PALMEX INTERNATIONAL may contribute to this credit since 15% of the synthetic leaves is extracted, collected, treated and recovered within a 125 km radius of the final place of manufacturing (transported by truck). PALMEX INTERNATIONAL can rapidly provide all the information concerning the extraction, collection, treatment and manufacturing sites for all its products. The percentage calculation was performed by considering the requirements of Credit MR 5 and the maximum distance radius (which depends on the means of transportation used). This product s final place of manufacturing is located in Saint-Sauveur -des-monts, Quebec, Canada (J0R 1R7). The origin of the main components and the mean of transportation used must be validated for every project. Option 1: Within a radius of 500 miles (800 kilometers) from the project site Option 2: For building materials or products shipped in part by rail or water, the total distance to the project shall be determined by weighted average, whereby the portion of the distance transported by rail is divided by 3, the portion of the distance transported by inland waterways is divided by 2, the portion of the distance transported by sea is divided by 15, and added to the portion of the distance transported by any other means other than by rail, inland waterways, sea, or road, provided the total weighted average distance does not exceed 500 miles (800 kilometers) PAGE 5
