38 How Does Ceramic Tile Contribute to the Environment? Recycled Material Content Environmental Air Quality Solid Waste Conservation Water Conservation Energy Conservation Life Cycle

39 Which Ceramic Tile Contributions Help Earn LEED Credits? Materials and Resource Credits (MR) More than 97% of ceramic manufactured products contain pre-consumer (post-industrial) recycled materials. Multiple manufacturing facilities in the United States give several manufacturers the opportunity to be closer to more projects than anyone. Manufacturers are investing in cardboard and shrink-wrap packaging materials which contain recycled materials, and all packaging can be recycled or reused, helping to minimize waste. Indoor Environmental Quality Credits (IEQ) Most tile glazes are water based and use minimal amounts of solvents. Once fired, the tile and glaze are completely fused and there is no possibility of emission of any volatile gasses. (VOC s).

40 ISO Document Environmental Labels and Declarations Pre-Consumer Material Material diverted from the waste stream during the manufacturing process. Excluded is reutilization of materials such as rework, regrind or scrap generated in a process and capable of being reclaimed within the same process that generated it. The term Pre-Consumer" used in the ISO document means the same thing as the term "Post-Industrial. Post-Consumer Material Waste material generated by households or by commercial, industrial and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose. i.e. aluminum beverage can.

41 LEED for New Construction Rating System V 2.2 MR Credit 4.1: Recycled Content: 10% (post-consumer + 1/2 pre-consumer) 1 Point Intent Increase demand for building products that incorporate recycled content materials, thereby reducing impacts resulting from extraction and processing of virgin materials. Requirements Use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (based on cost) of the total value of the materials in the project. The recycled content value of a material assembly shall be determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value. Mechanical, electrical and plumbing components and specialty items such as elevators shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3 7. Recycled content shall be defined in accordance with the International Organization of Standards document, ISO Environmental labels and declarations Self-declared environmental claims (Type II environmental labeling). Post-consumer material is defined as waste material generated by households or by commercial, industrial and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose. Pre-consumer material is defined as material diverted from the waste stream during the manufacturing process. Excluded is reutilization of materials such as rework, regrind or scrap generated in a process and capable of being reclaimed within the same process that generated it. Potential Technologies & Strategies Establish a project goal for recycled content materials and identify material suppliers that can achieve this goal. During construction, ensure that the specified recycled content materials are installed. Consider a range of environmental, economic and performance attributes when selecting products and materials.

42 LEED for New Construction Rating System V 2.2 MR Credit 4.2: Recycled Content: 20% (post-consumer + 1/2 pre-consumer)1 Point in addition to MR Credit 4.1 Intent Increase demand for building products that incorporate recycled content materials, thereby reducing the impacts resulting from extraction and processing of virgin materials. Requirements Use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes an additional 10% beyond MR Credit 4.1 (total of 20%, based on cost) of the total value of the materials in the project. The recycled content value of a material assembly shall be determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value. Mechanical, electrical and plumbing components and specialty items such as elevators shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3 7. Recycled content shall be defined in accordance with the International Organization of Standards document, ISO Environmental labels and declarations Self-declared environmental claims (Type II environmental labeling). Post-consumer material is defined as waste material generated by households or by commercial, industrial and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose.

Excluded is reutilization of materials such as rework, regrind or scrap generated in a process and capable of being reclaimed within the same process that generated it. Potential Technologies & Strategies Establish a project goal for recycled content materials and identify material suppliers that can achieve this goal. During construction, ensure that the specified recycled content materials are installed. Consider a range of environmental, economic and performance attributes when selecting products and materials.

43 MR Credit 5.1: Intent LEED for New Construction Rating System V 2.2 Regional Materials: 10% Extracted, Processed & Manufactured Regionally: 1 Point Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation. Requirements Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% (based on cost) of the total materials value. If only a fraction of a product or material is extracted/harvested/recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value. Mechanical, electrical and plumbing components and specialty items such as elevators and equipment shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3 7. Potential Technologies & Strategies Establish a project goal for locally sourced materials, and identify materials and material suppliers that can achieve this goal. During construction, ensure that the specified local materials are installed and quantify the total percentage of local materials installed. Consider a range of environmental, economic and performance attributes when selecting products and materials.

44 LEED for New Construction Rating System V 2.2 MR Credit 5.2: Intent Regional Materials: 20% Extracted, Processed & Manufactured Regionally: 1 Point in addition to MR Credit 5.1 Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation. Requirements Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for an additional 10% beyond MR Credit 5.1 (total of 20%, based on cost) of the total materials value. If only a fraction of the material is extracted/harvested/recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.
