Whole Building Design Guide Federal Green Construction Guide for Specifiers 09300 - 1 http://fedgreenspecs.wbdg.org 11/02/05 Tile This is a guidance document with sample specification language intended to be inserted into project specifications on this subject as appropriate to the agency's environmental goals. Certain provisions, where indicated, are required for U.S. federal agency projects. Sample specification language is numbered to clearly distinguish it from advisory or discussion material. Each sample is preceded by identification of the typical location in a specification section where it would appear using the SectionFormatTM of the Construction Specifications Institute. SECTION 09300 - TILE SPECIFIER NOTE: resource management: Mining raw materials (clay, silica, talc, feldspar, and limestone) for tile produces soil erosion, pollutant runoff, and habitat loss. Clay and sand are non-renewable although relatively abundant resources. Adhesives for setting tile and for latex mortar and grout are typically derived from petrochemicals. Standard portland cement mortar is composed of portland cement, sand, and water; refer to Section 03300 - Cast-In-Place Concrete for information regarding portland cement. Pigments include a variety of crystalline materials obtained from the calcining of oxides of metals such as cobalt, nickel, aluminum, and chromium. Manufacturing of ceramic tile is considered energy intensive; however, there have been some energy efficiency improvements in firing techniques in recent years. Manufacture generates particulate emissions. Most manufacturers reclaim their fired scrap materials. Tile containing recycled glass is available; generally the recycled glass is pre-consumer, industry waste such as windshield glass and waste from light bulb manufacture. Tile containing feldspar tailings, a by-product of feldspar refining process, is available. toxicity/IEQ: Tile (ceramic and quarry) is inert and cementitious mortar and grout is considered inert when cured. VOCs may be emitted from self-leveling cements and adhesives during the curing process. performance: Tile is extremely durable and requires little maintenance. Performance is comparable for green methods and standard methods. PART 1 - GENERAL 1.1 SUMMARY A. This Section includes: 1. Ceramic tile. 2. Porcelain tile. 3. Quarry tile. 1.2 SUBMITTALS A. Product data. Unless otherwise indicated, submit the following for each type of product provided under work of this Section: SPECIFIER NOTE: Green building rating systems often include credit for materials of recycled content. USGBC-LEED™ v2.2, for example, includes credit for materials with recycled content, calculated on the basis of pre-consumer and post-consumer percentage content, and it includes credit for use of salvaged/recovered materials. Green Globes US also provides points for reused building materials and components and for building materials with recycled content. 1. Recycled Content:Whole Building Design Guide Federal Green Construction Guide for Specifiers 09300 - 2 http://fedgreenspecs.wbdg.org 11/02/05 Tile a. Indicate recycled content; indicate percentage of pre-consumer and post-consumer recycled content per unit of product. b. Indicate relative dollar value of recycled content product to total dollar value of product included in project. c. If recycled content product is part of an assembly, indicate the percentage of recycled content product in the assembly by weight. d. If recycled content product is part of an assembly, indicate relative dollar value of recycled content product to total dollar value of assembly. SPECIFIER NOTE: Specifying local materials may help minimize transportation impacts; however it may not have a significant impact on reducing the overall embodied energy of a building material because of efficiencies of scale in some modes of transportation. Green building rating systems frequently include credit for local materials. Transportation impacts include: fossil fuel consumption, air pollution, and labor. USGBC-LEED™ v2.2 includes credits for materials extracted/harvested and manufactured within a 500 mile radius from the project site. Green Globes US also provides points for materials that are locally manufactured. 2. Local/Regional Materials: a. Sourcing location(s): Indicate location of extraction, harvesting, and recovery; indicate distance between extraction, harvesting, and recovery and the project site. b. Manufacturing location(s): Indicate location of manufacturing facility; indicate distance between manufacturing facility and the project site. c. Product Value: Indicate dollar value of product containing local/regional materials; include materials cost only. d. Product Component(s) Value: Where product components are sourced or manufactured in separate locations, provide location information for each component. Indicate the percentage by weight of each component per unit of product. SPECIFIER NOTE: Green building rating systems may include credit for low emitting materials. USGBC-LEED™ v2.2, for example, includes credits for low-emitting materials, including: adhesives and sealants, paints and coatings, carpets, and composite wood and agrifiber products. Under LEED™ v2.2, adhesives and sealants are to comply with California’s South Coast Air Quality Management District (SCAQMD) #1168; aerosol adhesives are to comply with Green Seal GS-36; interior architectural paints are to comply with Green Seal GS-11; anti-corrosive paints are to comply with Green Seal GS-03; clear wood finishes are to comply with SCAQMD #1113; carpet with the Carpet and Rug Institute (CRI) Green Label Plus; carpet cushion with CRI Green Label program; and, composite wood and agrifiber products are to contain no added urea-formaldehyde. As per USGBC published Credit Interpretations, the credits for low-emitting materials are directed towards interior, site-installed (i.e. not prefabricated) products. Verify project requirements for low VOC roofing products. Both the Adhesive and Sealant Council (ASC) and the SCAQMD have indicated that low VOC adhesives may have performance difficulties in extreme temperature and humidity conditions. Green Seal, an independent, non-profit organization, certifies low-emitting products using internationally recognized methods and procedures. Green Seal certification meets the criteria of ISO 14020 and 14024, the
