Whole Building Design Guide Federal Green Construction Guide for Specifiers 04200 - 1 http://fedgreenspecs.wbdg.org 11/02/05 Masonry 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 04200 - MASONRY SPECIFIER NOTE: resource management: Mining of clay, shale, soil, sand, limestone, and metal ores can produce soil erosion, pollutant runoff, and habitat loss. Clay masonry firing produces fluorine and chlorine emissions. Manufacturing waste is typically recycled in new units. Salvaged units are available in many communities. Industrial waste by-products can be used for aggregate in concrete block (although documenting this can be difficult) including: air cooled slag, cinders or bottom ash, ground waste glass and concrete, granulated slag, and expanded slag. Refer to Section 03300 - Concrete for information regarding concrete materials. toxicity/IEQ: Masonry is considered to be relatively inert. Refer to Section 03300 - Cast-In-Place Concrete for information regarding portland cement. VOCs may be emitted due to additives, sealers and coatings. Because oil is commonly added (and burned away) during the production of clay masonry, the manufacturer can use oil contaminated soil that is free from hazardous contaminates. Although radon has been associated with certain soils, bricks do not produce abnormal exposure to radon gas except in rare situations. performance: Performance is comparable for green methods and standard methods. Traditional masonry construction provides thermal mass and durable construction. Masonry construction, when roughly textured, ribbed or fluted, can help reduce noise by dispersing sound waves. Consider interlocking concrete masonry units for landscape retaining walls; interlocking concrete masonry units do not require mortar and are easy to disassemble and reuse. Masonry is reusable and easily recyclable. Light-weight concrete masonry units are available that have superior thermal and fire resistive properties. Segmental retaining walls and interlocking concrete pavement components for earth retention and pavement applications, that do not require the use of mortar are manufactured with similar environmental benefits as concrete masonry units. PART 1 - GENERAL 1.1 SUMMARY A. This Section includes: 1. Clay masonry. 2. Concrete masonry. 3. Mortar, grout, and masonry accessories. B. Related Sections: 1. Section 03400 – Precast Concrete: Autoclaved Aerated Concrete (AAC) Units. 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:Whole Building Design Guide Federal Green Construction Guide for Specifiers 04200 - 2 http://fedgreenspecs.wbdg.org 11/02/05 Masonry 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: 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. B. Submit environmental data in accordance with Table 1 of ASTM E2129 for products provided under work of this Section. C. Operating And Maintenance Manuals Submittals: SPECIFIER NOTE: The marking system indicated below is intended to provide assistance in identification of products for making subsequent decisions as to handling, recycling, or disposal. 1. Verify that plastic products to be incorporated into the Project are labeled in accordance with ASTM D1972. Where products are not labeled, provide product data indicating polymeric information in Operation and Maintenance Manual. a. Type 1: Polyethylene Terephthalate (PET, PETE). b. Type 2: High Density Polyethylene (HDPE). c. Type 3: Vinyl (Polyvinyl Chloride or PVC). d. Type 4: Low Density Polyethylene (LDPE). e. Type 5: Polypropylene (PP). f. Type 6: Polystyrene (PS). g.
