6 ADDITIONAL ENVIRONMENTAL INFORMATION MBA Building Supplies manufactures light gauge metal framing products for use in both non-structural and load bearing applications. Steel framing is universally regarded for its recycled content composition, reclamation rate, and many other energy saving and environmental quality improving attributes. MBA supports the increasing demand for sustainable green buildings and recognizes the importance of steel framing towards reaching higher standards in environmentally and socially responsible construction. LEED v4 MR Credit: Construction and Demolition Waste Management MBA metal framing products are 100% recyclable. Credits are awarded based on recycling and salvage rates of construction and demolition materials. Retain waste hauling certificates for documentation of recycling rates. Additionally, MBA metal framing can be cut to exact standards during the manufacturing process, significantly limiting total construction waste LEED v4 MR Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials - Recycled Content The steel used by MBA in the manufacturing of light gauge metal framing is produced in one of two furnace types: Basic Oxygen Furnace (BOF) or Electric Arc Furnace (EAF). Each furnace type uses a different production method, resulting in different levels of recycled content. Individual manufacturer recycled content statistics are not applicable because of the open loop recycling capability that steel and iron industries enjoy, with available scrap typically going to the closest melting furnace. The Steel Recycling Institute has set the industry standard recycled content levels for steel originating in the BOF and EAF processes. MBA metal framing products originate from an indeterminable mix of steel from these two furnace types. Basic Oxygen Furnace (BOF) Electric Arc Furnace (EAF) Total Recycled Content 32.7% Total Recycled Content 93.3% Post-Consumer Recycled Content 25.5% Post- Consumer Recycled Content 56.9% Post-Industrial Recycled Content 6.8% Post-Industrial Recycled Content 31.4% LEED v4 MR Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials - Regional Materials The light gauge metal framing products provided by MBA for project sites are manufactured in multiple facilities throughout the United States. To qualify for this credit, MBA s facilities must be within 100 miles of the project site. Additionally, the extraction point of the steel provided for the job site must also be within a 100 mile radius of the sourced location SCSglobalServices.com 6

7 LIFE CYCLE ASSESSMENT STAGES AND REPORTED INFORMATION The following life cycle stages are included: raw material extraction and steel production, transport to manufacturer, manufacture of light gauge steel framing, and benefits and loads beyond the system boundary (reported in Module D). The EPD does not cover life cycle stages for product use, building operation, and product disposal. Since this EPD does not include product use, the reference service life (RSL) is not specified. Module D represents the potential avoided production of primary steel as a result of the net steel scrap produced across the product life cycle. The Module D calculation accounts for all steel scrap material flows entering or recovered from the product system, including steel recovered at end-of-life, as well as the steel scrap generated during stud and track manufacture. To calculate the potential avoided burden resulting from the generation of steel scrap, a dataset representing steel scrap was used. These data were calculated based upon the methodology in the World Steel Association LCA report, Appendix 10 (2011). The potential avoided burden per kilogram of product for a specific inventory flow, ABFLOW, was assessed using Equation 1 AB FLOW = (RR-S) + Scrap FLOW Equation 1. The equation used to calculate AB FLOW, the potential avoided burden credit for a specific inventory flow per kilogram of product (LGS framing and accessories). RR is the recovery rate per kilogram of steel product; S is the amount of scrap used in the steelmaking process per kilogram of steel product; Scrap FLOW is the inventory flow per kilogram of steel scrap. The total steel scrap recovery rates, and steel scrap inputs, per kilogram of product, are summarized in Table 4 for each LGS framing product assessed at each manufacturing facility location.

10 Disclaimer This Environmental Product Declaration (EPD) conforms to ISO 14025, 14040, ISO 14044, and ISO Scope of Results Reported: The PCR requires the reporting of a limited set of LCA metrics; therefore, there may be relevant environmental impacts beyond those disclosed by this EPD. The EPD does not indicate that any environmental or social performance benchmarks are met nor thresholds exceeded. Accuracy of Results: This EPD has been developed in accordance with the PCR applicable for the identified product following the principles, requirements and guidelines of the ISO 14040, ISO 14044, ISO and ISO standards. The results in this EPD are estimations of potential impacts. The accuracy of results in different EPDs may vary as a result of value choices, background data assumptions and quality of data collected. Comparability: EPDs are not comparative assertions and are either not comparable or have limited comparability when they cover different life cycle stages, are based on different product category rules or are missing relevant environmental impacts. Such comparisons can be inaccurate, and could lead to the erroneous selection of materials or products which are higher-impact, at least in some impact categories. Any comparison of EPDs shall be subject to the requirements of ISO For comparison of EPDs which report different module scopes, such that one EPD includes Module D and the other does not, the comparison shall only be made on the basis of Modules A1, A2, and A3. Additionally, when Module D is included in the EPDs being compared, all EPDs must use the same methodology for calculation of Module D values. Interpreting the Results in Module D: The values in Module D include a recognition of the benefits or impacts related to steel recycling which occur at the end of the product s service life. The rate of steel recycling and related processes will evolve over time. The results included in Module D attempt to capture future benefits, or impacts, but are based on a methodology that uses current industry-average data reflecting current processes. SUPPORTING TECHNICAL INFORMATION Allocation: The LCA followed the allocation guidelines of ISO and the PCR. Co-products from steelmaking were allocated using system expansion, as described in the World Steel Association LCA Methodology Report (2011). Net steel scrap, accounting for scrap input to the product system and scrap generated from product manufacturers and at end-of-life, is modeled as a potential avoided burden and is reported as Module D. Limitations: Data was sought from a North American steel mill, but was unavailable. A representative dataset for EAF steelmaking in Europe was used, and adapted for the LCA through use of a US regional electricity grid. The production of steel has an important contribution to results, and this is a study limitation. A portion of the coated steel coil is purchased through steel brokers, and the origin of the steel is unknown. A dataset from the World Steel Association for North American hot-dip galvanized steel was used in the LCA to represent steel purchased through brokers SCSglobalServices.com 10

11 MBA provides LGS framing and accessories with a variety of metallic coating options, including: hot-dip galvanized, galfan, galvannealed, galvalume, and acryzinc. Data were not available for all metallic coating options and the coating was modeled using hot dip galvanization as a surrogate process. Data Sources The life cycle inventory (LCI) analysis was conducted using SimaPro 8.1 software, using a mix primary and secondary data sources, summarized in Table 7. These inventory data sources were used to create results for each inventory flow relative to the declared unit of one metric ton. Table 7. Data sources used for the LCA.

12 Table 8. Data quality assessment of Life Cycle Inventory. Data Quality Parameter Time-Related Coverage: Age of data and the minimum length of time over which data is collected Geographical Coverage: Geographical area from which data for unit processes is collected to satisfy the goal of the study Technology Coverage: Specific technology or technology mix Precision: Measure of the variability of the data values for each data expressed Completeness: Percentage of flow that is measured or estimated Representativeness: Qualitative assessment of the degree to which the data set reflects the true population of interest. Consistency: Qualitative assessment of whether the study methodology is applied uniformly to the various components of the analysis. Reproducibility: Qualitative assessment of the extent to which information about the methodology and data values would allow an independent practitioner to reproduce the results reported in the study. Sources of the data: Description of all primary and secondary data sources. Uncertainty of the information: Uncertainty related to data, models, and assumptions Data Quality Discussion Manufacturer-supplied data (primary data) are based on 2014 & 2015 annual production. Representative datasets (secondary data) used for upstream and background processes are generally less than 10 years old (typically 2007 or more recent). All of the data used represented an average of at least one year s worth of data collection, and up to three years in some cases. The data used in the analysis provide the best possible representation available with current data. Actual processes for upstream operations are primarily North American. Surrogate data used in the assessment are representative of North American or European operations. Data representative of European operations are considered sufficiently similar to actual processes. For the most part, data are representative of the actual technologies used for processing, transportation, and manufacturing operations. Precision of results are not quantified due to a lack of data. Data collected for operations were typically averaged for one or more years and over multiple operations, which is expected to reduce the variability of results. The LCA model included all known mass and energy flows for production of the LGS framing products. In some instances, surrogate data used to represent upstream and downstream operations may be missing some data which is propagated in the model. No known processes or activities contributing to more than 1% of the total environmental impact for each indicator are excluded. In total, these missing data represent less than 5% of the mass or energy flows. Data used in the assessment represent typical or average processes as currently reported from multiple data sources, and are therefore generally representative of the range of actual processes and technologies for production of these materials. Considerable deviation may exist among actual processes on a site-specific basis; however, such a determination would require detailed data collection throughout the supply chain back to resource extraction. The consistency of the assessment is considered to be high. Data sources of similar quality and age are used; with a bias towards Ecoinvent data where available. Different portions of the product life cycle are equally considered; however, it must be noted that final disposition of the product is based on assumptions of current average practices in the United States. Based on the description of data and assumptions used, this assessment would be reproducible by other practitioners. All assumptions, models, and data sources are documented. Data representing energy use at the manufacturer s facilities represent an annual average and are considered of high quality due to the length of time over which these data are collected, as compared to a snapshot that may not accurately reflect fluctuations in production. For secondary LCI datasets Ecoinvent data are used. Uncertainty related to the product materials and packaging is low. Data for upstream operations relied upon use of existing representative datasets. These datasets contained relatively recent data (<10 years), but lacked geographical representativeness. Uncertainty related to the impact assessment methods used in the study are high. The impact assessment method required by the PCR includes impact potentials, which lack characterization of providing and receiving environments or tipping points SCSglobalServices.com 12
