Together with the Canadian Institute of Steel Construction (CISC), ArcelorMittal Dofasco has published an industry-average Type III Environmental Product Declaration (EPD) for cold formed steel panels and sections.

The EPD covers sheet steel construction products such as cladding, roofing, framing and deck products in compliance with the ISO 14040/44, ISO 14025 and ISO 21930 standards. It will help our partners and customers obtain a LEED point for disclosure of the industry-average Type III EPD document, and is valued as a half (1/2) product for purposes of credit achievement calculation. A summary of the CFS section and panel EPD can be found at this link on the CISC site, with the full version available upon request from the participating manufacturers.

The Corrugated Steel Pipe Institute has developed an EPD together with ArcelorMittal for corrugated steel conduit, and is available at this link. This industry-average EPD is also valued as half (1/2) a product for purposes of credit achievement calculation.

With the launch of XCarb^TM, ArcelorMittal Dofasco has published following EPDs to highlight the benefits of recycled and renewably produced steel:

XCarb EPD for Cold Formed Sections

XCarb EPD for Corrugated Steel Pipe

XCarb EPD for Hollow Structural Sections

XCarb EPD for Steel Cladding and Roofing

XCarb EPD for Steel Deck

ArcelorMittal products can assist in obtaining the following two points under the sourcing of raw materials credit category.

Point 1: The ArcelorMittal North American corporate sustainability reports are available at the following link. The reports include information on the environmental impacts of our mining operations and activities associated with our products supply chain. It was completed in accordance to the Global Reporting Initiative (GRI) framework. The report is valued as one whole product for credit achievement calculation.

Point 2: Recycled content. Our Recycled content letter is available at the following link. LEED recycled content is calculated as the sum of post-consumer recycled content plus one-half the pre-consumer recycled content, based on cost.

Steel is a highly engineered product and due to off-site fabrication, ArcelorMittal steel products do not generate a large volume of construction waste. Steel is the most recycled material on the planet. Any steel retrieved from demolition can be easily recycled , greatly assisting in obtaining the credits below. Up to two points can be obtained by diverting or reducing construction and demolition waste:

Option 1 – Diversion

• (1 point) Divert at least 50% of the total construction and demolition material; diverted materials must include at least three material streams.
• (2 points) Divert at least 75% of the total construction and demolition material; diverted materials must include at least four material streams.

Option 2 – Reduction of total waste material

• (2 points) Do not generate more than 2.5 pounds of construction waste per square foot (12.2 kilograms of waste per square meter) of the building’s floor area

The intent of this credit is minimize effects on microclimates, human and wildlife habitats by reducing heat islands. ArcelorMittal high reflectance roof products can assist in obtaining this credit by choosing one of the following options:

Option 1 – Non-roof and roof (2 points)

The combination of Non-roof Measures, ArcelorMittal High Reflectance Roof Products and Vegetated roof comply with the following formula:

A summary of ArcelorMittal high reflectance roof products that will help qualify for this credit can be found at the following link.

Option 2 – parking under cover (1 point)

Place a minimum of 75% of parking spaces under cover. ArcelorMittal high reflectance roof products found at the following link with an initial SRI of at least 39 at installation qualify for this credit.
