Product declaration quantifies life cycle environmental impacts of cold-formed steel studs, track
The Steel Recycling Institute (SRI), Pittsburgh, has released the first industrywide Environmental Product Declaration (EPD) for cold-formed steel studs and track manufactured in the United States and Canada. The EPD quantifies the “cradle-to-gate” life cycle environmental impacts of these products and can be used by architects and engineers to document these impacts, steel industry website Construction & Demolition Recycling reports.
The SRI is a trade association that promotes and sustains the recycling of all steel products and is a division of the Steel Market Development Institute (SMDI), a business unit of the American Iron and Steel Institute (AISI), based in Washington.
The EPD, based on a peer-reviewed life cycle assessment, also can help designers achieve the credits required for building certification within Leadership in Energy and Environmental Design (LEED) and other green building rating programs, the SRI says.
This is the first industrywide assessment of the life cycle environmental impacts of these commercial building products in North America, according to the association. Roll-formed from galvanized steel sheet into a variety of shapes, cold-formed steel studs and track are being used as the primary structural system for buildings up to nine stories in height and have been used for curtain walls and interior partitions for decades.
“Environmental impacts of materials are critical decision factors for architects, engineers and builders,” said Lawrence W. Kavanagh, president of SMDI. “With the construction industry moving to comprehensive assessments of a product’s entire life cycle, it’s important this EPD is now being added to the resources we and our partners have developed for our customers in the construction industry.”
While a core component of steel’s sustainability is its continuous recyclability, the SRI says, environmental implications of steel reuse, recovery and recycling are reported in a separate module in the EPD to give users the ability to factor in their own end-of-life assumptions.
The EPD is available for download at www.recycle-steel.org.
