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.
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), 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.
