Why Steel


LEED V4 - Environmental Product Declarations

Environmental Product Declarations for Fabricated Structural Steel

The structural steel industry actively supports the transparent reporting of environmental impacts associated with construction products.  Many rating systems (LEED V4), standards (ASHRAE 189.1) and green building codes (IgCC) require the submission of environmental product declarations (EPDs) for products delivered to the project site. These EPDs rely on the results of life-cycle assessments to provide information on a number of environmental impacts related to the manufacture of the product, including global warming potential, ozone depletion, acidification, eutrophication and ozone creation.

AISC has developed industry average EPDs for two products:

These EPDs, which cover the product life cycle from cradle to fabricator gate, satisfy the submission requirements for programs such as LEED and Green Globes. Based on the rules spelled out in the ISO standards relative to EPDs, they can only be used by firms who participated in the development of the EPD through membership in the producing organization.

For that reason, an EPD  can only be submitted for project credit by firms that were AISC members at the time of its development or who have subsequently joined AISC and submitted environmental impact data relative to their shop. They cannot be submitted for project credit by a fabricator who does not meet these qualifications. In addition, these EPDs can only be used for mill material produced in the United States.  For hot-rolled structural sections the EPD can only be used for domestic material produced by:

  • Nucor Corporation
  • Gerdau
  • Steel Dynamics, Inc.

For HSS, the EPD can only be used for material produced by:

  • Atlas Tube, Inc.
  • EXLTUBE
  • Hannibal Industries, Inc.
  • Indepencence Tube Corporation
  • Maruichi American Corporation
  • Maruichi Leavitt Pipe & Tube, LLC
  • Maruichi Oregon Steel Tube (MOST)
  • Searing Industries
  • Southland Tube, Inc.
  • Vest, Inc.

AISC member fabricators that are authorized to submit these EPDs in fulfillment of LEED project requirements include:
