The National Institute of Standards and Technology notes that "steel has become one of the most reliable, most used and most important materials of the age." As an advanced engineered material, steel is the material of choice by engineers and architects because of its strong performance characteristics, reliability, versatility in design, consistency as a product and "green" profile.

Residential and Commercial Construction

AISI-generated building standards have been incorporated into the most recent editions of the International Building Code (IBC) and the International Residential Code (IRC) and are used throughout the world. Steel continues to provide a proven environmentally responsible solution for meeting green building requirements in sustainability standards such as the International Green Construction Code (IgCC), ASHRAE 189.1, the National Green Building Standard (ICC-700) and green building rating systems like the U.S. Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED).
