In May, NRCA participated in the International Code Council's (ICC's) 2011 code development hearing, which is one of the final steps before ICC publishes the new International Green Construction Code (IGCC). I encourage you to become familiar with IGCC because it likely will affect building construction significantly, including roof system installation.
During the past two years, ICC has been developing IGCC, which is intended to overlay ICC's other model codes and provide minimum requirements for sustainable buildings' design, construction and operation.
IGCC's initial public draft, referred to as Public Version 1.0, was published in March 2010. After a public comment period during which more than 1,500 comments were received and considered, the current draft, Public Version 2.0 (PV2), was published in November 2010.
