The International Code Council will hold the first public meeting focused on developing a model green-construction code, outside of Chicago in Rosemont, Ill., on July 28-30. In launching the multiyear initiative to create the International Green Construction Code, ICC says it expects a final draft of the code to be available “as a resource document” in 2010. The code, to be written under the guidance of ICC’s Sustainable Building Technology Committee, will address design and performance of new and existing commercial buildings. The American Institute of Architects and the American Society of Testing and Materials are participating in the development.
