As of January 1, 2008, NY updated its energy code to the 2004 IECC with NY amendments for residential buildings and to the 2003 IECC for commercial buildings, with ASHRAE 90.1-2004 expected to be adopted shortly after. Nevertheless, the code council is already considering adopting the 2006 IECC with enhancements such as lighting provisions on the residential side and 90.1-2007 provisions on the commercial side.
