On April 23, a bill was introduced in the New York State Assembly that would mandate updating the state building code to include the 2009 IECC and ASHRAE 90.1-2007 and achieving compliance in 90 percent of new and renovated building space by the end of 2016.
Local codes may differ from the state code as long as they are "not inconsistent" with the state code. Local codes may also be more stringent in energy efficiency.
***As of April 29, the bill has been assigned to the Assembly Committee on Energy. Public hearing schedules will also be posted here. No meetings of the Energy Committee are scheduled as of yet through June 15.
