Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

The Energy Conservation Construction Code of New York State (ECCCNYS) requires that all government, commercial and residential buildings, including renovations involving building system replacement, must follow the 2009 IECC code. Historic buildings and buildings that do not use either electricity or fossil fuel for comfort conditioning are exempt from these requirements.

The NYS Department of State Division of Code Enforcement and Administration has the responsibility to administer, make amendments, and provide technical support in the form of interpretations and variances. Most recently, the State Fire Prevention and Building Code Council voted on April 1, 2010 to update the ECCCNYS. The updated code is based on the 2009 IECC and ASHRAE 90.1-2007, along with several NYS specific enhancements (the previous ECCCNYS was based on the 2004 IECC supplement and ASHRAE 90.1-2004).

Enforcement of the requirements rests on the governmental entity administering and enforcing the provisions of the Building Construction Code or the Fire Prevention and Building Construction Code applicable within the municipality.
