New York DOE Status of State Energy Codes

Residential

Commercial

The state energy code requires that all new commercial and residential buildings, manufactured housing not required to comply with the U.S. Department of Housing and Urban Development (HUD) requirements, and buildings undergoing substantial rehabilitation must follow the code. Historic buildings and buildings that do not use either electricity or fossil fuel for comfort conditioning are exempt from these requirements.

Requirements for commercial/residential buildings vary based on the location of the buildings within the state and the type of fuel used to heat the buildings. For example, residential buildings that are electrically heated are required to have higher insulation values.

Effective January 1, 2008, New York updated the statewide 2007 Energy Conservation Construction Code of New York State which is based upon the 2004 IECC for residential and IECC 2003 for commercial buildings with state specific amendments. Additionally, New York approved a state specific trade options for homes which allows for high efficiency furnaces, boilers, heat pump units efficiency, and tightly sealed homes to gain credit against insulation values upon verification. The verification will include efficiency inspections as well as qualified blower door testing and duct testing. For the first time, the efficiency measures above will give credit in consideration of condensing gas furnaces with modulating aquastats, tested duct sealing (duct blaster testing), oil furnace fan motor efficiency (EUR) in conjunction with AFUE, air changes per hour (ACH) as measured by blower door testing on individual homes, and heat pump Heating Season Performance Factors (HSPF).
