As of October 2016, New York operates under the 2015 IECC and ASHRAE 90.1 2013 energy codes and is looking to update to the 2018 IECC and 90.1 2016 ASHRAE codes by first quarter 2020. New York City's Energy code is more efficient than the state code and is updated on a bi-annual basis to ensure it is a leading force in energy codes in the region. Thanks to New York's regular review process, their codes are updated often as it continues its commitment to advancing energy efficiency, especially with regard to their state stretch code.
STRETCH CODE: NYSERDA has released its NYStretch Energy Code 2020, which is 25% more efficient than the 2018 IECC. This aims to provide a straightforward, flexible approach to achieving this efficiency boost in energy savings beyond code for residential, commercial, and multi-family buildings. NYSERDA works to update this regularly as NYC is committed to being a leader in building technologies and efficiency to improve energy use and affordable housing options.
NEW: Currently introduced and on the floor is Assembly Bill 5708, which would require New York to consider and modify all new IECC codes within 18 months of their publication so that they can be applied seamlessly to New York residential buildings while meeting or exceeding current energy code requirements for energy efficiency. It would also require all new residential homes to undergo a Home Energy Rating System (HERS) rating as defined by the RESNET definition by a certified rater and necessitate various (20-30%) reductions in modeled energy consumption compared to a reference building of comparable parameters.
