NYStretch Energy Code-2020

NYStretch Energy Code – 2020* Version 1.0 (NYStretch) is now available. NYSERDA developed NYStretch as a statewide model code for New York jurisdictions to use to meet their energy and climate goals by accelerating the savings obtained through their local building energy codes. For jurisdictions that adopt it, NYStretch will provide savings of roughly 11% over the 2020 Energy Conservation Construction Code of New York State (2020 ECCCNYS) when that energy code is released by New York State Department of State.

NYStretch is a stretch code that:

  • Is readily adoptable with minimal changes by local governments
  • Is in enforceable language
  • Is coordinated with the New York State Uniform and Energy Codes
  • Is about one cycle ahead of the next New York State Energy Code in its requirements
  • Lowers energy use and greenhouse gas emissions associated with new and existing buildings
  • Is cost-effective and regionally appropriate

It is NYSERDA’s intent to release a version of NYStretch that will overlay the 2020 ECCCNYS upon release of that code by New York State Department of State.  NYStretch Version 1.0 is an overlay of the 2018 International Energy Conservation Code (2018 IECC) and ASHRAE Standard 90.1-2016 (ASHRAE). It does not reflect changes the New York State Fire Prevention and Code Council may adopt for the 2020 ECCC NYS.
