The 2020 NYCECC, which is based on the 2018 International Energy Conservation Code, ASHRAE Standard 90.1-2016, and NYSERDA’s NYStretch Energy Code-2020, will go into effect on May 12,2020.
All applications completed on or after May 12, 2020, will be subject to the 2020 NYCECC. “Complete applications” (as defined by Buildings Bulletin 2020-002) filed before May 12, 2020, will be subject to the 2016 NYCECC. If these applications are deemed “incomplete”, they may be subject to the 2020 NYCECC.
As of April 20th, 2020 the 2020 NYCECC has been released, and a digital copy is available for viewing on the DOB’s Energy Conservation Code page.
