2020 New York City Energy Conservation Code

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.

Below are the key changes to expect*:

  • Building envelope improvements, including the requirement that all heated slabs be insulated
  • More stringent fenestration requirements
  • Reorganization of HVAC provisions
  • Increased HVAC efficiency requirements for small furnaces, large steam boilers, and cooling towers
  • Improvements in economizer requirements, including economizer fault detection and diagnostics
  • Addition of hotel guestroom occupancy controls on temperature, ventilation, and lighting
  • 90% high-efficacy light fixtures are now required in all dwelling units
  • Reduced lighting power densities
  • Reduced wattage exception for daylighting controls
  • Added requirement for regenerative drive elevators
  • Added requirements for commercial kitchen equipment electrical efficiencies
  • Whole-building fuel-metering requirements, for buildings 25,000 s.f. and above)
