Energy Codes: Training, Support Services and Stretch Codes

Energy codes set minimum energy efficiency requirements for designing, constructing and renovating buildings. When enforced, energy codes promise long-term energy and cost savings over the lifetime of a building.

The 2020 Energy Conservation Construction Code of New York State (”2020 State Energy Code”) is administered by the Department of State, Division of Building Standards and CodesLink opens in new window - close new window to return to this page..

NYSERDA works with building design, construction and enforcement professionals, state and local governments, and industry advocacy groups to inform strategies for improving compliance and enforcement, and test approaches to advance high-performance code development and adoption. This includes:

  • Energy Code Training and Support Services: NYSERDA offers free and low-cost training and support services to code enforcement officials, architects, engineers, building energy professionals, and members of the construction trades—all designed to improve compliance with the State Energy Code.
  • NY-Stretch Energy Code–2020: NYSERDA’s latest voluntary, locally-adoptable stretch energy code, NY-Stretch Energy Code–2020 is roughly 20% more efficient than the residential provisions of the 2018 International Energy Conservation Code (IECC) and roughly 7% more efficient than the commercial provisions of ASHRAE 90.1-2016 for an overall increased efficiency of 11% over the 2020 NYS Energy Code.
