NYStretch Energy Code-2020

NYStretch Energy Code – 2020* Version 1.0 (NYStretch) is now available. NYStretch was developed by NYSERDA 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 ECCC-NYS) 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


NYStretch Energy Code-2020, Version 1.0: An Overlay of the 2018 International Energy Conservation Code and ASHRAE Standard 90.1-2016 [PDF]


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.

How can communities benefit from adopting and enforcing a Stretch Code like the NYStretch Energy Code-2020?

Voluntary stretch codes are permitted by law in New York State, as more restrictive local standards. Communities can benefit from adopting and enforcing a stretch energy code in many ways including, but not limited to:

  • Significant energy and utility cost savings for homeowners, tenants, renters, and building owners
  • Reduced building operational costs
  • Reduced environmental impact
  • Increased occupant comfort and health
  • Increased real estate value and community attractiveness
  • Improved resiliency from power disruptions
  • Research and development stimulation and commercialization of products that improve energy efficiency performance
  • Green job creation related to next generation technologies, code enforcement, quality control, building commissioning, energy auditing and modeling, among others

A more stringent energy code requires homes and commercial buildings to be more efficient, which reduces the amount of electricity, natural gas, and fuel oil used. While energy efficiency improvements often make sense to implement financially, these improvements may not be implemented for a variety of reasons. Adopting a stretch energy code is an effective way to implement energy efficiency and renewable energy measures, as it will be required by law for the communities that adopt it. In turn, communities that adopt a stretch energy code will reduce energy costs for current and future homeowners and renters and mitigate operating costs for small and large businesses located within the community.

NYStretch development and historical documents

NYStretch was developed with guidance from a 25-member advisory group composed of public and private stakeholders and energy experts. NYSERDA held a public comment period in 2018 seeking feedback on the draft from architects, engineers, building professionals, and local government officials. NYSERDA reviewed and, where necessary, revised the draft document based on those comments. 

Historical documents related to the development of NYStretch include:

*Note: Certain historical documents refer to the NYStretch Energy Code with “2018” or “2019” in their titles. Going forward, it will be referred to or titled “NYStretch Energy Code-2020” as it will overlaythe 2020 ECCC NYS when that energy code is released by New York State Department of State.
