NYStretch Energy Code-2020

NYStretch Energy Code – 2020* is NYSERDA’s latest voluntary, locally adoptable stretch energy code, drafted with guidance from a 25-member advisory group composed of public and private stakeholders. NYStretch Energy Code – 2020 is roughly 25% more efficient than the residential provisions of the International Energy Conservation Code (IECC)–2018 and roughly 5% more efficient than the commercial provisions of ASHRAE 90.1-2016.

*Note: The naming of the stretch energy code has been modified. Certain historical documents still contain in their title its previous name as “NYStretch Energy Code-2018.” Going forward, it will be referred to or titled “NYStretch Energy Code-2020” as it will overlay the 2020 Energy Conservation and Construction Code of New York State when that energy code is released by New York State Department of State.

Current Status

A four-week public comment period on the draft NYStretch Energy Code-2020 closed April 3, 2018. NYSERDA sought feedback on the draft from architects, engineers, building professionals, and local government officials. View a summary of the public comments [PDF]. NYSERDA reviewed and, where necessary, revised the draft document and released the final draft version of NYStretch Energy Code-2019 on August 16, 2018. Once finalized, the code will be available on this page and on the International Code Council website for download.

More Information on NYStretch Energy Code-2020

The goals for this effort were to provide 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

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.
