NYStretch Energy Code — 2020 An Overlay of the 2018 International Energy Conservation Code and ASHRAE Standard 90.1-2016 Version 1.0 | July 2019 NYStretch Energy Code 2020 ii PREFACE The NYStretch Energy Code 2020 project was undertaken by NYSERDA to develop a pivotal tool for New York jurisdictions to support the State’s energy and climate goals by accelerating the savings obtained through their local building energy codes. Authorities having jurisdiction have the legal ability to voluntarily adopt NYStretch-Energy. The NYStretch Code was developed as a statewide model code to save more energy than New York’s minimum code and to be readily adopted as a more stringent local standard to the ECCCNYS. It was developed with the following goals:  Technically sound  Thoroughly reviewed by stakeholders  Written in code enforceable language  Fully consistent with the 2018 IECC, ASHRAE 90.1-2016, and uniform codes For communities that adopt it, the NYStretch Code will provide greater savings over the ECCCNYS for both residential and commercial buildings. Marginal Markings Solid vertical lines in the margins of Parts 1, 2, and 3 indicate a technical change from the requirements of 2018 IECC and ASHRAE 90.1-2016. Black, right-facing arrows in the left-hand margin indicate a deletion from the requirements. Unaffected Provisions The chapters, sections, tables, and other provisions in the 2018 IECC and ASHRAE 90.1-2016 not amended by NYStretch Code shall continue in full force and effect. Nothing in the NYStretch Code shall be construed as deleting all or part of any unaffected provision. Severability If any portion of the NYStretch Energy Code 2020, the 2018 IECC or ASHRAE 90.1-2016 is held by a court of a competent jurisdiction to be illegal or void, such holding shall not affect the validity of any other portion of the NYStretch Code, the 2018 IECC or ASHRAE 90.1-2016 Implied license / Use of NYStretch While a jurisdiction may adopt one or both of the Commercial and Residential provisions, it is NYSERDA’s desire, but not a rule, that the NYStretch be adopted as written. Changes to or deletions of the provisions contained herein may affect energy savings, cost savings, and enforceability. Jurisdictions are encouraged to contact NYSERDA codes@nyserda.ny.gov before considering any changes to the NYStretch. NYStretch Energy Code 2020 iii DISCLAIMER Version 1 of NYStretch Energy Code-2020 (NYStretch) 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 New York State Energy Conservation Construction Code (2020 NYS ECCC). Visit https://www.dos.ny.gov/DCEA/CodeUpdate.html for updates on the 2020 NYS ECCC. Furthermore this version of NYStretch does not contain changes to it that New York City may adopt for the 2020 Energy Conservation Code of New York City (2020 ECC NYC). Visit https://www1.nyc.gov/site/buildings/codes/energy-conservation-code.page for updates on the 2020 ECC NYC. It is NYSERDA’s intent to release a version of NYStretch that will overlay the 2020 NYS ECCC upon release of that code by New York State Department of State. Stringency of NYStretch NYSERDA recognizes that there are differentials between the requirements of the IECC and ASHRAE paths in NYStretch. It is NYSERDA’s intent to create two separate inclusive code books, one for the IECC paths and another for the ASHRAE paths and find and correct the differentials between those code provisions such that they are consistent with the intent and stringency of NYStretch. Until that time, where there is a differential between the paths, the more stringent of the requirements will prevail. Rights under NYSERDA’s license agreement with International Code Council, Inc.
