Energy Conservation Code


The New York City Energy Conservation Code (NYCECC) is comprised of New York City local laws and the current Energy Conservation Construction Code of New York State (ECCCNYS). By State law, all local government energy codes, including the NYCECC, must be more stringent than the ECCCNYS.

2016 NYC Energy Conservation Code

2014 NYC Energy Conservation Code

2011 NYC Energy Conservation Code


UPDATE: 2016 New York City Energy Conservation Code

The 2016 New York State Energy Conservation Construction Code, based on the 2015 International Energy Conservation Code and ASHRAE 90.1-2013 – as modified by the State of New York, will go into effect on October 3, 2016. Adopted as Local Law 91 of 2016, the 2016 New York City Energy Conservation Code (NYCECC), based on the State Code and further modified, will also go into effect on October 3, 2016. Legislation is currently pending with New York City Council to amend the 2016 NYCECC based on recent changes made by the NYS Supplement. Please visit our website periodically for updates.


Application Submittal

  • Applications filed on or after October 3, 2016 will be subject to the 2016 NYCECC. Complete applications filed on or before October 2, 2016 will be subject to the 2014 NYCECC.

    NOTE: Complete applications are those that meet the submittal requirements of Buildings Bulletin 2014-015 and include a complete energy analysis.
  • Incomplete applications filed on or before October 2, 2016, may be subject to the 2016 NYCECC.

Local Law 91 of 2016 may be found on the New York City Council’s website.  Once available, a published hard copy version can be purchased at the City Store will be available for purchase, and will also be viewable on this webpage.


Applicability

The 2016 NYCECC applies to completed job applications filed on or after October 3, 2016. All completed job applications filed on or before October 2, 2016 can continue review under the 2016 NYCECC.

 

Application Types Not Regulated by the Energy Code

Full demolition, sign and subdivision applications are not required to comply with the NYCECC. However, sign applications that affect a building’s envelope must be accompanied by an alteration application for the envelope work, which must comply with the NYCECC.

 

Variances

Under Article 11 of the New York State Energy Law, only the Secretary of State has the authority to provide waivers from Energy Code compliance, not the local jurisdiction. Contact the Codes Division of the Department of State for an application for variance at (518) 474-4073 or by email at codes@dos.state.ny.us.

 

Software for Energy Analysis

REScheck, COMcheck, and DOE2-based software can be used to conduct the energy analysis and are available for free at the US Department of Energy  and may be used as follows:

  • REScheck: The full report shall be provided, including the building envelope, HVAC/service water heating and checklists. The New York City version must be used. The IECC version of REScheck is not acceptable
  • COMcheck: Depending on whether you use NYCECC or ASHRAE Standard 90.1/2013 for compliance, the respective version of COMcheck should be used. Use the 2016 NYCECC version for ECC compliance and the ASHRAE 90.1/2013 version for compliance with that standard.
  • DOE2: For more complex energy modeling, including where trade-offs among disciplines or renewable energy sources are used, a DOE2-based software should be used. Such software, including updates, may include DOE2.1E, VisualDOE, EnergyPlus or eQuest. Other energy modeling programs must be approved by the Secretary of State of New York and the Buildings Commissioner prior to submission.

     

Required Documents for Construction Sign-Off

The following documents must be completed and submitted to the Department in order to ensure all work is in compliance with the New York City Energy Conservation Code (NYCECC) and before the Department can sign-off on al completed work:

TR8: Technical Report Statement of Responsibility for Energy Code Progress Inspections: The progress inspector must certify that all Progress Inspections noted on the original TR8 and on TR8s filed with in any post-approval amendments (PAAs) have been satisfied. The progress inspector must sign and seal the TR8, certifying that inspected work complies with the approved drawings

EN2: Certification of Conformance with As-Built Energy Analysis: The progress inspector(s) must certify on this form that the as-built values for energy in the building match the values in the last-approved Energy Analysis. If they do not, then an as-built energy analysis must be prepared by the applicant of record and the progress inspector(s) must certify on the EN2 Form  that the as-built values for energy in the building match the values in the as-built energy analysis. The as-built energy analysis must be professionally certified and submitted with the EN2 form at sign-off.

 

When Construction has Changed from the Approved Drawings

Design applicants are required to update their drawings, including the energy analysis, when conditions result in a design change during construction (Section ECC 103.4). These drawings, including the energy analysis, must be submitted to the Department for approval.

If construction differs from the last-approved energy analysis prior to sign-off, the original preparer of the energy analysis must prepare an as-built energy analysis using the values actually used in the construction. The energy analysis must demonstrate compliance with the NYCECC and the preparer must sign and seal the analysis, certifying that the work is in compliance. The progress inspector must then certify in the EN2 form that the values in the professionally certified energy analysis match the existing construction.

If the construction changes result in a building no longer complying with the NYCECC, as demonstrated by a failed energy analysis, the progress inspector cannot certify on the EN2 Form that the work is in compliance and the application cannot be signed-off.
