NYC Green Schools Guide

The NYC Green Schools Guide and Rating System was developed to guide the sustainable design, construction and operation of new schools, modernization projects and school renovations, and to achieve compliance with Local Law 86 of 2005 (New York City's Green Building Law). Local Law 86/2005 established a set of demanding sustainable standards for public design and construction projects in general, and makes NYC one of the first and largest school districts in the nation to have sustainable guidelines required by law. 

On March 13, 2007, the Director of the Office of Environmental Coordination, on the behalf of the Mayor, determined that the NYC Green Schools Rating System is no less stringent than LEED for New Construction, version 2.2, for the achievement of a LEED Certified rating (the minimum required by Local Law 86/2005 for school projects). Copies of the independent review of the 2007 GSG, undertaken by OEC on behalf of the Mayor, and the Mayoral Findings can be downloaded from the Mayor's Office of Sustainability website at  nyc.gov/oec.

Designing and building sustainable schools by following the NYC Green Schools Guide will utilize standards best suited to school buildings in New York City, and will allow "building green" to be integrated with the SCA's other core mandates of designing and building high quality projects within aggressive timeframes and as cost effectively as possible.

The NYC Green Schools Guide 2007 was valid for applicable projects whose design started after January 1, 2007, but before June 26, 2009.It was last revised on May 1, 2009.  For projects that started design on or after that date, applicable projects were required to follow the "NYC Green Schools Guide 2009". An update to the 2009 guide, the "NYC Green Schools Guide 2016", applies to projects that started design after May 31, 2016.  For convenience, changes from the 2009 guide are highlighted in yellow within the 2016 guide; click on the links below to view each of the guides. (Please note that for optimal viewing in hardcopy, as well as to conserve paper, the Green Schools Guide is designed to be printed double-sided).

If any errors are found in the Green Schools Guide or Forms please email the CADD Unit. The forms are regularly updated and should be taken from the website at the beginning of each phase of the project.

NYC Green Schools Rating System Forms

The following Green Schools Ratings System forms are an editable format of those provided in the 2007/2009/2016 Green Schools guides and are for the designers use in making submittals to the Authority.  These forms may differ slightly from those provided in the guides as they are updated when needed to correct errors that are found.  The 2007 forms are provided for reference and are to be used as needed to complete projects whose design started after January 1, 2007, but before June 26, 2009.  For projects that started design on or after June 26, 2009, use the 2009 Rating forms.  However, for any new submission (not resubmission) made after May 31, 2016, the 2016 forms are to be utilized.

To view the Green Schools Rating System Forms, you will need Microsoft Word and/or Microsoft Excel installed.

NYC Green Schools Rating System Sample Submissions & Frequently Used Comments

The following are examples for each design submission phase of a submission that is fairly complete and uses the appropriate Green Schools Guide forms.

Also provided for the 2009 Rating System are examples of frequently used comments for each design submission phase of a submission.

The contents of all the samples may or may not have been accepted by the GSG Committee reviewing the submission, but is intended to provide guidance as to a format that will expedite the review process and reduce the need for resubmission. Each phase submission is to be resubmitted separately until it is deemed complete. Click on the link for the appropriate sample submission for the appropriate Rating System.

Energy Modeling Use Guide and Template

The SCA has developed templates for use in project specific energy modeling based on its prototypical design case and different size buildings.  The set of templates based on ASHRAE 90.1-2013 is intended to meet the required 20% energy savings over ASHRAE 90.1-2013 as required by LL 86 of 2005. There is also set of templates based on ASHRAE 90.1-2010 for Green Schools Guide Compliance.  For projects that require energy modeling but are based on earlier versions of ASHRAE 90.1, the templates can be revised to incorporate the provisions of the earlier ASHRAE 90.1 versions.

The intent of providing these templates is to give Designers a guide to creating their own project specific models so that the models are repeatable and use consistent information.  A major item that is often guess work by the designers is the occupancy schedule.  The templates provide this information which can thus be used.  Using a uniform format and providing the information in the same manner as these templates  will allow the Green Schools Guide Review Committee to more easily review the energy models presented with the green submissions.  Designers are to provide their own modeling reports in a similar manner.  When using the template, if the designer notices a parameter at odds with the SCA design requirements, please notify the GSG committee through NYCGSG-Submissions@nycsca.org    

The eQuest Energy Modeling Guide explains how to format the modeling report and is used in conjunction with the eQuest Input Summary report, which provides the schedules and other data to be used in the model.  As indicated, the data is applicable to the SCA's prototypical model and the designer will need to input project specific parameters if something other than the prototype values are used.  Energy modelers will need to update the building geometry to reflect the actual design, and will need to verify all baseline fan power and efficiency calculations based on allowances and equipment sizes.  Each of the zip folders contain the .inp, .pd2, and .pdl file for each size school.  The main difference between the "Large_School" and "Medium_School" files are the schedules, for which High Schools have extended hours.  Again, these templates are a starting point to improve consistency among models.

Of note is that ASHRAE 90.1-2013 baselines no longer use existing envelopes, and thus an existing building template is not provided.  For addition projects, the templates do have the option to use a packaged DX unit in the corridors to serve the space between a new building and existing if necessary. 

 In order to provide a consistent format for relaying information from the energy model for review by the Green Schools Guide Committee, a sample for the report is provided.  The modeler is to ensure at a minimum information provided in the tables is included in their own report.

Green Schools Guide Construction Toolkits

In order to assist the construction team, consisting of the Contractor, Project Officer and Architect, to successfully track and document the construction phase credits for the GSG Rating System, the SCA has developed the following Toolkits.

    These Toolkits highlight the sustainability requirements included in the Contract Documents and what credits they are applied to. They should not be considered all inclusive; they are based on the current SCA Standard Specifications and thus the Contract Documents may have different or additional requirements that are to be incorporated in the same manner.
