Statement of Basis and Purpose of Proposed Rule

 

The Department of Buildings (DOB) is proposing to add a new rule to make corrections to the reference standard ASHRAE 90.1, as identified in Appendix CA of the Energy Conservation Code, and to clarify modeling methodology for lighting and pump controls.

 

Specifically, the proposed rule:

  • Adds a new section 5000-02 regarding lighting control requirements under American Society of Heating, Refrigerating and Air Conditioning Engineers (“ASHRAE”) 90.1 to Title 1 of the RCNY,
  • Adds clarifying language to Section 9.4.1.1, item c, which was omitted due to typographical error.  The requirement for occupancy controls for open plan offices was added by the City, but the requirement for partial automatic ON was intended to be exempted,
  • Updates the requirements of Table 9.6.1 to conform it to the requirements of ASHRAE standard 90.1-2013.  These control requirements were omitted from Local Law 91 of 2016 due to typographical error,
  • Further clarifies certain modeling requirements based on published addenda to ASHRAE 90.1-2013, 
  • Revises Section 4.2 to clarify that Appendix G is allowed for additions and alterations, and Section 11 is allowed for alterations,
  • Revises Table G3.1, number 6, Lighting, to correct an inconsistency in modeling the lighting baseline requirements for not yet designed spaces and add details on modeling lighting controls,
  • Revises Table G3.1.1-4 to modify a footnote to be consistent with the modeling approach of setting the baseline heat fuel source by climate zone,
  • Revises Sections G3.1.3.5, G3.1.3.10 and G3.1.3.11 to provide more detail for the baseline model with regard to pumps, and
  • Revises Table G3.7 to clarify the allowable reduction in lighting LPD when applying occupancy controls to the baseline lighting.

 The Department of Buildings’ authority for this proposed rule is found in sections 643 and 1043 of the New York City Charter, section 28-103.19 of the New York City Administrative Code and section ECC CA102.1 of the New York City Energy Conservation Code.
