MODIFIED ENERGY STANDARD FOR BUILDINGS, EXCEPT FOR LOW-RISE RESIDENTIAL BUILDINGS
This appendix provides the modifications to the nationally recognized standard ASHRAE 90.1-2010, governing commercial energy efficiency. Where a referenced publication has been modified for the City of New York as by the New York City Construction Codes and the New York City Energy Conservation Code, every reference to such publication shall be deemed to include all such modifications.
The standards for energy efficiency in commercial buildings, as defined in Section C202 of this code, shall be in accordance with Chapter C4 of this code or in accordance with ASHRAE 90.1-2010 as amended by chapter 3 of the 2014 Supplement and Section 28-1001.2.3 of the Administrative Code. Refer to the rules of the department for any subsequent additions, modifications or deletions that may have been made to this standard in accordance with Section 28-103.19 of the Administrative Code.
The following New York City amendments to ASHRAE 90.1-2010, as amended by Chapter 3 of the 2014 Supplement, are hereby adopted as set forth in this section.

Chapter 2 ‒ Definitions, Abbreviations, and Acronyms

2.2 Delete Section 2.2 and replace with the following:

2.2 The provisions of this standard do not apply to:

(a) detached one-family dwellings having not more than three stories above grade plane;

(b) detached two-family dwellings having not more than three stories above grade plane;

(c) buildings that (i) consist of three or more attached townhouse units and (ii) have not more than three stories above grade plane;

(d) buildings that (i) are classified in accordance with Chapter 3 of the 2010 edition of the Building Code of New York State in Group R-2, R-3 or R-4 and (ii) have not more than three stories above grade plane;

(e) factory manufactured homes (as defined in section 372(8) of the Executive Law); and

(f) mobile homes (as defined in section 372(13) of the Executive Law).

For the purposes of this section 2.2, the term "grade plane" means a reference plane representing the average of finished ground level adjoining the building at exterior walls. Where the finished ground level slopes away from the exterior walls, the reference plane shall be established by the lowest points within the area between the building and the lot line or, where the lot line is more than 6 feet (1829 mm) from the building, between the building and a point 6 feet (1829 mm) from the building, and the term "townhouse unit" means a single-family dwelling unit constructed in a group of three or more attached units in which each unit (i) extends from the foundation to roof and (ii) has open space on at least two sides.

The provisions of this standard do apply to all buildings not included in (a), (b), (c), (d), (e) of (f) of this Section 2.2. In particular, but not by way of limitation, the provisions of this standard do apply to detached one-family dwellings having more than three stories above grade plane.

Chapter 6 ‒ Heating, Ventilation, and Air-Conditioning

6.7.2.4 Delete Section 6.7.2.4 in its entirety and replace with a new Section 6.7.2.4 to read as follows:

6.7.2.4. Projects complying with this standard shall also comply with Section C408 of the New York City Energy Conservation Code in regards to system commissioning. When demonstrating compliance with Section C408.3.1, projects following ASHRAE 90.1-2010 must demonstrate compliance with Chapter 9 of ASHRAE 90.1-2010 as required, in lieu of Section C405 of the New York City Energy Conservation Code.

b. Nonstandard size units must be factory labeled as follows: "MANUFACTURED FOR NONSTANDARD SIZE APPLICATIONS ONLY: NOT TO BE INSTALLED IN NEW STANDARD PROJECTS." Nonstandard size efficiencies apply only to units being installed in existing sleeves having an external wall opening of less than 16 in. high or less than 42 in. wide and having a cross-sectional area less than 670 in2.
c. Cap means the rated cooling capacity of the product in Btu/h. If the unit's capacity is less than 7000 Btu/h in the calculation. If the unit's capacity is greater than 15,000 Btu/h, use 15,000 Btu/h in the calculation.

b. Combination units not covered by the NAECA (3-phase power or cooling capacity greater than or equal to 19 kW) may comply with either rating.
c. Compliance of multiple firing rate units shall be at the maximum firing rate.
d. Et= thermal efficiency. Units must also include an interrupted or intermittent ignition device (IID), have jacket losses not exceeding 0.75% of the input rating, and have either power venting or a flue damper. A vent damper is an acceptable alternative to a flue damper for those furnaces where combustion air is drawn from the conditioned space.
e. Ec = Combustion efficiency (100% less flue losses). See test procedure for detailed discussion.
f. As of August 8, 2008, according to the Energy Policy Act of 2005, units must also include an interrupted or intermittent ignition device (IID) and have either power venting or an automatic flue damper.

c. the energy efficiency level of components specified in the building design meet or exceed the efficiency levels used to calculate the design energy cost.

The entry in the "Budget Building Design" column of Section 6 of Table 11.3.1 ASHRAE 90.1-2010 shall be deemed to be amended to read as follows:

Lighting power in the Budget building design shall be determined using the same categorization procedure (building area or space-by-space method) and categories as the proposed design with lighting power set equal to the maximum allowed for the corresponding method and category in either Section 9.5 or 9.6. Power for the fixtures not included in the LPD calculation shall be modeled identically in the proposed building design and budget building design. Lighting controls shall be the minimum required.

Automatic Daylighting Controls for Primary Sidelighted Areas shall be modeled with the following parameters:

• Light Output and Power Fractions shall be as follows based on type of dimming control modeled:

o Stepped Dimming: Light output and power shall decrease in equivalent steps of 100 percent, 66 percent, and 33 percent; or

o Continuous Dimming: Light output and power shall both decrease continuously to 33 percent of peak output and power.

• The daylight control reference point(s) shall be located at the center of the width and at the depth of the primary sidelighted area. If the primary sidelighted area includes apertures with orientations that differ by more than 45 degrees, then the model shall include one daylight control reference point for each orientation. (Note: if the modeling tool is limited by the number of daylight control reference points allowed per zone then the number of zones modeled may need to be increased.)
