This is a normative appendix and is part of this standard

New buildings shall comply with at least one of the following sections:

  1. More efficient HVAC equipment in accordance with Section I2.
  2. Reduced lighting power density in accordance with Section I3.
  3. Enhanced digital lighting controls in accordance with Section I4.
  4. Dedicated outdoor air systems with energy recovery ventilation in accordance with Section I5.
  5. High-efficiency service water heating in accordance with Section I6.
  6. Enhanced envelope performance in accordance with Section I7.
  7. Reduced air infiltration in accordance with Section I8.

Tenant spaces shall comply with I2, I3, I4, I5 or I6. Alternatively, tenant spaces shall be in compliance with Section I7 or I8 where the entire building is in compliance.


Previously occupied tenant spaces that comply with this code using Section

Equipment shall exceed the minimum efficiency requirements listed in Tables 6.8.1-1 through 6.8.1-7, and Tables 6.8.1-9 through 6.8.1-16 by 10%, in addition to the requirements of Section 6. Where multiple performance requirements are provided, the equipment shall exceed all requirements by 10%. Equipment not listed in Tables 6.8.1-1 through 6.8.1-7, and Tables 6.8.1-9 through 6.8.1-16 shall be limited to 10% of the total building system capacity.
The total interior lighting power (watts) of the building shall be determined by using 90% of the lighting power values specified in Table 9.5.1 times the floor area for the building types, or by using 90% of the interior lighting power allowance calculated by the Space-by-Space Method in Section 9.6.

Interior lighting in the building shall have the following enhanced lighting controls that shall be located, scheduled and operated in accordance with Section

  1. Luminaires shall be configured for continuous dimming.
  2. Luminaires shall be addressed individually. Where individual addressability is not available for the luminaire class type, a controlled group of not more than four luminaires shall be allowed.
  3. Not more than eight luminaires shall be controlled together in a daylight area.
  4. Fixtures shall be controlled through a digital control system that includes the following functions:

    1. 4.1. Control reconfiguration based on digital addressability.
    2. 4.2. Load shedding.
    3. 4.3. Individual user control shall be capable of being reconfigured through the digital control system.
    4. 4.4. Occupancy sensors shall be capable of being reconfigured through the digital control system.
  5. Construction documents shall include submittal of a Sequence of Operations, including a specification outlining each of the functions in Item 4 of this section.
  6. Functional testing of lighting controls shall comply with Section 9.4.3.
Buildings containing equipment or systems regulated by Section,,,,,,,,,,,,,, or shall be equipped with an independent ventilation system designed to provide not less than the minimum 100% outdoor air to each individual occupied space, as specified by the New York City Mechanical Code. The ventilation system shall be equipped with an energy recovery system meeting the requirements of Section (Note: Option I5 may not be selected where energy recovery ventilation is prohibited by the New York City Mechanical Code or otherwise prohibited). The HVAC system shall include supply-air temperature controls that automatically reset the supply-air temperature in response to representative building loads, or to outdoor air temperatures. The controls shall reset the supply-air temperature not less than 25% of the difference between the design supply-air temperature and the design room-air temperature.

Buildings shall be of the following types to use this compliance method:

  1. Group R-1: Boarding houses, hotels or motels.
  2. Group I-2: Hospitals, psychiatric hospitals and nursing homes.
  3. Group A-2: Restaurants and banquet halls or buildings containing food preparation areas.
  4. Group F: Laundries.
  5. Group R-2.
  6. Group A-3: Health clubs and spas.

The building service water-heating system shall have one or more of the following that are sized to provide not less than 60% of the building's annual hot water requirements, or sized to provide 100% of the building's annual hot water requirements if the building shall otherwise comply with Section

  1. Waste heat recovery from service hot water, heat-recovery chillers, building equipment, or process equipment.
  2. On-site renewable energy water-heating systems.
The thermal performance of the envelope as designed shall demonstrate a minimum 15% improvement compared to the prescriptive U-,C-, and‡ F-factor requirements of Section 5.5.

Air infiltration shall be verified by whole-building pressurization testing conducted in accordance with ASTM E779 or ASTM E1827 by an independent third party. The measured air-leakage rate of the building envelope shall not exceed 0.25 cfm/ft2 under a pressure differential of 0.3 inches water column (75 Pa), with the calculated surface area being the sum of the above- and below-grade building envelope. A report that includes the tested surface area, floor area, air by volume, stories above grade, and leakage rates shall be submitted to the building owner.


For buildings having over 250,000 square feet of conditioned floor area, air leakage testing need not be conducted on the whole building where testing is conducted on representative above-grade sections of the building. Tested areas shall total not less than 25% of the conditioned floor area and shall be tested in accordance with this section.
