General Notes — 2025 NYCECC
Provide control devices with required power pack, room controller, or other device as shown on plan per manufacturer specifications.
Zoning: provide per light type or as shown on plan; all zones shall have distinct control circuits per C405.2.1.3.
Control stations: coordinate configuration, number, height, and location with ADA requirements per ICC A117.1.
LPD: all spaces shall not exceed max LPD per 2025 NYCECC Table C405.3.2(1). LPD applies to all permanently installed lighting.
NYC LL88: Buildings >25,000 SF — tenant electrical submetering required for each tenant space >5,000 SF. Coordinate with LL88 requirements simultaneously with NYCECC compliance.
NYC LL97: Carbon intensity reporting required. Lighting LPD compliance directly impacts carbon penalty calculations. Class B office: 0.00846 tCO2e/SF by 2030.
⚡ REV 63 — C405.13 AUTO RECEPTACLE CONTROL: Effective with 2025 NYCECC enforcement (March 30, 2026), automatic plug load control is MANDATORY in all offices, conference rooms, and open work areas. At minimum, 50% of 125V, 15A & 20A receptacles in these spaces must be on controlled circuits that auto-de-energize with the occupancy sensor (15-min timeout). Controlled receptacles must be marked with △ per C405.13.1. Provide at least one always-on hot receptacle per workstation. Coordinate controlled receptacle switching with the lighting control panel or a dedicated plug load controller relay output. See note E and C405.13 code modal for full requirements.
Controls Notes — 2025 NYCECC Citations
A. DIMMING — C405.2.3 (2025 NYCECC): MANDATORY for general lighting in: classrooms/lecture halls/training rooms, conference/multipurpose/meeting rooms, dining areas (bar/lounge, leisure, family), gymnasiums/fitness centers, healthcare imaging rooms/exam rooms/nurseries/nurses' stations, laboratories, library reading rooms, lobbies, lounge/break rooms, offices (all), and spaces not provided with occupant sensor controls per C405.2.1.1. Control function (C405.2.3.1): Manual controls shall allow continuous dimming from full output to 10% of full power or lower, plus full off. Manual dimmer control required within each room. Exception: High-end trim controls exempt if calibration accessible only to authorized personnel and users cannot override above trim setpoint. Exception: Luminaires with special application controls per C405.2.5.
B. DAYLIGHT RESPONSIVE CONTROLS — C405.2.4 (2025 NYCECC): MANDATORY when installed general lighting wattage within a daylight zone exceeds the trigger threshold below. Applies to each zone independently — exceeding the threshold in one zone does not require controls in others.
Zone TypeWattage TriggerZone Depth (from glazing face)Glazing Qualification
Primary Sidelit>75 WLesser of: 1× window head height or 15 ftVert. glazing ≥24 SF, VT ≥0.20
Secondary Sidelit>150 WFrom primary zone edge to lesser of: 2× head height or 20 ftSame fenestration as primary
Toplit — Skylights>75 W0.7× ceiling height in all directions from skylight edgeSkylight area ≥24 SF per zone
Toplit — TDDs>75 W0.7× ceiling height from TDD edge≥0.1 SF aperture per device
Zone wattage count: Sum rated input wattage of all general lighting luminaires whose photometric center falls within the zone boundary. Task, decorative, and C405.2.5 special application fixtures are excluded. Luminaires straddling the boundary within 2 ft of the perimeter may be counted at 50%. Control function (C405.2.4.1): Continuous dimming from full output to ≤15% of full rated light output (not wattage) before shutoff. Complete shutoff capability required. Step dimming is not permitted. Independent zone control required: toplit zones separate from sidelit; primary separate from secondary; each cardinal façade orientation separately controlled. Calibration accessible only to authorized personnel. When occupant sensor reduces to unoccupied setpoint, daylight controls continue operating but may not increase power above unoccupied setpoint. Commissioning (C408.3.1.3): All daylight controls shall be calibrated and functionally tested by an approved agency prior to final inspection. Verification confirms field calibration, ≤15% dim floor, smooth continuous response, and zone independence. Exceptions: (EX 1) Healthcare spaces where patient care is directly provided — patient rooms, OR, ICU, exam/treatment, nurseries (corridors, lobbies, and offices NOT exempt). (EX 2) Sidelit zones on the ground floor above grade in Group A-2 and M occupancies (toplit zones on ground floor are NOT exempt). (EX 3) Enclosed offices <250 SF. Design guide: Primary zone depth = window head height (e.g., 9 ft head → 9 ft primary zone; 12 ft head → 12 ft primary, 12–20 ft secondary). Toplit zone radius = 0.7× ceiling height (e.g., 14 ft ceiling → 9.8 ft radius; 28 ft warehouse ceiling → 19.6 ft radius). Raise head heights and use high-VT glazing to maximize daylit area per zone and reduce the number of independently controlled zones.
C. AV INTEGRATION: Refer to AV integration note on drawings per C405.2.3. Coordinate scene presets with AV contractor. Scene presets must include ≤20% level for AV/presentation mode.
D. MOTORIZED SHADES: Provide fully integrated shade connection with lighting controls system. Coordinate shade position with daylight sensor per C405.2.4. Shade position shall be communicated to the daylight responsive control system so that the photosensor setpoint can be adjusted based on shade deployment state. When shades are fully closed, the daylight control system shall operate from a stored setpoint for overcast/no-daylight conditions. Coordinate shade schedule with WELL Building Standard v2 L04 (Daylight) where applicable.
E. AUTOMATIC RECEPTACLE CONTROL — C405.13 (2025 NYCECC): REV 63 — C405.13 MANDATORY. Automatic receptacle control is required for ≥50% of all 125V, 15A and 20A receptacles in the following space types: enclosed offices, conference rooms, copy/print rooms, breakrooms, classrooms, open plan office areas, and individual workstations (including modular partitions/workstation systems). Additionally, ≥25% of branch circuit feeders installed for modular furniture not shown on construction documents must be controlled.

Control method — one of the following (C405.13.1): (2.1) Timeclock — scheduled time-of-day control, programmable per day, zone ≤5,000 SF and ≤1 floor, 2-hour manual override permitted, override switch controls ≤5,000 SF; (2.2) Occupant sensor — turns off receptacles within 15 minutes of all occupants leaving; (2.3) Automated signal from another control/alarm system — off within 15 minutes of determining unoccupied.

Receptacle configuration (C405.13.1 item 1): Either provide split controlled receptacles with the top receptacle controlled, or provide a controlled receptacle within 12 inches of each uncontrolled receptacle.

Marking (C405.13.1 item 3): All controlled receptacles shall be permanently marked per the NYC Electrical Code and be uniformly distributed throughout the space. Plug-in devices do not comply (C405.13.1 item 4).

Exceptions: (1) Receptacles for continuous operation equipment (24/7/365); (2) Spaces where auto control would endanger safety/security; (3) Within a single modular workstation, uncontrolled receptacles may be >12 in. but ≤72 in. from controlled receptacles.
F. PARTITION SENSOR: Rooms act independently when partition in place; zones unify when partition removed. Each partition zone separately zoned per C405.2.1.3.
G. TUNABLE WHITE: Tunable white controls with circadian programming per IES TM-18. CCT range 2700K–6500K. Coordinate with WELL Building Standard v2 L07.
H. DEMAND RESPONSIVE LIGHTING CONTROLS — C405.2.8 (2025 NYCECC): MANDATORY for interior general lighting in Group B (Business), E (Educational), M (Mercantile), and S (Storage) occupancies — covering not less than 75% of interior floor area. Upon receipt of a utility/grid demand response (DR) signal: (1) Reduce lighting output to ≤80% of full power (or ≤80% of high-end trim setpoint if trim is set); (2) Dim gradually and continuously over not more than 15 minutes to achieve the DR setpoint; (3) Automatically restore to normal settings after the DR event ends. Exceptions (C405.2.8): Buildings <10,000 SF total Group B/E/M/S area; buildings where DR signal is not available from a controlling entity other than the owner; parking garages; ambulatory care facilities; outpatient clinics; physician or dental offices. Warehouse/storage areas exception: may switch off ≥25% of general lighting power rather than dimming. Coordination required with utility/grid aggregator for DR signal protocol (typically OpenADR 2.0 or BACnet). Commissioning per C408.3.1.6 required for buildings claiming C406.3.2 credits.
I. COMMISSIONING — C408.3 FUNCTIONAL TESTING (2025 NYCECC): MANDATORY per C405.1: Lighting controls shall be commissioned per C408.3 prior to passing final inspection. An approved agency shall provide evidence that all lighting and receptacle control systems have been tested to ensure control hardware and software are calibrated, adjusted, programmed, and in proper working condition. Testing protocols: Occupant sensors (C408.3.1.1): ≤7 sensors → test all; >7 → test ≥10% of each unique type/geometry; ≥30% fail → test all; verify auto-off timing, on-level, manual-on behavior, and no cross-zone false triggering. Time-switch controls (C408.3.1.2): Confirm programming (weekday/weekend/holiday), correct time/date, battery backup, and ≤2-hr override limit; simulate occupied and unoccupied conditions. Daylight controls (C408.3.1.3): Verify field calibration, setpoints, and response to available daylight. High-end trim (C408.3.1.4): Verify trim set, calibration secured, users cannot override above trim max. Documentation due within 90 days of CO (C408.3.2): Equipment location drawings, O&M manuals (setpoints, service contacts, maintenance schedules, recalibration schedule), and test results report with deficiency disposition.

▸ Every watt over LPD limit = CO₂ overage = LL97 fine. It's literally arithmetic.
▸ No compliant controls = DOB violations AND LL97 carbon penalties. Two bills. One bad spec.
▸ Smart, dimmable, sub-metered controls are now a financial instrument — not a compliance checkbox.

ASHRAE 90.1-2022 drives it. Private office toward 0.78 W/SF. No space type escapes.
● HIGH CONFIDENCE

● MED CONFIDENCE
Wireless / Addressable Systems
600 SF zone limits only achievable with wirelessly-commissioning addressable fixtures.
● MED CONFIDENCE
Performance-Based Path (LL32)
Local Law 32 mandates a performance compliance path by 2028 — measured vs. predicted energy.
● LOW CONFIDENCE
Fixture-Integrated Sensors Required
Possible rule: sensors must be part of the luminaire assembly in spaces >1,000 SF.
● LOW CONFIDENCE
LL97 + NYCECC Formally Linked
Exceeding LPD may directly trigger LL97 carbon fine exposure — penalty frameworks merge.

For Reference and Education Only
This document is prepared for educational and reference purposes only. It does not constitute legal, engineering, or code compliance advice. Always consult the full 2025 NYCECC text and your project's Authority Having Jurisdiction (AHJ).
Always Verify with the AHJ
Code interpretations vary by jurisdiction, project type, and occupancy. The NYC Department of Buildings and the project AHJ have final authority on all code compliance determinations.
A Licensed Engineer Must Review All Designs
Lighting and controls designs must be reviewed and stamped by a licensed Professional Engineer (PE) or Registered Architect (RA) before submission to the NYC Department of Buildings.
Emergency Lighting Is Exempt from Energy Controls
Emergency lighting circuits governed by NEC Article 700 are fully exempt from 2025 NYCECC energy control requirements per C405.2 Exception 3. Never apply occupancy sensors or dimmers to emergency circuits.
LPD Values Are Maximum Limits — Not Design Targets
Maximum Lighting Power Density (LPD) values are code-mandated upper limits. Good lighting design should target significantly lower installed power while meeting IES illuminance recommendations.
2025 NYCECC Enforcement Date: March 30, 2026
The 2025 NYCECC is mandatory for all permit applications filed on or after March 30, 2026. Projects permitted before this date may use prior code. Verify permit date with the NYC DOB.
IES Footcandle Targets Are Recommendations
IES illuminance targets shown are from IES RP-1 and related standards and are design recommendations, not code requirements. Final illuminance levels must suit the specific tasks, occupants, and conditions of each space.
