New York State and New York City are both expected to update their energy codes by the end of 2016 at the latest. While these codes have not been published yet, it is possible to understand at least 95% of their content by carefully following the code development process.

This presentation provides an update of lighting-related requirements expected to be found in the new energy codes, as well as highlighting important aspects of the current code which are commonly overlooked.

• Status of 2016 energy code adoption process in New York State and the City of New York.

• Applicability of residential and commercial energy codes.

• Lighting requirements applicable to residential occupancies.

• What’s new for lighting in the 2015 IECC and Standard 90.1 - 2013.

• Advantages and disadvantages of applying Chapter C4 of the IECC compared to Standard 90.1 for commercial projects.

• In-depth understanding of the new daylight responsive control requirements in the commercial energy code.

The City of New York maintains its’ own energy conservation code. This is a local law passed by city council, and is an overlay of the state code. The city is permitted to do this, so long as the city’s code is more stringent than the state’s.

Nov 9, 2015 – Proposed new rule posted.Mar 9, 2016 – New York State Fire Prevention and Building Code Council expected to vote.Mar 28, 2016 to Jan 1, 2017 – Range of possible effective dates depending on Code Council vote.

• 2015 state supplement was published Nov 9, 2015 and is unlikely to undergo meaningful revision.

• IECC 2015 is complete and published.

• Standard 90.1 – 2013 is complete and published.

• City Council will likely act at some point once the state code is finalized.

NYS SUPPLEMENT

(PUBLIC REVIEW)

IECC 2015 STANDARD 90.1 - 2013

Hotels and motels are always considered commercial buildings, regardless of their height.

All other residential occupancies (apartment houses, detached houses, townhouses, dormitories, etc.) are considered commercial if they are more than three stories above grade.

2014 NYC Code:

GRADE PLANE. For the purposes of this code, 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 from the building, between the building and a point 6 feet from the building.

HISTORIC BUILDING. Any building that is(a) listed on the national register of historic places

or on the state register of historic places,(b) determined by the commissioner of parks,

recreation and historic preservation to be eligible for listing on the state register of historic places,

(c) determined by the commissioner of parks, recreation and historic preservation to be a contributing building to an historic district that is listed or eligible for listing on the state or national registers of historic places, or

(d) otherwise defined as an historic building in regulations adopted by the state fire prevention and building code council

Landmark status does not and will not confer any exceptions from energy code compliance.

ALTERATION. Any construction or renovation to an existing structure other than repair or addition that requires a permit.

No changes to alterations language.

C101.6.2. The Energy Code shall not apply to any of the following, provided that the energy use of the building is not increased:

(7) alterations that replace less than fifty percent of the luminaires in a space, provided that such alterations do not increase the installed interior lighting power; or

(8) alterations that replace only the bulb and ballast within the existing luminaires in a space provided that the alteration does not increase the installed interior lighting power.

R404.1 Lighting equipment (Mandatory). Not less than 75 percent of the lamps in permanently installed lighting fixtures shall be high-efficacy lamps or not less than 75 percent of the permanently installed lighting fixtures shall contain only high-efficacy lamps.Exception: Low-voltage lighting.

LOW-VOLTAGE LIGHTING. Lighting equipment powered through a transformer such as a cable conductor, a rail conductor and track lighting.

C405.1 General (Mandatory).

Exception: Dwelling units within commercial buildings shall not be required to comply with Sections C405.2 through C405.5, provided that they comply with Section R404.1.

2014 NYC CodeAdded these requirements to Standard 90.1 so that dwelling units are included within the scope of 90.1.

Dwelling UnitSleeping Unit

Dwelling Units

No realistic option to include in LPD calculations. Must provide 75% High Efficacy lighting.

Sleeping Units

Either include in LPD calculations or provide 75% High Efficacy lighting.

Dwelling Units

No requirement in state code. NYC code of 2014 requires that 75% of lights must be High Efficacy with no LPD option.

Sleeping Units

Must include in LPD calculations.

Dwelling Units

No requirement.

Sleeping Units

Switch in every room.

Hotel and motel guest rooms require OS or captive key switch + OS in bathrooms.

Dwelling Units

No requirement if 75% of lighting is High Efficacy. Otherwise meet all requirements of commercial energy code.

Sleeping Units

OS in all rooms < 300sf. Switch in all other rooms.

Hotel and motel guest rooms require OS or captive key switch.

• Decorative lighting allowance of 1.0 W/sf is added to match Standard 90.1.

• Lighting power densities are reduced slightly.

• Lighting controls requirements have been reorganized for clarity.

• Daylight responsive controls are now required (more on this later).

• Façade lighting allowance is now based on the size of the building (rather than the illuminated façade area).

• Exterior lighting “setback” is now required.

• Lighting power densities are reduced slightly.

• Lighting controls requirements reorganized into a table.

• Daylight responsive controls will now be required in both the primary and secondary daylight zones (more expansive than before).

• Functional testing (commissioning) requirements are more robust.

• Lighting power densities are identical, including decorative and retail lighting allowances (decorative allowance added back to the IECC this code cycle).

• Lighting controls requirements are very similar, but expressed in very different ways (90.1 now has a table).

• 90.1 requires occupancy sensors in parking garages and stairwells.

• Daylight responsive controls requirements are more complex and costly in 90.1.

• 90.1 includes RCR factors and controls factors. Useful for unusual situations or for running up LEED points.

• 90.1 is more complex, but also more flexible

Incorporates “additional efficiency package” options (for new construction only). The most commonly selected option requires a 10% reduction in lighting power.

• Requires automatic receptacle control for office spaces.

• Includes voltage drop restrictions which are quite expensive for high-rise residential and hotels.

• Bi-level switching is required almost everywhere.

• Daylight responsive control requirements are more extensive, complicated, and costly.

• Occupancy sensors are required for stairwells and parking garages.

Occupant sensors required in:

1. Classrooms/lecture/training rooms.2. Conference/meeting/multipurpose rooms.3. Copy/print rooms.4. Lounges.5. Employee lunch and break rooms.6. Private offices.7. Restrooms.8. Storage rooms.9. Janitorial closets.10. Locker rooms.11. Other spaces 300 square feet or less that are enclosed by floor-to-ceiling

height partitions.12. Warehouses.

Must be manual-on, except in restrooms.

Occupant sensors required in :

1. Classrooms/lecture/training rooms.2. Conference/meeting/multipurpose rooms.3. Copy/print rooms.4. Lounge / break room.5. Offices less than 250 sf.6. Restrooms.7. Storage rooms 50-1,000 sf.8. Locker rooms.9. Parking garages.10. Performing arts theater dressing rooms.11. Retail facility dressing room.12. Stairwells.

Must be manual-on, except in restrooms.

In most other spaces automatic off is required. This will almost always be accomplished by time scheduling (i.e. digital timeswitch).

Don’t forget that a separate manual switch is still required in every room!

Where timeswitch systems are provided, “bi-level” switching is also usually required. “Bi-level” switching is never required where occupant sensors are provided.

“Bi-level” switching is almost always required, even in spaces provided with occupant sensors.

Daylight responsive controls are mandatory!But only where:

1. 150W or more of lighting is installed in the primary daylight zone.

2. There is no overshadowing from adjacent buildings.

3. Windows are large enough to admit a reasonable amount of daylight.

4. The VT of the windows is >20% (IECC).

Primary zone only. Primary and secondary zones.

C103.2 Information on construction documents. Construction documents shall be drawn to scale upon suitable material. Electronic media documents are permitted to be submitted where approved by the code official. Construction documents shall be of sufficient clarity to indicate the location, nature and extent of the work proposed, and shall show in sufficient detail pertinent data and features of the building, systems and equipment as herein governed. Details shall include, but are not limited to, the following:

10. Lighting fixture schedule with wattage and control narrative.

11. Location of daylight zones on floor plans.

Standard 90.1IECC

Technical requirements are very similar:

1. Daylight responsive controls within each space shall be configured so that they can be calibrated from within that space.2. Calibration mechanisms shall be readily accessible.3. Two control steps between full on and full off (90.1).4. Where located in offices, classrooms, laboratories and library reading rooms, daylight responsive controls shall dim lights continuously from full light output to 15 percent of full light output or lower (IECC).5. Daylight responsive controls shall be capable of a complete shutoff of all controlled lights.

6. Lights in secondary daylight zones controlled separately from lights in primary daylight zones (90.1).

C104.2.6 Final inspection. The building shall have a final inspection and shall not be occupied until approved. The final inspection shall include verification of the installation and proper operation of all required building controls, and documentation verifying activities associated with required building commissioning have been conducted and findings of noncompliance corrected. Buildings, or portions thereof, shall not be considered for a final inspection until the code official has received a letter of transmittal from the building owner acknowledging that the building owner has received the Preliminary Commissioning Report as required in Section C408.2.4.

C408.3.1 Functional testing. Prior to passing final inspection, the registered design professional shall provide evidence that the lighting control systems have been tested to ensure that control hardware and software are calibrated, adjusted, programmed and in proper working condition in accordance with the construction documents and manufacturer's instructions. Functional testing shall be in accordance with Sections 408.3.1.1 and C408.3.1.2 for the applicable control type.

C408.3.1.3 Daylight responsive controls. Where daylight responsive controls are provided, the following shall be verified:1. Control devices have been properly located, field calibrated and set for accurate

setpoints and threshold light levels.2. Daylight controlled lighting loads adjust to light level set points in response to

available daylight.3. The locations of calibration adjustment equipment are readily accessible only to

authorized personnel.

SECTION C406ADDITIONAL EFFICIENCY PACKAGE OPTIONSC406.1 Requirements. Buildings shall comply with at least one of the following:I. More efficient HVAC performance in accordance with Section C406.2.2. Reduced lighting power density system in accordance with Section C406.3.3. Enhanced lighting controls in accordance with Section C406.4.4. On-site supply of renewable energy in accordance with Section C406.5.5. Provision of a dedicated outdoor air system for certain HVAC equipment in accordance with Section C406.6.6. High-efficiency service water heating in accordance with Section C406. 7.

C406.3 requires a 10% wattage reduction.C406.4 is too complicated. No project will ever comply with this.

9.4.4 Functional Testing (continued).

The construction documents shall state the party who will conduct and certify the functional testing. The party responsible for the functional testing shall not be directly involved in either the design or construction of the project and shall provide documentation certifying that the installed lighting controls meet or exceed all documented performance criteria. Certification shall be specific enough to verify conformance.

All building facade and landscape lighting shall be automatically shut off between midnight or business closing, whichever is later, and 6 a.m. or business opening, whichever comes first, or between times established bythe authority having jurisdiction.

Lighting not specified above and lighting for signage shall be controlled by a device that automatically reduces the connected lighting power by at least30% from 12 midnight or within one (1) hour of the end of business operations, whichever is later, until 6 a.m. or business opening, whichever is earlier.

(Lighting connected to occupant sensor is generally exempt from the above requirements.)

Exterior Lighting Power Densities Depend on the Lighting Zone

Lighting Zones are not negotiable in NYC
