History of the CodeHistory of the Code
Florida Energy Code
In 2001 the Energy Conservation and Protection Act mandated that all states adopt a commercial energy code (ASHRAE 90.1-1999 or something more stringent for Energy standards)
In 2001 Florida adopted only the Power Allowance portion of ASHRAE 90.1
In 2004 Florida adopted their own code, calling it “The Florida Building Code, Chapter 13-Florida Energy Efficiency for Building Construction 2004” (which remains very similar to ASHRAE 90.1). This code was expanded to include both the Power Allowance and the Lighting Control sections
In 2007 the code was revised and published but not yet adopted
On March 1st of 2009, the revised (2007) Florida Energy code was adopted complete with the 2009 Glitch amendments in their legislative format
This is the Law !!!

above grade- Interior & Exterior Lighting
Alterations & RenovationsAlterations & Renovations• Generally treated as New Construction• Replacement of lighting systems must comply• New or replacement control devices must comply
11
13-415: Applicable Areas13-415: Applicable Areas
Florida Energy Code
This section of Chapter 13 shall apply to the following:
1. Interior Spaces of buildings;
2. Exterior building features, including facades, illuminated roofs, architectural features, entrances, exits, loading docks, and illuminated canopies; and
3. Exterior building grounds lighting provided through the building’s electrical service.
12
13-415: Exempt Areas13-415: Exempt Areas
Florida Energy Code
1. Emergency lighting that is automatically off during normal building operation (ex: emergency lighting bug-eyes, recessed ceiling drop down emergency units, etc.)
2. Lighting within living units (ex: individual condo units)
3. Lighting that is specifically designated as required by a health or life safety statute, ordinance, or regulation(ex: NFPA 101 – Life Safety states stairs must have 10fc of lighting and lighting for that purpose would be exempt.)
4. Decorative gas lighting systems
5. Historic buildings, Federally Mandated buildings, and buildings with a total power density of <1W/ft2
* The following are exempt from both the Power Allowance & Controls…
13
Mandatory: Types of ControlsMandatory: Types of Controls
Florida Energy Code
13-415.1.AB.1.1 Automatic Lighting Shutoff
• Required if building is over 5,000 ft2
• Required to control lighting in all spaces (unless exempt)
• (3) Options for Controls:
1. A scheduled basis using time-of-day operated control device that turns lighting off at specific programmed times (Dimming or Relay System with Low Voltage Switches in spaces)- controls ≤ 25,000ft2 or not more than (1) floor
2. Occupant Sensor (max setting of 30 min.)
3. Signal from another control or alarm device that indicates the area is unoccupied
* You can mix and match the above techniques
14 Florida Energy Code
Clarification per the DOE:- A building is clarified as a “Building area
surrounded by exterior walls or fire walls.”
Ex: If you have a 10,000 square foot strip mall, with (5) 2,000 square foot tenants, and there are fire walls in between each tenant, you DO NOT need to meet the automatic shutoff requirements for each tenant.
Mandatory: Types of ControlsMandatory: Types of Controls
Ex: If you have a 10,000 square foot, 3-story office building, with (4) 2,000 square foot tenants and 2,000 square feet of common area you DO need to have a control system for the tenants and the building common spaces.
The following interpretation is per the U.S. Department of Energy, Building Energy Codes Program available online at:
* Per the DOE, The intent of the code is to apply to business entities where the whole building control is practical (however, up to local electrical plan reviewer interpretation)

Mandatory: Control ExceptionsMandatory: Control Exceptions
Florida Energy Code
13-415.1.AB.1.1 Automatic Lighting Controls:
Exceptions:
a. Lighting intended for 24-hour operation. (ex: 24-hour pharmacy, 24-hour shift manufacturing facilities, etc.)
b. Lighting in spaces where patient care is rendered. (ex: hospital rooms, assisted living suites, etc.)
c. Spaces where an automatic shutoff would endanger the safety or security of the room or building occupant(s).(ex: mechanical and electrical equipment room, operating room, dental suites, workshops, etc.)
16Florida Energy Code
13-415.1.AB.1.2 Space Control:
• Each space enclosed by ceiling-height partitions shall have at least one control device to independently control the general lighting within a space.
• Each control shall be capable of overriding any time-of-day scheduled shut-off control for no more than 4 hours
• In ≤10,000 ft2 spaces, each control can serve a max of 2,500 ft2
• In > 10,000 ft2 spaces, each control can serve a max of 10,000 ft2
Mandatory: Indiv. Space Mandatory: Indiv. Space ControlsControls
17Florida Energy Code
13-415.1.AB.1.2 Space Control:
• Controls can be activated:• Automatically by sensing an occupant (oc. sensor) or• Manually by an occupant (oc. sensor with an override
button or a low voltage “smart” switch tied to a relay panel)
• Each manual device shall be readily accessible and located so the occupants can see the controlled lighting.
Exceptions:
• Remote locations are permitted where security or safety are a concern• Remote control must be labeled to identify the controlled lighting• Remote control must have an indicator pilot light on or next to the
device

Mandatory: Indiv. Space Mandatory: Indiv. Space ControlsControls
Florida Energy Code
13-415.1.AB.1.2 Space Control:
• Occupancy Sensors, that turn lights off within 30 min. of an occupant leaving the space are required in the following specific spaces:
(1) Certain Classrooms (2) Conference/Meeting Rooms(3) Employee Lunch & Break Rooms* Reasoning: Because these spaces are rarely used, an occupancy sensor will save more energy than
another type of control
• If you put an occupancy sensor in these spaces, these spaces are not required to be connected to other automatic lighting shutoff controls.
• This requirement does not apply to spaces with multi-scene control, shop classrooms, laboratory classrooms, and preschool through twelfth grade classrooms. (They are treated as any other space & require (1) of the (3) types of mandatory controls!!!)
Exceptions:
19Florida Energy Code
13-415.1.AB.1.3 Additional Control:
• Controls are required in the following cases:
• Hotel and motel guest rooms lighting. Hotel and motel guest rooms and guest suites shall have a master control device at the main room entry that controls all permanently installed luminaires and switched receptacles.
(ex: A card reader that requires you to insert your card when you enter the room in order to turn the lights on. Or a master switch which overrides all other switches in the space. )
• Separate controls are required in the following cases: (if additional to ambient lighting)
• Display or accent lighting. • Case Lighting. Lighting in cases used for display purposes shall have a
separate control device.• Task Lighting. Supplemental task lighting shall have a control device
integral to the luminaires or be controlled by a wall mounted control device provided the control device is readily accessible and located so that the occupant can see the controlled lighting.
• Non-visual lighting. Lighting for nonvisual applications, such as plant growth and food warming.
• Demonstration Lighting. Lighting equipment that is for sale or for demonstration in lighting education.
• Exterior Lighting > 100 Watts must also be > 60 lumens/watt
• Exception: the luminaire is controlled by a motion sensor or is exempt under Section 13-415.0 or Section 13-415.AB.1.3)

Mandatory: Tandem WiringMandatory: Tandem Wiring
Florida Energy Code
13-415.1.AB.3 Tandem Wiring:
• This section of the code must only be adhered to if Magnetic ballasts are used (T12 lamps) because magnetic ballasts work best if driving two lamps, not one
• One of several exceptions to this section of the code is to use an electronic ballast
• The interior lighting power allowance for a building or a separately metered or permitted portion of a building shall be determined by the:
Space by Space Method – described in section 13-415.B.1
• Trade-Offs of interior lighting power allowance among portions of the building for which a different method of calculation has been used are not permitted
• Installed interior lighting power must be < than the Allowed interior lighting power
26Florida Energy Code
13-415.AB.5.1 Installed Interior Lighting Power
• Exceptions:
- The 15 Items listed in the next few slides shall NOT be included in BOTH the lighting power allowance and the installed interior lighting power
- However…- the lighting listed must be in addition to the general lighting - the lighting listed must be independently controlled
Screw Based Medium Socket Incandescents & Halogens– maximum labeled wattage of the luminaire
Luminaires with Ballasts, Drivers or Transformers – max. UL labeled wattage of lamp/ballast/driver combination or transformer
Line Voltage Track – max. wattage of luminaires in the system or a min. of 30W per linear foot (whichever is greater)

Prescriptive: Calculation Methods Prescriptive: Calculation Methods 13-415.B.1 Space-By- Space Method of Calculating Interior Lighting Power Allowance (LPA)
1.Determine the appropriate building type from table 13-415.B.12.For each space enclosed by partitions 80 % or greater than the ceiling height determine the floor area3.Determine the LPA by using the columns designated space-by-space.4.Multiply the floor area (s) times the allowed Lighting Power Density (LPD) for the space type that most closely represents the proposed use of the space5.The product is the LPA for the space6.The interior LPA is the sum of LPA’s for all spaces
Note: You can go to the IESNA website to see how ASHRAE and IESNA came up with the LPD for each space.
Note: Tradeoffs of Spaces are Allowed (see 13-415.B.1.4) provided that the total installed interior lighting power does not exceed the interior lighting power allowance.
