pertaining to new, renovated and existing commercial building
lighting. Compare and evaluate control requirements pertaining to
new, renovated and existing commercial building lighting.
Identify and differentiate between indoor and outdoor lighting
energy related requirements.
-
*History of the CodeFlorida Energy CodeIn 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 sectionsIn 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 !!!

Energy Systems: Mechanical, Electrical, & Illumination
Systems forNew building constructionAdditionsAlterationsAny change
in building configuration
-
*Florida Energy Code - SectionsFlorida Energy Code
This code is a statewide code and shall not be made more
stringent or lenient by local government.
-
*New Construction & AdditionsFlorida Energy Code
The provisions of this chapter apply to the Lighting Power
Density and the Control requirements of:All commercial occupancy
buildings of any sizeAdditions to existing commercial occupancy
buildingsMultiple-family residential buildings 4 stories or more
above gradeInterior & Exterior Lighting
Alterations & Renovations
Generally treated as New ConstructionReplacement of lighting
systems must complyNew or replacement control devices must
comply
-
*13-415: Applicable AreasFlorida Energy CodeThis section of
Chapter 13 shall apply to the following:
Interior Spaces of buildings;
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
buildings electrical service.
-
*13-415: Exempt AreasFlorida 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
-
*Mandatory: Types of ControlsFlorida Energy Code13-415.1.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:
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
-
* Florida Energy CodeClarification 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 ControlsEx: 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:
http://www.energycodes.gov/training/onlinetraining/video_standard9012004_lighting.stm
* 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 ExceptionsFlorida Energy Code13-415.1.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.)
-
*Florida Energy Code13-415.1.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 ft2In > 10,000 ft2 spaces, each control can serve a max of
10,000 ft2
Mandatory: Indiv. Space Controls
-
*Florida Energy Code13-415.1.AB.1.2 Space Control:
Controls can be activated:Automatically by sensing an occupant
(oc. sensor) orManually 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
concernRemote control must be labeled to identify the controlled
lightingRemote control must have an indicator pilot light on or
next to the device
Mandatory: Indiv. Space Controls
-
*Mandatory: Indiv. Space ControlsFlorida Energy
Code13-415.1.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:
Certain Classrooms Conference/Meeting RoomsEmployee 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:
-
*Florida Energy Code13-415.1.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.
Mandatory: Additional Controls(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. )
-
*Mandatory: Additional ControlsFlorida Energy
Code13-415.1.AB.1.3 Additional Control:
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.

*Florida Energy CodePrescriptive: Calculation Methods 13-415.B.1
Space-By- Space Method of Calculating Interior Lighting Power
Allowance (LPA)
Determine the appropriate building type from table 13-415.B.1For
each space enclosed by partitions 80 % or greater than the ceiling
height determine the floor areaDetermine the LPA by using the
columns designated space-by-space.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 spaceThe product is
the LPA for the spaceThe interior LPA is the sum of LPAs 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.
