Learning Objectives Students will; • Obtain a working knowledge of Chapter 13 of the Florida Building Code. • Compare and evaluate power limiting (watts/sq. ft) requirements 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. Florida Energy Code 5
History of the 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 1 st of 2009, the revised (2007) Florida Energy code was adopted complete with the 2009 Glitch amendments in their legislative format This is the Law !!! Florida Energy Code 6

13 -415: Applicable Areas 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. Florida Energy Code 11
13 -415: Exempt Areas * The following are exempt from both the Power Allowance & Controls… 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 10 fc of lighting and lighting for that purpose would be exempt. ) Decorative gas lighting systems 4. 5. Historic buildings, Federally Mandated buildings, and buildings with a total power density of <1 W/ft 2 Florida Energy Code 12
Mandatory: Types of Controls 13 -415. 1. AB. 1. 1 Automatic Lighting Shutoff • Required if building is over 5, 000 ft 2 • 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, 000 ft 2 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 Code 13
Mandatory: Types of Controls Clarification per the DOE: - A building is clarified as a “Building area surrounded by exterior walls or fire walls. ” 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_standard 9012004_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) 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. 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. Florida Energy Code 14
Mandatory: Control Exceptions 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).

Mandatory: Indiv. Space Controls 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 Florida Energy Code 17
Mandatory: Indiv. Space Controls 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 Exceptions: • 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!!!) Florida Energy Code 18
Mandatory: Additional Controls 13 -415. 1. AB. 1. 3 Additional Control: • Controls are required in the following cases: • Hotel and motel guest rooms lighting.

(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. ) Florida Energy Code 19
Mandatory: Additional Controls 13 -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 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.
