ANSI/ASHRAE/IESNA Standard 90.1-2007 59 interior lighting power shall be based solely on the lighting system with the highest wattage. 9.1.4 Luminaire Wattage. Luminaire wattage incorporated into the installed interior lighting power shall be determined in accordance with the following criteria: a. The wattage of incandescent or tungsten-halogen luminaires with medium screw base sockets and not containing permanently installed ballasts shall be the maximum labeled wattage of the luminaire. b. The wattage of luminaires with permanently installed or remote ballasts or transformers shall be the operating input wattage of the maximum lamp/auxiliary combination based on values from the auxiliary manufacturers? literature or recognized testing laboratories or shall be the maximum labeled wattage of the luminaire. c. For line-voltage lighting track and plug-in busway, designed to allow the addition and/or relocation of luminaires without altering the wiring of the system, the wattage shall be 1. the specified wattage of the luminaires included in the system with a minimum of 30 W/lin ft or 2. the wattage limit of the system? circuit breaker or 3. the wattage limit of other permanent current-limiting device(s) on the system. d. The wattage of low-voltage lighting track, cable conductor, rail conductor, and other flexible lighting systems that allow the addition and/or relocation of luminaires without altering the wiring of the system shall be the specified wattage of the transformer supplying the system. e. The wattage of all other miscellaneous lighting equipment shall be the specified wattage of the lighting equipment. 9.2 Compliance Path(s) 9.2.1 Lighting systems and equipment shall comply with Section 9.1, General; Section 9.4, Mandatory Provisions; and the prescriptive requirements of either a. Section 9.5, Building Area Method; or b. Section 9.6, Space-by-Space Method. 9.2.2 Prescriptive Requirements 9.2.2.1 The Building Area Method for determining the interior lighting power allowance, described in Section 9.5, is a simplified approach for demonstrating compliance. 9.2.2.2 The Space-by-Space Method, described in Section 9.6, is an alternative approach that allows greater flexibility. 9.2.2.3 Interior Lighting Power. The interior lighting power allowance for a building or a separately metered or permitted portion of a building shall be determined by either the Building Area Method described in Section 9.5 or the Spaceby- Space Method described in Section 9.6. 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. The installed interior lighting power identified in accordance with Section 9.1.3 shall not exceed the interior lighting power allowance developed in accordance with Section 9.5 or 9.6. Exceptions: The following lighting equipment and applications shall not be considered when determining the interior lighting power allowance developed in accordance with Section 9.5 or 9.6, nor shall the wattage for such lighting be included in the installed interior lighting power identified in accordance with Section 9.1.3. However, any such lighting shall not be exempt unless it is an addition to general lighting and is controlled by an independent control device. a. Display or accent lighting that is an essential element for the function performed in galleries, museums, and monuments. b. Lighting that is integral to equipment or instrumentation and is installed by its manufacturer. c. Lighting specifically designed for use only during medical or dental procedures and lighting integral to medical equipment. d. Lighting integral to both open and glass-enclosed refrigerator and freezer cases. e. Lighting integral to food warming and food preparation equipment. f. Lighting for plant growth or maintenance. g. Lighting in spaces specifically designed for use by occupants with special lighting needs including visual impairment and other medical and age-related issues. h. Lighting in retail display windows, provided the display area is enclosed by ceiling-height partitions. i. Lighting in interior spaces that have been specifically designated as a registered interior historic landmark. j. Lighting that is an integral part of advertising or directional signage. k. Exit signs. l. Lighting that is for sale or lighting educational demonstration systems. m. Lighting for theatrical purposes, including performance, stage, and film and video production. n. Lighting for television broadcasting in sporting activity areas. o. Casino gaming areas. p. Furniture-mounted supplemental task lighting that is controlled by automatic shutoff and complies with Section 9.4.1.4(d). 9.3 (Not Used) 9.4 Mandatory Provisions 9.4.1 Lighting Control 9.4.1.1 Automatic Lighting Shutoff. Interior lighting in buildings larger than 5000 ft2 shall be controlled with an automatic control device to shut off building lighting in all spaces. This automatic control device shall function on either a. a scheduled basis using a time-of-day operated control device that turns lighting off at specific programmed times?n independent program schedule shall be provided for areas of no more than 25,000 ft2 but not more than one floor?r
