When such a service is not available, seek out local recyclers to reclaim the materials. 1.8 SUSTAINABLE DESIGN REQUIREMENTS 1.8.1 _{Local/Regional Materials} NOTE: Using local materials can help minimize transportation impacts, including fossil fuel consumption, air pollution, and labor. Note: This is optional for Army projects. [Use materials or products extracted, harvested, or recovered, as well as manufactured, within a [800][_____] kilometer [500][_____] mile radius from the project site, if available from a minimum of three sources.] 1.8.2 _{Environmental Data} NOTE: ASTM E 2129 provides for detailed documentation of the sustainability aspects of products used in the project. This level of detail may be useful to the Contractor, Government, building occupants, or the public in assessing the sustainability of these products. NOTE: This is optional for Army projects. [Submit Table 1 of ASTM E 2129 for the following products: [_____].] PART 2 PRODUCTS 2.1 PRODUCT STANDARDS Provide incandescent lighting fixtures conforming to UL 1598. Provide fixtures in hazardous areas conforming to UL 844. Furnish lighting fixtures completely assembled with wiring and mounting devices and ready for installation at the locations noted. Design and equip recessed fixtures in suspended ceilings for installation in the type of ceiling in which the fixture is to be installed. Design fixtures to be supported independent of the ceiling. Equip fixtures with the lamps required. 2.2 _{FLUORESCENT LIGHTING FIXTURES} NOTE: For projects within the United States and its possessions, do not specify hard metric recessed lighting fixtures as the only option. Provide fluorescent fixtures, conforming toUL 1598with electronic ballasts [unless specifically indicated otherwise]. 2.2.1 Fluorescent Lamp Electronic Ballasts NOTE: Electronic ballasts may have system compatibility problems when installed in certain environments. The problems mainly concern the radiated and conducted EMI due to the relatively high switching frequencies inherent in electronic ballasts and possibly due to utilization of the same power source for lighting and other equipment. Shielding technologies today can prevent interference with surroundings, and therefore this is rarely an issue. Environments where electronic ballasts have the potential for EMI are: 1. Libraries or other facilities which utilize magnetic detectors to prevent theft or inventory control. However, it has been reported that electronic ballasts have no impact on the magnetic detectors if the separation distance is greater than 3050 to 4575 mm 10 to 15 feet. This includes distances in all directions through floors, ceilings, and walls. 2. Facilities using high frequency power line carrier (PLC) control systems, such as a central clock system. These PLC systems usually have a 50,000 Hz to 200 kHz carrier frequency which may be affected by the harmonics generated by the electronic ballasts. 3. Areas where sensitive electronic equipment is installed such as hospital critical care units, other areas utilizing sensitive electronic equipment based life support systems, and electronic testing facilities. With proper design considerations, electronic ballasts should provide satisfactory performance even in these and other sensitive areas. The designer must consider fixture location, fixture performance characteristics, manufacturers' recommendations, environmental constraints, etc. in the lighting design. Edit this specification as required to solve specific design problems. Provide electronic ballasts, meeting as a minimum, the following characteristics: a. Provide ballasts complying with UL 935, NEMA C82.11, NFPA 70, and CEC Title 24 unless specified otherwise. Provide 100 percent electronic high frequency type ballasts with no magnetic core and coil components, which provide transient immunity as recommended by IEEE C62.41.1 and IEEE C62.41.2. Design ballast for the wattage of the lamps used in the indicated application. Design ballasts to operate on the voltage system to which they are connected. b. A power factor of 0.95 (minimum). c. Operates at a frequency of 20,000 Hertz (minimum), and is compatible with and not cause interference with the operation of occupancy sensors or other infrared control systems. Provide ballasts operating at or above 40,000 Hertz where available. d. Light regulation of plus or minus 10 percent lumen output with a plus or minus 10 percent input voltage regulation. Ensure ballasts have 10 percent flicker (maximum) using any compatible lamp. e. A ballast factor between 0.85 (minimum) and 1.00 (maximum). Current crest factor - 1.7 (maximum). f. UL listed Class P with a sound rating of "A." g. Include circuit diagrams and lamp connections displayed on the ballast. NOTE: Choose the bracketed option and require programmed start ballasts for Army and Air Force projects. For Navy projects, provide instant start ballasts for areas not subject to frequent switching (i.e., more than once every three hours). Provide programmed start ballasts for areas subject to frequent switching, including all areas controlled by occupancy sensors. Identify fixtures requiring each type on the drawings. h. [Provide instant start ballasts unless otherwise indicated, with programmed start where indicated. Provide instant start ballasts which operate lamps in a parallel circuit configuration that permits the operation of remaining lamps if one or more lamps fail or are removed.][ Provide programmed start ballast unless otherwise indicated.][ Programmed start ballasts may operate lamps in a series circuit configuration. Provide series/parallel wiring for programmed start ballasts where available.] i. Provide programmed start ballasts for compact fluorescent fixtures. j.

PART 3 EXECUTION 3.1 INSTALLATION Ensure all electrical installations conform to IEEE C2, NFPA 70, and to the requirements specified herein. 3.1.1 Lamps NOTE: Indicate all lamp types and colors on the lighting fixture schedule. Deliver lamps of the type, wattage, and voltage rating indicated to the project in the original cartons and installed just prior to project completion. Replace lamps installed and used for working light during construction prior to turnover to the Government if more than 15 percent of their rated life has been used. Test the lamps for proper operation prior to turn-over and replace if necessary with new lamps from the original manufacturer. Provide 10 percent spare lamps of each type from the original manufacturer. 3.1.2 Lighting Fixtures NOTE: Coordinate these requirements with architectural plans and specifications. Ensure requirements for antiterrorism/force protection for fixtures in suspended ceilings are included in and coordinated with Section 09 51 00 ACOUSTICAL CEILINGS by referencing ASTM E 580 seismic requirements in that section. Design lighting fixtures for facilities located in earthquake zones with additional supports and restraining devices as described in Army TI809-04, "Seismic Design for Buildings." Set lighting fixtures plumb, square, and level with ceiling and walls, in alignment with adjacent lighting fixtures, and secure in accordance with manufacturers' directions and approved drawings, in conformance with the requirements of NFPA 70. Mounting heights specified or indicated are to the bottom of fixture for ceiling-mounted fixtures and to center of fixture for wall-mounted fixtures. Obtain approval of the exact mounting for lighting fixtures on the job before commencing installation and, where applicable, after coordinating with the type, style, and pattern of the ceiling being installed. Indepently support recessed and semi-recessed fixtures from the building structure by a minimum of four wires[ or straps][ or rods] per fixture and located near each corner of each fixture. Ceiling grid clips are not allowed as an alternative to independently supported light fixtures. Independently support round fixtures smaller in size than the ceiling grid from the building structure by a minimum of four wires[ or straps][ or rods] per fixture spaced approximately equidistant around the fixture. Do not support fixtures by ceiling acoustical panels. Where fixtures of sizes less than the ceiling grid are indicated to be centered in the acoustical panel, support such fixtures independently and provide at least two 19 mm 3/4 inch metal channels spanning, and secured to, the ceiling tees for centering and aligning the fixture. Provide wires[ or straps][ or rods] for lighting fixture support in this section. Lighting fixtures installed in suspended ceilings are to comply with the requirements of Section 09 51 00 ACOUSTICAL CEILINGS. 3.1.3 Suspended Fixtures NOTE: Coordinate pendant sway bracing details with the architect. The architect may prefer to provide pendant sway bracing details in locations where appearance is important. Provide suspended fixtures with 0.79 rad 45 degree swivel hangers so that they hang plumb and locate with no obstructions within the 0.79 rad 45 degree range in all directions. Provide the stem, canopy and fixture capable of a 0.79 rad 45 degree swing. Brace pendants, rods, or chains 1.2 meters 4 feet or longer excluding fixture, to prevent swaying, using three cables at 2.09 rad 120 degree separation. Provide suspended fixtures in continuous rows with internal wireway systems for end to end wiring and properly aligned to provide a straight and continuous row without bends, gaps, light leaks or filler pieces. Use aligning splines on extruded aluminum fixtures to assure hairline joints. Support steel fixtures to prevent "oil-canning" effects. Provide fixture finishes free of scratches, nicks, dents, and warps, and matching the color and gloss specified. Provide pendants finished to match Provide stainless steel air craft cable. Provide canopies finished to match the ceiling and low profile unless otherwise shown. Ensure maximum distance between suspension points is 3.1 meters 10 feet or as recommended by the manufacturer, whichever is less. [3.1.4 Ballasts [3.1.4.1 Remote Ballasts Mount remote type ballasts or transformers, where indicated, in a well ventilated, easily accessible location, within the maximum operating distance from the lamp, as designated by the manufacturer. ][3.1.4.2 Electronic Dimming Ballasts Provide all electronic dimming ballasts, controlled by the same controller, from the same manufacturer.
