DELTA Portfolio
	DELTA Portfolio: 450 South Salina Street, Office Building Originally constructed in 1911 as a furniture store, this building was gutted and remodeled to house government and professional offices in 1992-93. Occupancy sensors control most lighting systems, which include 2'x4' troffers with parabolic louvers and T8 lamps, cove uplights with long twin-tube fluorescent lamps, and wall washers with compact fluorescent lamps.
	DELTA Portfolio: Prudential Healthcare, Office Building In this medical and dental claims processing center, designers wanted to provide low, balanced brightness for viewing VDTs; keep costs low and maintenance simple; and provide a pleasant, appealing environment. Linear fluorescent uplighting, individual task lights, and pliable sconces provide some of the lighting for the open office space with partitioned workstations, conference rooms, mailroom, and cafeteria.
	DELTA Portfolio: SONY Disc Manufacturing, Administration and Support Spaces The lighting in the administration and support space of this huge facility was designed to provide task visibility with a minimum of glare, while enhancing the architectural design and creating visual interest. Areas discussed include open offices, corridors, the dining area, and a wellness center. Many of these areas utilize daylight controls.
	DELTA Portfolio: Sacramento Municipal Utility District, Office Building This electric utility's customer service offices feature a direct/indirect T8 fluorescent lighting system using dimmable ballasts and photosensor controls. Workstations have flexible-arm compact fluorescent task lights for supplemental lighting. The building envelope features light shelves, interior sails, and skylights.
DELTA Snapshots
	DELTA Snapshots: Corridor Lighting, Issue 1 The Connecticut Children's Medical Center wants its lighting to provide visual variety for the hospital's patients and their parents. In addition, the lighting must reinforce the architectural design, focus attention on the hospital's artwork rather than the luminaires, minimize glare, and provide good color rendering. This Snapshot illustrates a clever way to illuminate a hospital corridor using indirect lighting.
	DELTA Snapshots: Exit Signs The total annual energy cost for exit signs in the U.S. using incandescent lamps is approximately $1 billion. Switching to ENERGY STAR-labeled LED exit signs will reduce energy and relamping costs, plus the pollution power plants produce. This Snapshot profiles exit sign installations in the U.S. Post Office in Eugene, Oregon, and at the Lighting Research Center in Watervliet, N.Y.
	DELTA Snapshots: Office Lighting Indirect lighting for open-plan offices is an effective approach to providing a comfortable, low-glare office environment. This Snapshot features a creative solution that is flexible and functional. The application provides uniform illumination throughout the open office area, good color quality for graphic layout work, and a consistent visual design that ties all work areas together. The application uses long-life lamps for reduced maintenance.
	DELTA Snapshots: Private Office Lighting Controls Properly designed and installed lighting controls can reduce energy costs and increase employee satisfaction. This Snapshot gives the results of a study evaluating employee satisfaction with automatic and manual lighting controls, the effect of manual lighting control accessibility on users, and the effectiveness of automatic and manual lighting controls for saving energy. Manual dimming, on/off control strategies, and occupancy sensors in private offices are all considered.
