|DELTA Portfolio: DeGraff St. Industrial Center, Office and Small Manufacturing|
The DeGraff St. Industrial Center is an old mill that has been renovated into office and small manufacturing space. The lighting uses T8 fluorescent lamps and electronic ballasts. Galvanized steel stovepipe incorporated into light valances helps to retain the industrial character of the mill. This project takes advantage of plentiful daylight.
|DELTA Portfolio: SONY Disc Manufacturing Center, Manufacturing Facility|
Sony's advanced manufacturing facility for digital optical disks requires lighting designed for good task visibility and visual comfort for its employees. The project includes lighting for clean room manufacturing, packaging, warehousing, and shipping/receiving areas. Energy-efficient lighting products reduce energy consumption while creating bright, visually stimulating spaces to help keep shift workers alert before sunrise.
|DELTA Portfolio: Staples Distribution Center|
High-density warehousing and distribution center with low-energy lighting controlled by occupancy sensors.

|Field Test DELTA Snapshots: Alternative Technologies for Construction Lighting|
Although conventional construction lighting often consists of strings of incandescent lamps in a simple cage, several alternative lighting technologies are now available that save energy and are acceptable to construction site workers. In this publication, the LRC evaluates conventional construction lighting and three alternative technologies: screw-base compact fluorescent lamps, screw-base LED lamps, and a low voltage LED system. This study compares worker acceptance, installation and maintenance, and energy performance of the four lighting technologies.

|Demand-Response, Load-Shedding Ballast System|
Demand-response building systems are an important component of electricity load management programs. Until recently, the inclusion of lighting into any demand response strategy has involved turning off banks of lights manually or through a building management system with complicated distribution and/or control wiring. With its partners, the LRC developed, demonstrated and evaluated a cost-effective, load-shedding ballast system to command the lighting to dim at times of peak electric demand, without installing additional wiring.
|Field Test DELTA: T5 Fluorescent High-Bay Luminaires and Wireless Lighting Controls|
The DELTA research team field-tested T5 fluorescent luminaires and wireless motion-sensor lighting controls at a distribution center warehouse in Albany, N.Y. The field test in this high-bay environment included illuminance measurements, energy savings calculations, verification of system component operation, and worker feedback.
|Field Test DELTA: Daylight-Harvesting Switch|
The DaySwitch® is a simple daylight-harvesting switch designed to turn off electric lights when plentiful daylight is available. The LRC developed the DaySwitch, collaborated with manufacturing partners to build prototypes, and demonstrated the device in a wide range of locations throughout the Rensselaer campus. This publication summarizes the product features and demonstration results.
