DELTA (Demonstration and Evaluation of Lighting Technologies and Applications) is a program to design, evaluate and publicize energy-efficient lighting solutions.

The sites selected contain lighting and controls systems that are evaluated for energy use, human response, cost, how well the technologies work and how easy they are to maintain. Plans, details and color photos illustrate each case study. Combined into a portfolio, the publications illustrate a wide array of effective lighting applications for common building types.

DELTA Publications are available free in PDF format!
