About Us

Since 1994, the DELTA program has produced more than 40 case studies at sites ranging from schools to office buildings to senior housing, along with numerous outdoor locations. The reports are written for lighting specifiers, building managers, architects, and others who design and install lighting, and are available for free download.

Each case study, carefully documented to include sample specifications and dimensions, is evaluated by a consistent methodology addressing energy use, maintenance, environmental impact, occupant acceptance, and performance.

Lessons learned from these evaluations teach lighting specifiers about compatibility of lighting equipment, system performance, and ways to improve their own lighting designs. DELTA reduces a specifier's risk of using new technologies through objective performance evaluation.

Contact Jennifer Brons, Program Director, for more information about collaborating with DELTA.
