Commercial space in the U.S. covers 60 billion square feet with 1 billion light fixtures—most of which aren't equipped with automated lighting controls. It would be expensive to rewire those spaces for sophisticated lighting controls, but wireless systems could provide an effective solution.

Daylight harvesting systems promise energy savings and peak demand reduction, along with harder-to-quantify benefits of a better indoor environment. Unfortunately, these systems often fail to live up to their potential. We look at what can go wrong and how to use these systems correctly.

This report looks at the capabilities, benefits, and costs of a relatively new lighting control approach based on digitally addressable lighting interface (DALI) technology. DALI offers users the ability to tailor local lighting conditions to their individual needs.
