Let There Be Light Control for Productivity

Workers prefer personal control of lighting environment


Workers prefer personal control of lighting environment.

Lighting requirements to enhance productivity and comfort have been proposed for ANSI/ASHRAE/USGBC/IES Standard 189.1-2011.

This proposal addresses subsections and, which require that occupants of certain space types be given some level of control over the light levels in that space.

Citing a research study on the effects of lighting on office workers, the proposal notes “Normally, the persistence and vigilance of office workers will decline over the course of a workday. However, the presence of personal control of their lighting increased subject motivation allowing workers to sustain their performance – they persisted longer on difficult tasks and were more accurate on a task requiring sustained attention.”
