Return-to-office surveys have revealed that environmental conditions, specifically lighting and the lack of flexible, accessible lighting controls, contribute to workplace inequity and impede employee performance. We intend to provide clear lighting design guidance to better accommodate a changing, diverse workforce and their space use needs. Presenters will review findings from two research studies involving a diverse group of users – one with participants with self-identified, functional visual limitations, and another group representative of 2020 US Census workplace demographics – and apply designing to the edges principles to help our industry deliver a better lighting and controls experience for all.

Learning Objectives

  • Participants will be able to identify the most frequently prioritized general area lighting quality requirements.
  • Participants can name the second most disabling workplace condition – after lower back pain – according to the US Census. Hint: photo sensitivity is a symptom.
  • Participants will understand how to “design to the edge” to satisfy diverse lighting requirements.
  • Participants will leave armed with the knowledge of lighting quality and granularity of control requirements to better support an equitable, accessible end-user experience.
