12 CORE Principles for Healthy Building Design

CORE Principle 06

Circadian & Healthy Lighting Systems

Lighting affects much more than our ability to see.

Natural daylight and artificial lighting influence the visual environment, comfort, sleep-wake patterns, and how interior spaces are experienced throughout the day.

SENERGY360 coordinates lighting with the architecture, electrical system, interior design, glazing, shading, and automation strategy.

SENERGY360 helps guide:

  • Natural daylight
  • Window and shading coordination
  • Circadian-responsive lighting
  • Tunable lighting systems
  • Low-flicker fixtures and drivers
  • Spectrum and color-temperature considerations
  • Ambient, task, accent, and indirect lighting
  • Nighttime navigation lighting
  • Glare control
  • Lighting controls and automation
  • Exterior light-pollution reduction

Healthy lighting should work with the natural day-night cycle rather than fight against it.

Every principle is stronger when the other eleven are in the room.

SENERGY360 coordinates all twelve from early design through final verification.
