Visualizing Architectural Lighting

• Motivation
• improved visual environments
• energy

• Various people and potential applications
• Focus is on daylight integration by the
  lighting designer

Distributed Visualization

• Individuals are influenced by organizations,
  policy, training, design tools, etc.
• Visualization systems need to reconcile these
  external factors

Pilot Study

• Practicing lighting designer (X yrs)
• Reviewing a simplified visualization plot
• Office design context

Results
BEFORE
AFTER

• Single lighting system(3 wall sconces)
• Balance light with room geometry
• Static visual field

• Three lighting systems (daylight 2 electric)
• Electric light placement corresponds to daylight
• Occupant as part of solution

Innovation, Part II

• New techniques will happen

SAMSON Data (30x as precise)

• But who/when/how/why?
