Over-Illumination Waste

Basics

• This is the Energy Waste from leaving lights on, or lighting a space inefficiently

Forms

Leaving Lights On

• Either due to conveince or user error lights can be left on
• Also leaving them on during the day can be a source
• Thus the device is consuming energy when it may not have to

Innefficient Lighting

• This can be either
  • Inneficient Sources (see Luminous Efficacy )
  • Inneficient Light Distribution

Solutions

Leaving Lights On

• PSAs and User Awareness
• Automatic Light Switches

Inneficient Lighting

• Use leds whenever possible
• POSSIBLY Sulfur Lamps in high lumen applications (if developed more)
• Design Considerations:
  • How much light is really needed
  • Multiple Levels of Lighting (Instead of Light Room or Dark Room, a lit table and dark room, or lit corner via table lamp etc, and using these accordingly)
  • Night Modes (Dim Lights according to time of day, and have dedicated nightlights for navigation as it gets darker rather than having to fully light the room)
