Energy Efficiency Measures for Lighting

Replace inefficient lighting, including:
- incandescent lamps
- halogens
- T-12 fluorescents
- magnetically ballasted fluorescents
- mercury vapor lamps
When replacing, options include replacing the ballast, tube, or the entire fixture. (Note that replacing a whole fixture improves the quality of lighting.)
Replace flickering, dim, and burned-out lamps
Clean diffusers, lenses, and lamps
Re-lamp the whole building on a regular schedule
Trim bushes and trees away from outdoor lighting

Identify spaces that are over illuminated, these are areas where it's possible to de-lamp the lighting system.
See this table of expected footcandles in a space, based on the type of space.
Install or commission lighting controls, including:
- timers
- occupancy sensors
- daylighting controls
Recommend task lighting to increase lighting only where it's needed.
