Richard's Lighting Retrofit Rules

Richard’s Lighting Retrofit Rules are taken from Richard R. Vaillencourt’s book, Simple Solutions to Energy Calculations. (The word, "retrofit", here refers to the process of replacing older lamps, ballasts, fixtures, switching mechanisms, etc. with newer, more efficient lighting products in order to reduce the usage of electricity.)

Lighting Rule #1: You can never save more energy than shutting it off.

Lighting Rule #2: There is at least one person who won’t like it.

Lighting Rule #3: Always retrofit lighting at night.

Lighting Rule #4: The occupancy sensor will turn the lights off when the company president is in the bathroom.
