Hypothetical situation: You’re looking to purchase a new car. With rising gas prices, fuel efficiency is an important consideration. But would you overlook all other aspects of a car’s performance to get the best fuel efficiency possible? Probably not. “No one would buy a car that does not go very fast and takes a long time to get to maximum speed”. Why then would you do that with your lighting system? If the energy efficiency of a lighting system overshadows the quality of the lighting, the system is inadequate.
Engineers, Lighting Designers and Architects have to practice a similar balancing act to achieve an energy efficient lighting system that also satisfies the needs of building occupants. If you approach it from a pure energy standpoint you might be far from happy with the results. Simply changing light bulbs may be a low-hanging fruit option, but if you don’t look at it holistically, the lighting quality suffers.” Looking only at energy efficiency may initially help the bottom line, but in the long term, looking at lighting systems both from energy-related metrics as well as quality-of-light metrics will save money and keep the building occupants happy.
