If you own or operate a commercial building, it is very likely you have either looked into retrofitting to LEDs or had a company call on you to talk to you about doing it. In order to have an LED retrofit conducted in your building, the first step is getting an audit performed. After all, you cannot know what to install, what the costs will be, or what you will save in energy without first knowing what actually exists in your facility.
Most people don't ever think about lighting. It's just there. You flip the switch and your lights burst forth with the necessary lumens to help you do your tasks.
Stop for a second and look up and around? How many lights and/or light fixtures do you see? What about the parking lot outside your office? How many parking lot pole lights and/or wallpack lights do you see? Are any of them unnecessary? Is it too dark in some places?
It is likely that an electrical engineer or an electrical contractor designed the lighting system you park your car under and the overhead lighting that you work under every day. Odds are that person was not trained or certified specifically in lighting, much less trained or certified in energy efficient lighting design. What's wrong with electrical engineers and electrical contractors?
