LM&M, the official magazine of NALMCO (interNational Association of Lighting Maintenance Companies), published a profile of CES (Contemporary Energy Solutions LLC.) in a story, spotlighting one of the CES's lighting retrofit projects.
Brad Butler, Sales Engineer Manager for CES outlined the project from start to finish, including hurdles such as the inevitable Wisconsin weather.
The story spotlights how earlier this year, a metal storage and distribution facility in Wisconsin decided to upgrade their lighting system. The existing high-pressure sodium fixtures were outdated and didn't provide enough light inside the facility. Additionally, the exterior lighting didn't cover the entire building and parking lot. The facility contacted Contemporary Energy Solutions, an ESCO based in Manitowoc, WI, with whom they had previously worked on revitalizing the office and maintenance areas. CES proposed a complete lighting upgrade for the entire facility, both inside and outside, which would give the building a modern look and provide significant energy savings.
The high-pressure sodium lights that were previously installed were replaced with Orion Energy Systems LED high bays. The new fixtures have a lower wattage of 136W in high-ceiling areas and 68W in low-ceiling areas. Due to the size difference between the old lights and the new fixtures, the LEDs in the high bay area had to be installed lower than the previous fixtures, below the structure of the roof which would have obscured some of the light. In the areas with a lower ceiling, the fixtures were raised as much as possible to maximize storage space and maneuverability.
Butler goes on to explain, “Lighting is such an overlooked factor. It may only be 20% of your utility bill, but it effects every other aspect of a building."
