Top Engineers: Digital Billboards Use Less Energy 
(Washington) – Digital billboard energy consumption has dropped dramatically in the last four years, according to an independent analysis of meter readings by engineers at the Louis Berger Group (LBG).

LBG, a worldwide consulting firm based in Morristown, NJ, said energy consumption by 14x48 foot digital bulletins has declined an average 61 percent in the last four years. Energy use by digital posters (12x24 foot) has dropped an average 40 percent in the same period.

OAAA President & CEO Nancy Fletcher commented, “The outdoor advertising industry is committed to corporate social responsibility and community investment, as evidenced by the findings in this analysis. Digital billboard companies continually strive to enhance product offerings to ensure they are both effective and efficient, and reducing energy consumption is obviously a top priority.”

LBG evaluated meter readings for digital billboards throughout the country, finding these factors:
 
  • Brightness controls reduce brightness at night, reducing energy consumption and costs.
  • Early models included air conditioning to cool electronic equipment. Improved climate resistance of newer equipment has made the need for air conditioning obsolete. In lieu of air conditioning, current digital billboards use air circulation fans, which require less power.
  • Actual consumption is 75 percent or less of capacity.

Nationwide, there are approximately 2,400 digital billboards, out of an estimated 400,000 total billboards.

The digital billboards analyzed by the engineers were made by US manufacturers Daktronics and Young Electric Sign Company (YESCO). The LBG review of energy consumption was sponsored by the Outdoor Advertising Association of America (OAAA).
