Lexmark International announced recently that its Lexington headquarters saved more than $450,000 in power expenses in 2009 because of energy-efficiency activities.
Part of the savings came from an effort over the past few years to retrofit lighting on the campus, according to the company's recently released 2010 Corporate Social Responsibility Report.
During the first phase in 2007 and 2008, the company replaced lamps and magnetic ballasts of fluorescent light fixtures with higher-efficiency lamps and electronic ballasts. The moves saved $80,000 annually.
A second phase in 2009 has yielded an additional $20,000 in annual savings, as the company reduced the number of lights and installed occupancy sensors.
