In 1992, the EPA introduced ENERGY STAR as a voluntary labeling program designed to identify and promote energy-efficient products to reduce greenhouse gas emissions. Computers and monitors were the first labeled products. The EPA now extends the label to cover new homes, schools, commercial and industrial buildings. Numerous Loudoun County Public Schools buildings have been awarded an ENERGY STAR label.
The ENERGY STAR is the national and official symbol of recognition of energy efficiency, and it distinguishes LCPS for its accomplishments in Energy Management and the achievement of a rating for superior energy and environmental performance at those sites.
