Loudoun County Public Schools (LCPS), located 36 miles outside of Washington D.C., encompasses over 9.6 million square feet of building space and provides instruction to over 68,000 K-12 students. LCPS is the fourth largest school system in the Commonwealth of Virginia and has been one of the fastest growing school systems in the nation for many years; rapid growth is expected to continue well into the future. LCPS aims to increase energy efficiency and promote effective stewardship of public resources without impacting the educational environment. This energy use philosophy began in 1993, when LCPS entered into a partnership with Cenergistic, formerly Energy Education, Inc., to implement a comprehensive energy conservation program. In 1998, LCPS became an ENERGY STAR partner and began utilizing the platform of ENERGY STAR tools, resources, and technical information to improve and enhance existing energy efficiency and conservation efforts.
LCPS has been recognized by EPA as an ENERGY STAR Top Performer for achieving an average ENERGY STAR energy performance score of 75 across its portfolio of buildings. In 2009, LCPS was recognized by EPA as an ENERGY STAR Leader for improving its portfolio-wide energy performance by 10 percent compared to a 2000 baseline. More than half of all LCPS buildings earned the ENERGY STAR, a mark of superior energy performance. The district was named an ENERGY STAR Partner of the Year for 2010 and 2011, and earned a Sustained Excellence Partner of the Year award for 2012. Earning recognition as a Top Performer has been a rewarding process, requiring the participation of students, staff members, community members, and business partners. LCPS's commitment to the environment is expressed through the actions it has taken over the years. Compared to its baseline year, the district currently prevents the annual emissions of more than 13,500 metric tons of carbon dioxide, which is equivalent to the carbon sequestered by more than 347,400 tree seedlings planted and grown for 10 years.
