Wylie Independent School District (WISD), located in Collin County, Texas, serves more than 13,000 students in facilities encompassing more than 1.9 million square feet of space. The mission of the district is to provide an education of excellence for all of its students so they may function effectively, successfully, and productively in society. WISD values energy efficiency and continually educates its students and staff members on energy conservation. In 2009, WISD became an ENERGY STAR Partner, and two of the district's schools earned the ENERGY STAR. Since then, 17 schools have earned ENERGY STAR certification.
Wylie Independent School District has been recognized by EPA as an ENERGY STAR Leader for improving its energy performance by more than 10 percent compared to a 2007 baseline and as a Top Performer for achieving an average ENERGY STAR energy performance score of 82 across its portfolio of buildings. These achievements have been accomplished by implementing lighting retrofits, improving the control of energy management systems, replacing roofing and insulation, and educating students and staff members on energy efficiency. In EPA's 2011 National Building Competition, the district's oldest school, Hartman Elementary, achieved second place in its category. The school finished fourth amongst all buildings. Recognition for these achievements goes to the Maintenance and Facilities Department, students, and staff members for their hard work and ongoing support. The ENERGY STAR program has helped the district save more than $250,000 over a two-year period. Compared to its 2007 baseline, the district is preventing the emissions of more than 2,400 metric tons of carbon dioxide annually, which is equivalent to the carbon sequestered by more than 63,300 tree seedlings planted and grown for 10 years.
