Tulsa Public Schools is an urban public school district serving approximately 36,000 students in grades pre-kindergarten through 12 in over 80 schools. Tulsa Public Schools implemented its largest ever energy saving program in partnership with Entegrity. Each of the district’s schools received cutting-edge LED lighting upgrades. These improvements will yield substantial savings for the district, reduce annual lighting electricity use by an estimated 40%, and improve the learning environment by increasing light levels and providing greater control to teachers in the classroom.
