Lubbock ISD's Energy Specialist Paul Estrada ensures that students, staff, and faculty are comfortable during class time and scheduled activities and that energy is used only as necessary. We work hard to optimize building use and train personnel to control energy use wherever possible. Every energy-using item in the system — including all heating, ventilation, and air conditioning systems, food service facilities, athletic facilities, offices and classrooms, auditoriums, cafeterias, information technology, and computer labs — receives ongoing evaluation for the best, most efficient use of energy while ensuring that the learning environment is at its best.
