York High School

York High School was the first school in York County to receive a 100% geothermal heating and air-conditioning system. The building was originally built in 1954 and multiple additions were added to the original structure over the years. In 2006 it received a complete renovation. All of the lights, ceilings, plumbing fixtures and the entire heating and air-conditioning system were replaced. The renovation design centered on enhancing the educational environment but also stressed the energy efficiency of the building. Some of the high performance strategies used were:

  • A geothermal heating and cooling system with 102 geothermal heat pumps and 540 vertical loops (300 ft depth)
  • Individual controls in each classroom which enable the occupant to adjust the room temperature and override the "off" schedule
  • Direct Digital Control (DDC) building automation system
  • T-8 fluorescent lighting in offices, classrooms and hallways
  • T-5 fluorescent lighting in auxiliary gym
  • Occupancy sensors and bi-level light switching were installed in all classrooms
  • Classroom occupancy sensors interface with the building automation system to reset HVAC equipment setpooints when rooms are unoccupied
  • Dedicated fresh air make-up systems
  • Heat wheel equipped energy recovery units
  • Permanent CO2 and humidity monitoring
  • High-efficiency thermal pane windows
