Efficiency or Sustainability Improvements:
• Certified LEED Gold by the USGBC • 468 geothermal wells, each 250 feet deep are connected to 105 water-based heat pumps in the high efficiency heating and air conditioning system. The closed loop system uses water to transfer heat from the building to Earth in the summer months and from Earth to the building in the winter months, reducing HVAC energy use by 30% • Increased wall and roof insulation. Reflective roof to reduce cooling loads. • High efficiency window glazing • Solar shading provided by canopy on two sides of the building • Sensors adjust artificial light levels in classrooms and corridors based on available daylight and turn lights off when the room is unoccupied. • LED lighting • Xeriscape • Rainwater collection, grey water harvesting from athletics areas and collection of condensate. • Energy Star kitchen equipment • Pulper in cafeteria – students grind up compostable waste into reusable PULP which can be used in composting. This reduces the amount of garbage sent to local landfills by over 50%.
