  • A.K Suter Elementary school
    Engineering Tomorrow solves complex energy and comfort problems for elementary school

    Built in 1921, A.K. Suter Elementary School in Pensacola, Florida — like many older public schools in the state — used a retrofitted patchwork of packaged and split system air conditioning equipment to keep students comfortable in a warm, humid climate. In order to rejuvenate the almost 100-year-old school, the District decided in 2011 to tear down the old school and rebuild it from scratch using new, high-efficiency HVAC technology. Today, the brand new A.K. Suter Elementary is by far the most energy-efficient of all ECSD schools – thanks in part to advanced HVAC technology, including Danfoss Turbocor® oil-free centrifugal compressors and AB-QM™ valves.

    The path and potential of part-load efficiency

    Inside a building, heat is generated by people, processes, equipment, and lighting - factors that constitute the internal load. Outside, the climate and thermal performance of the building’s exterior - including the amount of insulation, number of windows, and whether the building is north or south facing - comprise the external load.
