Zusammenfassung:	A building air-handling unit (AHU) total cost of operation optimization method includes the steps of providing a mathematical model of the AHU, obtaining weather information and electricity pricing information and labor and material costs for filter replacement, reading the AHU airflow (AF), prefilter pressure drop (PFPD), and final filter pressure drop (FFPD) of the respective Air Handling Unit (AHU), periodically transferring the AF, the PFPD, and the FFPD to an optimization system which is operative to analyze the data in coordination with the mathematical model by assigning at least three selected values in a range surrounding and including the current values of each of the projected prefilter and final filter replacement dates and calculating the efficiency profile of the component of the air-handling system for each of the selected values, then cooperatively optimizing and selecting those values calculated to provide the highest efficiency profile, then periodically resetting the filter replacement dates to those selected by the optimization system.
