1,000,000 sq.ft factory buildings, however we did something that was
roughly equivalent. My company's air handler product normally used a
control loop that monitored differential pressure between the building and the
outdoors, and then controlled the outdoor air amount to maintain a slight
(0.01") positive pressure. Since the controls were very often digital and
we could obtain data from the AHU performance, we knew what the outdoor air
control was doing over the course of a day, or weeks, or
months.</FONT></SPAN></DIV>
