<P class=MsoNormal><FONT size=2 face=Arial><SPAN style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">I am attempting to estimate the cost savings which result from upgrading an air distribution system from constant air volume to variable air volume by the addition of VAV boxes. We have already done a BIN analysis for estimating the savings resulting from the addition of outside air economizers, and I have had some difficulty in figuring out how to modify this analysis to incorporate the VAVs. </SPAN></FONT></DIV>
