font-family:Arial'>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. <o:p></o:p></span></font></p>

the supply flow for each temperature bin, but I am not sure how to do this
appropriately.<o:p></o:p></span></font></p>
