i've wondered that before. i had a review comment several years ago on
a leed 2.1 project where the reviewer disagreed with the concept that
the overall unmet load hours were fine as i had a spread similar to
yours in the heating or cooling unmet hours. i ended up increasing cmf
and/or capacity until they were more in line with each other. <br>
<br>
i never did receive a better clarification though, and the 90.1 user
manuals only show an example with 0 unmet hours so it is pretty useless
in that regard.<br>
