10.0pt;font-family:Arial;color:navy'>You may well have tried this, but a first
cut at it would be to check out the SS-R reports for any seriously offending
zones. If there are any, find the LS-B report for each of those zones and see if
any of the components of the maximum load stand out as large contributors and adjust
the specifications of those components, if it seems reasonable to do so. If it’s
any consolation, I am in the throes of the same exercise and it is reminiscent
of trying to hold a fistful of eels – very frustrating. I will be very
interested to see what anyone may have to say about getting a variance on the
300 hours. I’m also very concerned about running into the same (or worse)
situation when trying to get the baseline the match within 50 unmet-load hours
of the proposed building. Thanks for posing these questions.<o:p></o:p></span></font></p>

<p class=MsoNormal style='text-autospace:none'><font size=2 face=Calibri><span
style='font-size:11.0pt'>I would like some guidance concerning methodologies
for systematically meeting unmet hour requirements as indicated in ASHRAE
90.1-2004 Appendix G3.1.2.2. When all building systems are believed to be
correctly entered and unmet hours are out of range. I know I can make
certain changes to this model to obtain less than 300 unmet hours. Is
there any unspoken hierarchy of steps to input changes? Or is it all just
guesswork? Is there anything that is a no-no and should not be
changed? Specifically, I have a project in which the building energy
management system allows cooling when the temperature is above 55°F leading to
several thousand unmet hours for this heating dominated building with unusually
high insulation and solar transmittance values and way oversized existing
equipment. If I making cooling available year round then gone, all
better. Of course there is that graph that shows how cooling in the
winter is over half the cooling in used in summertime. Or should I go
through each zone and systematically change occupancies, equipment
wattages, outside airflows, bogus baseboard heating (anything else I can fit in
here) and then do several hundred iterations of simulations until someday I may
finally have under 300 unmet hours for this … standard. Do I even
need to meet this 300 hours, for LEED purposes I would have to, correct?<o:p></o:p></span></font></p>
