from the output report of SS-R) are 112 and “<b><span style='font-weight:

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Per USGBC the unmet load hours may not be exceed 300 hours (which
is OK in our case) for either the Baseline or Proposed design. And the difference
in unmet load hours between the baseline and proposed design must be no greater
than 50. But in our model difference is greater than 50. So anyone please guide
me that how can I bring down this number?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Currently here is how I am trying to bring down the unmet
load hours in the baseline model. I am increasing maximum heating rate (window shown
below) in these unmet zone (from Zero as default) to a value which is the
maximum heat load for that zone (from SS-R in output file).<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Note: That this is a LEED CS project and system are not
designed. To keep apples to apples I am then going back to the proposed model
and adding the same maximum heating rate to the same zones. Is this the right
approach?<o:p></o:p></span></font></p>
