SS-E in conjunction with the “unmet hours” percentage in the BEMP

when and where your unmet hours are occurring, to help track down what might be
awry to resolve them, if you should desire/need to, as the “important

attention.<o:p></o:p></span></p>

unmet hours, however. Plenty of further discussion as to why in the
archives (search for ‘coincidental unmet hours’). Currently
there’s no perfectly clean way to distinguish coincidental unmet heating
vs. cooling hours, unless you get lucky and have zero of either. I
understand an approach when you have both is to take your total and proportion
it out based on SS-R sums…<o:p></o:p></span></p>

unmet hours are occurring (identifying the zone) and the unmet cooling/heating totals
for each zone is available by clicking “Air Side HVAC” then “Summary”
tabs after a calculation. Highlight any one system in the tree to the
left or click the top of the tree to see them all with sums at the bottom.
Unmet heating/cooling hours are summed for each zone – this happens to be
a fast way to identify where a cryptically-named zone with unmet hours exists in
your model, as well.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal>I can confirm Mike's understanding of the DOE-2/eQUEST
results. To get the correct number of hours of unmet loads, people should
MULTIPLY the Percent hours outside throttling range from BEPS or BEPU by the
total annual "hours fans on" listed in report SS-E.<br>
<br>
One other comment re: Ashu's write-up - I believe that (for DOE-2/eQUEST) a
zone temperature has to be more than one degree outside the throttling range
for that hour to be counted as an hour outside throttling range. So for a
zone with a heating thermostat setpoint of 72 and a 2 degree throttling range
(=> 71-73 degree "throttling range"), the zone temperature would
have to be LESS THAN 70 in order for that hour to be counted.<br>
<br>
related info -<br>
We are contemplating a change to the Air-Side HVAC Summary view in the eQUEST
interface to report this total number of hours as opposed to just the percent
in the totals section at the bottom of the report.<br>
We have also just in the past several days (thanks to the efforts of Steve
Gates) added precision to the percent hours outside throttling range reported
on BEPS & BEPU and ALSO added separate reporting of hours any zone is
either under cooled or under heated, intended for reporting to LEED submission
templates. Assuming no further changes (which is certainly not out of the
question), future releases of DOE-2/eQUEST will report the following in the
BEPS & BEPU reports:<br>
<tt><span style='font-size:10.0pt'>
PERCENT OF HOURS ANY SYSTEM ZONE OUTSIDE OF THROTTLING RANGE = 4.45</span></tt><span
style='font-size:10.0pt;font-family:"Courier New"'><br>
