You are right. The Unmet hours of the proposed design can be less than base case unmet hours and the difference can be more than 50 hours (or upto 300 hours as shown by you). <br><br>However, the ASHRAE 90.1 2004 user manual on page G37states:<br>
<br>"If the number of hours that loads are unmet by either the systems or plant of either the baseline or the proposed model exceeds 300 hours of the 8760 hours simulated, or <b>differs by more than 50 hours between the two models</b>, these simulation results will not be accepted as valid." I think this is incorrect. <br>
<br>According to ASHRAE 90.1 2004 - "unmet load hours for the proposed design <b>shall not exceed</b> the number of unmet load hours for the baseline building design by more than 50." Reverse is not required. <br>
<br>So, the unmet load hours for the proposed design can be less than the number of unmet load hours for the baseline building design by more than 50. <br><br>Vishal<br clear="all">Head, Center for IT in Building Science | IIIT-H | Research University | Gachibowli | Hyderabad 500 032 <br>

<p class="MsoNormal"><font color="navy" size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">If you have a building where the baseline
has 300 unmet hours, and the proposed has 0 unmet hours, no correction is
needed. A correction is only needed if the unmet hours in the <i><span style="font-style: italic;">proposed</span></i> exceeds those in the <i><span style="font-style: italic;">baseline </span></i>by more than 50. (or if
either exceeds 300). Worded differently, if the baseline has 300 unmet

baseline more stringent. </span></font></p>

<p class="MsoNormal"><font color="black" size="3" face="Times New Roman"><span style="font-size: 12pt;">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>
</span></font><tt><font size="2" face="Courier New"><span style="font-size: 10pt;">
PERCENT OF HOURS ANY SYSTEM ZONE OUTSIDE OF THROTTLING RANGE = 4.45</span></font></tt><font size="2" face="Courier New"><span style="font-size: 10pt; font-family: "Courier New";"><br>

follows: If a modeled year has 8,760 hours, can there be 10,000 unmet
load hours? By strict reading of the standard’s definition below, I
would put my foot down stating there can <u>only</u> be 8,760, at most. </span></font></p>

(for what it’s worth, as a young EIT) is this practice developed because
eQuest BDL reports don’t present the crunched numbers in a way that makes
the sum of unmet load hours, as intended by 90.1, easy to determine. I
wouldn’t be shocked to learn other energy modeling software packages generate
LEED compliance summaries featuring unmet load hour totals in sync with the
real intent of ASHRAE 90.1.</span></font></p>

actually a really good question that I was afraid to ask when I first
encountered it – kudos to you! I’ve currently resolved to
follow what others seemed to be doing within and outside of my office:
Sum up all unmet hours for cooling and heating between the zones just as you
describe. In your example, I’d agree that the unmet hours of
your 301 zone building total 301.</span></font></p>

doesn’t seem intuitively to be the intent of the standard, however
between what is suggested within 90.1, the LEED handbook, and the LEED credit
templates – I honestly can’t see any clear indication either way on
which is the appropriate interpretation. </span></font></p>

appropriate metric for ensuring appropriately sized systems should be something
like: “hours of the modeled year in which at least one zone has an unmet
cooling/heating load,” but I think that was avoided by all
concerned parties because it’s too wordy!</span></font></p>

interpretation, again referencing your example, is that all systems of your 301
zone example affecting the zones with unmet cooling/heating hours should have
their heating/cooling/overall sizing capacity ratios increased incrementally
until the design hours fall below 300 (and/or within 50 of the sum from the
other model, depending on your situation).</span></font></p>

<p class="MsoNormal"><font color="black" size="2" face="Courier New"><span style="font-size: 10pt; font-family: "Courier New";">To illustrate my question:
assume you have a building with 301 zones, and each zone has 1 unmet hour
per year. This gives you a total of 301 unmet hours, and requires you to
increase your baseline equipment capacity. But you could argue that, on
average, the building has only 1 unmet hour per year.</span></font></p>
