equipment is not undersized and does not result in too high unmet load hours.
Undersized equipment consumes less energy along with resulting in large unmet
load hours (depending upon the location). Moreover, if the difference between
the baseline and proposed unmet load hours is high, it can either penalize or
benefit the savings (hence the requirement that the difference shall not exceed
50 hours between the baseline and proposed case).</span></font><o:p></o:p></p>

various building types using a variety of HVAC systems that use Appendix G.
Some are 24/7 facilities and some are schools or offices, etc. Some use zonal
systems and some have an AHU per floor or one AHU for the whole
building. I am not an authority on Appendix G, however, to me
it seems appropriate that the Appendix G requirement is for the whole

300 hours per year is out of the 8,760 hours simulated. If every zone in the
building simultaneously experiences an unmet load (such as when heating is
first turned on after the building is allowed to get very cold), that only
counts as one hour (or maybe two or three for a heat pump). The BEPS and BEPU
DOE 2.2 reports show the percent of hours outside of throttling range. My
understanding is that if this value is 3.4% or less (300/8760) than the
condition is met.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am curious as to how to break up the thermal blocks in
eQUEST. eQUEST allows each zone to be broken down into different space types by
percentage. According to Appendix G, Table G3.1, Section 7, three conditions
have to be met in order to clump thermal blocks together: the space use
classification has to be the same, they have to have exposure to one façade (or
a façade with a <45 deg bend), and they have to be served by the same type
of HVAC equipment. When a large zone is created based on the area being
conditioned by a HVAC system, breaking down the spaces by the percentage
doesn’t meet the three conditions required. If spaces are broken down according
to the ASHRAE requirements, it often leads to a large amount of zones. If all
zones have at least 1 hr. of unmet heating or cooling, and there are greater
then 300 zones, the model will exceed the amount of hours allowed. Any
suggestions on an approach on zoning to simplify the model that meets ASHRAE
requirements?<o:p></o:p></span></font></p>
