<p class=MsoNormal>Hi All,<o:p></o:p></p>
<p class=MsoNormal>Our client would like us to produce an eQuest model that<o:p></o:p></p>

style='mso-list:Ignore'>b)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Can be easily adjusted to reflect space occupancies and
lighting loads<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l1 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>c)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Will reflect the actual building energy usage to within
1%<o:p></o:p></p>
<p class=MsoNormal>Do any of you have experience trying to validate models like
this? <o:p></o:p></p>
<p class=MsoNormal>My concern is that models are approximations, and will not
account for small changes in occupancy, outdoor weather, etc. <o:p></o:p></p>
<p class=MsoNormal>I guess my questions are these:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Even if I manage to put in daily occupant and fan
schedules based on actual use, will the model be accurate enough to take me
within 1%?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>We have been asked to remove plug loads (both for
consumption purposes and cooling loads). Will this be too big of an
assumption to get any accuracy out of the model in the future?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>3)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>How do I modify the weather input file?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>4)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Are there any other ideas I’m missing that will
help us validate a model as an absolute measure of actual building energy
consumption?<o:p></o:p></p>
