<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I have a residential (commercial) project
that has large, multi room residential units. Appendix G baseline calls for
packaged terminal heat pump units (PTHP) for this case. However, when I model
these, the supplemental heat energy use gets outrageously high. When I model packaged
heat pump units (residential) the supplemental heat consumption goes to a reasonable
level. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Any idea why the PTHPs would have such an
effect or how I might investigate? Could it be that these units are primarily
designed for one small space? I have reviewed just about all the QC checks I can
think of.<o:p></o:p></span></font></p>
