<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>This would be really tricky…in
EQUEST, as in DOE-2, one would need to make sure the CWFs are turned on, and
all walls, roofs, etc. are layered. In addition, one would need proper
framing-factors for the walls, and if the building is slab on grade, effective
u-values following Winklemann’s method. One would need to look at the BDL
to ascertain this.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Then comes the fun part…since a
simulation like DOE-2 or EQUEST might not really be simulating what is going
on, one need to have “effective parameters” for the coupling of the
thermal mass to the interior node, etc. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>For example, see the paper by Janet Manke
and Doug Hittle in the 1985 ASME Conference proceedings that used “effective”
parameters to best represent the thermal mass, convection and radiation
exchange within a building. There are other papers that have addressed this
issue using TRNSYS by Jim Braun, et al. in the ASHRAE literature. I believe
there was also an ASHRAE Research Project on this as well.<o:p></o:p></span></font></p>
