have a typical floor in a high rise that I’m trying to simulate according
to ASHRAE 90.1 Appendix G for LEED EAc1. The floor area is about 1200 m2 or
12916 ft2 the system applied in the design case is Fan Coil units for the
different zones + DOAU for the fresh air. The system applied in the baseline
case is system 7 (VAV with reheat).<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'>My understanding is that the PERIM-CONDUCT
and PERIM-EXPOSED keywords are not yet implemented in the DOE-2.2 engine (used
by eQuest). The U-EFFECTIVE keyword, taken from the DOE-2.1E engine, is no
longer used in DOE-2.2 (but for some reason the program doesn’t complain
when you try to use it – instead it just ignores any input for this
keyword). This doesn’t seem to leave much for us to work with. *Does
anybody know if eQuest does something other than specifying the U-EFFECTIVE
keyword when it asks for a U-eff input for underground surfaces? <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'>The concept for all of these keywords
comes from a paper released by Fred Winkelmann in Building Simulation User News
Vol. 23, No. 6 (<a href="http://gundog.lbl.gov/dirun/23n_d_1.pdf">http://gundog.lbl.gov/dirun/23n_d_1.pdf</a>).
The article suggests creating a fictitious resistance layer in the wall to
create the correct overall U-value for the foundation configuration. Using the
U-EFFECTIVE keyword in addition to specifying this fictitious layer seems
redundant, and you should be able to get the same results without specifying
it.<o:p></o:p></span></font></p>

doing something behind the scenes to calculate this layer.<o:p></o:p></span></font></p>
