<DIV><SPAN class=178313318-22082007><FONT face=Arial color=#0000ff size=2>I
would like to discuss question number 1 as well. Appendix G specifies
that Direct Expansion be used as the cooling type for System 6.
However, the PIU system in eQuest does not allow you to use DX coils.
I have seen several archived posts on this same question that say to model a
chiller equivalent to the DX coils, but nothing further. I have
redefined the chiller performance curves accordingly with no success.
Has anyone set up this system succ</FONT></SPAN><SPAN

response to Questions 2 and 3, the U-value and Shading Coefficient of the
glass has significant impact on the energy savings with the HVAC
system. In addition, the visible light transmittance of the glass
directly impacts the Daylighting controls within the rooms affecting
electric usage. The selection of glass should be
investigated when determining the window-wall ratio and the resulting
savings.</FONT></SPAN></DIV>
