question #3, see 2001 ASHRAE Fundamantals Handbook, Table 8, chapter 29. They
list small (13-15"), med. (16-18") and large (19-20") computer monitors at 55 W,
70 W and 80 W, respectively while in continuous operation and 0 W while in
energy saver mode. These values are likely for CRTs, not LCDs, which are much
less. Probably best to consult computer manufacturer's data then apply a load
factor for usage. There may also be updated information available from an ASHRAE
RP since 2001.</FONT></SPAN></DIV>

waterside economizers and fan coils, and efficient monitors and
pcs<BR><BR></FONT></DIV>
<P><FONT face=Arial size=2>I've been saving up a few unrelated questions--any
thoughts:</FONT> </P>
<P><FONT face=Arial size=2>1) The default boiler part load curve in DOE 2
drops off substantially at minimum loads. My understanding is that this
is a reasonable reflection of cast iron sectional boiler </FONT></P>
<P><FONT face=Arial size=2>performance. (but not steel fire tube or
condensing) However, I haven't found a source to validate this. Does
anyone have information on real part load performance for code level
efficiency cast iron sectional boilers on the market today? </FONT></P>
<P><FONT face=Arial size=2>2) The ASHRAE 90.1 energy cost budget manual
requires budget baseline four-pipe fan coil systems to have waterside
economizers. The DOE 2.2 software doesn't appear to allow this with the
fan coil system type. Am I missing something in the code, or does anyone
have a work around or approximation?</FONT></P>
<P><FONT face=Arial size=2>3) I've heard various claims for energy savings for
flat screen monitors, and/or sleep-mode locally, or network controlled to
reduced W/s.f. for desktop computers, and more efficient PCs. It seems like
nearly all monitors now have a sleep mode of some sort. Any comments on
the baseline assumption for these features, and how much savings an energy
measure based on these ideas can reasonably produce? </FONT></P>
