<TITLE>grab bag--boiler part load, waterside economizers and fan coils, and efficient monitors and pcs</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2 FACE="Arial">I've been saving up a few unrelated questions--any thoughts:</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">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 SIZE=2 FACE="Arial">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 SIZE=2 FACE="Arial">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 SIZE=2 FACE="Arial">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>
