local authority having jurisdiction. A timer might be one example (off at
night, on during the day). A good place to start is to ask the code
official. Also check the code, such as the IMC 2003 if that is what is
adopted for the project.</SPAN></FONT></DIV>

control<BR></FONT><BR></DIV>
<DIV></DIV><SPAN class=gmail_quote></SPAN>Are parking garage ventilation fans
required to have some kind of control that prevents them from running
continuously (such as CO sensors)? I'm trying to determine whether or not
there's an argument for claiming savings for CO sensors under Appendix G.
My interpretation of section 6.4.3.3.5 in 90.1: "....shall have automatic
controls.....capable of shutting off fans when not required," is that such a
control system is required by code. Also, this seems like standard
practice. Anyone have any insight as to whether this interpretation is
accurate? <BR><BR>Thanks,<BR><SPAN class=sg>Aleka<BR></SPAN><PRE>
