I was excited about this once but the first pass showed it wouldn’t payoff for my project. If your situation shows promise, you need a detailed model, and if an eQUEST waterside economizer will not give you the series functionality, then I wonder if you could model the modes as separate air cooled chillers in eQUEST with custom curves for each and staging based on outdoor air or seasonal dates. Good luck.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> <o:p></o:p></span></p><div><p class=MsoNormal style='text-autospace:none'><b><span style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:#5F574F'>Paul Riemer, PE, LEED AP BD+C</span></b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> <o:p></o:p></span></p><p class=MsoNormal><b><span style='font-family:"Verdana","sans-serif";color:#C00000'>DUNHAM</span></b><span style='font-size:11.0pt;font-family:"Verdana","sans-serif";color:#C00000'><o:p></o:p></span></p></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Bishop, Bill<br><b>Sent:</b> Wednesday, February 05, 2014 2:33 PM<br><b>To:</b> Sebastian Carrizo;
