As Brian mentioned in one of the earlier posts, this may be circumvented by entering the actual meter read dates into eQUEST as shown in the screenshot below. This will align usages shown in eQUEST’s “E*” reports such as ES-E with the actual utility bills. The approach does not allow entering more than one read date per month (e.g. we can’t capture April 3 – 28 bill). For projects where this limitation is an issue we generate hourly reports that show consumption by end use for each meter in the project, and aggregate it into periods that are aligned with utility bills. <o:p></o:p></span></p><p class=MsoListParagraph><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><img width=444 height=330 id="Picture_x0020_1" src="cid:image003.png@01D0ADAB.6D9616B0"></span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoListParagraph><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> <o:p></o:p></span></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><span style='mso-list:Ignore'>4)<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>We then copy simulation outputs (either from ES-E or hourly reports, depending on the method used) into a standard spreadsheet with utility data.
