I have part load (25%, 50%, 75%, 100%) as the independent variables (X), and part load EIRs as the dependent variable (Z). The part load EIRs from manufacturer are much better than what I get when I use default EQUEST curve. But when I run the model and compare with same model with default curve, my chiller electrical energy consumption is increased significantly (with the manufacturer data). Has anyone been able to successfully create performance curves, or does anyone know of any documentation that might explain how to properly create these curves? Any help is greatly appreciated.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Regards,<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Behnam<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><div><div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>-- <o:p></o:p></span></p></div><div><p class=MsoNormal><span class=apple-style-span><b><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Behnam Jowkar, MASc</span></b></span><b><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><br></span></b><span class=apple-style-span><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Energy Services Associate</span></span><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span class=apple-style-span><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Fluent Group Consulting Engineers Inc.</span></span><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p></o:p></span></p></div><div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>295A Broadway Avenue, Second Floor<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>P.O.
