I am assuming from your statement that building is not working in the sense it’s not occupied and no set back is provided. In this case the fans cannot be considered as cycling. But if you want to perform the simulation with the fan power included in the COP then you need to make sure the fan power is made zero in the program, otherwise the fan energy will be double counted(in cooling energy and in fan energy). In case if you want to show the fan power separately in your results then you could go by the method I suggested earlier to segregate the EER and calculate the fan power as indicated in ASHRAE. <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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hope this helps<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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Vignesh.<o:p></o:p></span></p><div><table class=MsoNormalTable border=0 cellpadding=0 width=463 style='width:347.25pt'><thead><tr><td valign=top style='padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal><a href="http://www.iesve.com/"><span style='font-size:8.0pt;font-family:"Arial","sans-serif";border:none windowtext 1.0pt;padding:0cm;text-decoration:none'><img border=0 width=64 height=64 id="_x0000_i1025" src="cid:image001.jpg@01CD94D3.503AE620" alt="Description: Description: IES"></span></a><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'><o:p></o:p></span></p></td><td valign=top style='padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal><b><span style='font-size:13.0pt;font-family:"Arial","sans-serif";color:#006B6E'>Vignesh Kumar</span></b><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'> <br></span><b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#006B6E'>Senior Project Consultant<br>LEED Green Associate.<br>BEE-Energy Auditor.</span></b><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'> <o:p></o:p></span></p></td><td valign=top style='padding:.75pt .75pt .75pt .75pt'><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td style='padding:0cm 0cm 0cm 0cm'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>T:<o:p></o:p></span></p></td><td style='padding:0cm 0cm 0cm 0cm'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>+91-7276239991<o:p></o:p></span></p></td></tr><tr><td style='padding:0cm 0cm 0cm 0cm'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>F:<o:p></o:p></span></p></td><td style='padding:0cm 0cm 0cm 0cm'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>+44 (0) 141 945 8501<o:p></o:p></span></p></td></tr><tr><td colspan=2 style='padding:0cm 0cm 0cm 0cm'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'><a href="http://www.iesve.com/"><span style='color:#006B6E'>http://www.iesve.com</span></a> <o:p></o:p></span></p></td></tr></table></td></tr></thead><tr><td colspan=3 valign=top style='padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>**Design, Simulate + Innovate with the <b><Virtual Environment></b>** <o:p></o:p></span></p></td></tr><tr><td colspan=3 style='padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#006B6E'>IES India Pvt.
