This adds in IEER values for units so you’re comparing apples to apples. The only projects we have modeled this on have had baseline systems that were 9.5 EER with an IEER of 9.6. With such a small difference between EER and IEER, the 25%, 50% and 75% values aren’t that important. 9.5 EER at full load and 9.6 at the other values will get you the 9.6 required for baseline. For information on how to make curves I would look through the archives of this user group, there have been some great explanations.<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><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#404040'>Bobby Almeida, E.I.T.</span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#4B6C83'> <img width=19 height=21 id="Picture_x0020_8" src="cid:image001.jpg@01CEBF94.B0308D40" alt="Description: LEEDAP_BDCcmyk"> </span><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:#404040'>Project Engineer</span><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'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><img width=62 height=83 id="Picture_x0020_18" src="cid:image002.jpg@01CEBF94.B0308D40" alt="Description: New Image_033010 copy_reduced"></span><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:10.0pt;font-family:"Calibri","sans-serif";color:#404040'>4051 Glencoe Ave. Suite 5 </span><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:10.0pt;font-family:"Calibri","sans-serif";color:#404040'>Marina del Rey, CA 90292</span><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:10.0pt;font-family:"Calibri","sans-serif";color:#404040'>p. 310.591.8172</span><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:10.0pt;font-family:"Calibri","sans-serif";color:#404040'>c. 925.980.2025</span><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'><a href="http://www.gaiadevelopment.com/"><span style='font-size:10.0pt'>www.gaiadevelopment.com</span></a><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:9.0pt;font-family:Webdings;color:#4B6C83'>P </span><span style='font-size:8.5pt;font-family:"Arial","sans-serif";color:#4B6C83'>Please consider the trees before printing this email<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Comic Sans MS";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Comic Sans MS";color:#404040'>Legal Notice: This message and any materials attached are confidential, and are intended solely for the use of the addressee.
