<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Otherwise you could determine how much chilled water is produced and adjust the power of the various chiller plant components to match.

<p>Dear All,<o:p></o:p></p>
<p>"Treatment of District or Campus Thermal Energy in LEED" states that "COP of 4.4 for the total cooling plant average efficiency",<o:p></o:p></p>
<p>but the average efficency includes towers and primary pump equipment.How can I convert the average COP to EIR to use in eQUEST
<o:p></o:p></p>
