But looking at the SIM file, this parameter is increasing my zone loads rather than decreasing them, and in fact is causing my space to have more unmet load hours. Should I apply a negative number to this parameter, or is this parameter not the ‘free cooling’ affect. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>That along with the Walkin Box Load under the Air-Side HVAC System Parameter.
