<div dir="ltr"><font color="#0000ff">Dear Vishal,</font><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">The Baseline case fan power has to be calculated as per the system type considered in the Baseline Case.</font></div><div><font color="#0000ff">The Baseline Case System type has to be considered from the table G3.1.1A. The system type consideration in the Baseline Case is as per the number of floors, building type, conditioned area and type of heating system in the building.</font></div><div><font color="#0000ff">Now when the Baseline Case system is achieved the Baseline case fan power is considered from the table G3.1.2.9. For system type 1 and 2 the baseline case fan power is taken from the section G3.1.2.9 (0.0003 kW/cfm).</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">The fan power for ventilation and exhaust fans is considered under miscellaneous load. The savings under this category is achieved by having some exceptional calculations.</font></div><div><font color="#0000ff">If the proposed case ventilation or exhaust fan is having two speed to variable flow motors then we can adjust the schedules to have energy savings in the proposed case.</font></div><div><font color="#0000ff">The schedules for ventilation and exhaust fans can be altered depending upon the number of occupied hours and the need of building or space type to have the fans to be operating at lower speeds.</font></div><div><font color="#0000ff">The Baseline case fan is being to have the constant flow based schedules. This has been accepted by USGBC in past for parking fan loads.Hope this might be helpful.To not to have a heck you can use same fan power and schedules in both the cases.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">Thanks,</font></div><div><font color="#0000ff">Sharad.Kumar</font></div><div><font color="#0000ff">Green Horizon Consulting LLP</font></div><div><br></div><div><br></div><div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 3, 2015 at 2:31 AM, <span dir="ltr"><<a href="mailto:equest-users-request@lists.onebuilding.org" target="_blank">equest-users-request@lists.onebuilding.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">Send Equest-users mailing list submissions to<br>
