If there are no conditioned spaces and all you have is lighting and some process loads, you should be able to calculate savings in a simple spreadsheet since there are no interacting systems. If USGBC asks you to model it (I really can’t think of a reason why though…), you’d model it as unconditioned in both the baseline and proposed designs, so it wouldn’t matter whether the windows are operable or not. Please keep us posted about how this is resolved. I am curious what LEED policies are for such projects. <o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Maria <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><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Christian Stalberg<br><b>Sent:</b> Friday, November 22, 2013 3:00 PM<br><b>To:</b> equest-users@lists.onebuilding.org<br><b>Subject:</b> Re: [Equest-users] natural ventilation scenario and LEED<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'>Joe,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'>Okay let me elaborate further.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'>This high bay warehouse building has no HVAC whatsoever.
