<div><font color="#333333"><font><font face="tahoma,sans-serif">The all buildings in one file option treats other buildings as shading objects in E+ and as wind shields & shading in design builder, but does not allow for the use of zone multipliers. </font></font></font></div>
<div><font color="#333333"><font><font face="tahoma,sans-serif"><br></font></font></font></div><div><font color="#333333"><font><font face="tahoma,sans-serif">The individual model option allows for zone multipliers and this means shorter simulation run time.</font></font></font></div>
<div><font color="#333333"><font><font face="tahoma,sans-serif"><br></font></font></font></div><div><font color="#333333"><font><font face="tahoma,sans-serif">So I guess it depends on your use; if you want fast run time, single models are best but if you want to model the geographical features more accurately than multi model would be best. </font></font></font><span style="font-family:tahoma,sans-serif;color:rgb(51,51,51)">If you set the project up in DB, then export to E+ than the other models will be shading objects, for existing buildings this is what I like to do. </span></div>
<div><font color="#333333"><font><font face="tahoma,sans-serif">The logic is that for existing buildings the owners are likely to make changes to individual zones, so use of zone multipliers may not provide useful info.<br>

quirks that you ran across? I have a campus project where I need to simulate several buildings and I am trying to decide whether to try and do them in the same file. Thanks.<u></u><u></u></span></p>
