Elevation and eQUEST

1 post / 0 new

Dear Nick, Karen, Javed and Sami: Thank you so much, I will try to confirm your light. Your suggestions make me more sure about my result. I make a summary about the 3 questions: 1. For the 1st situation, I make the 2nd floor higher than before, now it is 1112ft higher than the first floor. The result show no different. So the elevation(in this project situation) didn??t influence the result. I think maybe the software can??t simulate the wind speed changes when the Z-value difference. 2. Now I understand the hole and the default boundary condition tings. Below you said is very clear. 3. The software should make an adjacent judgment of spaces by the internal wall ??next to ??option like below. Thanks again.

Much to read on the topic in the help files if you??re interested, but FYI the default coming out of the wizards is not elevation-sensitive (AIR-CHANGE ?? INF-FLOW/AREA). - To help clarify the first example: Moving spaces away from each other does not break the ??adjacency ties?? that existed (or not) prior. I would not expect any changes of the first example, because you have the flexibility to move the spaces all over the place. If you intend to separate the floors, you should simultaneously re-assign the ??next to?? property or or removing the interior surfaces that joined them to begin with. Note coming out of the wizards, you may not actually find there to be a surface defining that connection, depending on how you defined the shell(s). - I can confirm to my understanding that eQuest does not recognize ??holes?? in any sense. eQuest does recognize the relative XYZ coordinates of exterior surfaces and of building shades when determining solar loads incident on exterior walls, roofs, and windows. You should be able to confirm this by moving the wall in the 2nd example right next to another (and keeping the ??self-shading?? property on for all exterior surfaces). ~Nick NICK CATON, P.E.
