Warning: Zone Not Fully Enclosed, Edge Used More Than Two Times
Dear Community, I hope you are having a wonderful new week. I'm fixing some warning messages in my model. One type of the warnings is this Zone not Fully Enclosed. I used the latest SketchUp OpenStudio Plug-in to build the geometry. To simplify my problem, I've created a similar version of my model, and you can access through this link: https://drive.google.com/file/d/1rttf.... This is a very poorly constructed OpenStudio model so it has a lot of other warnings and errors, but I just want to focus on the geometry warning. The detailed warning message is:
* Warning * CalculateZoneVolume: The Zone="THERMAL ZONE 4" is not fully enclosed. To be fully enclosed, each edge of a surface must also be an edge on one other surface. * ~~~ * The zone volume was calculated using the floor area times ceiling height method where the floor and ceiling are the same except for the z-coordinates. * ~~~ * The surface "SURFACE 14" has an edge that was used 4 times: it is an edge on three or more surfaces: * ~~~ * It was found on the following Surfaces: 'SURFACE 18' 'SURFACE 10' 'SURFACE 12' * ~~~ * Vertex start { 27.5388, 14.6661, 4.8133} * ~~~ * Vertex end { 27.5388, 14.6661, 0.0000} * ~~~ * The surface "SURFACE 15" has an edge that was used 4 times: it is an edge on three or more surfaces: * ~~~ * It was found on the following Surfaces: 'SURFACE 18' 'SURFACE 10' 'SURFACE 11' * ~~~ * Vertex start { 15.1384, 14.6661, 0.0000} * ~~~ * Vertex end { 15.1384, 14.6661, 4.8133} * ~~~ * The surface "SURFACE 18" has an edge that was used 4 times: it is an edge on three or more surfaces: * ~~~ * It was found on the following Surfaces: 'SURFACE 16' 'SURFACE 10' 'SURFACE 9' * ~~~ * Vertex start { 27.5388, 14.6661, 4.8133} * ~~~ * Vertex end { 15.1384, 14.6661, 4.8133} * ~~~ * The surface "SURFACE 18" has an edge that was used 4 times: it is an edge on three or more surfaces: * ~~~ * It was found on the following Surfaces: 'SURFACE 13' 'SURFACE 10' 'SURFACE 7' * ~~~ * Vertex start { 15.1384, 14.6661, 0.0000} * ~~~ * Vertex end { 27.5388, 14.6661, 0.0000}
To build the geometry, I simply created spaces in SketchUp, did surface intersection and surface matching. The warning shows that some edges are used multiple times by more than two surfaces, but theses edges are the intersection of several surfaces so it should be used by multiple surfaces from my perspective. I'm wondering if you can provide me some insights on how to fix this problem and what might be the correct way to prevent it in the future. Thank you so much for your help!
