Hi all, Hope you are very well. I’m modelling a cabin in SketchUp using the TRNSYS3D plugin. In the real cabin structure, several steel posts were used to elevate the cabin and separate its floor from the ground. The air easily flows in this cavity under the cabin, see
Fig. 1. To model the cavity, I’ve considered a bottom zone in which the walls were defined as
Massless Layers with R-value of 0.044 h m^2 K/ kJ (equal to the air gap), see
Fig. 2. However, I’m not sure if this modelling process is correct. Do we have any option in TRNSYS to consider such cavity under buildings? BTW, if this model is correct, how should I calculate the infiltration rate for the cavity section? Any idea is highly appreciated. Thanks a lot for your help.
