Problem description

For the precise Thermal calculations of building and generating of the Thermal model of a building (For more information, see: Calculation of design heat load of rooms), it's very important to verify automatic thermal partitions, created based on structural elements and automatically recognized Rooms, especially in cases of complex geometry (multi-pitched Roof, Dormer).

Solution

1. On 3D view in the H&E(T) (Thermal partitions in heat transmission calculations) scope analyze the completeness of partitions in the thermal model. For the best result turn the visibility of the H&E(T) scope to the The only one visible when active using the right mouse button context menu;

   1. Verifying thermal partitions / H&E(T) visibility.

   
   
2. If fragments are missing, check if the corresponding Rooms are automatic and whether they have closed contours;
3. Check whether a zero-thickness wall has been pasted between the rooms if you expect a thermal partition there;
4. For Roof and Dormer: ensure that the Roof covers the Building contour and is modeled correctly (roof edges, sections, levels). Improve, if necessary, and run the Computation of building structure ;
5. For Building embedded below ground level when using the Ground element, check the boundary between the External wall and Wall near the ground partition types, which is indicated by the ground contour around the Building;
