Tree of project elements in the thermal model
The project element tree describes the structure and organisation of all the elements that make up the thermal model of the building, which will be used in the thermal load analysis and incorporates their geometrical data.
The management of elements of the building thermal model is carried out in the lower tab "Thermal loads", within the upper tab "Thermal model" and, in the "Project" definition area, in the "Project" tree located by default on the left-hand side.
The parameters of the elements arranged in this tree, including the spaces, building elements and linear thermal bridges, can be imported from the information of the different types of elements previously created in the libraries.
Generating the thermal model
The thermal model of the building can be generated in several ways:
- If the building has been drawn directly in the "3D model" tab, by clicking on the "Thermal model" option, the program switches to the "Thermal loads" tab and generates the thermal model of the building in this tab, including the tree of project elements.
- If the building has been drawn in other applications and the model information has been shared to a BIMserver.center project, the program can import it and generate the thermal model in the process of creating a new building or updating the project information.
Tools in "Installation": groups and spaces
The "Installation" group in the top toolbar can be used to manually enter groups and spaces. These elements are added to the project tree under the selected level. Thus, if the "Project" level is selected, the program creates a group or a space at the next level down.
These options are equivalent to the following, which appear in the context menu that appears when right-clicking on a level in the element tree: "Add (Groups)" and "Add (Spaces)".
Groups
The "Group" option allows users to add a group in the project tree. Groups are groupings of spaces or other groups and the only data required is their reference:
- Reference
Group reference.
Spaces
The "Spaces" option allows you to add a space in the project tree, either within a group or under the "Project" level. When adding a space, the program requires the following characteristics to be defined:
- Reference
Space reference. - Area
Floor area of the space. - Volume
Air volume of the space. - Lighting
The value of installed lighting power in each space can be taken from the BIM lighting design model included in the BIMserver.center project.- Installed power (optional)
The value of installed lighting power in each space can be taken from the BIM lighting design model included in the BIMserver.center project.
- Installed power (optional)
- Type
Directly edits of the parameters describing the space. A type already configured in the space libraries can be loaded using the button in the top right corner, which opens the "Import" window, where the desired type can be selected.
Elements
The elements are each of the façades, party walls, partition walls, curtain walls, basement walls, slab-on-ground floors, overhangs, floor slabs between floors and roofs that make up the geometry of a space.
To add elements, the "Add (Elements)" option in the context menu that appears when right-clicking on an ‘Elements’ level, located below the level of any space, can be used.

Openings
The openings that define the program in each space include doors, windows and skylights, both exterior and interior.
To add openings, you can use the "Add (Openings)" option in the context menu that appears when you right-click on an "Openings" level, located below the level of any space.
The data required by the program when entering each of the above-mentioned opening types are as follows:

Tools in the "Edit" group
The following tools in the "Edit" group in the top toolbar of the "Thermal model" tab are used to modify the element tree of the project:
- Add
Adds an item at the selected tree level. - Duplicate
Duplicates the selected item. - Delete

Searches for an item by entering its reference text. - Displace upwards / Displace downwards
Changes the position of the selected item in the tree. - Cut / Copy / Paste
Cuts, copies and pastes elements on the desired lines. - Assign type
This tool is used to assign types from one element to others in the model view. To do this, click on the element the information is to be taken from. The program will highlight the elements assigned to the same type in orange, and the elements assigned to different types in yellow. When clicking on the latter, the type of the first element will be assigned to them.
Selecting elements in the model view
The model view in the "‘Thermal model" tab at the bottom right shows and illuminates the selected tree elements. Furthermore, by clicking on the view itself, users can select the elements in the tree, the type they are assigned to in the library, or the space where they are located.
