Just like in CYPERTHERM LOADS, the full capabilities of IFC Builder have been integrated into the programs with the EnergyPlus™ analysis engine (CYPETHERM EPlus) in version 2025.d.
Now, when a new job is created with the program, there are two options for defining the thermal model: the first one consists of generating the thermal model from the creation of the 3D model of the building in the program itself, and the second one consists of importing the thermal model from the project.
- Creation of the 3D model
When this option is selected, the "3D Model" tab is enabled at the bottom left, leaving the application with the "3D Model" and "Energy simulation" tabs. This new tab, "3D Model", represents the total integration of IFC Builder in the program, and allows the creation of a geometric model with the simplified definition or by construction system of the different building elements, as it incorporates the Open BIM Construction Systems database.
In addition, the analytical geometric model required in the "Energy simulation" tab is generated from this tab. - Importing the thermal model from the project
If this option is selected when creating the job and linking it to the project, the operation of the program is equivalent to that of previous versions, i.e. the thermal model is imported from the project and the user cannot interact with the geometry of the model. In fact, the program does not show the "3D Model" tab and the users can only work on the imported thermal model.
By selecting this option, models from IFC Builder and Open BIM Analytical Model can still be read.
It should be noted that once the desired option for defining the thermal model of the building has been selected, it will not be possible to change this selection when updating the BIM model.
A job must be created with the new option selected to change this.
