Slide 1

...is a brand new open source simulation tool that aims to make building and district simulations accessible to everyone. For this purpose, there are extensive modelling tools and parameterisation checks based on false colours. This means that simulations can not only be parameterised at lightning speed, but also that excellent quality management can always be comprehensively guaranteed. In addition, BIM* data can be easily imported in the future and parameterised into simulation-capable models in no time at all.

Slide 1
Modern solver technology

SIM-VICUS is a modern building simulation platform for the dynamic evaluation of the energy efficiency of a building. It has been specially developed to be able to efficiently calculate particularly complex and large buildings as well as to be able to manage the necessary amount of data. At the same time, the integrated physical models have a high level of detail, which is useful for the dynamic description of the building. In particular, the heavy construction in the European area is taken into account.

Slide 2

With SIM-VICUS all parameters can be displayed and checked dynamically via the 3D interface. This allows the user to maintain an overview within the project and efficiently investigate the correctness of the data. This takes the quality management of data integrity to a new level.

Slide 3
Optimized 3D-Visualization

In SIM-VICUS, the entire paramatrisation is carried out using 3D building data. This means, on the one hand, that the entire building is graphically modelled and created on the basis of 3D interior surfaces and, on the other hand, that parameters are assigned directly to the object (e.g. underfloor heating) and these are also graphically visualised using false colours.

Slide 3
Lightning fast building modeling

SIM-VICUS is currently capable of importing IDF files and IFC* files and developing simulatable models from architectural models at lightning speed.
In addition, rooms, roofs and complex shapes can be created via extensive parameterization dialogs.
This means that three-dimensional simulation models can be created in no time at all and are ready for further use.

News about SIM-VICUS

  • Onboarding Day (in german)
    Building on several years of model and computational core development at the Institute of Building Climatology (e.g. DELPHIN, THERAKLES), a new building energy simulation called SIM-VICUS has been under development since mid-2020. It is a freely available open-source development. The NANDRAD solver, which was also developed at IBK, serves as the computational core for the…
