bim2sim
bim2sim is a library to create simulation models for different purposes based on BIM models in the IFC format. The project is based on a base code that provides the possiblity to map the IFC data into a uniform meta strucuture. This structure can then be used to create simulation models for different purposes which is done by plugins. The corresponding project BIM2SIM (see founding section below) adressed the following four domains:
- Building Performance Simulation (BPS)
- Heating, Ventilation, Air Conditioning (HVAC)
- Life Cycle Assessment (LCA)
The focus of the currently released tool is on BPS and HVAC but we already provide basic methods for CFD and LCA as well. The base structure is shown below:

Upcoming Features:
bim2sim is still under heavy development and you can find a lot of features that we want to improve or implement inside the issue section. Anyway here are some of the major ones that we plan to implement:
