The research project “QuaSi II”, which funded the development of the tools now published under the QuaSi umbrella, has ended at the end of March 2026. Yet this does not mean development is over! We are hard at work finalising the full 1.0 release of ReSiE and have a roadmap for further changes and features.

In addition, a new research project has started, which focuses on the demand side of district energy system simulations. As part of this project new open source tools will be developed and released as part of QuaSi, as well as changes to GenSim to make use of them. More information on this project and the tools will be made available in the near future.

Our simulation tools GenSim and ReSiE are now listed in the wiki of the openmod initiative! Check out the details of GenSim and ReSiE in the wiki.

We are proud to present our new website, which offers news, contacts and other information on the QuaSi project.

The website is intended as a central place to gather all relevant information on the project and its software components, as well as link to other websites with more detailed information, such as the documentation and the repositories hosted on GitHub.
