Initial release of SoDeLe in version 2.0.0

Open source launch of SoDeLe for simple photovoltaics simulation

SoDeLe (loosely translated as “Solar simulation as easy as can be”) is an easy-to-use tool for calculating energy profiles of photovoltaic systems. It is based on the well-validated python-pvlib, but offers a user-friendly GUI based on Microsoft-Excel® (and a CLI with JSON input). SoDeLe can simulate PV systems with parameters from real PV modules and inverters with different orientations. Alternatively, preset standard modules and a constant DC-AC efficiency can be selected. The database of parameters contains more than 35,000 PV modules from various manufacturers. The simulation is based on a weather file, which can be either an EWP file (EnergyPlus® Weather File) or a .dat file from the German Weather Service (DWD).

The latest release can be found here and a short user manual is available within the README of the repository.

Release of new ReSiE version 0.8.0

We have released version 0.8.0 of our energy system simulation engine ReSiE. This release builds on the changes of the previous release v0.7.0, which introduced a lot of new things in regards to how the energy flow and distribution works on busses. With v0.8.0 we finalise these changes and brought the simulation model of ReSiE more closely to a finished state as we envision it. There will be further changes and additional features down the line to address the current modelling challenges when working with district networks.

The latest release can be found here and details are available on the documentation of the QuaSi-Projekt.

Release of new GenSim version 2.15b

We have released version 2.15b of our tool GenSim. This addendum to the latest full release contains various building types as parameter sets ready to be imported. On the basis of this typology new types and custom projects can be modeled more easily than before.

Release of new ReSiE version 0.7.0

We have released version 0.7.0 of our energy system simulation engine ReSiE. This release was developed over some time and contains many internal changes to better support various energy systems and use cases we envision for the future. However we are not done with refactoring and continue to improve our engine to cover a wider range of use cases. Please note that ReSiE in general is still in an early stage and might not be suited for use in projects without consultation on the current capabilities and limitations.

The latest release can be found here and details are available on the documentation of the QuaSi-Projekt.

Release of new GenSim version 2.15

We have released version 2.15 of our tool GenSim that is now fully open source, including a graphical user interface (GUI) based on Microsoft-Excel® (currently available in German only, however the English version will follow soon). GenSim calculates the energy demand for heating, cooling and electric loads of an individual building as yearly high-resolution profiles. The underlying generic building model makes it possible to model any building type. For all necessary parameters, standard data sets for common building types are available directly in the GUI (focus currently on german standards). The Geometry can be defined using a simple generic approach or by importing an own geometry model. An individual building can thus be modelled quickly, which is necessary when modelling entire districts. GenSim uses EnergyPlus® v9 as the simulation engine to perform physics-based thermal building simulation based on the framework that OpenStudio® provides.

The latest release can be found here and a detailed user manual is available within the documentation of the QuaSi-Projekt.
