DIBS_Logo Dynamic ISO Building Simulator (DIBS) is a simulation program for calculating the space heating, occupancy hot water, cooling and electricity demand of German non-residential buildings. Further, the DIBS calculates the heating value based energy uses, the primary energy and the greenhouse gas emission based on the defined factors of the German building energy ordinance (Gebäudeenergiegesetz). The adapted hourly dynamic building energy simulator for single buildings and building stocks is ready to use with ENOB:dataNWG interview and on-site inspection data. The underlying resistance-capacity-model is based on the simplified hourly method of ISO 13790:2008. DIBS is based on the RC_BuildingSimulator and represents an extension of capabilities and adaptation to the requirements of the ENOB:dataNWG project.

DIBS is now available as an official Python package and pip install

Since April 2024 the Dynamic ISO Building Simulator is available as pip install, separated into four individual repositories:

  • DibsCLI: Providing the command line interface for the usage of the DIBS Package. The installation of the DibsCLI module also automatically installs the remaining required DIBS modules listed below.
  • DibsComputingCore: Providing the calculation algorithms (physics model) for the DIBS building simulation.
  • DibsDataSourceCSV: Providing functionality for handling Excel and CSV files, performing calculations on data and returning objects as results.
  • DibsData: Containing the necessary data for simulating buildings in Germany. This includes for example the weather data sets and occupancy schedules.

Current and future DIBS development

Any ongoing and future development of the DIBS will happen in the above-listed four repositories. The 'DIBS---Dynamic-ISO-Building-Simulator' Repository is kept for documentation purposes only.


The following information and documentation, such as the 'Getting Started' section refer to the DIBS implementation still available within THIS repository. However, as the development moved to the above-listed repositories it is advised to check there for the current version of the DIBS.


Getting Started

You can install DIBS via downloading the zip file or either clone this repository.
