-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](https://www.datanwg.de/stichprobenerhebung/breitenerhebung) and [on-site inspection](https://www.datanwg.de/stichprobenerhebung/tiefenerhebung) data. The underlying resistance-capacity-model is based on the simplified hourly method of ISO 13790:2008. DIBS is based on the [RC_BuildingSimulator](https://github.com/architecture-building-systems/RC_BuildingSimulator) and represents an extension of capabilities and adaptation to the requirements of the ENOB:dataNWG project.

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 minimal input data set. The underlying resistance-capacity-model is based on the simplified hourly method of ISO 13790:2008. DIBS is based on the [RC_BuildingSimulator](https://github.com/architecture-building-systems/RC_BuildingSimulator) and represents an extension of capabilities and adaptation to the requirements of the ENOB:dataNWG project.
 
 The Dynamic ISO Building Simulator has been developed in context of the 'ENOB:DataNWG Forschungsdatenbank Nichtwohngebäude' (www.datanwg.de) project and the project 'FlexGeber - Demonstration of flexibility options in the building sector and their integration with the energy system in Germany' at Institut Wohnen und Umwelt (IWU), Darmstadt.

+Welcome to the Dynamic ISO Building Simulator (DIBS) Overview!
+The DIBS project consists of four packages designed to facilitate building simulation tasks:
+1.	**dibs_computing_core**: This package contains the core calculation functionality for the building simulations.
+2.	**dibs_datasource_csv**: It provides utilities to handle CSV input files, which are commonly used as data sources in the default input file type for DIBS building simulations.
+3.	**dibs_data**: This package contains auxiliary data, such as occupancy schedules or weather files, required for the  that aids in building simulation tasks.
+4.	**dibs_cli**: A provides a command-line interface (CLI) tool that which allows users to simulate buildings using the functionality provided by dibs_computing_core.
