DIBS v1.2.0

The DIBS v1.2.0 corresponds to the official Python package and the new DIBS-Repositories (see here for details). The DIBS v1.2.0 includes the following improvements:

1. Dependencies were updated so that the DIBS now works again with the latest versions
2. The variable t_air was rounded at several places to smooth set point based heating/cooling on/off periods.
3. Corrected Bug in writing hourly results of Appliance_gains_demands and Appliance_gains_elt_demands. The calculation of both was and is correct in DIBS, but the values were saved incorrectly, resulting in the last-hour value being written in all hours and summed up to the annual values. Consequently, the Appliance_gains_demand_sum and Appliance_gains_elt_demand_sum were wrong in the Excel outputs. This is fixed now. The Bug did not affect any other output results, as the calculation was and is performing correctly.

DIBS v1.1.0

The release v.1.1.0 includes the following changes:

1. The dataPreprocessingBE.py was verified, and several typo bugs were removed.
2. The lighting demand now considers the occupancy percentage, which leads to more realistic results.
3. New weather data for 109 stations for the period 2007 to 2021 was added. It can now be chosen which weather data period is used.

DIBS v1.0.1

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.

v1.0.0

Initially published version of the DIBS including the preprocessing for the on-site inspection data and interview data of the ENOB:dataNWG project. Outputs are the final energy demand of heating, cooling, lighting, appliances differentiated into electricity and fossil fuels (including to date also renewable solid energy carriers such as wood).
