This page presents the main findings of the validation using the data set of 464 non-domestic buildings of the on-site inspection phase of the Project ENOB:dataNWG: Research Database of Germany's Non-Domestic Building Stock (www.datanwg.de). A summary of the DIBS model methodology applied, the validation data set and the validation results are published in the proceedings of the BauSIM 2022 Conference in Weimar (available here). The following validation results act as supplementary information for that publication.

Validation of space heating demand

Validation of heating demand by comparing against measured values. (blue boxes are demand, red boxes measured values)



Scatterplot of space heating demand (x-axis) compared to measured consumption (y-axis) and trendlines for entire simulated non-domestic building population (406 buildings) and for each usage category group.



Statistical analysis of model results for space heating and their performance against measurements for the entire Stock (ALL) and individual usage categories
