Implementation of an automated building model generation tool

Building modeling and simulation are resource intensive tasks, mostly with respect to personnel time and therefore costs, which could benefit from automation. In recent years, there has been an increased interest in automating the task of building modeling, but due to the uniqueness of each building, automated building modeling solutions are very demanding. Consequently, commercial as well as open-source solutions have been made available in the past years, but really reliable solutions are very scarce. This paper presents an approach to automate the generation of thermal building models. A tool has been developed which serves as a base for future studies and improvements in the automatic model creation and calibration field, reducing the modeling effort and resources for thermal building models were reduced significantly. The output of the model generator supports the validation and analysis phase of ISO 50001 regarding forecasting the building performance for validation purposes. While building planners benefit the most from this approach, it will also be the basis to support other modeling approaches automatically which can be used for model-based controls in the field of Building Management.
