The quality of BIM models is often insufficient for direct mapping into simulation models. Also, the IFC standard still has gaps, particularly in the area of representation of HVAC systems. Enrichment and advanced analysis functions nevertheless make it possible to generate simulation models semi-automatically and reduce effort and errors compared...

The major goal of this study is to demonstrate the feasibility of the dynamic modeling and simulation of both conventional and direct exchange geothermal heat pump applications particularly with regard to performance evaluations. A direct exchange geothermal heat pump system is a geothermal heat pump system in which the refrigerant circulates throu...

This paper presents a framework for the optimal operation of data centers, leveraging their Heating, ventilation, and air conditioning unit, delay-tolerant IT workload and battery storage system for participating in demand response programs. In this context, an MPC-based control framework has been developed that guarantees the reliable operation of...

Exergy analysis is a powerful thermodynamic technique for assessing and optimizing the efficiency of energy systems. In this research, a Modelica®-based tool to perform a fully-dynamic exergy analysis has been developed. Another scope of this study is to develop a component that automatically generates a “Hydraulic network” in the Modelica® modelli...

The ever-increasing installation of renewable electricity generation with volatile feed-in comes hand in hand with the challenge of matching generation and demand at all times, and induces the need for energy storage and more flexible demand. Thereby, the large and predictable thermal demand of the building stock could contribute flexibility if ele...

Information Technology is a dominant player of our modern societies; Data Centres, lying at the heart of the IT landscape, have attracted attention, with their increasing energy consumption being a constant topic of concern, especially when it comes to the negative impact on the quality of their surrounding environment. Nevertheless, recent technol...

This work introduces a multiphysics test bed which supports the testing of renewable energy systems in the context of home energy systems (HESs). The test bed, based on power-hardware-in-the-loop (PHIL) technology, allows for testing renewable energy systems and HESs in a holistic way. Homes, as the melting pot of different forms of energy, are one...
