The aim of the project, which belongs to the funding priority Eneff:Stadt, is to support integrated planning of energy renovation measures concerning the RWTH Aachen’s existing buildings – as a means to ensure that the existing buildings and supply systems will be able to meet future requirements. Building up on the development of technical simulation methods, the aim is to flesh out a sustainable and comprehensive energy and monitoring concept, capturing all relevant energy flows of the building infrastructure. Taking into account the buildings’ energy-supply as well as heating and cooling, based on interconnected generation/supply units, this should lead to a significant reduction in primary energy demand. The project is to be carried out in collaboration with the Institute for Energy Efficient Buildings and Indoor Climate (EBC) and the Department for Facility Management at RWTH Aachen University, as well as with the BLB.
In the project, the properties of the RWTH Aachen are to be modeled in a geographic information system. The buildings’ characteristic parameters are to be used to create simplified models of the buildings for the sake of energy simulation. The heuristically modeled parameters are to be verified by inspections and detailed comparative calculations. In close cooperation with the Institute for Energy Efficient Buildings and Indoor Climate, the model buildings – including the heating and cooling networks – are to be transformed to the modeling language Modelica, using methods developed at RWTH. Another aim is to dynamically simulate and analyze remediation scenarios to improve the energy performance of the building envelopes and the technical installations, as well as conversion scenarios. The results are economic, environmental or primary energy-optimized concepts, as a basis for cost-effective measures to renovate the campus and make the power supply more efficient. The generic concept of analysis can be transferred to other (urban) quarters.
