Ongoing Projects

In this project, the technology of creating scaled models of rooms and taking room acoustic measurements in them, which has been common practice in concert hall planning for a long time, is to be processed to such an extent that it can be used in a simple way and at low cost. All necessary prerequisites are to be created, tested and documented. Thus, this method shall be made available for various R+D applications, for the planning of acoustically demanding music, communication, teaching and working spaces and also for teaching purposes. Components of the project are the creation of test model rooms, the selection and testing of components of the measurement system (sound sources, electronics, microphones, ...), the selection and measurement of sound absorbers for the models, the creation of a special software for model measurements including evaluation, display and all necessary calculations, the testing of the entire system on suitable test objects, the comparison of measurements on the model and on the corresponding model room and a detailed documentation with construction and user instructions.

The project is carried out in cooperation with Dr. Detlef Hennings and is supported by funds of the Förderinitiative Zukunft Bau und der Industrie.

The research project, led by the Chair of Electrical Power Supply Engineering and supported by the Chair of Building Physics and Technical Services, is intended to address a further building block for the energy transition in Germany after the development of smart grids and smart meters. Together with the associated partners Phoenix Contact GmbH & Co. KG, Wuppertaler Stadtwerke GmbH and Bau- und Liegenschaftsbetrieb NRW, the Wuppertal scientists are investigating the load shifting potential of buildings and how this can be optimally harnessed in conjunction with an electricity grid with a high penetration of renewable energy. Essential work lies in the building and system simulation in connection with external signals (grid condition).

The project is supported by the European Regional Development Fund of the European Union in conjunction with funding from the state of North Rhine-Westphalia.

Energy-efficient buildings and an energy supply based on renewable energy are central strategies for the success of the energy transition. simultaneously, the flexibility of buildings with regard to the increasing penetration of wind and PV power and the joint consideration of groups of buildings are coming more into focus.

The VEProB project focuses on the recording, evaluation and optimization of energy flows in interconnected buildings. The demonstration object is the new Wilo Campus in Dortmund, where a "Smart Factory" (40,000 m² GFA) and a modern administration building (12,000 m² GFA) are being built, which are linked via a local heating and cooling network.

The review of the energy balance is a central component of the research project. In addition, analyses and optimizations of the operating and control behavior as well as a comprehensive performance gap analysis of comfort and system parameters are planned. Impulses are expected in particular for the area of qualification of commissioning and building-grid interaction. Beyond the technical-energetic dimension, a construction cost analysis contributes to the verification of planned and actual savings potentials.

The starting point for the joint project with KIT is the problem of ensuring an acceptable summer indoor climate without active cooling and air conditioning in the context of ambitious renovation measures. The overall goal of this project is the development and first demonstration of a combination of acoustic panels with integrated, workplace-related fans to increase user satisfaction. In addition to intensive preliminary tests, the demonstration is to take place in the renovation of an administrative building. There, the building envelope is to be significantly improved in terms of energy and, in addition, a PV system with electricity storage is to ensure that the total energy budget (primary energy weighted) is balanced by the PV system to 80%.

Preliminary investigations show that the requirements for summer thermal insulation cannot be reliably met despite additional measures.

The project is funded by the BMWi through the Forschungsinitiative EnergieWende Bauen durch das BMWi
