Research projects

Das Verbundprojekt „Open T-Shape for Sustainable Development“ hat sich zum Ziel gesetzt, die Entwicklung von fachübergreifenden Handlungskompetenzen zur Erreichung der 17 UN-Nachhaltigkeitssziele (SDGs) zu fördern. Dies geschieht durch die Bereitstellung eines offenen Lernangebotes in Form eines digitalen SDG-Campus. An der Bauhaus-Universität Weimar wird im Rahmen dieses Projektes ein Selbstlernraum zum SDG 11 mit dem Thema Entwurfsprinzipien zum klimasensitiven Bauen konzipiert.

An der Professur Bauphysik der Bauhaus-Universität Weimar wurden in den letzten Jahren zwei verschiedene bildgebende Schlierenverfahren, nämlich das optische Schlierenverfahren mit dem Schlierenspiegel sowie das Background-Oriented Schlieren (BOS) Verfahren aufgebaut und weiterentwickelt, um neuartige Forschungsvorhaben in dem weitläufigen Gebiet der Raumluftströmungen voranzutreiben.

There is a strong connection between particle contamination and health problems in the indoor environment.

The research project "VertiKKA2" is the implementation and continuation phase of the 3-year research project "VertiKKA", in which the concept and the prototype of the VertiKKA, a vertical green water treatment system, were developed.

The primary goal of the project is to develop a measurement system for calculating both room air temperature and flow velocity distribution based on the Acoustic Travel-Time Tomography (ATOM) method.

The Federal Ministry of Education and Research has approved the research project "OLE - Organization of Rural Energy Concepts", in which the Chair of Building Physics is involved together with several partners.

Using the optical schlieren imaging and background-oriented schlieren method, it is possible to visualize indoor airflows non-invasively. In this research project, both methods are investigated and optimized further to be applied in ongoing research related to the topic of building physics.

This project aims to develop an automated, digital monitoring method for the observation and evaluation of the thermal comfort status of existing and new buildings.

"Trail²" - Joint project on energy system transformation in rural areas extended
Under the direction of the Chair of Building Physics, the successful project "Transformation in Rural Areas" (TRAIL) will continue until October 2022. The aim is to optimise the energy supply of small towns and villages with less than 10,000 inhabitants and to reduce energy costs with the help of a data-based online tool.

Sub project: ScanSim

The project team is targeting “smart neighbourhoods” with specialized solutions for planning, energy supply and operation of built-up residential areas.

The research project VertiKKA “Vertikale KlimaKlärAnlage zur Steigerung der Ressourceneffizienz und Lebensqualität in urbanen Räumen” aims to develop an innovative technological approach to increase urban energy, land and resource efficiency, local quality of life, and climate protection.

In this project, the technique of acoustic travel-time tomography (ATOM) will be developed to obtain the non-invasive thermal distribution of a room with an ability of measuring a rapid change in temperature. Subsequently, the ATOM temperatures can be used as the input data for the thermal comfort analysis of an office.

In rural areas and mostly in smaller municipalities under 10,000 inhabitants, there is hardly any overall energy planning.

This research aims to utilise a personalised comfort system (PCS) aiming to efficiently function in heating and/or cooling office spaces to raise comfort levels and provide energy efficient standards for using PCSs in office spaces.

Assessing Airflows Using Schlieren Imaging System to Provide Indoor Air quality and Thermal Comfort

Future city quarter development in the discourse of energy efficiency and resource depletion requires further development of planning methodologies in terms of planning processes and instruments. The energy efficiency potential of large existing building stock will be analysed for building skin retrofit, energy supply systems updates and feasible synergies. By shifting the focus from the single building to the city quarter, the overall CO2 emission reduction of the cluster can be obtained.

Cyclic mechanical stresses in concrete, as in other materials, lead to deformation and damage processes that lead to failure of the component or the test specimen. This failure state is caused even in stress states far below the material strength limit. This characteristic material behavior is collectively referred to as fatigue.

The processes of planning refurbishments and new buildings can be optimized using computer-based methods. The interdisciplinary research-project is located at the interface of engineering sciences and media-informatic at the Bauhaus-Universität Weimar. The project is funded by the federal state of Thuringia and the European Social fund (ESF).

For years, scientists from the Faculty of Civil Engineering and the Faculty of Architecture and Urban Studies have been researching energy-efficient solutions to improve the indoor climate. Starting in 2017, a new method will be used to increase the measurement accuracy of research results in the field of indoor climate control. The Thuringian Ministry of Economics, Science and Digital Society (TMWWDG) supports the research project and provides the necessary financial resources.
