Twin²Sim

Façade test stand and multifunctional laboratory

The Twin²Sim project consists of a test stand, test rooms and a multifunctional laboratory in a research building.

Twin2Sim: Multifunctional test stand

The project serves the holistic investigation of complex building envelopes and building services engineering within the framework of a multifunctional test stand for façades (short-term investigations of 2-6 months) and a test building, in which the previously characterised façade components can be evaluated in the long term (several years). The test building further serves the evaluation of building services engineering installations in interaction with space and users. After the measurement, simulation and modelling takes place and thus the further development on digital twins is possible. This helps to reduce future development costs by reducing physical prototypes. For only the second time in Austria, the facility allows the measurement of the sound insulation of components in a test stand in timber construction and, for the first time, also the measurement of the longitudinal sound conduction. This function is particularly significant for the development of lightweight (wooden) components, as there are no calculation options for such components and simulation is still exclusively of a research nature.

Simulation on the digital twin

Twin2Sim: Ansicht Südost

With the know-how of the FH Salzburg, components and systems are represented by suitable models using simulations. Further development steps can subsequently be modelled on these digital twins. This procedure does not replace standardised tests, but it saves them having to be carried out several times in the course of development.Twin²Sim is used in funded research projects and in contract research.

High-quality timber construction architecture

The project integrates scientific testing into high-quality timber construction architecture (passive house ready), which will enhance Campus Kuchl both functionally and architecturally. Workplace for additional 20 people is created, which corresponds to an increase of 30% at the site.

Integration into teaching

Integration into teaching and training takes place through the use of the facility as an opportunity for prototype construction with subsequent measurement based evaluation, as a demonstration object for construction, building and control technology and through research-led teaching.

Incubator for the economy

The facility sees itself as an incubator for R&D and business, especially for SMEs without own research facilities, and is available to companies on a non-discriminatory basis, e.g. in the context of cooperative research projects.


Exploded view of test stand construction

Very constant temperature conditions are required in the test stand in order to be able to assess the influence of the test specimens on the room. Therefore, all external surfaces are heated or cooled on two levels and the energy used for this is measured. In addition, temperature, humidity, heat flow, solar radiation, wind and, if required, other physical parameters are recorded in the exterior and interior spaces as well as on the components themselves.

Who is researching at Twin2Sim?

Smart Building
The Team initiated the project, created the basic concept and will use the project for experiments and tests on building envelopes, hydrogen and building technology. The research team will have its workplaces in the project and thus also provide research subjects, e.g. for studies on comfort.

Forest Products Technology & Timber Constructions
The team is responsible for tests on timber construction and airborne sound insulation.

Alpine Building Centre
The Alpine Builidng Centre handles the project funding, has carried out the planning of the scientific facilities and the test fields, and will use the project for experiments and tests on building envelopes and building services technology. The research team will have its workplaces in the project and thus also provide research subjects, e.g. for studies on comfort.
 

The project is funded by the province of Salzburg within the framework of WISS2025.
