Group photo Study tour on urban greening and renovation projects in Vienna

The picture shows the participants of the study tour to Vienna, which was carried out as part of the project "Reallabor Gebäude - Gebäude als Reallabor für klimaneutrales, bedarfsgerechtes und leistbares Wohnen".

Axonometry architectural study in the project "Reallabor Gebäude - Gebäude als Reallabor für klimaneutrales, bedarfsgerechtes und leistbares Wohnen"

The illustration shows an excerpt from the architectural study that was carried out as part of the project "Reallabor Gebäude - Gebäude als Reallabor für klimaneutrales, bedarfsgerechtes und leistbares Wohnen". This is a refurbishment project including an extension.

Big picture exploratory project "Gebäude als Reallabor für klimaneutrales, bedarfsgerechtes und leistbares Wohnen"

The illustration shows a big picture of the exploratory project "Gebäude als Reallabor für klimaneutrales, bedarfsgerechtes und leistbares Wohnen". The graphic shows the objectives and planned results of the exploratory project.

Graphic representation of a digital twin

Graphic representation of a digital twin connected to real-time metering data from a building. The digital twin runs in a cloud. With the so-called State Estimator, the simulation model is continuously adapted to the current measurement data from the building.

Time series with forcing terms

Time series of an experiment where the digital twin was adapted to the measurement data using forcing terms. At the beginning of the experiment, the measured and simulated temperatures do not yet match. After that, the differences between the two values ​​are very small. See also other image showing the heat sources and sinks needed for this.

Calculated heat sources and sinks for the digital twin

Time series of an experiment where the digital twin was fitted to the measurement data using forcing terms. The graphic shows the required "Forcing Terms" = heat sources and sinks. See also the other graph with the associated measured and simulated temperatures during the experiment.

Photonic Cooling measurement setup with parabolic reflector

An example of a measurement setup used during the project photonic cooling employing a parabolic reflector. Reflector-Sample-Peltier-module unit in detail (left), complete measurement setup (middle) as well as an overview of the surroundings next to the measurement setup. Image taken on 17.5.2017, Weiz.

Estimated annual peak demand for air conditioning in Vienna for different climate scenarios

Estimated annual peak demand needed for air conditioning in Vienna according to the model calculations applied for the climate scenario RCP4.5 (left) and RCP8.5(right). Data points represent the average annual peak demand, the grey area the uncertainty with a 95% confidence interval and the dashed line the peak demand in Vienna for 2016.

Dissipated power density in dependence of the temperature difference between sample and its surroundings

The figure shows the dissipated power density in dependence of the temperature difference between sample and its surroundings. The highest power density was observed when no design element blocking the radiation of the sample was used. In this case the heat was transferred from the sample to its surroundings by heat conduction, heat radiation and heat convection. Applying a heat radiation blocking element led to a significantly decreased power density as heat was transferred only by heat conduction and heat convection. The intensity of the dissipated heat radiation was evaluated by calculating the difference of the power densities observed for the two different situations (i.e whether the heat radiation blocking element was used or not).
