Vacuum-glazing-window in fully-glazed appearance, opening direction to the outside.
This non-conventional window was concepted during the MOTIVE-project. It's attractive architectural appearance is based on a fully-glazed impression. However, the opening direction to the ouside needs to be furtherly worked on, regarding user acceptance, maintenance, and sun protection.

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).

Superordinate structure of the energy hub
Proposed structure of the interaction between individual building control units and the controller of the energy hub. The controllers used are predictive, optimizing controllers (e.g. model predictive controllers, MPC).

Load shifting potential with EMS
Continuous lines for the first quarter (heating demand) with component activation. With EMS (right), higher outputs are in principle demanded less frequently. Since all power above the maximum power of the heat pump has to be provided by the more expensive district heating, costs can be reduced. The blue area above the heating demand curve represents waste heat from the heat pump, since cooling demand also occurs in the first quarter, which must be provided by the heat pump / chiller.

Simulation: failure of the heating circuit pump
Comparison of a standard control and an EMS that is informed of an impending failure of the heating circuit pump. The EMS preheats accordingly to prevent undercooling. Conversely, however, the comfort limits are sometimes exceeded in the other direction, i.e. a slight overheating, because the time constants are correspondingly long.

Cooling load &Lighting Energy, sorted by total solar transmission
The simulation results of all calculated parameter combinations including active cooling were depicted in a scatter diagram based on their cooling load and lighting energy and sorted by total solar transmission. The percentage shown for the "median area" refers to the total sum of calculated combinations.
