The Energy transition is focused on electricity instead of heat. Their heat energy consumption is 4 times higher than new buildings.

Therefore, a new adjustment of hydraulic balancing including the radiators had been conducted.

Subsequently, rotational speed of pumps and the supply temperature characteristic had been reduced. To understand how such double digit energy savings can arise, wasting of energy as shown in figure 2 must be considered.

The waste is cut back by a better adjustment of facilities. The Figure shows the idealized distribution of 47701-10 waste. Lighter areas show the original state, darker areas show the improvement. The left figure shows the improvement by central optimization of facilities. It is obtained by reducing the maximal possible waste.

In the right figure, the waste is reduced by decentralized optimized user participation. Thus, higher wastes are less often induced. This is in particular the effect which should be gained by HeatMap.

These savings can not be explained with usual effects. With lower inlet temperature the wastes of different facility parts are reduced. The HeatMap project will collect and visualize room temperatures to illustrate the energy consumption for the user.

Furthermore, HeatMap should be established in all universities in Berlin and should be combined to a HeatMap at regional level. Weitere Labore der Beuth Hochschule.
