Dynamic facade and roof temperature simulation
For each wall and roof segment in the model, individual materials can be defined. Each wall or roof material can consist out of 3 layers of different materials. To simulate the heat transfer within the wall or roof, a dynamic 7-node model is applied to each segement. For each timestep of the model, the material temperatures are provided at the building outside, the building inside plus 5 points in the center and at the interface of each wall/ roof material.
The energy balance of the outside node continuously considers not only the changes in the meteorological variables, but also the variations in reflected and emitted radiation from other buildings that can be seen from the outside node.
The animation to the right shows the simulated surface temperatures at 14:00 CET for the foreign embassy in Berlin, Germany. The model can be downloaded as an example package here.
