Have done simulations

[Ewald]

Hello!

I have done some simulations.

I tested what the difference between a light and a heavy construction can be. The light construction had a slightly better U-value, but still, it's not always the U-value that is decisive.

My simulation showed that sometimes a heavy construction with large heat storage capacity can be more advantageous even if the U-value is slightly lower.

Hope the links work.

The U-value of the light construction was 0.318 W/m²K and the U-value of the heavy construction was 0.33 W/m²K.

The energy consumption at each location was 4452 kWh for the respective period and house with the light construction and 4206 kWh with the heavy one.

Typically, however, the U-value is crucial for energy consumption. Heat storage capacity often also plays an important role.
