Hello There,
We wanted to simulate several buildings, which all have different heating demands. At first, we changed the conductivity of the materials, to get a higher heat flow towards the outside. Next, we tested the customization of the wall thickness.
In both cases, we got a different annual heat demand, but is there any better approach or is something suggested from energyplus itself?
In Germany there are several building standards like EnEV02 or EnEV16, which defines, how good the isolation of a building is. Therefore, it is necessary to model different annual heat demands.
