[esp-r] Re: insulation and air-tightness

[Achim Geissler]

Hi Arianna,

your description is slightly uninformative. You have a model in which you increase e.g. thickness of insulation? That should be noticeable in the results, what are the areas, changes in thickness, building size etc? You also have an air flow network and decrease e.g. crack dimensions? This, also, should lead to noticeable changes in the results (ach-values). What is the ach before and after the changes? How are leakages distributed across the building envelope?

What is the unexpectedness of your results?

Best
Achim

However, when I update the construction and network files and rerun the simulation I get some unespected results. The insulation and air tightness doesn't seem to make much difference. Do you know why this could be the case?
