@Theo, for those of us who are not familiar with EN 15251 it might be helpful to provide a little bit of background as to what it is (maybe include a link to a website) and how it relates to energy modeling. Can you edit your question to provide more details?
@Theo, I moved your post as an edit to your question since it is not an answer. For future reference, it is most helpful if you post updates to your original question unless you are answering your own question.

Also, the link you posted didn't seem to point to the right page, so I changed it.
