Conclusion •
A preliminary method for up-scaling building spatial level models onto a continental level by the following steps: (1) Classification of buildings; (2) simulation of the same type of buildings at several locations spread over Europe; (3) simulation of the effect of climate change using artificial local climate data sets; (4) visualization of the results using EU maps.
