Conclusion

The presented modeling and simulation laboratory is well

equipped for simulating heat, air and moisture transport

at the scale levels ranging from materials to buildings.

(37)

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;

(38)

Conclusion

Overall we may conclude that this approach is very

promising for simulating the impact of climate change on

the indoor climates of historic buildings at several scale

levels.
