Hi,

I am a student, studying energy efficient building design. I have created a model of a two storey house, using sketchup, I then imported it via DXF into Ecotect, I have created zones for each of the rooms based on this model, (ignoring wall thickness - so every room is the wall thickness bigger?? - I am not sure about this point), The second storey is built on a suspended concrete slab, so this thickness was in my original model, do I need to drop the second storey down this thickness level, or does the adjacent surfaces - used specified value, compensate for this, if you can imagine the model looks like it has a 'gap' between the two floors, and how does the alternate material thickness work? Also I have the steps modeled in the original model but so far I have just created a void from the second floor to the first, is this sufficient? Sorry if the answers are already in the help file, however, perhaps a suggestion would be to have tutorials on modelling different buildings (one, two, multi storey) from scratch (i.e zone by zone,multi-faceted roofs adding steps, etc. etc.), I am willing to upload my models if some one can help.

Kind Regards.
