the "divide surface" button is only needed if TRNBuild calculates that 
the specific mass flow rate (kg/h.m2) of the floor you are proposing is 
below the allowable limit. If the specific flow rate is below 13 kg/h/m2 
then you have to segment the floor into multiple floors in series (and 
the "divide surface" button will become active.

I am not sure about these but have forwarded the question on to our 
Transsolar colleagues. I will let you know as soon as I hear back from them.
