[TRNSYS-users] building modeling

[jeannieboef]

Usually, zone calculations are done using the enclosed space as zone.  
Sometimes the zone could incorporate more than one level, where the  
inbetween constructions could still be incorporated for thermal mass  
effects and influence radiation and convection exchanges. Zones should  
be defined as thermal blocks, I.e. those enclosed spaces that will  
experience the same air temperature and connected to the same  
mechanical and electrical building systems are often lumped into one  
zone.

The common wall that you are talking about is usually split. The heat  
transfer is calculated though each area of wall to the adjacent space.  
If you used the whole wall, the poor program would have to virtually  
split the wall in any event to see different dTs across the virtually  
split areas, calculate the heat transfer across each and assign heat  
loss or gain the the corrosponding zones. I don't think the software  
does this as standard. far easier for the user to split the wall.
