Salim,
   I assume that you are using Type56; bear in mind that the Type56 
building model is much more complex than a simple u-value multiplied by 
the building area. If you want an idea of the u-value for a particular 
wall, you can look at the wall type manager. The value reported there 
assumes constant inner and outer convection and radiation coefficients. 
You can get the total (static) UA for a zone using NTYPE27. When the 
simulation is running, the inside and outside coefficients are changing 
with time and you should look to the energy gain/loss NTYPEs for 
specific surfaces to get those values.
Best,
  David
