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

Dear all,

 

I want to get back the U-value of a building (W/m2.K), is there any way for this purpose ?

 

Best regards
