The building shape, location, orientation, systems and constructing materials have been modelled in DesignBuilder software, and then it has been simulated for a one year energy simulation. This energy simulation aims to study the energy effect of walls, having a different U-wall value which has been selected to be within the recommended range founded in the "Egyptian code for improving the energy efficiency in commercial buildings". These walls have different properties according to the constructing materials thicknesses. The results show the optimum state that can be selected for the user UR - http://172.23.153.220/th.pdf ER -
