A warning is displayed in my simulation in EnergyPlus :

"GetSurfaceData: Construction DIVIDER WALL of interzone surface SURFACE 3 does not have the same materials in the reverse order as the construction DIVIDER WALL of adjacent surface SURFACE 16 * ~~~ * ...but Nominal U values are similar, diff=[0.0000] ... simulation proceeds. * ~~~ * ...if the two zones are expected to have significantly different temperatures, the proper "reverse" construction should be created ".

What does it mean? How can I solve it?

As it reads I am not sure you must change anything. Anyway if you would like to get reed of the warning you need to make a new construction , let's name it OPPOSITE DIVIDER WALL, and assign the same layers which form DIVIDER WALL just in opposite order. Now assign the the new construction to one of your surfaces 3 or 16 (but not both).

Alternatively, if you create an interior wall construction that is symmetrical (i.e. gypsum, insulation, gypsum), I don't believe you will get this error and you don't need to create the "reverse" construction.
