Lately I upgraded from OS 2.4.0 to OS 2.5.0 which uses E+ 8.9.0 running a model which went smoothly in OS 2.4.0 I get the following severe warning:

   ** Severe  ** Construction="BASEMENT SOUTH WALL", constructions referenced by surfaces with a
   **   ~~~   ** "Foundation" Outside Boundary Condition must use only regular material objects
   **   ~~~   ** Material="RAINSCREEN AIR GAP- 3CM", is not a regular material object
   **  Fatal  ** GetSurfaceData: Errors discovered, program terminates.

Basement South Wall is as follows:

Any ideas?

Are you asking how to resolve the error, or why you are receiving the error in 8.9.0 when you did not in 8.8.0? If the former, the error message pretty clearly indicates the cause is the Material:AirGap in the construction.

@Eric Ringold Yes I am wondering why I get it in 8.9.0. The work around is obvious. I changed the Air gap into regular construction.
