[EnergyPlus_Support] basic error messages

[idoebber <idoebber@xxxxxx>]

I just ran my first IDF file and recieved two warning messages that I was 
wondering if it will effect my results.

The first one is:
   ** Warning ** World Coordinate System selected.  Some Zone Origins are non-
      zero. These will be used in Daylighting:Detailed calculations but not in
      normal geometry inputs.
Will the fact that some of my zone origins are not at the (0,0,0) origin 
effect the simulation.


The second one is:
   ** Warning ** The total number of floors, walls, roofs and internal mass
      surfaces in Zone ROOF ZONE is < 6. This may cause an inaccurate zone 
heat
      balance calculation.
My roof zone is just a standard triangular shape with two roof surfaces 
meeting at an apex.  Therefore this zone only has 5 surfaces.  Will this 
really hurt the heat balance simulation.  If so, should I add a very thin wall 
between the edge where the two roof surfaces meet so that the zone then has 6 
surfaces.

Thanks
Ian
