Re: [EnergyPlus_Support] Basement program input

["Michael J. Witte" <mjwitte@xxxxxxxx>]

1.  Alongside the walls.  These three fields go together:

Field N3: This specifies the width of the gravel "fill" bed beside the basement 
wall.
Field N4: This specifies the depth of the gravel fill above the floor slab.
Field N5: This specifies the depth of the gravel fill below the floor slab.

2.  There is an "A/P ratio" in the EquivSlab object.  This is the area to 
perimeter ratio of the floor slab only.  I do not know if the 3-D grid 
subdivides the interior space, but this would expect this to have little impact 
on the results.
