Re: [EnergyPlus_Support] Does the area of the quivslab equal to the building floor?

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

The theory behind the slab program's modeling approach concludes that the 
overriding characteristic is the area to perimeter ratio.  This theory 
concludes that a square of AreaX and a rectangle of AreaY  will produce 
equivalent surface temperature results if the area to perimeter ratio is the 
same.
