Grid Squares
The number of unit squares in the department. This number will be an integer number, equal to the department area divided by the square of the grid size and then rounded to the nearest integer if necessary.
Grid Size
The grid size determines the number of unit squares in a department and the building. The grid size is equal to the length of the side of the unit square. The units are the same as for the building dimensions.
Grid Area
The grid area of a department is equal to its number of unit squares multiplied by the unit square area, which is equal to the square of the grid size. Because of round off effects the discrete grid area of a department might not be exactly equal to its specified area. The grid area must be expressed in units compatible with the building dimensions, i.e., if the building dimensions were given in feet then the grid area must be given in square feet.
