     When the Schulman and Scire building downwash method is used the ISC models require direction specific building heights and projected widths for the downwash calculations.  The ISC models also accept direction specific building dimensions for Huber-Snyder downwash cases.  The user inputs the building height and projected widths of the building tier associated with the greatest height of wake effects for each ten degrees of wind direction.  These building heights and projected widths are the same as are used for GEP stack height calculations.  The user is referred to EPA (1986) for calculating the appropriate building heights and projected widths for each direction.  Figure 1‑2 shows an example of a two tiered building with different tiers controlling the height that is appropriate for use for different wind directions.  For an east or west wind the lower tier defines the appropriate height and width, while for a north or south wind the upper tier defines the appropriate values for height and width.
