AERMOD takes into account the obstruction of wind flow from structures, such as buildings and point sources (i.e., stacks). Like any other model object in BREEZE AERMOD, buildings can be copied and pasted or drawn into the 2D display. Building information can be processed with the embedded U.S. EPA BPIP Prime program.

Building Types

BREEZE AERMOD offers you the ability to create rectangular, circular, and polygon buildings. A simple building mode is an exclusive feature of BREEZE AERMOD that eliminates the error prone requirement of assigning "tier levels" to each and every structure.

BREEZE offers the Downwash Analyst Software as a data analysis tool that takes the cryptic numerical results of AERMOD’s BPIP building pre-processor and displays them in the clearest way possible.
