CALPUFF 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 CALPUFF, buildings can be copied and pasted or drawn into the 2D display. Building information can be processed by the embedded U.S. EPA BPIP program.
BREEZE CALPUFF offers you the ability to create rectangular, circular, and polygon buildings. A simple building mode is an exclusive feature of BREEZE that eliminates the error prone requirement of assigning "tier levels" to each and every structure.
