BREEZE® is the market-leading air dispersion modeling software used by environmental professionals around the world.

For over two decades, Trinity Consultants has provided air dispersion modeling software for environmental and safety professionals. In 1983, Trinity introduced its first PC-based version of the EPA's mainframe dispersion models, followed in 1987 by the creation of the BREEZE family of products. In 1994, the first Windows versions were introduced, greatly reducing model set-up time for users. Over the years, the BREEZE team continued to enhance functions and features of its products and add new dispersion models to the BREEZE family. Today, over 4,000 professionals in 70 countries worldwide use BREEZE software to assess the impacts of air emissions, fires, and explosions.
BREEZE software is easy to learn and use because it adheres to Microsoft standards for intuitive, uniform graphical user interfaces, and features standardized toolbars, views, menus, commands, and dialog boxes. Our status as a Microsoft Certified Solution Provider (MCSP) ensures that the software products we develop are compatible with new Microsoft operating systems and applications.
Many of the products include an integrated Geographic Information System (GIS), an intuitive data analysis and visualization interface tool, that enables modeled objects and results to interact and be displayed with a variety of geophysical data. The integrated GIS provides users with the most advanced geographic visualization tools available. AutoCAD .dxf files and images in standard file formats (e.g., .bmp, .gif, .tif) can be imported into BREEZE software and used as base maps for easy visualization of affected areas.
