Modeling Software for EHS Professionals
About BREEZE Banner

BREEZE, a division of Trinity Consultants, provides the market-leading air dispersion, fire, explosion, and risk assessment modeling software to environmental, hazard and safety professionals in government, industry, consulting, and academia around the world.

Who We Are

In 1983, Trinity Consultants introduced its first PC-based version of the EPA's mainframe dispersion models. In 1987, Trinity followed up this debut with the creation of the BREEZE Software group to coincide with the 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 90 countries worldwide use BREEZE software to assess the impacts of air emissions, fires, and explosions.
