BREEZE Software


In the early 1980s, Trinity Consultants pioneered the development of advanced air dispersion modeling software designed to help environmental professionals perform air quality studies. Today, thousands of environmental professionals in more than 90 countries use BREEZE software to model the dispersion of air emissions as well as fires and explosions. Our commitment to continuous product improvement and expert technical support remains vital to making BREEZE the standard in modeling software. In addition to developing and providing market-leading air dispersion modeling software, BREEZE also offers quality-assured meteorological data for a variety of modeling scenarios.
