My father, the foreman, always said, ‘Work smarter, not harder,’ but he constantly did both. The apple didn’t fall far from the tree. AEI inspires me to work smart and hard; it also helps me combine my love for all things mechanical with the fast-paced construction community.”

Every day is an opportunity to work on a fantastic array of projects, everything from processing plants to spacecraft, each bringing its own complexities. I take great pride in listening to our clients and providing unique and relevant engineering solutions to each.

Brett Friedman is a registered professional mechanical engineer and principal within AEI’s Engineering Prime division. He focuses on complex HVAC systems analysis and infrastructure design for the industrial, aerospace, test systems, and process markets.

Brett joined AEI Seattle in 2010, working on healthcare and research laboratory projects. When engine test-cell-project opportunities combined HVAC consulting with his passion for engines and vehicles, he relocated to AEI’s Madison office, joining the firm’s Industrial group and supporting projects for General Motors, Ford, John Deere, and Caterpillar. Subsequently, Brett expanded his experience to include hydraulic test labs, central utility plants, manufacturing, flammable and combustible fuels and powders, refrigerants, and data center projects. In addition, he has partnered closely with AEI’s Process group on Current Good Manufacturing Practices (CGMP) and pharmaceutical work. Brett is particularly adept at applying project-appropriate heating and cooling solutions based on client needs and goals for energy and economic efficiencies.

In 2018, Brett accepted the role of aerospace market leader, working with such clients as Aerojet Rocketdyne, Sierra Nevada Corporation, and Collins Aerospace. Brett teaches the Fundamentals of HVAC course at UW-Madison and is a Renewable Energy Systems guest lecturer at South Dakota State University.
