2024 40 Under 40: Ali Moussawi, Ph.D., PE, CEM, BEMP, Associate DBIA, 36

Moussawi, a native New Yorker, has been a scientific explorer at heart from early childhood. After defending his doctorate, Moussawi joined the building envelope division of Simpson Gumpertz and Heger, where he contributed to large building projects shaping New York City. He was the lead on several curtainwall forensic investigations, each involving a dispute with high potential remediation costs. Moussawi also developed the basis of design for the envelope at the Delta terminal at LaGuardia Airport and contributed to the design of the renovation at the Air and Space Museum in Washington, D.C. In 2019, he joined the Turner Engineering Group (TEG) at Turner Construction, where he works closely with builders, architects and engineers to provide risk mitigation and cost optimization and to improve sustainability. In late 2020, he started leading the building physics discipline at TEG. He has since led envelope numerical modeling and whole building energy modeling, advising on design risk management and optimization as well as cost of ownership and carbon emissions for more than 50 projects. In January 2024, he earned his building energy modeling professional certification from ASHRAE. Outside of work, Moussawi is a dedicated volunteer who has done dog shelter walks, helped put food together for the vulnerable in the community and helped prepare aid packages for victims of the Turkey/Syria earthquake. Moussawi and his wife do not have children yet, but they do take care of 15 hens in their backyard coop and maintain a garden. They also enjoy hiking, biking and baking homemade pizza.
