Thomas Ede is a California Licensed Professional Engineer and Certified Energy Manager with eleven years of mechanical engineering consulting experience in the San Francisco Bay Area. He founded Diablo Mechanical Engineering, Inc. to bring that depth of expertise directly to the general contractors, building managers, and mechanical contractors who need a qualified engineer who understands their world.
Thomas has practiced across the full spectrum of commercial mechanical engineering — from complex central plant design and ground-up construction to fast-moving tenant improvement projects where permit-ready drawings and fast turnarounds matter most. His project experience spans San Francisco, the Peninsula, Silicon Valley, the East Bay, and the North Bay.
His commitment to energy-efficient building design is woven into every project. As a Certified Energy Manager, Thomas approaches mechanical systems not just as infrastructure to be designed, but as an opportunity to reduce energy consumption, lower operating costs, and help building owners meet California's demanding energy standards.
Thomas has served as Engineer of Record on projects of all scales and understands firsthand what it means to deliver a complete, coordinated mechanical package under real-world schedule and budget pressure.
