Building Science Advisor & Forensic Mechanical Systems Consultant

Dave Borowski

Mechanical Systems • Building Performance • Commissioning • Forensic Diagnostics

For more than five decades, David Borowski has helped solve the mechanical and building performance challenges that most professionals never fully understand. As a nationally recognized Building Science expert and Florida Class A Mechanical Contractor, David combines engineering knowledge, field experience, operational leadership, and forensic diagnostics to identify why buildings fail—and how to restore them to peak performance.

His career spans commercial, industrial, institutional, multifamily, and residential projects, giving him an uncommon perspective on how mechanical systems, building envelopes, ventilation, combustion, humidity, and occupant health interact as one integrated system.
