Davidson County Community College – Transportation Tech Center

Lexington, NC

Project Summary

A new training facility designed for Davidson County Community College.

Project Highlights

  • 100% outside air rooftop unit utilizing an air-to-air energy recovery system
  • Automotive tailpipe exhaust system
  • Split mechanical systems in classrooms


Optima provided mechanical, electrical, plumbing, and fire protection engineering design for a new, 10,000 SF training facility at Davidson County Community College. The building houses an automotive lab, classrooms, and support spaces for the Transportation Technology Center. A 100% outside air rooftop unit, utilizing an air-to-air energy recovery system, was incorporated in the automotive lab to provide comfort conditions while dealing with automotive exhaust requirements. In the lab, the space remains negatively pressurized to prevent vehicle odors from emanating throughout the remainder of the building. An automotive tailpipe exhaust system was also installed to handle both gasoline and diesel vehicle maintenance. Split mechanical systems were utilized in the standard classrooms. The project was completed in 2010. (Images courtesy of Davidson CCC)
