Project is an approximately 6,500 sq.ft. full renovation of a historic building within Old Town Alexandria. The building is 3 stories with a basement. Notably, the project included the installation of a monumental open stair, an electrical service upgrade, and lowering of the basement level floor slab to create additional headroom. DesignTech collaborated with Becker Architects and Studio Camus on this historic fit-out.

The new system provides free cooling in economizer mode and the building is equipped with a direct digital control building automation system for ease of operations, maintenance, and service. The third floor executive office is served by a dedicated split system air handling unit with hydronic heat.
