DGS O Street Building

The Department of General Services O Street Building is an 11 story plus penthouse mechanical room, at an 360,000 total gross square feet footprint. This includes office, assembly, storage, building support, parking, and commercial food service space. The building is a Zero Net Energy and is LEED Platinum certified. The building also uses 60% less water than a typical office building of its size.

Airco Mechanical played an instrumental role as a collaborative design-assist trade partner, with Glumac acting as the MEOR. Airco was

involved early and worked with the team to develop energy efficient constructible designs. Specific design features included hydronic piping routed underfloor to serve radiant systems overhead on the level below, heat recovery chiller and a grey water system. Four main air handlers in the penthouse mechanical room serve an underfloor pressurized plenum. Each floor averaged roughly 5,000 linear of copper piping. The general contractor, architect and the entire MEFP BIM team met once a week for 12 months to work on constructability. The building was modeled, and clash detection was run through Navis Works. This process streamlined final design decisions and paved a successful path forward for the construction buildout.
