Our Approach

Southland provided design-build expertise for sheet metal, piping, plumbing, fire protection, and building automation services. This project required a strict and accelerated schedule set forth by BRAC program guidelines, as well as several contract requirements from ASHRAE 90.1, U.S. Green Building Council LEED Silver, and the Energy Policy Act of 2005.

To address the complexity and magnitude of this project, our engineers developed an innovative outdoor air application. We installed a fan-powered induction terminal unit system with a dedicated outdoor air system to produce a high-efficiency cooling system. A sensible chilled water loop was then utilized to provide cooling to the fan-powered induction units and information technology loads, in order to provide humidity, temperature, and ventilation control.

Result

Facing a hard deadline from the client, the design-build team delivered a highly successful, award-winning facility five weeks ahead of schedule.
