Design-Build Effort to Create US Coast Guard Headquarters

This project was the first stage in the Department of Homeland Security’s consolidation efforts. The headquarters is an 11-story building that provides workspaces for over 3,500 employees and includes a separate utility plant and two seven-story parking garages.

Designed to achieve LEED Gold, the campus features 400,000 square feet of green roofs and a variety of stormwater management tools.

The building mechanical plant consists of high-efficiency central chilled water and heating hot water equipment, which includes high-efficiency water-cooled chillers with variable frequency drives, and a variable primary flow chilled water distribution system.

Additional MEP energy efficiency measures for the project include water-side free cooling capability during winter months, demand control ventilation using space carbon dioxide sensors, low power density lighting fixture layouts, and central variable air volume systems with high-efficiency ECM motors at the terminal units.
