P-915 SOF Mobile Communications Detachment Facility
Mechanical and plumbing design of P-915, Mobile Communications Detachment Facility for Naval Special Warfare Group One. The project is located at the Silver Strand Training Complex – South as part of the Naval Base Coronado, Imperial Beach, CA. The 25,000 SF, one-story building includes offices, training rooms, shower/locker rooms, gear storage, high-bay warehouse space, an outdoor service yard and outdoor training space.
The mechanical systems include a rooftop package air handling unit with 100% economizer with VAV air distribution system, hydronic reheat heating, that attains the following objectives: occupant comfort, indoor air quality, acceptable noise levels, energy efficiency, reliable operation, and ease of maintenance. Heating hot water is generated through a high efficiency modular style propane fired boiler. The HHW distribution system is comprised of boiler mounted circulation pumps to ensure proper boiler operation and secondary variable speed pumps for energy efficiency. Redundant CRAC units are provided for the server-lan room and a high efficiency ductless split system is provided for the electrical room. The entire facility is controlled and optimized through a thorough DDC system. Increased indoor air quality has been provided by increasing the amount of outside air brought in through the rooftop packaged unit.
The plumbing systems include high efficiency water heating systems, complete waste and vent, propane gas distribution, and domestic cold & hot water system serving the building. The plumbing fixtures are provided with low-flow water consuming features.
Sustainable features include high efficiency boilers, variable speed pumps, variable air volume design, and high efficiency cooling units. Energy savings were increased with the addition of an economizer cycle that included gear driven dampers to minimize failures of linkage based on economizer controls. A campus-wide energy management system was also introduced to monitor and reduce use and allow control from the central network.
