CUSM (California University of Science and Medicine)
The site for the new School of Medicine is currently connects directly to the Arrowhead Regional Medical Center campus. It consist of research labs, labs support, clinical anatomy, cadaver labs, etc. Laboratory supply and exhaust systems was designed and placed on standby power to maintain environmental conditions relative to the negative pressure of labs, exhaust form the fume hood and vented base cabinets.
Christian Brothers Mechanical Services was hired during the initial schematic design as a Design Build contractor. In addition to the having Engineers performed the design in-house, this was a BIM coordinated project and a Building Automation Controls system was that performed in-house.
This project was designed to have active pressure control utilizing volumetric offset to maintain negative or positive pressure differential. Other spaces listed above requiring pressurization will have passive pressure control to maintain airflow direction. This was designed to be accomplished through air balance of supply and exhaust systems.
This project is consisted of 6 VRF system totaling up to 200 TONS of cooling with more than 90 indoor fan coils with 2 dedicated outside units with a combined of over 42,000 CFM. Christian Brothers teamed up with ANTEC controls to design a fully operational laboratory control air valves system including 17 pressure controls for both supply and exhaust valves and room pressure controls for the laboratory.
The heating system on this project is comprised of two high-efficiency condensing boilers 3000 MBTU , variable volume, and two circulating pumps.
Due to the complicated system with variety of pressure requirement, we design a fully DDC control system based on web based Niagara N4 BACnet platform. The system controls the exhaust fans, DOAS units, relief fan, and boilers to be integrated with the VRF system.
