    develop a complete integrated building controls system - Intelligent Monitoring and Control System (IMACS), ongoing

With more than 3 million square feet of terminal space and serving more than 33 million passengers a year, the Minneapolis-St. Paul International Airport (MSP), the Metropolitan Airports Commission (MAC) was in need of a solution that would integrate and automate all HVAC, plumbing and lighting systems in the 90+ buildings at the complex with an open protocol and real-time access.

To meet the redesign and upgrade project goals, Harris Controls developed the Intelligent Monitoring and Controls System (IMACS).  The system utilizes the Tridium NiagaraAX framework together with the Java Application Control Engine (JACE) to provides custom sequences for central plants and air-handlers, and with LonMark controllers for application specific VAV box and heat pump sequences.

In using open protocol systems and components, Harris was able to integrate existing sensors, valves, dampers and wiring instead of replacing them, and the MAC was able to competitively bid out all of their automation work including all construction and maintenance of the system.

In under just two years, the MAC exceeded their financial project goals with a return on their investment and continues to work with Harris Controls on an on-going basis for other intelligent building monitoring and control systems projects that conserve energy costs, and improve system performance and occupancy comfort.
