These systems run in the Windows NT operating environment. These automated systems control air handler units, chiller systems, and heating systems. Not only do these system provide accuracy and comfort, but they save on the operating cost of building equipment.
Custom software provides data on the electric consumption of large equipment and also steam usage.
By working closely with the Operating Engineers and outside vendors cost savings strategies are planned and implemented. The Direct Digital Control or DDC controls we now use are more accurate than conventional pneumatic controls and allow the staff to display real time data on temperature and humidity. These set points can be set to alarm within a range and can store the data in memory at the central station for later review. DDC controllers are microprocessor based units that monitor and control a given set of parameters, without any communication from other parts of the system. These DDC points tie back to the main system and can be monitored and adjusted at the graphics central computer in Plant Operations .
