Building Controls for the HVAC System

The main control system for the HVAC in the Intelligent Workplace is by Siemens Apogee Server which was installed in March/April 2011. Previous to this, the system was controlled by Johnsons Metasys Server.

The figure below shows the Siemens control panel located in the basement:

The mullion heating and cooling controls are managed by the Siemens Apogee Server. The main server is connected to 5 sub-systems which controls the highlighted areas in the Intelligent Workplace (IW). The main EN 1 Server Located in mechanical room sends the control signal to the other systems (EN 2, EN 3, EN 4, EN 5) which is received from the Apogee Server. Hence all the main code for the controls is stored in the EN 1 server. Therefore, if the connection is lost between the Apogee Server and the EN 1 system, the system can still function since the main code is stored in the EN 1 server which sends the control information to the other systems.
