The lecture theatre air handling unit plants are controlled based upon providing a minimum supply air temperature that is below the dew-point of the chilled beam

Humidity control for the lecture theatre are based upon the extract air humidity and the supply air controlled to ensure that there is a maximum humidity of 55%rh.

The lecture theatre cooling is provided by a combination of a chilled beam which provides first stage cooling with the AHU cooling coil providing 2nd stage cooling if required. Various fan coil units are connected to the building management system via the communications network and are controlled on the basis of a return air sensor.

A fully networked Trend IQ2 system building management system was supplied and installed complete with a full 963 front end supervisor package including dynamic plant graphics as part   of this impressive Chatham campus facility

The building was officially opened by the Archbishop of Canterbury Dr Rowan Williams in October 2004 after whom the building is named  and is located on the Chatham Maritime   development close to the historic Chatham  Dockyard.

All of the air handling unit plant (including the lecture theatres) are speed controlled by invertors to maintain a primary index air velocity that serves many VAV boxes.

The branch VAV’s are controlled to provide the required air volume to each local VAV box as sensed by an air velocity sensor in the branch index run. Each local VAV box is modulated based on room air quality conditions.

The branch ductwork for each floor is fitted with motorized control dampers on the supply and extracts systems. These dampers modulate to react to the supply requirement of the VAV boxes.
