The VRV systems have one condenser for Blocks A, B, and C with two (2) off condensers for Blocks D, E, and F coupled to individual ducted hideaway units within the entrance passage ceiling void one in each room via a network of insulated refrigerant copper piping.

Toilets in all the buildings are mechanically ventilated. The bedroom blocks have a central extract fan located in the bulkhead on the second
floor coupled to a network of ducting running along the bulkhead and to the various floors via vertical ducts. Foul air is extracted from each room toilet via ceiling-mounted extract valves Blocks A & B have one fan each while blocks C & D have two fans each and Blocks E & F have three fans each.
Foul air is discharged at the second-floor level to the atmosphere via weather louvres. In the main building, staff toilets extract is via ceiling-mounted Xplair CX10 fans, and these discharge into the ceiling void and to the atmosphere via louvres.
