The boilers are located within the roof plant room space.

The central toilet core is provided with a system of mechanical extract ventilation. Twin duty-standby extract fan is provided at roof level. Individual systems of refrigerant air-conditioning comprising in-ceiling concealed ducted-type VRF units provide temperature control throughout the office spaces.
