The building itself is served by a condenser water loop which connects to gas fired boilers and dry air coolers for heating and heat rejection. This loop is served by water-cooled heat pumps which are located at the 15th floor. From each heat pump refrigerant is used to serve floor mounted fan coil units within the office areas. Each fan coil unit is provided with its own architectural casing to meet the desired aesthetic of the building.
On the office floors the existing coffer ceiling has been retained with suspended linear luminaire fittings to meet the required illumination levels which works to create an aesthetic with the mechanical services which route around the core. The building is provided with two air handling units, each with heat recovery at roof level which provide the fresh air into the offices along with ventilation columns on the perimeter of the building serving low level grilles.
