North Building Technologies

The Building

Brooke House consists of two blocks, surrounding two courtyards. Each block has three floors totalling 117,000 square feet of office space.

Integrated Controls Philosophy

CJ Design partnership's specification called for the replacement of all controllers in the two roof top plant rooms, along with interfacing to the new Daikin 4 pipe VRF system, interfacing to the Apex lighting system and logging and tracking energy data from the modbus enabled electricity meters.

North zip modules were used to cost-effectively replace the old Trend controllers, with North Integrators providing the control strategy and interfacing to the third party systems.

Overview Schematic

Three Integrators were used, one in each plant room to control the plant and to interface with the Daikin VRF system and one in the basement, which controls the kitchen and conference room AHU's and interfaces with a network of over 100 electricity meters.

The Integrators control the main plant via multiple networks of Zip IO modules mounted in the control panels in each plant room.

The Integrator in the basement also interfaces with the Apex lighting system, this gives live occupancy information to the VRF system and also to the main plant.

Interfaces in the meeting rooms allow users to override local setpoints and lighting levels.

On time, in budget

The system was delivered on time and in budget, engineered by A&M controls and Hurtwood Ltd, supplied by North with Andertechnik as the main contractor all working to a CJ design partnership specification.
