Challenge

A Brisbane blind retailer “Décor Blinds” was contracted to supply the 4450 motorised blinds and Shade Factor was sub contracted to provide the motors and control system inclusive of wiring.

The control system was required to integrate with a BACNet Building Management System (BMS) and drive the blinds to maximise the efficiency of the building.

Solution

LONworks and BACNet interface

LONworks is the ideal companion system for BACNet, which is used to operate air conditioning and air handling.  The solution comprised:

  • Creation of a LONworks backbone running the full height of the building and network on each floor comprising motor control units and motors
  • Sensors, including a sun-tracking sensor and lux sensor (dawn/dusk)
  • Development of a sophisticated automation program with the following characteristics:
    • A sun function that lowers and raises blinds once a brightness level has been exceeded and a delay time has expired
    • A weekend function that increases the delay time, therefore reducing the number of blind movements and saving power usage
    • A light penetration function that adjusts the height of the blinds incrementally so that sunlight always extends to a maximum of 1 metre from the façade
    • An evening function that raises all blinds so that the special lighting effects of the tower can be seen
    • A local control function that allows occupants to override the automatic system until a holding time elapses
    • An “Annual Shading” that analyses the built environment and retracts blinds when they fall into the shadow of adjoining buildings

The control installation was completed on time, within budget and with full compliance to the builder’s specification. A learning phase followed where via remote connection Shade Factor adjusted various parameters to fine tune the installation to the daily life of the building. Each tenant had different requests for local operation and therefore whilst the automatic features were required to be consistent throughout the building the Warema LON system was locally interfaced to operate the blinds via Dynalite, C-Bus, Crestron, AMX as well as wall switches, remote controls, and LON control screens.
