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 energy efficiency of the building.
BMS Integrated LONworks control system
LONworks is a widely employed international automation technology for the engineering of complex energy saving strategies in construction and other industries. In this project Shade Factor utilised the market leading components and programming expertise of our German partner Warema to automate 4800 blinds which track the sun and neighbourhood shadows to provide glare free workspaces and reduced heat gain in these premium office spaces.
The physical network consists of a vertical backbone running the full height of the building routed to local networks of motor control units on each floor.
Using a single roof mounted sensor the system mathematically calculates the sun position at any moment in time and together with other logic provides a range of sophisticated functions for occupant comfort:
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 Warema LONworks control screens.
