KNX LIGHTING SYSTEM TRACKS THE SUN FOR PASSPORT OFFICIALS
One of the intelligent lighting systems offered by Electrak Limited, a member of KNX UK, has been utilised within the Government’s new Passport office in Liverpool. It was specified to optimise energy performance and particularly to adjust the level of artificial lighting in the occupied spaces as the sun tracks across the complex, mainly glazed structure.
The new Liverpool Regional Office of the Passport Service is located on Old Hall Street and Faber Maunsell has acted as the Building Services consultant on the project. After the consultant approached Electrak to help develop a design brief for the building, the contract went out to tender and NG Bailey was the successful bidder while the KNX (formerly EIB) equipment has been supplied through Electrak Limited.
As the result of an early and intensive consultation process, the project team decided to install the Electrak KNX lighting power distribution and control system as six separate lines to zone the three floors of the property. In addition to the automatic daylight dimming, the installation features the use of movement sensors in many of the occupied spaces and MT 701 mini panels which implement the programmed lighting control across individual areas.
The property has been designed with sustainability in mind and Faber Maunsell wanted to make the best use of the energy consumed through its designs. They particularly wanted to take account of the building’s curved shape and large glazed area with its high natural light levels.
A lighting control system was therefore required which would respond to the changing conditions. There were also many partitioned areas where movement sensors were applicable.
The KNX installation features a stand alone building management system plus a series of remote lighting control modules. There are also line couplers in the service risers and large quantities of KNX busbar trunking installed within the ceiling.
“I have worked with Electrak’s engineers on a number of schemes in the past and they provide a good proactive service as well as high quality equipment,” says Faber Maunsell’s Senior Engineer on the project, Mr Tony O’Brien.
