Versatile lighting management

Delmatic has supplied a sophisticated lighting management system to Eleven Brindleyplace, contributing to this 14 storey edifice becoming the first building in Birmingham’s Brindleyplace development to achieve a BREEAM Excellent rating. As well as optimising lighting energy consumption, the system provides tenants with a high level of flexibility to customise the lighting to their needs, a key criterion for developers Argent.

Brindleyplace is an award-winning business and leisure centre in the heart of Birmingham. Eleven Brindleyplace comprises of 107,000sq ft of Grade A office accommodation with a ground floor business lounge and serviced meeting rooms and was awarded Construction Project of the Year at the Insider Property Awards 2009.

The Delmatic lighting management system, specified by BAM Design, provides fully flexible addressable dimming control of lighting within office (tenant) areas. It comprises a number of products from the Metro range, including One Ten plug-in modules with DSI dimming, Twelve Twelve and Four Four modules in core areas, routers, sensors and infra-red transmitter fobs – all controlled through the company’s graphical software interface. The lighting circuit is supplied to the office control modules via a busbar and the luminaires plug into the control module.

Crucially, the Delmatic system also provides total flexibility for incoming tenants to personalise and customise the system to suit their individual requirements. The graphical software enables lighting groupings to be configured to suit partitioning and open-plan zoning as well as enabling tenants to adjust lighting levels to suit their individual preferences and use of the space. If required, tenants can also include such features as desktop web browser switching and dimming as well as IP telephony switching and dimming.

To enhance energy efficiency, passive infra-red presence detectors (within inner office areas) relate use of lighting to occupation of areas while multi-sensors (located in perimeter zones) combine presence detection with photocell sensors to relate lighting to both occupation and to daylight levels, dimming perimeter lighting in bright weather.

Lighting within core areas (lift lobbies, toilets and staircases) is controlled by presence detectors which energise lighting when motion is sensed and extinguish lighting after a software adjustable time-out period (set as a default to fifteen minutes). External lighting is controlled on the basis of solar clock and external photoheads.

The system also incorporates a corridor-hold feature such that luminaires configured through software to act as corridor/circulation lighting is secured while associated office areas are in use. The lighting control system within the office areas also integrates with the system in core areas, so that core lighting is secured by occupation of office lighting on any floor.

Each floor is equipped with a router which optimises transmission of data around the network as well as between the lighting control modules and the head-end PC. The router incorporates an LCD panel which enables lighting to be tested, global commands (all on, all off, dimming levels etc) to be broadcast as well as emergency lighting tests to be initiated.

In addition, the system monitors lighting energy consumption within the landlord’s areas by monitoring luminaire hours-run data and multiplying the hours-run data by the lamp wattage. The system integrates with the building’s central battery emergency lighting within reception areas.

The system is managed and monitored through graphical head-end software which displays the active status of lighting as well as providing information on luminaire run times. All changes to system configuration are made through software including the time-out periods of sensors.
