The UK’s largest ever single public infrastructure development

Crossrail is a new 118km, high-speed rail network for London and the South East and the UK’s largest ever single public infrastructure development.

Delmatic DALI systems are installed throughout central London stations to provide intelligent, secure and energy efficient management and monitoring or normal and emergency lighting.

Project information

We’re providing intelligent, secure and energy efficient networked control and management of lighting within front-of-house, back-of-house and external areas across the seven key central London stations – Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel and Custom House – as well as the network of shafts, portals and depots.

State of the art systems play a key role in minimising energy consumption

The state of the art systems play a key role in minimising energy consumption and supporting Crossrail’s goal to deliver energy-efficient, sustainable solutions for London’s transport network.

The systems enhance sustainability through energy-efficient digital dimming, presence/absence detection, and photocell control in daylit areas, coupled with operational efficiencies gained through real-time management and monitoring of the lighting network. Systems log the number of hours each lamp has been in operation and generate relamping plans which ensure lamps are retired at the optimum point.

A complete DALI solution

We are supplying a complete DALI solution comprising a range of DALI lighting control modules as well as DALI devices including DALI presence detectors, DALI photocells and DALI switches. Delmatic systems use a single network cable for the connection of DALI drivers as well as DALI devices such as switches and sensors,
halving the extent of cabling compared to other systems which require separate buswires for drivers and devices.

Safety critical role for the new Elizabeth Line

The Delmatic networks play a crucial role in station security and safety. The systems integrate with the central battery to provide comprehensive DALI emergency light monitoring and testing as well as tracking the performance of every lamp across the network of stations and highlighting failures in real time.

Delmatic appointed after rigorous selection process

Delmatic were awarded the framework contract with Crossrail Limited based upon a comprehensive prequalification and tender process which reviewed and assessed technical, commercial and project management expertise.

First underground stations in the world with BREEAM ratings

The Crossrail design process included the development of a unique set of BREEAM criteria for underground stations, enabling an objective assessment of Crossrail’s environmental performance as well as creating a benchmark for future projects. All station buildings are rated BREEAM ‘Very Good’ and are the first
underground stations in the world to be rated under the scheme.

Lifetime upgrade guarantee

Delmatic systems are designed and manufactured to last for many years which, in itself, significantly reduces their embodied energy and environmental footprint. Delmatic are the only supplier in the building controls field to offer a lifetime upgrade guarantee which states that any generation of system can be upgraded to latest
technology. This enhances sustainability by reusing a large part of installed equipment, and Delmatic estimate that in the order of 95% of a module is reusable or recyclable.
