Energy savings are expected to give a two year payback for a college campus lighting scheme.
Shooters Hill Post 16 Campus, a south London college, is expecting to achieve complete payback for its lighting management system within two years as a result of energy savings.

The installation uses the LDC lighting management system from Eaton MEM 250 to sense occupancy and adjust artificial lighting levels according to the available natural light.

The system was installed by electrical contractor Robert Ebdon, who recommended an automatic lighting management system after conducting studies that indicated that energy savings would pay for its additional cost in two years. 鈥淲ith conventional switches, classroom lighting is frequently left on when rooms are vacated,鈥� explained Toby Buckley, Ebdon鈥檚 director responsible for the project. 鈥淔urthermore, the main teaching block at Shooters Hill has a south-facing elevation, so it is possible to make full use of the natural light.鈥�

The contractor investigated a number of systems before opting for the Eaton MEM 250 version due to its quick installation 鈥� around 25% of the time for a conventional system 鈥� flexibility and ease of programming.

Flying high

AET鈥檚 Flexible Space System incorporating Hiross underfloor air conditioning has been installed at the redevelopment of TAG Aviation鈥檚 Farnborough airfield. The system was specified for the 拢45 million project by consultant Buro Happold and Reid Architecture in order to overcome the reconfiguration and operational limitations associated with traditional air conditioning systems.

Going underground

Heavy-duty, industrial cable ladder from Mita has enabled railway engineers Jarvis Rail to undertake a 拢150 000 sub-surface cable installation. The project forms part of the infrastructure refurbishment on Liverpool鈥檚 Merseyrail network. Around 1000 m of the ladder supports lv control wiring, fibre optic datacomms network cabling and one metre, single-core power cables.

All aboard the Belfast

HMS Belfast, the warship and floating museum permanently docked on London鈥檚 Thames, has been equipped with a new intelligent fire detection system based on Apollo fire detectors. Firetecnics Systems of London specified and installed the system, which presented a number of challenges including confined working conditions, congested cable routes and the need to lead parties of school children from their sleeping quarters below deck in the event of an emergency. Firetecnics installed over 350 Apollo XP95 analogue addressable devices and a voice evacuation system to fulfil the vessel鈥檚 multiple fire detection requirements as a tourist attraction, conference and educational centre.

Cambridge high society

Marshall-Tufflex has supplied an unusual overhead gantry system to supply gas service units, industrial power sockets, data sockets and equipotential earthing points to laboratories on the Cambridge Science Park. The installation, carried out by Munro 星空传媒 Services, uses 6-m lengths of MT Sterling XL trunking with an aluminium base and pvcu lid. Marshall-Tufflex supplied the system as a single solution, modifying the earthing points and push/click power outlets for inverted use.
