LIGHTING PROJECTS BRIGHT FUTURE
CP Electronics has installed controls at the newly refurbished Worcester Royal Infirmary building, which now forms part of the University of Worcester. The brief was to provide accurate and easy adjustment of light levels, something vital for today’s places of learning, particularly the lecture areas which have to cater for both traditional teaching and high tech presentations. Flexibility and ease of use are key benefits. The Grade 2 listed infirmary building, now renamed the Charles Hastings building, and the adjacent Mullberry House, which used to house doctors working at the hospital, has undergone a £6m refurbishment to create new facilities for students. It will house the Worcester Business School, along with a new wellbeing centre, teaching spaces and computer suites. Installed and specified by Mitie Engineering Services, various products from CP have been used to control illumination levels in the corridors, lecture areas, corridors and WCs. These include the passive infrared detector EBDSPIR-PRM, which can be set for absence or presence detection, switching the load on or off according to occupancy after a preset time. The time delay is adjustable between 10 seconds and 99 minutes and, if there is sufficient natural light, a built-in photocell will keep the lighting switched off. It also has the benefit of optional manual override and can be used with incandescent, fluorescent and compact fluorescent light sources.
PRINT RUN
Chalmor’s low energy lighting and heating expertise has enabled print specialist Newnorth Print to upgrade lighting and controls at its production centre in Kempston with the help of Resource Efficiency East, Bedfordshire Green Business Network and an interest free Carbon Trust Loan.
A total of 387 light fittings have been upgraded. Newnorth took a long term view and a number of fittings were replaced with new T5 light fittings. Suitable existing fittings were converted using Chalmor’s ReFit T5. In addition, the new lighting is linked to Chalmor’s BlueWave lighting controllers, to ensure that the lighting is only used when needed. The result is a reduced electrical load and an annual energy saving of 183,169kWh. The combination of reduced energy and maintenance costs is providing Newnorth with a total annual saving of 99.8 tonnes of CO2. As Newnorth has adopted the interest free Carbon Trust Loan scheme, the cost of the lighting, controls and installation has been spread over a period of four years. After the loan is repaid, Newnorth will benefit from annual savings of £13,000.
TANKS FOR THE MEMORIES
Megaman has supplied its 7W LED GU10 lamps for use throughout the main public areas of the National Marine Aquarium in Plymouth, Devon. Following installation, the estimated savings are already being calculated as 35,724kWh annually, which amounts to 15.4 tonnes of CO2. The Aquarium had been looking to change its existing halogen lamps situated in all public areas for some time and approached local wholesaler Western Electrical for advice. The original halogen lamps had a very short shelf life and were constantly having to be replaced, plus the heat generation was a problem over some of the smaller chilled water tanks. Having trialled various brands, none came near to the
lux performance of the existing 35W and 50W halogens until Megaman’s 7W LED GU10s were put to the test. Megaman’s GU10s offer a life of up to 25 times longer than their halogen dichroic equivalent, three times less heat output and can be retrofitted into existing fittings, thus providing a fast return on investment.
The Aquarium’s original electrical system included 240V, 12V and track fittings so it was agreed that changing some of the fittings would allow for a uniform GU10 mains powered system throughout. This, in turn, would result in an easier option for the maintenance team to keep one standard lamp type in operation throughout the building.
TRAVEL LIGHT
The high performance Drive fitting from Riegens Lighting has been used with other Riegens luminaires as part of an energy efficiency refit campaign for leading vehicle rental company Hertz UK, based at Heathrow, Middlesex. The brief was to provide a more
energy efficient lighting scheme in the reception areas, Gold Patrons collection point and petrol filling areas as part of a complete building refurbishment/ fit out of Hertz’s £2m investment in its Heathrow operation. Riegens Drive petrol canopy fitting
CLEARED FOR TAKE OFF
A leading UK airport has installed P4’s M-Web self-testing emergency lighting monitoring system as part of a recent £12m development programme. The equipment, which also comprised six data collection boxes covering 276 converted fittings, was installed within the new passenger security screening area and the expanded departure lounge at Liverpool’s John Lennon Airport (LJLA). The airport, one of the 10 busiest in the UK, chose the state-of-the-
art M-Web monitoring system from P4 as the most proven, reliable, cost effective and flexible self-testing computer addressable solution. It was also favoured for its scope in reducing labour costs through its fully automatic self-testing capability, low maintenance and rapid fault identification. The consulting engineers on the project were RPS Gregory, and the equipment was installed by Shepherd Engineering Services. LJLA can use leading emergency lighting self-testing company P4’s
FASTELink software embedded in the M-Web to receive an individual report on the performance of each fitting, and when it last did a self-test and a current status report. The airport has been at the forefront of low cost air travel since the mid- 1990s, when this growth sector of the airline industry started to develop.
offering direct light distribution was used within the Gold Patrons area. Used in conjunction with sophisticated lighting controls, the system automatically switches itself off during daylight hours and dims down when not in use during the night. However, presence detection allows the lights to automatically switch to full power as soon as a customer approaches to collect a vehicle. The Drive fitting, which incorporates 2x55W TCL lamps, was also used to replace the existing HID fittings in the petrol forecourt area, again with absence/presence detection controls. The main reception area was completely refitted and redesigned using Riegens recessed DL- ECO downlights using 2x14W lamps. Riegens Capro recessed 600x600mm luminaires were also installed in public areas of the building, controlled by absence/presence detection sensors.
Riegens has calculated energy savings with the new lighting scheme to be 54 per cent, which equals £6,841 per annum with payback calculated at 16 months.
