Lighting is about 40 per cent of everything we do
I look after all the site utilities, the building management systems, the drainage systems – for my sins – and within all that lot we look after all the energy-efficiency schemes. We’re tasked with reducing energy consumption across the site and meeting certain targets. Lighting probably makes up about 40 per cent of everything we’re doing right now.
We’re well on our way to achieving our carbon reduction targets
Our carbon neutral target is to cut 25 per cent of our direct emissions based on 2005/06 levels by 2015. That’s a reduction of 27,000 tonnes of CO2 a year. We’re well on our way to doing it, we’ve been doing this for about the past three years. From a lighting point of view we’re looking at signficant energy reductions within de ned payback periods.
The lighting has greatly improved the customer experience
We’ve replaced 70W sodium fittings with 28W LEDs at two of our multi-storey car parks. We reduced energy use by 1GWh a year, a 60 per cent reduction. One of the benefits we get out of that – actually it was a side-effect – is the greatly improved customer experience. We’ve moved away from the horrible yellow sodium lights and had a pat on the back for it.
The refit of Terminal 2 is a big success
We’ve just completed a major re t in all the public areas of Terminal 2, which was built about 18 years ago. We replaced all the existing fittings, did our own internal lighting designs and put all LED luminaires up there, achieving annual energy savings of 2.2GWh – more than 50 per cent.
We want the lighting to respond to aircraft by integrating our two control systems
We’re building a control system. We’ve put Dali controls across Terminal 2 for a scheme that we’re working on. We use a flight management system called Chroma, so we know when there is going to be an aircraft at each gate and we know what routes passengers are going to take. The idea is to build a living and breathing control system that knows when people are going to be in areas. Combine it with occupancy and we can squeeze the energy savings as much as we practically can.
It’s about the future
We run 24 hours, and that is a real challenge for us. We’re not a shop that can suddenly turn off when the punters are gone. At this moment in time we have fairly rudimentary controls; it’s how we are going to deal with it in the future. It’s going to be this new intelligent lighting control system that we’re going to put in, it’s going to be flexible for us.
It’s an ever-changing industry
We try to keep on top of new technology. We don’t go gallivanting around the country looking at lots and lots of different technical solutions. We go to the odd trade show; we came to LuxLive and we read the journals. I think we try to keep abreast of the field. It’s ever-changing. There’s been a real increase in the technology in the past couple of years. It’s a bit like computers back in the eighties and nineties, it was: ‘When do we jump on the bandwagon here, because it’s moving so fast?’
We like to be self-sufficient
I’ve got a project engineer and a contract engineer and we do the appraisals in-house. We like to be self-sufficient because it means when we install luminaires or controls and we’ve done it ourselves, we tend to know the systems for future maintenance.
Often, no-one manufactures the luminaire we want
We’re always finding that there are areas that don’t seem to be covered by the main manufacturers. When we did our car parks, we struggled to find a true retro t replacement for a low bay application and we struggled with the flexibility of some of the major manufacturers. We ended up working with local manufacturer MHA Lighting. For those little niche areas where we struggled, we’ve been quite lucky in that we’ve worked quite closely with MHA Lighting and they’ve become a design out t that filled the gap for us.
