Alexandra Hammond is responsible for the environmental impact of Guy’s and St Thomas’ Hospital – and lighting is a significant part of that
Lux met Alexandra Hammond, associate director of sustainability from Essentia, at Guy’s and St Thomas’ NHS Foundation Trust, London. Here’s her view on lighting.
The hospital cares about its impact on the environment and society
I work for Essentia, which is part of Guy’s and St Thomas’ NHS Foundation Trust. I’ve worked for Guy’s and St Thomas’ for the past six years as head of sustainability. That role continues, and we are also able to offer our expertise to other public sector organisations. I look at everything to do with environmental and social impact for the hospital. And lighting is a big part of our energy strategy.
Upgrades are a challenge – but also an opportunity
I would say the biggest challenge we face is upgrading in areas that are quite sensitive, for example patient areas. Also making sure that we don’t get in the way. The exciting thing is that there are lots of opportunities, so if we can improve lighting in patient areas, that can only improve the healing process.
We are investing upwards of a million pounds in lighting at Guy’s and St Thomas'”
Our budget can accommodate change
We have a pretty comprehensive lighting upgrade programme across our two main acute care sites. We are investing upwards of £1 million ($1.5 million) in lighting at those hospitals. What we’ve done is to have an audit on their current lighting, and identified savings opportunities for a like-for-like change. But when we tender for the work – which we’ll be doing shortly – the idea is that we’ll be looking at everything, including biodynamic lighting.
We obviously have to see how we can work within the budget, but the wonderful thing about Guy’s and St Thomas’ is that it’s an organisation that thinks beyond direct paybacks.
Interestingly, the lighting project that we’re doing is part of a big energy-saving project that the trust is undertaking, so it’s about a £12 million ($17.8 million) overall investment in energy efficiency, and lighting comprises about a £1 million of that. What we’ve done is present the business case to the trust with a certain level of guaranteed savings. We’re doing an energy performance contract, so we have a partner that underwrites the savings. If it works within that budget and we get the savings back in, then they’re happy.
We want our patients to have control
I would love to do something creative in our patient areas, particularly on the care wards. We have a lot of patients that are in our wards for a significant amount of time, and lighting can be such an amazing healing factor. Conversely, the wrong lighting can be quite difficult for people, so it’s important that we get it right.
It gets exciting and interesting when you start to see how patients interact with light and how they can control it themselves and improve their stay while in hospital.
Lighting can be such an amazing healing factor for patients on our hospital wards”
LEDs are our default choice now
We do all our own internal maintenance, and we are very strapped for resources. We have an in-house engineering team and they’ve got lots to do. We’re a quite complex, variously aged estate, so the more that we can remove from them maintaining the basics, the better. If we can put in lighting that’s going to stand the test of time, that’s so helpful for us and gives us resources to do other projects.
The guidance we have is: ‘If not LED, justify why not.’ In some areas, we’ve upgraded to T5 so the payback is quite slow. But for the most part, we are moving to LED where we can.
We want our patients to be involved
My proudest moment will be giving our patients the control to make sure that, whether they’re in their own room or whether they’re in a ward, they have the ability to control lighting to give them the best experience possible. And that it actually works, because if the light switch is on and it’s right above the bed and it’s shining right in their eyes, that’s not going to do anyone any good.
The other thing is that we really ought to involve our patients in the process. We want to do some trials and get people to say: ‘I like this, I don’t like this.’ We’ve got the funding, which is the big thing, and we’re tendering for lighting in the next couple of months. My job is to make sure it doesn’t become a like-for-like switch-out, which it could. In some areas it will. That’s the sensible thing to do in some areas, but in others we need to be more creative.
One of the things I really am pleased about is that we’ve introduced photocell-controlled lighting almost across the board. We’ve eliminated the areas where we have lights on and bright sunshine at the same time.
I’d like to see more transparency and standards
One thing that would be really helpful with LEDs is more transparency in the way they’re manufactured and the quality. There’s still an element of having to go to the right supplier, the right manufacturer, the right… and that, I think, adds a premium to the likes of Philips.
But I also think that manufacturers could really help standardise. When we build a new ward, there’s a standard set-up for a hospital bed. It’s the number of plugs around the bed. It’s where the table goes, it’s where the lighting goes to a certain extent. It’s where the patient entertainment system is, and it’s a kind of standard thing, so we don’t recreate it every single time we do a new ward. It would be really good if there were a sort of standard set of principles that we could apply to patient areas. That would help us reduce the design costs, and to just get things done.

Big businesses will soon have to audit their energy consumption and come up with ways they could cut it. Actually doing anything about it, however, is down to them.
Colin Lawson of Lux reports: The Energy Savings Opportunity Scheme (Esos) came into force in July 2014, and requires that all large organisations (defined as those with more than 250 employees) face their energy consumption head-on by conducting regular audits and setting out how they could use less. The scheme presents a significant opportunity for businesses to streamline operations, increase their competitiveness and boost the bottom line – although there is no obligation for them to implement any recommendations from the audits.
We’re now at the halfway point in the rollout of Esos – organisations that registered their eligibility for compliance back in December 2014 are now taking steps to ensure their audits are completed by December of this year. Indeed, the most forward-thinking companies may already have their compliance in the bag.
Decc wants companies to face up to their energy use
Of course, some organisations still view the procedure as an exercise in tick-box compliance. But the conversation has largely moved on from general awareness of Esos legislation to making the most of the opportunities it represents. Compulsory energy audits mean companies have no choice but to acknowledge their energy consumption, and it’s likely that once confronted with stark evidence of the potential savings to be had – UK businesses stand to save up to £1.6 billion ($2.4 billion) – many companies will at the very least want to explore some of the easier energy-efficiency wins.
A survey carried out by the Confederation of British Industry (CBI) reveals that, when asked, ‘How much of a priority is energy efficiency for your business?’ 91 per cent of respondents said ‘high’ or ‘quite high’.
Low-hanging fruit:
Lighting, while not necessarily a big win compared to other energy-saving technologies, represents some of the ripest low-hanging fruit available to organisations wanting to implement Esos recommendations – it’s affordable, quick to implement and offers a strong return-on-investment in the face of rising electricity costs (which have doubled for businesses over the last decade, according to the Carbon Trust).
Indeed, with up to 40 per cent of a building’s electricity use accounted for by lighting, it’s little surprise that official Esos guidance lists some standard lighting measures among its energy-saving suggestions. The mention of measures such as LED lighting, occupancy sensors, daylight sensors, maintenance plans and basic employee engagement suggests that the government still believes the potential of energy-efficient lighting remains under-exploited, and that it sees Esos as a chance to push more companies into implementing these fundamental steps.
“Compulsory energy audits mean companies have no choice but to acknowledge their energy consumption”
As an industry, we have a responsibility to help communicate the many benefits of energy-efficient lighting to our market, not just for complying with Esos, but as a long-term measure of cost-effective sustainability. And of course, taking energy-saving needs into account provides clients with a better value product, which is good news for customer satisfaction levels and business competitiveness. Everyone stands to benefit.
Dispelling myths:
But while for many in the industry swapping outdated lighting for new low-energy offerings is a no-brainer, it’s important to remember just how swiftly technology in this arena has changed in recent years, and to be mindful of some of the lighting myths that continue to linger in the minds of decision makers.
What were once specialist solutions are now mainstream options available to a wider range of organisations at more affordable prices. Customers have greater choice, and will need support in making the right lighting investments for their needs.
Crunching the numbers:
While once the conversation focused on CFLs, LED lighting has come to the fore, saving around 75 per cent energy use while offering the same, if not brighter, light output as halogen lighting. And, according to the Carbon Trust, new LED fittings (as opposed to retrofit LED lamps) have the potential in the UK to reduce electricity bills by more than £300 million and reduce carbon emissions by more than a million tonnes over the next three years.
But, these facts may be unknown to the decision makers responsible for implementing Esos recommendations.
The benefits available to those seeking to address their energy consumption through efficient lighting are ample, matched by the many opportunities the lighting industry has in the face of the Esos legislation. The term ‘low-hanging fruit’ is used a great deal these days, but if Esos regulation indicates anything, it’s that there’s still a sizeable market for these energy-saving measures, and the lighting industry is well positioned to benefit from it just as much as the companies undertaking the audits.
Call us today to discuss your site needs, Tel: 0208-540-8287. We can conduct a lighting survey to assess LED retrofit opportunity, to provide costs and energy (& CO2) savings. We are also able to arrange

Virgin Trains: LED lighting at stations is as much about customer satisfaction as it is about energy
The LED Express: Virgin Trains East Coast will have soon upgraded the platform and concourse lighting at nine stations. As for the trains themselves, watch for new LED lighting in 2018, when a faster fleet from Hitachi (mock-up pictured) starts riding the rails.
‘I can see clearly now the LEDs have come.’ With apologies to song writer Johnny Nash and singer Jimmy Cliff, that is the tune that passengers on Virgin Trains’ new East Coast franchise are starting to sing now that a £1.5 million platform and concourse lighting overhaul is well under way with energy efficient LEDs.
Picking up where the line’s previous owner left off, Virgin is ripping out the old lighting at nine stations that it manages from as far north as Berwick-upon-Tweed on the Scottish border down to Peterborough, and is also upgrading the lighting at its maintenance depot at London’s King Cross station.
The UK government started the job last August when it still owned and operated the Edinburgh-to-London mainline service, then called East Coast. A joint venture of Sir Richard Branson’s Virgin Group and transport firm Stagecoach won the franchise in November, and began operating it at the beginning of March.
The newly branded Virgin Trains East Coast is committing £140 million in upgrades to the line, an amount that should help buoy the £1.5 million lighting project, which is already complete at the Durham and York stations.
Round up the usual benefits, and more
While Virgin expects the lighting to achieve all of the standard LED benefits such as reduced energy and maintenance bills and the elimination of mercury-containing fluorescent lights, it is equally emphasising that the new lighting marks a big improvement in light quality.
Doncaster diodes: A new LED light on the platform one recent morning in Doncaster.
And that translates into big improvements in customer satisfaction and safety, which passengers are alredy reporting in early surveys.
‘It’s really important to stress that whilst new LED lighting comes with obvious environmental benefits in terms of energy costs and the life of the fittings, we’ve also been very keen to stress the customer satisfaction and safety benefits,’ said Tim Hedley-Jones, Virgin Trains East Coast’s major projects director. ‘Replacing lighting is just as important as refurbiishing a facility or putting in a new facility at a station in terms of how a customer feels at that location.’
Tangible intangibles
Noting that customer satisfaction is ‘a bit of an intangible’, Hedley-Jones elaborated on what makes successful night lighting.
‘What we find is that once we’ve done the replacement of the lighting, effectively you’re replicating a daylight scenario at the station,’ he said. ‘That’s been the anecdotal feedback from people – it is a much clearer environment at the station…It’s about how someone feels when they’re at a station. We all know how good we feel generally when the sun shines or when we’re out in the daylight.
‘So I think its about sort of getting into some of the slightly harder to pin down aspects of human behaviour that respond well to high levels of light and to things being bright. We’ve also been doing a painting programme at some of our stations. So when you combine a bit of lighting with improved painting, you really get a feel good factor amongst customers…So customer satisfaction is a really important aspect of doing this project. It’s not just about being a good environmental custodian.’
Safe talk
The safety aspect is easier to pinpoint.
‘We have customers at our stations who perhaps may be carrying lots of luggage, or they may be older people, or people with young children,’ he noted. ‘Quite often they find that stations can be slightly dark, or perhaps the way to go is not clear. What we find is that once we’ve done the replacement of the lighting, again, you’re effectively replicating a daylight scenario at the station. So again there’s a real safety benefit to stop people tripping over or having accidents because they didn’t see something.’
Virgin expects to wrap up all nine stations by the end of the summer. It is close to finishing at Peterborough, Newcastle, Grantham, Doncaster and Newark, and will then move on at Berwick and Darlington. It is not upgrading lighting at a few of its smaller stations, or at Wakefield, a new station that already has modern illumination.
Virgin is refraining from installing high levels of intelligent lighting system in which, for example platform lights would remain off when not needed, and turn on when sensors detect people on the platform, because such systems could confuse train drivers.
‘These are places which are operational bits of the railway, where we have to be very careful about sort of having lights flickering on and off if there are trains coming through and obviously there’s signalling and things like that,’ Hedley-Jones explained. ‘So in this case it’s not necessarily appropriate for there to be that sort of a facility on the concourse or the platforms.’
Sensors would be more appropriate in areas like toilets or back offices, but the 9 station upgrades are focused only on concourses and platforms. Wakefield, the new station, already includes sensors in those areas, Hedley-Jones said.
As for the trains themselves: Watch for improved interior lighting in 2018, when a new fleet of trains from Japan’s Hitachi are due to come into service (the same trains shoud come online on First Great Western service in the south and west in 2017). Those will include LEDs from LPA Excil. If they allow lighting levels to tone down and warm up according to the time of day, then passengers might just find they have something else to sing about.

Something for everyone: Whether your eyes are fresh out of university, or approaching retirement, Philips Connected Lighting allows you to adjust the office lighting to your needs. Photo is from pcruciatti via Shutterstock
LUX reports: Age discrimination aside, a typical office might house workers ranging from their twenties through sixties. And while it’s no secret that the average set of eyes on a young adult typically functions better than those on an older colleague, office and lighting designers have long ignored the difference.
Enough of that, says Philips, which is calling for ‘personalised lighting in your workplace’ to assure that employees of all ages work under the correct, individualised lighting conditions that allow them not only see (what a concept!) but, even better, to produce.
It’s part of the Dutch giant’s efforts to market its ‘Connected Lighting for offices’, which it first introduced a year ago and which it has showcased at The Edge, the environmentally heralded Amsterdam offices of consulting firm Deloitte. The system allows workers to use smartphone apps that adjust overhead lights individually. The lights are connected to an ethernet network, with each light having its own internet address.
‘A 45+ worker tends to need almost double the light needed by a 20 year old for everyday tasks,’ the Dutch lighting gaint says in a press release. ‘The one-light-for-all principle is outdated at a time when we are all living and working longer. Today 30-50 per cent of people in work are over 45 years old…Over the age of 45, people begin to experience a deterioration of their near-sight vision. Research shows, a 60-year-old person needs between two and five times as much light as a 20-year-old to see the same visual detail, let alone to concentrate.’
The wrong lighting could even undermine health and productivity, Philips says.
‘People often call off sick due to headaches and fatigue,’ notes Bianca van der Zande, principle scientist at Philips Lighting. ‘These symptoms may have many underlying causes but perhaps one of these could be the result of prolonged eye-strain due to poor lighting conditions in their working lives. Inadequate lighting can lead to visual discomfort, neck pain, headaches, fatigue and perhaps eventually sick leave.’
A 2013 survey by Philips found that 90 per cent of people who could adjust desk lamps for brightness and colour temperature reported ‘sharper vision, optimum eye comfort, (and) the ability to see smaller details and improved contrast.’ It was a bit of a foregone conclusion, but the idea now is that ethernet-connected, app-controlled overhead lights can deliver the same benefits.
Philips is also calling for government regulations to mandate individualised lighting.
‘Regulatory bodies should take these findings into account for the well-being and productivity of today’s workforce,” says van der Zande.
‘People spend 80-90 per cent of their time indoors from which around 20 per cent is spent at work so the indoor environment determines to a large extent the comfort and wellbeing of the office employee, influencing their performance. It is important that human-centric lighting becomes a part of the regulatory standards, allowing architects and building designers to advise for the best solutions – not only for offices, but for all building environments.’
At long last, harmony across the generations? That would be a story for the ages.

Lux Reports: Retailers are using light as a branding tool. Primark has opted for a bright feel while the opposite approach is popular with retailers such as Hollister and Desigual. Image credit: Primark
Building brands, driving sales, controlling costs, and preserving the all-important ‘look and feel’… who said retail lighting was easy? Here are the eight biggest trends influencing retail lighting in 2015.
1. Energy Saving LED Retrofits:
Retail was one of the first sectors to start dabbling in LED lighting, because of the big energy savings that can be made by replacing electricity-guzzling halogen spotlights. Major retailers are announcing big new rollouts nearly every day: Sainsbury’s, Tesco, Next, Walmart… but it’s still a small minority of stores that have switched to the new technology, and it’s mainly the bigger chains with significant resources and economies of scale behind them. In time, though, it seems inevitable that LED will be everywhere.
OUTLOOK: Loads of shops have already gone LED but there are plenty left – especially the smaller ones.
2. Branding with light:
With stiff competition from online shopping, bricks-and-mortar retailers are having to reinvent their stores as a place where consumers can experience the brands and the product. And they’re learning to use light as one of the most effective ways to become distinctive and recognisable – each in their own way. From Hollister to Primark, light is becoming part of what makes brands what they are.
OUTLOOK: This is a trend the lighting business is well placed to cash in on.
3. New colour technology:
Colour has always been key in retail lighting. Many buyers still assume that going LED means compromising on colour quality; but if you avoid the cheap rubbish, it doesn’t have to be so. Halogen has long been the benchmark for colour quality, but in fact many LED products are now outperforming halogen and the latest colour technologies use specially tuned light to keep whites clean while making certain colours even more vivid
OUTLOOK: LED spent a long time proving its adequacy. Get set for it to start fulfilling its real potential.
4. Lights that do new things:
What if lights could guide you around a shop and send you special offers when you’re looking at particular items? Well, now they can, thanks to super-accurate positioning systems powered by LED lights. It’s done by modulating light in a way the human eye can’t see, but that can be picked up by the cameras in shoppers’ mobile phones. The light from each luminaire carries a unique code, which the phone uses to pinpoint its position. EldoLED is already installing its Lux Award-winning positioning system at retail sites in the US, GE has several trials under way at retail sites in the US and Europe, and Philips is trialling its system at a museum in the Netherlands.
OUTLOOK: We’ve yet to see it in a real-life retail application, but we’re very excited about it.
5. The flight to quality:
We’ve all seen heartbreaking examples of poor-quality LEDs in retail. A well-meaning store manager has tried to save money on energy and maintenance, and now the shop is dim, all the clothes look washed out and the customers feel like zombies. Those days are coming to an end: the wild west of the LED market is being tamed, and even those buyers who had their fingers burned (literally or figuratively) in the early days are trying again, with a renewed focus on look and feel.
OUTLOOK: Some scepticism remains, but LED is winning new friends daily.
6.Overcoming the fear:
Retailers can’t afford to get the look and feel wrong, so LED rollouts tend to be nerve-wracking. There is always a certain risk when you invest in new technology. And with no real standards for LED lighting products, we might just have to embrace that risk. With warranties, funding and improved quality, it’s getting easier, but there’s still inertia – partly the result of bad experiences, uncertainty or mistrust over exaggerated energy-saving and lifetime claims made by manufacturers.
OUTLOOK: Lighting refits are never simple, but more and more people are at it, giving buyers confidence – and it’s getting easier by the day. 7.
Justifying the spend:
It’s easy enough to prove the environmental benefits of an LED upgrade, but sadly that’s not always enough to persuade the finance department to approve the upfront expenses associated with a new lighting scheme. Imagine how much easier it would be if you could prove the correlation between better lighting and increased sales. Unfortunately, it’s not that easy to separate the lighting from the myriad of other variables that influence people’s shopping decisions. As Simon Waldron, Sainsbury’s electrical engineering manager, told Lux: ‘The controllability of variables is missing. We need a standardised approach to proving the link between lighting and sales which at the moment can’t be applied.’
OUTLOOK: Don’t hold your breath for a concrete link between lighting and improved sales… but that won’t stop people looking.
8. Clients are smartening up:
Manufacturers have tried to fight LED specticism with product warranties. But the terms are usually written to protect them just as much as their clients – defining and limiting what they have to do if something goes wrong. In a lot of cases, what a warranty promises doesn’t go very far to resolving a client’s immediate problems. If your lighting installation doesn’t work, it’s not much help to ship them all back to China and wait for new ones. So clients are pushing for their own warranty terms. Like Sainsbury’s, which told manufacturers supplying kit for its ongoing LED rollout what their warranties had to say.
OUTLOOK: As trust and quality improve, and the market becomes accustomed to longer-lasting products, this issue may fade. But for now, manufacturers should expect to be kept on their toes.

Editor in Chief, LEDs Magazine and Illumination in Focus:
Historic railway bridge over the Ohio River now carries pedestrians and cyclists and Louisville has added iconic LED architectural lighting.
Philips Lighting has announced an LED architectural lighting project installed on the historic Big Four Bridge that links Louisville, KY and Jeffersonville, IN across the Ohio River. The dynamic, color-changing solid-state lighting (SSL) is intended to help revitalize the Louisville waterfront and make the pedestrian and bicyclist bridge a destination point in the region.
The Big Four Bridge was originally built in 1895 as a railway bridge and was named based on the four railways served — Cleveland, Cincinnati, Chicago, and St. Louis railways — which were collectively dubbed the Big Four Railroad. The bridge was decommissioned in 1969 and much later renovated by a public-private partnership for pedestrians and cyclist and reopened in 2013.
The project is certainly not the first to use dynamic LED lighting to highlight a railroad heritage in revitalization efforts. For example, the Light Rails project in Birmingham, AL back in the fall of 2013 has drawn tourists and increased safety in Birmingham.
In Louisville, the reincarnation of the bridge had already been a hit with as many as 1 million people visiting annually including both residents and tourists. The architectural lighting was intending to add a nighttime element to what had become a popular draw, with the SSL project able to act as a backdrop for waterfront events. The lighting was included in a six-year plan launched by Mayor Greg Fischer to leverage energy-efficient LED lighting to create a green and inclusive environment around the city.
“This was a strategic opportunity to leverage LED technology to further enhance the city’s most popular attraction and continue the momentum of moving Louisville forward as an innovative and independent city,” said Mayor Fischer. “The new lighting will make the bridge safer at night, enhance waterfront events, and contribute to the artistic flair and pride of this community.”
The project utilized more than 1500 Philips Color Kinetics luminaires on the interior and exterior structure of the bridge. The dynamic software-based control system was installed by Vincent Lighting Systems. The light show is visible from dusk to 12:30 AM nightly from the bridge and surrounding parks.
Philips has been instrumental in supplying the SSL products for many of the most significant outdoor architectural lighting projects around the globe. Philips was the supplier behind the Birmingham and San Francisco projects. Philips also supplied the lighting for the
dynamic lighting of the Miami Tower,
New York’s Madison Square Garden, and many more SSL projects.
“Illuminating iconic structures creates a meaningful impact in a community, a source of pride for residents that brings people together, attracts visitors, and is a reflection of the city,” said Amy Huntington, president of Philips Lighting Americas. “The Big Four Pedestrian Bridge is a shining example of the positive impact that public-private partnerships can have in our communities. We are committed to working with city officials and local organizations to help make neighborhoods more livable.”

Coming to a Woolworths car park near you: the retailer is planning to roll out its LED lighting scheme to other stores following the massive energy savings it achieved in Coorparoo.
LUX reports: Compared to other conventional lighting solutions, T5 is still seen by some as too efficient for the facilities team to justify upgrading to an LED lighting system. But combined with controls, even the leap from T5 fluorescent lighting to LED can yield significant savings.
Woolworths is a case in point; the retailer’s branch in the South Eastern Brisbane suburb of Coorparoo managed to save 77 per cent energy in its car park area with LEDs and occupation sensors, and earned a Peak Load Reduction Reward for its efforts.
One of the reasons the management was looking for a new solution was the amount of hours the light was on in the car park. The T5 fittings, which had an average life span of two years, were on all day and night, with no control system in place.
The entry to the car part was lit with twin 28W T5 fittings which had been retrofitted in 2012.
When most of the T5s predictably started to fail at the same time, James Dwyer of Jones Lang Lasalle (JLL), which has a national building management contract for Shopping Centres Australia’s 77 retail assets, investigated lighting upgrade options. Dwyer was looking for a solution that would last longer than the T5s and save Woolworths the costs of frequent lamp replacements and maintenance.
The JLL team had recently completed a fire stair and car park lighting upgrade at CP1, a commercial office tower in Brisbane, where LEDs were installed. The positive feedback from the building manager there helped convince Shopping Centres Australia, the owners of Woolworths, that LED was the way forward.
Lighting manufacturer Enlighten helped Dwyer complete an unbudgeted capital expense application and detailed return on investment projection, which ‘impressed the owners and ensured that my application was approved,’ Dwyer said.
Dwyer opted for Enlighten’s Chameleon light fitting, which is built for long-lit areas such as fire stairs, car parks and back of house areas.
No more wasted light
Most of the new LED fittings will only be on when needed, thanks to an in-built motion sensor which instantly switches the light from the standby 8W light output to the full 35W output for a set period of time which can vary between 15 seconds and five minutes. When the set time ends, the light output returns to standby mode.
A 90W 2 module Cetus LED low bay light from Enlighten was installed in the car park entry. This fitting actually represented a net increase in energy consumption compared to the existing T5 fixture (68W including ballast), but it was necessary to improve the light levels in this area.
All lights were replaced on a one for one basis, with each parking bays having a standard 12 chip bulk head installed. The fittings lighting the driveways are permanently on, and the ones approaching a turn have side-emitting optical lenses to ensure good visibility.
An extra incentive
Coorparoo’s Woolworths is located in an area with electricity supply constraints, which means it qualified for a Peak Load Reduction Reward. Energy-saving scheme Energex rewards businesses within the area that contribute to reducing demand on the network during peak periods by replacing lighting with more energy efficient lighting. The reward payment given to Woolworths is estimated to be $500 for this upgrade.
The savings in numbers
The new LED lighting will save an estimated 77per cent energy in the car park area, which equates to 30,504 kWh per year. The project capital cost was $21,250 after the incentive payment, with a project payback calculation from energy and maintenance savings of 2.7 years.
According to Dwyer, the project has been well received. ‘The Chamaeleon fitting is perfectly suited to our undercover car park operation and I have received an immense amount of positive feedback from the tenants,’ he said.
Dwyer is planning to retrofit another shopping centre’s undercover carpark lighting with in early 2015.

When H&M arrived on Australia’s shores last year, it did so in style with a vast, mostly LED-lit flagship store in the former General Post Office building in Melbourne.
The building’s long history, and its 18 meter high ceiling, presented the facility team with a challenge of respecting its heritage while ensuring that the fixtures were as easy to maintain as possible.
This has been achieved mainly with linear LED luminaires, recessed from existing ceiling pockets, which focus the light down the central spine of the building’s three-storey glazed atrium.
Lighting designers kept in close contact with Heritage Victoria throughout the project and ensured that the lighting installation was fully reversible and didn’t do any damage to the building surface.
As well as recessed ceiling fixtures, linear LED luminaires have been placed high up to uplight the ceiling and emphasise the columns and the geometric shape of the atrium.
Lower down, mannequins sitting on swings and posing on podiums are lit with narrow-beam metal halide spotlights. The spotlights are placed in pairs on the columns around the atrium with linear LED uplights positioned in-between the spotlights to highlight the top part of the columns above.
The arcade arches around the building are lit with linear LED fixtures concealed within the structure. All light sources are warm white with a colour temperature of 3000k.
Using mainly LED light sources means the store has achieved an electrical load of 12W/m2 for the downward light and 10W/m2 for the architectural lighting to the arches, trees and ceiling structure.

STARQUALITY
LUX magazine reports. First impressions count at one of London’s top music venues. Robert Bain reports. The names of London’s major theatres and concert halls have become iconic, and few more so than the Hammersmith Apollo.
The Apollo first opened as the Gaumont Palace cinema in 1932, with a huge seating capacity of over 3,000, and lavish front-of-house facilities including a large first floor restaurant.
In the 1960s it was renamed the Hammersmith Odeon (a name by which many still know the venue), and became a concert hall. The list of musicians to have graced the stage reads like a who’s who of the past half century of popular music.
FADED LUSTRE
But like many such venues, the once opulent Apollo has not had the best of care over the years. As its use evolved from swish cinema to sweaty rock n’ roll venue, the Apollo’s lustre faded.
Now the Grade II listed building is in the midst of a rebirth.
When Kate Bush made her comeback this August after a 35-year hiatus, she did it at the Apollo, and the place looked better than ever.
Owners AEG Live and Eventim have embarked on a major refurbishment. The façade and front-of-house areas have already had their former glory restored, with the latest technology achieving effects not possible before, and bringing the best out of the building’s architecture. Next up will be the auditorium, which is set to be revamped next year.
THE NEW OLD FASHIONED WAY
The Apollo wanted to use fittings that matched the originals that were installed years ago – but not all of them could be saved or converted to use new light sources. Some were fitted with modern light sources, while others were recreated completely, based on photos.
The new lighting was designed by James Morse Lighting Design, with products supplied by Great British Lighting, Philips Color Kinetics, LightGraphix, Concord, Crescent, Radiant, Applelec and controls specialist Pharos
