Energy Efficient Lighting

CAT | Philips LED

The IoT, in which every device can communicate with every other device – even a smart bedcover can ‘talk’ with devices such as Philips’ Hue LED lighting system – is fast becoming a fact of life, like it or not. But how are the IoT technologies evolving, what are the benefits and how about the risks? And how about a wider context? James Hunt explains:

Internet and device growth…and the IoT could represent 200 billion devices by 2020. Some say even this is conservative! 

Mario Morales, IDC

The IoT is as of countless ‘things’ that are fitted with uniquely identifiable embedded devices that are wirelessly connected to the Net.  These ‘nodes’, as the ‘things’ are called, can send or receive information without human intervention. The nodes can even be fitted to animals (to track or find them), and indeed to people and their clothes – for a variety of reasons we may or may not like.


To achieve this, every ‘thing’ – which could be an LED light source or luminaire, or thermostat, or an industrial controller, for example – must be uniquely identifiable through its embedded computing system, yet it must also be able to interoperate within the existing Internet infrastructure. Such devices are proliferating fast.

With its myriad such devices, including sensors and actuators that ‘talk’ to each other wirelessly and on the Internet, the IoT brings with it an astonishing ability to measure, monitor, and analyse data. This includes, for example, consumer behaviours and buying habits – and not just consumers either, as all businesses can benefit.

Such monitoring and analyses can be used to determine future product developments that will revolutionise the ways in which we live and do business. For the vast majority of homes – made ‘smart’ by IoT devices – everyday life will be enhanced by technology, particularly in terms of entertainment and comfort.

To take just one example – Google and Philips Lighting have got together for Nest Lab’s intelligent wireless thermostat and home automation devices to work with Philips’ Hue IP-connected LED lamps – OSRAM is in on the act too.

 

Connectivity is the word

When the IoT is augmented with devices such as sensors and actuators, it can then encompass increasingly important technologies such as smart homes, buildings, grids and cities, as well as intelligent transportation. These devices collect useful data with the help of various existing technologies and then autonomously flow the data between other devices – such as those that use Wi-Fi for remote monitoring. But how, in brief, does such connectivity work?

Firstly, there are several types of connectivity used by the IoT. These are:

* Personal Area Networks (PAN)
* Local Area Networks (LAN)
* Neighbourhood Area Networks (NAN)
* Wide Area Networks (WAN).

PANs and LANs are those that most domestic and small business IoT installations are likely to use directly and these are also the ones that the majority of electrical contractors and installers will be involved with.

 

Those IoT devices that use a PAN with a smartphone will use the smartphone as the gateway to the Internet (WAN). Devices in a smart home or automated building can connect to a LAN and find their way to the Internet too.

So IoT devices use, as the name implies, Internet connectivity, but smart devices that are part of an overall IoT can also use other enabling technologies, such as RFID and near-field communication (NFC), optical tags and quick response codes (a now common example is the QR Code) and a whole range of wireless (Wi-Fi) topologies. The latter include Bluetooth Low Energy, low energy wireless IP networks, ZigBee, Z-Wave, LTE-Advanced (high-speed communication specification for mobile networks) and Wi-Fi Direct (Wi-Fi for peer-to-peer communication without needing to have an access point (AP).

It remains to be seen if any one of these becomes pre-eminent.

Important IoT issues

Away from IoT issues that will affect electrical wholesalers, contractors and installers directly – as opposed to regulators, data centre developers and owners, specifiers and IoT / network device manufacturers – there are a number of problems that will need to be addressed to ensure successful wide-scale take-up.

For example, thousands of IoT devices signaling and sending data to each another take both CPU consumption and a surprising amount of energy. This costs money and has carbon emission implications, so IoT devices should use the minimum energy possible. Though this will not normally affect electrical distributors, contractors and installers, ultra-low-power wireless chipsets should be used in IoT devices and low power networks – such as Bluetooth low-energy, ANT, ANT+, ZigBee, ZigBee RF4CE, Wi-Fi, Nike+, IrDA and the near-field communications (NFC) standard.

Bandwidth take-up is another IoT connectivity issue. Bandwidth on a cellular (mobile) network is expensive, especially with hundreds of thousands of IoT devices sending request/response signals to a server – the result is that the server farm will need to be large enough to handle all the data. With the potential for many billions of devices (possibly even trillions longer term), this will be a huge problem that must be addressed.

Another issue is presence detection of IoT devices. This provides the exact state of all IoT devices on a network and shows immediately when any device drops off the network – or when it comes back on. In this way, the IoT devices can be monitored (and fixed if a problem occurs).

And for those IoT devices that ‘live on their own’ – such as trackers – the connectivity to the wider Internet can be tricky.

Finally, it is important to note that the Internet is not simply one network, and heterogenous networks, proxy servers and security firewalls can all disrupt connectivity. So a fully functioning, all-encompassing IoT is not with us yet as many issues need to be sorted. Even so, the vast majority of Voltimum users will not need to confuse themselves with this level of granularity – most already available smart devices they install for domestic use as part of the IoT will be simple to install and commission. They are already.

At light speed!

Although Wi-Fi has not been in the public domain for too many years – apart from computer routers – it is now an established means of data communication. It is fast and increasingly reliable. Importantly, it is quick and easy to install because expensive and disruptive hard wiring is not needed.

However, there’s a new kid on the block that is even faster – far faster – and it has its own set of advantage and disadvantages. Let’s look at it briefly here:

This important newcomer is Li-Fi, which has as its analogue Wi-Fi, but being based upon light (which travels at 186,000 miles/s) is very much faster – many times faster than conventional Wi-Fi – and possibly up to 10 times cheaper.

Li-Fi (or Light Fidelity) is a form of visible light communication (it can also use infrared and near ultraviolet). It is bidirectional and fully networked and has been described as a ‘new era of wireless connections’. With claimed speeds of up to 224 GBps (though mostly lower), this new technology could enable a high-definition film to be downloaded in seconds.

The change to Li-Fi, when it comes, will be driven mainly by the electrical and lighting sectors through LED lighting. Li-Fi will turn every LED lamp into wireless access points (APs), which effectively allows any user to move between sources without losing the connection. The LED lamps act as the medium to deliver networked, mobile, high-speed communication in a similar manner to Wi-Fi (but much faster). All this then becomes another enabler and part of the IoT.

Li-Fi has the advantage of being suitable for use in areas sensitive to electromagnetic waves such as aircraft cabins, hospitals and nuclear power plants, because it does not cause electromagnetic interference. However, the light waves cannot penetrate walls, so reducing Li-Fi’s scope, and there may be problems in bright sunlight. Such difficulties will have to be addressed before there is widespread use of Li-Fi, but there’s no doubt that this new technology is creating great excitement.

Already there are examples of Li-Fi in the market. For instance, Philips Lighting has developed a system for shoppers in stores. They have to download an app on their smartphones, which then work with the lighting LEDs in the store. The LED light sources can pinpoint where the shoppers are located in the store and give them corresponding coupons and information based on which aisle they are on and what they are looking at.

Li-Fi is very likely, therefore, to change data communication; importantly for the electrical and lighting sectors, it will also generate much-needed new revenue.

Ethernet and Industrial Ethernet with the IoT

The IoT doesn’t only have domestic applications; it has a vast potential in commercial, retail, hospitality and public building sectors too. Then there’s industry – in particular, manufacturing and process plant. A connectivity protocol that is very widely used in IT is Ethernet and its industrial counterpart is the much more rigorous Industrial Ethernet. These, together with Wi-Fi are effectively enabling the Manufacturing Internet of Things – otherwise known more usually as the Industrial Internet of Things (IIoT).

The (IoT) has morphed from its RFID origins to one that encompasses all networked devices, both within and without a manufacturing operation. The big drive to adopt IoT in manufacturing has coincided – says Automation World – ‘with a concurrent enabling trend toward use of Industrial Ethernet and wireless (Wi-Fi) network technologies within the production environment’.

In addition to intelligent sensors and machines, the IIoT also takes in ‘Big Data’, cloud computing, analytics, mobility and what is termed universal visualisation. Manufacturers are aiming to implement the IoT or IIoT to optimise assets, increase production efficiencies and, therefore, improve business performance. This is achieved by gathering data from the many sensors, actuators, other devices, machines and controllers operating on the shop floor. This data is then made globally available via a cloud or similar infrastructure platform to those operators who have the authorisation (and for security’s sake, only them), so that they can monitor and analyse it – and act upon it if necessary.

The application of the IoT and IIoT to industry is really beyond the scope of this article, and relatively few Voltimum users are likely to be involved in the sector, but it is important to note, even so, how the IoT is having a crucial impact here already.

Security and safety will be crucially important

There’s that proverbial fly in the ointment, of course, and this is security, which will be of paramount importance if the future all-encompassing IoT is to work as intended, safely and securely. This is because just about everything (and everybody) will be connected together. The possibilities for hacking, denial of service, fraud and utility- and city-scale disruption are huge.

Indeed, security concerns are developing faster than even the IoT itself. This is especially so when it is considered that IoT devices will be (and already are) connected to smart grids, smart cities, water and gas utilities, energy organisations, transport etc. And domestic smart meters will connect homes to power utilities. Knowing this, the potential for catastrophe is certainly clear, whether by accident, by virus intrusion or via hacking.

So among the many considerations will be to ensure that when sending or receiving data, the IoT device or server must have proper authorisation for that (and every such) action. Also, an IoT device is dangerously vulnerable when it is listening to an open port out to the Internet – ports should not be open, despite the need for bidirectionality. End-to-end encryption between devices and servers will be crucial.

But security doesn’t just mean ensuring that your IoT system is secure from hacking; it also involves privacy and whether you can be spied upon, because the IoT holds the possibility that organisations will be able to intensify personal surveillance. And if they can, you can be sure they will try.

Issues include when someone sells a house with a smart thermostat or garage door, how does the new owner ensure former users can no longer access these devices? And how do manufacturers protect against intrusions into smart TVs and theft of data collected from device cameras and microphones? Such issues have to be addressed to make the IoT safe and secure, now and in the future.

Standards

It is clear that IoT and connectivity standards are already a crucially important, though already divisive topic. After all, how will devices connect to others without interoperability standards? Yet, many devices so far conform to a wide range of often non-interoperable standards.

Cross-industry open source organisation, the AllSeen Alliance  (among others) believes that the IoT cannot meet its full potential without an open platform to ensure interoperability between devices from different manufacturers.

Then there’s research by ON World, which finds that the wireless standard ZigBee, already being used by many IoT devices, continues to increase its share of the IEEE 802.15.4 and smart home markets. By 2020, the study claims, ZigBee standards will be used in eight out of 10 of the 802.15.4 chipset shipments.

Furthermore, the Thread Group announced last year that it had completed the specification and documentation for its IP-based wireless networking protocol for low-power connected devices in the home.

These represent just a very few examples of potential interoperability clashes for connected and IoT devices. Therefore, organisations such as the Institute of Electrical and Electronics Engineers (IEEE), the Industrial Internet Consortium (IIC), and the European IoT-A (Internet of Things – Architecture) project, among others, are looking to provide architectural frameworks that define relationships between IoT domains and devices, as well as appropriate security schemes.

As these few examples show, it’s clear that there is much work to do as far as standards and interoperability are concerned.

And finally….

For the future? Well, the World Economic Forum makes five predictions for the IoT, bearing in mind that in the past year alone, IBM has invested £2 billion in its IoT business unit, and AT&T announced a record 1.6 million connected device net additions, including one million IoT-enabled cars, in Q3. Earlier in the year, Samsung declared its commitment to connecting everything it sells by 2020, and GM stated that its OnStar 4G capabilities will generate £242 million in profit over the next three years.

The predictions are:

– That the ‘security of things’ will take centre stage.

– We will stop counting the ‘things’ in favour of more important success metrics to put a premium on the quantifiable impact of new services.

– For the first time, more new cars will be connected than not.

– Low-power wireless area network (LPWAN) technologies will not go mainstream because the technologies are still in their infancy.

– The IoT market will align around a more precise lexicon, meaning that ‘business savvy enterprises will demand accuracy and accountability, resulting in clearer definitions from IoT solution providers’.

Can power over Ethernet transform how we control lights in the workplace?

The humble Cat 5 cable – now capable of carrying power to your lights as well as data

Lux reports: LED lighting is helping buildings around the world slash their electricity bills because the amount of energy needed to run LEDs is so much lower than that consumed by traditional forms of lighting.

But lower energy consumption isn’t just about saving money and being kind to the environment. It’s starting to demonstrate other benefits too.

The electrical load of LED sources is now so low that you don’t even need mains cables to power them – you can use standard network cables, so it’s easier and cheaper to connect and control your lights.

This technology is called ‘power over Ethernet’ (PoE) and, as the name suggests, it’s a way of providing power for electrical equipment through Ethernet cables – the same ones that already form the backbone of the IT network in your office.

Ethernet uses ‘cat 5’ (or more recently cat 5e or cat6) cables – the kind you plug into your router, with the plastic clip on the end that clicks into place.

Cat 5 cables are really designed to carry data, not power. But as long as the load is below a certain wattage (up to about 60W at the moment) they can power and communicate with devices at the same time. Which turns out to be really useful.

So what are the advantages for lighting? Well, everyone knows that wiring up a new lighting system can be an expensive headache, and to install a control system, you’ll need yet another network of wires up in the ceiling, along with the power cables.

If you want control but can’t face all that wiring, you’ve got three options: send the data wirelessly (using specially equipped drivers), send the data over your power cables (using power-line communication, offered by the likes of Lumenpulse and Echelon), or send the power over your data cables – in other words, PoE.

The great thing about using cat 5 cables for this kind of thing is that they’re cheap to buy and even cheaper to install – no need for an electrician, just click the cables into place and you’re away. Philips, one of the suppliers of power over Ethernet systems for lighting, reckons installation is up to 25 per cent cheaper than conventional wiring.

But that’s just the beginning – the real savings are in the longer term.

The next big advantage is the level of intelligence that an Ethernet-based control system can bring. Every light becomes a point on a network, with its own IP address. That makes it easy to control and monitor them (including remotely over the web), and if your light fittings incorporate presence sensors, temperature sensors, light sensors and so on, you can track that data too.

PoE brings lighting into the ‘internet of things’, allowing you to connect your lighting to other devices and systems in the building, such as heating, ventilation, IT services and security. The facilities manager has a single system that shows exactly how the building is being used.

Up and running

Philips already has a PoE lighting control system up and running at a new Amsterdam office building occupied by accountancy firm Deloitte.

UK-company Prolojik also has a power over Ethernet system, Light Matrix, that it sells with luminaire makers Future Designs and Phi Lighting. The system is installed in a meeting room at the offices of PricewaterhouseCoopers in central London, to power and control 20 direct/indirect luminaires.

Other companies working on PoE for lighting include Iowa-based Innovative Lighting and California’s Nuleds.

To use Prolojik’s power over Ethernet system, you need a black box called an Ethernet switch, which converts AC mains power to the DC that goes through the cat 5 cables (achieving 10 per cent efficiency savings over a standard setup where mains power goes all the way to the driver, Prolojik says). Once the switch is installed, the electrician’s work is done. It can power up to 3kW of lighting: it has ports for 48 cables, each of which can be used to power and control 60W of lighting – enough for maybe one or two luminaires each. Any luminaires rated up to 60W can be used with the system, although it does require Prolojik’s Dali drivers.

Mark Vincent, commercial director of Prolojik, says the ease of installation is a big draw for clients. ‘When we’ve been presenting this, I’ve been apologising to electricians and contractors, because we’re taking their business away,’ he says. But the real benefits are in fully addressable control of lights, and the long-term energy-efficiency benefits.

As with Prolojik’s system, the Philips system works with third-party luminaires, and talks to any existing control systems that may already be installed in a building. Philips’ PoE system is based on a network of small Ethernet switches, so it can be scaled from powering a handful of luminaires to 1,000 of them.

Jeff Cassis, senior VP of global lighting solutions at Philips Lighting, says: ‘You can extract whatever data you want, whenever you want. Not only can you monitor energy consumption per light source, you have this really granular ability to look at what’s happening on my floor or building, aggregate that and understand how people are using the spaces. If you have multiple sites or buildings, you can look at how different buildings are managed. You could see how to use certain areas better, cool areas down that aren’t being used and make extra savings due to occupancy.’

Cairo Opera house

On the occasion of Philips sixth consecutive Cape Town to Cairo roadshow, Philips today unveiled the newly illuminated Cairo Opera House.
– Philips 21st century connected LED lighting technology revitalises Cairo’s Opera House – bringing new life to this iconic building, whilst also reigniting cultural pride and saving energy.
– Over the past five years the Philips Cape Town to Cairo roadshow has spread light across Africa improving and beautifying cities, and illuminating iconic landmarks

Philips has provided the Cairo Opera House with a stunning makeover that has radically boosted the beautification of this iconic building. By using its latest LED lighting technology, which has a lifespan of up to 50,000 hours(1), Philips will enable the Opera House to reduce its energy consumption by up to 80% compared with conventional lighting currently used in the Opera House.

Reigniting cultural pride

The Cairo Opera House is a cultural landmark renowned for leadership, excellence and imagination. It has carved itself a significant position in the cultural landscape of Egypt and the Middle East. With its appealing mix of high-quality traditional events, and its unique venues as well as its state of the art facilities, the Cairo Opera House is exceptionally suited to fulfill its mission to become a representation of art in Egypt and across the world.

Tamer Abol Ghar, Country Manager Egypt & General Manager Africa, Lighting Professional End User Sales, commented : “It is with great pride that we can today unveil the stunning LED makeover of the Cairo Opera House. The lighting not only magnifies the beauty of the renowned building, but it will also enable a significant reduction of energy consumption at the Opera House. As the global leader in LED lighting, we have made massive strides in recent years with regards LEDs, and it’s really quite remarkable to witness the effect the lighting of a building or a landmark can have on an entire city or region. We have no doubt that the people of Cairo will enjoy the Opera House for many more years to come, and hopefully as a result of the dynamic new lighting it will be seen in a completely new light not only by locals, but by the world.”

Philips’ new lighting concept focused on highlighting the importance of the building as a source of cultural pride. Located in the southern part of Gezira Island, this iconic building now houses new Philips dynamic lighting, which ensures it is visible from anywhere up to half a kilometre away on the River Nile. The new Philips lighting design has guaranteed that the viewing points of the Opera House are the main feature, with light and shadow applied in such a way that the building’s structures are also emphasized.

The initial challenge for Philips’ design team was to give the iconic Opera House a more innovative look while maintaining the authentic and historic atmosphere of the Opera House. The Philips team applied its innovative Vaya LED lights which create an endless spectrum of colors to highlight the features of this architectural masterpiece, and allowed Philips to introduce a vibrant ambience that changes depending on the performance happening inside the Opera House.

The usage of intelligent RGB (Red, Green & Blue) flood lights on the façade of the Cairo Opera House turns the hall into a landmark that is highly attractive, adding visual comfort as well as an expressive environment at night. The domes of the building have been illuminated using intelligent RGB floodlights with wide beam angle to highlight the octagonal base shape

The entire project at the Cairo Opera House took Philips four months to complete – this included the design, implementation and installation of 160 Philips latest Color Kinetics Vaya LED RGB (Red, Green & Blue) Lighting luminaires.

Ninth and final stop of the Cape Town to Cairo roadshow

Cairo marks the grand conclusion of Philips’ annual pan-African Cape Town to Cairo roadshow that kicked off on 11th May 2015, in Cape Town.  Cairo is the ninth stop on the roadshow’s journey which covered 12,000 km across 11 cities and 8 countries over a period of 4.5 months. Cape Town to Cairo has gained significant momentum over the past five years, allowing Philips to get to the heart of some of the key issues facing Africa – including Mother and Child Care, the rise of non-communicable diseases, energy efficient LED and solar lighting solutions, as well as shining a spotlight on the need for clinical education and training.

The 2015 roadshow continued to drive the conversation around sustainable energy solutions. As part of Philips dedication to improving healthcare in Africa many substantial innovations and partnerships were announced and Philips illuminated a number of iconic buildings, which will leave behind a permanent legacy, while also reducing energy consumption.

Philips and Cisco form alliance to target global office lighting market

Lux reports: Ringing the changes: connected lighting using PoE technology means office workers can adjust the lighting to suit their preference

Philips and Cisco have formed a global strategic alliance that will combine Philips’ LED based connected lighting system with Cisco’s IT network to address a global office market estimated to be worth EUR 1 billion. The Alliance is designed to bring the benefits of the Internet of Things in offices to facilities managers, building owners and office workers.

The pair will combine Philips’ connected office lighting system using Power over Ethernet (PoE) technology with Cisco’s network technology. Light points in the Philips system, equipped with sensors and software applications, can be connected using Cisco technologies.

The lighting network creates a pathway for information and helps enable new services. The system can provide data to optimise user comfort and improve the office environment and office workers can personalise their lighting via their smartphones.

To showcase how Philips and Cisco can work together to unlock the benefits of the IoT in offices, Cisco is installing a state-of-the-art Philips connected lighting system at its Canadian headquarters in Toronto. Philips and Cisco will also collaborate on a joint go-to-market strategy.

Bill Bien, SVP, head of strategy and marketing, at Philips Lighting, said: “Our alliance has two of the world’s biggest and trusted lighting and connectivity brands working together to bring the Internet of Things to life in offices and commercial buildings across the world. Customers will receive the best energy efficient lighting experience in the connected world and be able to use information acquired from their connected lighting system to save energy, reduce costs, improve productivity and optimise their workspace environment. Lighting that is connected to highly secure, reliable IT infrastructure will form the backbone of the smart office of the future.”

Together Philips and Cisco aim to accelerate adoption of this technology in the market and deliver increased connectivity, comfort and efficiency.

Edwin Paalvast, SVP EMEAR, Cisco and executive sponsor of the Cisco – Philips Alliance, said: “The world is becoming digital, and by working with Philips, we can help building owners more quickly digitise their lighting networks to drive better user experiences and efficiency. By partnering with Philips, we are delivering a reliable PoE-powered LED lighting solution using a highly secure IT network.”

Typically, lighting is responsible for 40 percent of a building’s electricity use. The pair estimate that nearly 80% in energy savings and reduced building maintenance costs can be realized by managing, integrating and controlling a Philips LED connected lighting system through a network with Cisco.

To make offices more comfortable, office workers can personalize and adjust LED lighting to their preferences and tasks. For mobile access, office workers can use a smartphone app to access other building services through a communications network.

“The possibilities of this connected lighting system are endless,” said Richard Lees, senior project manager at CBRE, a commercial real estate and investment services firm. “There are so many capabilities of this system that we haven’t even explored yet.”

This underpass near King’s Cross and St Pancras stations in North London is saving money on energy and maintenance since it had its old metal halide lights replaced with specially designed LED road tunnel luminaires from Philips.

The St Pancras Road underpass is a busy road, cycle and pedestrian route to the two major train stations, as well as providing access to Camden Council’s new offices. It was previously lit by around 100 twin-lamp metal halide fittings and the council saw an opportunity to visually improve what had become a gloomy and uninviting area. This was a ‘spend to save’ initiative to take advantage of energy-efficiency gains and lower maintenance costs while also reducing carbon emissions.

The lighting design was carried out by Philips and the new luminaires were installed by main contractor SPIE. SPIE’s John Broster said: ‘The previous luminaires were fitted into the soffit of the underpass and as this is a concrete strutted roof it would have been impractical to alter it. We needed a solution that could provide a direct replacement for the existing fittings.’

The stainless steel luminaires have been installed on a one-for-one replacement basis, to provide energy savings of more than 50 per cent. The new lighting has increased light levels and uniformity to remove the gloom, while the 4000K neutral white colour temperature has created a better and more inviting visual environment for users of the underpass. The tunnel feels safer and more pleasant.

The project also provided an ideal opportunity to make better use of lighting control. ‘As this is a short underpass the lighting only requires one-step dimming and we were able to adjust the existing system, using high light levels during the day and dimming at night to minimise the contrast for drivers entering the underpass,’ said Broster.

The council has achieved a significant reduction in energy consumption, while also reducing maintenance costs as the luminaires are expected to be virtually maintenance-free throughout their lifetime, and should pay for themselves in about five years.

Until recently, this tunnel in Stoke-on-Trent, England, had to be regularly closed to change failed lamps, causing disruption to drivers.

Now, those old fluorescent and high-pressure sodium lamps have been replaced by over 600 linear LED luminaires, arranged in unbroken lines. It looks way better, and the lights should last about 10 times as long as the old ones – 20 years instead of two.
The new lights, supplied by Philips, will also use significantly less energy.
To help drivers adjust their vision when entering and leaving the 284-metre tunnel, the lights near the ends are brighter than the ones in the middle, providing 156 cd/m² of light near the exits and >2.0 cd/m² (dimming to >1.5 cd/m² at night) in the middle. They are also dimmed as the day progresses, to match the level of natural light or streetlighting outside the tunnel.
I have reduced my overall maintenance costs, saved a substantial amount of money in energy costs, reduced the carbon footprint and reduced the risks for the operatives’
Paul Diamond, Amey
With a projected life of 20 years, the energy savings and reduced maintenance costs are expected to generate around £850,000 ($1.3 million) of savings.
The work was done by engineering services firm SPIE for Amey, the principal contractor for the Highways Agency. Paul Diamond, tunnel manager for Amey, said that since the installation of the new LED lighting, ‘I have reduced my overall maintenance costs, saved a substantial amount of money in energy costs, reduced the carbon footprint and reduced the risks for the operatives.’
The new system complies with the updated standard BS 5489:2 2008 and is designed to provide better uniformity and colour rendering than the old scheme. Because the lights are in an unbroken linear arrangement, any failures (which are unlikely in any case because of the long life of LED lights) would have little effect on the overall scheme. A point-source installation, on the other hand, can easily fall below minimum lighting levels if just one or two lamps fail.
And because the new system uses LEDs, the lights can also be instantly turned back on after a power failure (unlike high-pressure sodium which needed time to cool down first), are fully dimmable, and work well in low temperatures.
The result of the upgrade project is that the annual energy consumption of the tunnel lighting has been reduced from 660 MWh to 154 MWh, a saving on energy costs of nearly £64,000 ($100,000). The tunnel will also save around £28,000 ($44,000) on maintenance, so the total annual savings will be around £92,000 ($144,000). The predicted savings over the expected 20-year life of the installation are predicted to be nearly £850,000 ($1.3 million).
