Rugby High School enjoys ‘significantly improved’ illumination from energy saving LED upgrade

The comprehensive LED-based lighting upgrade is expected to deliver annual savings of £12.5K and a return on investment of only 4.5 years.

Increasing instances of lamp failure, a recognition that the quality of the illumination could be better, and a desire to take advantage of energy savings accruing from the latest LED technology informed a recent upgrade at Rugby High School in Warwickshire. The major, site-wide overhaul was undertaken by Energys Group and funded by Utility Rentals’ operational lease scheme.

As the school’s Business Manager, Allan Kerr, explains, “it had been clear for a while that the old lighting was nearing the end of its useful life. Lamps were beginning to fail on a more regular basis, meaning that we were spending more money on replacements and maintenance. In addition, we were working on plans for a new sports hall, and if we had kept with the existing lighting we would have had to increase our electricity supply.”

Having engaged the services of energy efficiency technology specialist Energys Group to advise on the project, it quickly became clear that a comprehensive LED lighting upgrade would both reduce demand on supply and enable substantial energy savings. Consequently, the two parties began work on a lighting overhaul to encompass the main hall, music theatre, classrooms, science labs, gym, sports hall, corridors, staircases, communal areas and the languages block.

‘Dramatic improvement’

The resulting installation draws on LED products from across the Energys Group range, and includes tubes, panels, down-lighters, spotlights, wall-lights, outdoor fittings and flood-lights. Mere weeks after the project was completed – with a minimum of disruption to the operational practices of the school – it was evident to school management and personnel quite how much of an improvement the new systems had delivered.

“For the first few weeks after the deployment staff kept coming up to me to remark upon the new lighting. In particular, the increased standard of illumination in the main hall, gym and science labs was singled out for specific praise,” recalls Kerr.

Whilst the quality of the lighting was immediately apparent, its benefits in terms of energy savings will become more evident over the medium to long-term. As a result of the massive upgrade – which ran to 712 new LED lamps and 575 LED fittings – Energys predicts a return on investment of just 4.5 years. Annual energy savings are expected to total £12.5K and approximately 104,985 kWh’s, with a reduction in CO2 emissions of 55.84 tonnes per year.

Raj Gunasekaran, Business Development Manager at Energys Group, says that “the improvement in lighting conditions across the entire site is very discernible, and of course the energy savings are also going to be very welcome – particularly in the current challenging economic climate for the education sector. But it’s also important to highlight that improved lighting often translates to happier pupils and staff, meaning increased productivity and quality of work.”

‘Brilliant scheme’

However, there is another important element in the mix here and that is the funding provided by Utility Rentals. Having investigated some other schemes but concluded that they were unlikely to deliver the finance in the necessary time-frame, Kerr instead applied to the Utility Rentals operational lease initiative, with Energys Group providing guidance and assistance throughout the process.

As Utility Rentals director Steve Mattey explains, the scheme is fast, guaranteed and “available for any school in the country – no matter what size or establishment type. The rental scheme is cash-positive from day one, with repayments covered by the energy costs saved. The repayments are also fixed and won’t go up year on year, and can even be deferred until 12 months after the lighting has been installed.”

The Rugby High School application was successful, and Kerr reports that he was struck by “how straightforward the process proved to be. I am also pleased with the fact that if any failures occur, replacements will be provided at no cost. It really does take the risk element out of what has been a substantial undertaking.”

Reflecting on the completion of another comprehensive lighting upgrade in the education sector, Gunasekaran says that “the benefits Rugby High School is now experiencing as a result of implementing the latest LED lighting technology are now increasingly commonplace throughout this market. At Energys we are able to support this transition with a comprehensive range of LED solutions, so it’s no surprise that we have many comparable projects on the agenda for the rest of 2017.”


Brightest in the class

The benefits of switching to LEDs have been well documented in recent years. Facilities managers, tasked with reducing energy costs as well as carbon emissions, have opted to use LED luminaires – often retrospectively – and as a result have been able to enjoy significant savings. Applelec managing director Ian Drinkwater discusses how the latest generation of LEDs is driving innovation forward.

It is well documented that LED lighting systems offer significant benefits compared with traditional schemes, generating less heat and providing up to 50,000 hours of illumination per luminaire, leading to a longer lifespan as well as lower maintenance costs and reduced CO2 emissions. On average, LED luminaires use around 75% less energy than traditional sources, while reducing carbon emissions by around a third.

Many of the early snags of the first generation of LED systems – a ‘cold’, dimmer light, the higher cost of replacement luminaires and so on – have now been overcome. Technological advances are rapidly driving development forward, with the latest LED modules boasting reduced power consumption and carbon emissions while emitting the highest quality light.

What’s more, these advances are changing the way we use lighting throughout buildings as a whole. Inspired by research and development, lighting is no longer confined to use in ceiling pendants and wall lights. Increasingly, designers are incorporating illumination into fixtures and fittings to draw attention to important areas such as reception desks and information areas, while attractive, decorative wall panels add considerable interest.

Large-format lightboxes are used to display information or advertising messages, or alternatively to create a centrepiece attraction which is both stunning to look at and economical to run.

Technology in practice

The first direct arena in Leeds is one example of how new-generation LED technology has been utilised to produce a stunning showpiece which was both easy to install and is cost-effective to power.

Applelec supported corporate branding specialists Nebula Creative in the design and installation of two rock ‘n’ roll lightboxes for the arena’s VIP bar, renamed the Black and White Lounge, pairing SloanLED PosterBOX 3 LED modules with a textile framing system.

The display features around 240 classic album covers from artists who have played the venue, such as Robbie Williams, Lionel Richie and JLS, since it opened in September 2013. The covers have been incorporated into two large-format lightboxes – one almost 10 metres long and the second just under five metres long – both with a textile frame.

Using LED tape or ribbon for such a scheme would be time-consuming to fit. However, using the PosterBOX 3 modules, the feature was assembled quickly and easily.

High brightness illumination is achieved across a width of up to three metres using the SloanLED PosterBOX 3 system, with just two rows of facing modules are required to provide light. In addition, the product significantly reduces the installation time required to populate a lightbox in comparison to the use of LED tape or ribbon.

The result is an eye-catching, bright and evenly lit feature which has transformed one of the arena’s most vital areas, yet was easy to fit with modules along just the top and bottom edges of the frame. The installation is so bright it is even noticeable outside the venue, through the windows of the VIP bar.

Energy efficient

Benefits are about more than just looks. Using 56 PosterBOX 3 modules, the entire system is extremely cost-effective, drawing just 756.8W. This compares favourably with alternative equivalent systems, with a similar LED tape installation using 14.4W tape using approximately 2344W – and a fluorescent scheme using an estimated 86% more energy than the PosterBOX 3 modules.

As products develop, the potential for use increases. The PosterBOX3, for example, is impressively bright yet slim, with the ability to fit into depths as shallow as 50mm for a single-sided application. Ease of installation is another bonus – the modules are available with a ‘peel and stick’ option as well as regular mechanical fastenings, eliminating the possibility of tape becoming unstuck.

The modules are compact enough to fit into spaces where previously only LED ribbon systems could go, yet provide better performance in terms of luminance, energy efficiency and longevity. A module spacer is incorporated into the design, eliminating the need for measuring and consequently reducing the installation time.

What’s more, LED ribbon carries both a higher failure rate potential and a greater heat output than the PosterBOX 3 modules, as well as requiring a larger number of drivers for powering purposes.

Where next?

With technology moving on apace, many manufacturers of LED luminaires still do not offer warranties beyond one or two years. While many system manufacturers are still not committing to longer than a couple of years, some such as SloanLED are underlining their confidence in the reliability and longevity of their products by offering a five-year warranty.

Applelec is a trade supplier and manufacturer of signs, displays and lighting, based in Bradford, West Yorkshire. In January, it became an official UK distributor for SloanLED systems, including PosterBOX 3 modules. Applelec has used SloanLED systems within fabricated signage and lettering for many years and as a result, has a comprehensive understanding of the products and how to get the best from them.

Green Tourism gets behind LED in light of Halogen ban

In light of the recent EU halogen bulb ban, Green Tourism are backing LED lighting as a sustainable and cost effective alternative as they report businesses could be saving a massive 90% on costs with the one simple switch.

Jon Proctor CEO of Green Tourism, the world’s largest sustainable certification programme of its kind, explains more about why switching from halogen to LED makes business sense.

“By replacing halogen bulbs with new LED alternatives, businesses will not only become more eco-friendly but will also save money on energy bills and bulb costs.

“Once the fashionable lighting choice, halogens were a ‘must have’ in the 90s and early 00s. At this time alternative low energy products were shunned because they poked out of fittings, were slow to light up and gave a hospital style illumination that was not suitable for the hospitality industry.

“This is no longer the case, however, as technology advancements have meant there is no need for high energy consuming Halogens, which were typically between 25-50watts. Over the last 3 years LEDs have really taken over. They are high-powered units that have great illumination and can now beat halogens for quality, performance, life span, eco-friendly disposal and cost.

“LEDs and halogens can be used in all the same ways, the biggest difference is cost and maintenance. A halogen will require 25-50watts to illuminate where an LED will require 3-5watts, a huge 90% saving in running cost.

“Using experience from working with top hotels around the UK it is estimated the restaurant will run a light for over 5000 hours per year. It is likely halogens would need replaced at least once and maybe 2-5 times during this time, while the LED alternative should have only used half of its life with some units rated at 50,000 hours or 10 years in this case.

“The table below highlights the cost in energy and bills of the two lighting options over a ten year period:

Halogen LED
50,000hrs / 10 years 10-50 bulbs 1 bulb
Watts 25-50w 3-5w
Energy Consumption 2500kWh 250kWh
Cost (15p/kWh) £375 £37.50
Carbon footprint over period 900kg CO2* 90kg CO2*

*CO2 calculated using average CO2 emission per kWh for electricity generated in the UK in 2015 (Source DEFRA)

“Switching from halogen to LED makes total business sense, not only does it help towards the Government target of an 80% reduction in carbon by 2050, it will reduce energy bills, lighting costs and go towards a more sustainably run organisation.”

LED Eco Lights launches intelligent LED lighting battens

  • LED lighting battens provide 65% energy savings
  • Twin-tube fluorescent luminaires can be upgraded in ten minutes

LED Eco Lights has added SMART Sensor technology to its Goodlight™ G5 LED battens, allowing the luminaires to be grouped and respond intelligently to a building’s lighting needs. Warehouses and industrial sites can reduce their lighting energy bill by up to 65% by replacing fluorescent lighting in offices, production areas, warehouses, car parks, loading bays and other areas with SMART Goodlight G5 LED battens from LED Eco Lights.

Goodlight G5 battens now feature SMART Sensor, a built-in RF wireless sensor which allows full control of the luminaire. The sensor not only allows the luminaire to respond directly to occupancy, motion and light levels, but also allows it to communicate with other grouped luminaires. G5 LED battens can be grouped together, with one master controlling the behaviour of multiple slaves. The feature allows lighting to be controlled much more intelligently. For example, lights can be switched on in anticipation of occupants entering an area for example as they progress along a corridor or up a flight of stairs. The Goodlight SMART Sensor includes Daylight Monitoring and Tri-level Dimming. All options and settings can be programmed and adjusted by simple remote control.

Goodlight G5 LED battens are a direct drop-in replacement for standard 2ft, 4ft and 5ft length single and twin tube fluorescent fittings, but draw just 20W, 30W, 40W or 50W respectively – 65% of the energy of the fluorescent equivalent. The G5 has a lifespan of 50,000 hours, over triple the typical fluorescent tube, giving site operators further savings in maintenance budgets. The G5 delivers very high levels of light output, offering 110 lumens per Watt with a 120° beam angle for optimum spread. Light replacement can be funded from operating budgets using a pay-as-you-save lease option.

Housed in a sleek body, the Goodlight G5 is shielded by a high density rubber seal, giving it fivefold protection against the environment. The seal offers IP65 protection against water, dust and corrosion plus the fitting can withstand exposure to frost, snow and ice. It can operate in extreme temperatures from -20 to +50°C, and is suitable for use in cold storage areas. The G5 fitting is glass-free making it suitable for food and drink production environments. It has an impact protection rating of 1K08.

LED Eco Lights are specialists in LED lighting for retro-fit applications, and estimates an existing fluorescent batten can be replaced with a G5 luminaire in just ten minutes. The G5 can be recessed, suspended, surface-mounted or seamlessly linked and is supplied with stainless steel mounting clips as standard for quick and simple installation.

Goodlight G5 LED batten luminaires are available in three colour temperatures: daylight, natural and warm white. They are fully dimmable, and can be controlled via a DALI or 0-10V interface in addition to the RF wireless remote. An optional emergency backup battery is available.

Commenting, Saima Shafi, sales and marketing director at LED Eco Lights said, “Goodlight LED lighting technology offers more efficient light at lower cost, without the drawbacks of other low energy lighting technology. Our LED lamps and luminaires reach full brightness instantly, and are virtually maintenance free with no ballasts or starters needed. They are also free of the migraine-inducing flicker of traditional tube lights, and contain no heavy metals making them easy to dispose of safely and are much less hazardous in the unlikely event of a breakage.”

Businesses are able to fund lighting replacement programmes from their operating budgets by taking advantage of the company’s BrightPlan LED leasing scheme. This allows the replacement lights to be paid for directly by the energy savings and the customer will own the lights outright at the end of the lease. LED Eco Lights is offering businesses a free site survey which will provide a detailed breakdown of suitable replacement light fittings, the installed cost and the return on investment from savings on energy and maintenance costs. They also guarantee the G5 and other Goodlight fittings for five years, making installation risk-free.

Venture upgrades high bays to create premium industrial luminaire

Venture Lighting Europe has created yet another highly efficient, energy saving solution for industrial lighting schemes with its new and advanced VLED Highbay Pro. The luminaire is an upgrade of the company’s established VLED IDT Highbays which have been used for numerous applications across the UK.

As the range’s premium product, the VLED Highbay Pro is similar to the original high bays in terms of application, however is more advanced in performance and output, whilst offering a choice of reflectors and beam angles.

Like all of Venture’s VLED luminaires, the Highbay Pro offers a more sustainable and energy saving alternative to fluorescent or HID lamps, which are associated with high running costs and regular maintenance requirements. The superior performance and low energy output of the VLED Highbay Pros will significantly reduce these costs and requirements to provide a fast return on investment.

Available in 100W, 150W or 200W, the VLED Highbay Pro offers a solution for all application requirements and allows companies to use various outputs across the scheme to save energy where possible. The luminaire also offers an excellent efficacy of 100 lumens per circuit watt with an overall package of up to 20,000 lumens to offer optimal light levels across the application. Having such high levels of light can significantly improve the safety of the environment which is particularly crucial in sites that use storage and machinery.

The VLED Highbay can be mounted at heights up to 12 metres with a standard beam angle of 120 degrees for a wide light distribution to cover large areas of factory or warehouse floors, which reduces the number of luminaires needed across the application. Aluminium or borosilicate glass reflectors can also be added to narrow the beam angle to 60, 70 or 90 degrees for a more targeted distribution in aisles or corridors. These reflectors do not affect the quality of light transmitted and are able to withstand the high heat that is generated by the LEDs.

Like Venture’s original VLED Highbays, the Highbay Pro utilises the company’s innovative Integrated Driver Technology (IDT) which incorporates the LED driver into the body of the luminaire. This advanced technology removes the need for a separate driver which will allow the luminaire to achieve its expected 50,000 hour life. This ensures that a lighting scheme does not lose any light from failed products which could compromise the safety of the environment.

The luminaire also adopts the original VLED Highbays’ incorporated smart heat-sink unit to maximise the dissipation of the heat from the LEDs. This built-up heat is known to damage the performance of the luminaire and reduce its life expectancy. Having this highly efficient thermal management system also ensures the 50,000 hour life is achievable. The luminaire carries a five year guarantee.


Why wireless control brightens the effect of LED lighting

LED lighting is revolutionising the lighting industry and creating completely new market conditions. However, unlocking its full potential has been hampered by a lack of simple and easy to install industry standard solutions enabling personal control, energy conservation and compliance with increasingly stringent building standards. To fulfil all of these requirements, LED control based on standardised wireless technology is the way forward. By Matthias Kassner, Product Marketing Director, EnOcean

With LEDs replacing old lighting technologies, new control capabilities enable building owners to achieve higher energy efficiency rates and increased comfort. Fulfilling this potential requires selecting a suitable control solution. As the lighting market is still evolving, different standards and architectures exist for lighting control to cover the comprehensive requirements of changing colours, dimming, occupancy-based on/off, demand response or sophisticated daylight harvesting.

Stringent regulations

Building owners demand reliable systems at reasonable costs, which forces the lighting industry to provide a comprehensive but easy to install control solution. This goes hand in hand with regulations, such as the EU Directive for the Energy Performance of Buildings, which became a vital part of building regulations in a drive for greener buildings. It aims to make energy use in buildings transparent by issuing Energy Performance Certificates (EPC) as well as identifying and developing new opportunities for a reduced carbon footprint.

Besides this, green building certification programmes such as LEED or BREEAM call for integrated control of building areas for the achievement of the maximum number of points. Here, the meaning of lighting control is still significant: 30% of lighting energy consumption is still wasted on average when rooms are not in use.

The limits of wires

One option for installing LED lighting control is a wired system. This is mainly suitable for simple use cases where all lights are connected to the same bus and set to the same light intensity. But wiring complexity grows significantly once the system is required to control a set of lights together. Furthermore, an upgrade from a simple scenario to an advanced control system cannot be implemented without costly changes to the existing wiring and the controller. In addition, it is almost impossible to include sensors, for occupancy detection or daylight harvesting for example, to achieve optimal energy saving rates.

For retrofit projects in particular, the installation of wired controls can be complex, costly and time-consuming. Modernising an existing building with wired control systems requires the addition of dedicated control cabling to each individual lamp. Each element, such as switches, sensors and lights in these systems requires dedicated cabling as well.

Wireless flexibility

An alternative to a wired system is wireless control. It has increased in popularity in the last decade due to advances in radio technology and the emergence of standards which enable seamless communication between different devices. The key advantages of wireless control are the ease of upgrading existing buildings and expanding a system at any time. No new control wiring is required for existing lights; they simply have to be upgraded with wireless control units. Wireless control systems can potentially also provide greater installation flexibility if units within the system do not require dedicated cabling for power.

Building standard

Several standards already exist for wireless communication in a building automation system. The energy harvesting wireless or so-called EnOcean standard is one of the most established. It is defined by the EnOcean Alliance, a consortium of international companies of the building automation industry. The wireless communication uses the 868 MHz frequency, which delivers a distance of up to 30 metres in buildings and has no interference impacts from local Wi-Fi or Bluetooth devices. RF reliability is assured as wireless signals are less than one millisecond in duration and are transmitted multiple times for redundancy. These characteristics make the standard well suited for wireless lighting control in larger buildings with a few hundred wireless sensor nodes up to several thousands.

Elimination of batteries

The standard is optimised for ultra-low power communication, which allows the use of battery-less, self-powered sensors and switches. For lighting control purposes, the two main energy sources for battery-less, wireless devices are motion and light. Self-powered switches use kinetic energy to generate a wireless signal for controlling and dimming. The second energy source is provided by miniaturised solar cells which harvest ambient light and convert it to electrical energy. This approach is particularly suitable for light level or occupancy sensors. Based on standardised application profiles, energy harvesting wireless devices from different vendors can seamlessly communicate with each other. This approach of open connectivity and interoperability offers the conditions for an integrated LED control.

Holistic approach

The energy harvesting wireless standard enables a complete wireless LED control system for retrofit projects. Solutions based on this standard include LED controllers, solar-powered occupancy and light level sensors, kinetic-powered light switches and a remote commissioning software tool. The controller wirelessly communicates using the energy harvesting radio standard at 868 MHz. Via this protocol, it receives wireless telegrams from all linked self-powered wireless switches and sensors and adjusts its outputs accordingly. It provides a switched output for the supply of connected loads as well as a control output to dim connected loads. Multiple fixtures can be daisy-chained, e.g. 20 each 30W fixtures or 10 each 60W fixtures.

This system can support a wireless daylight harvesting application, for example. Daylighting means that the light level is automatically adapted to the amount of available natural light in a room measured by light level sensors. In a typical commercial building, it is possible to save between 20% and 30% of energy with such an automated control system.

Basis configuration

The wireless controller supports several usage scenarios. In a very simple configuration only wireless light switches will be connected for manual control of the lights. If desired, it is possible to configure an auto-off timer which turns the lights off after a certain amount of time as is usually used in stairwells. Another basic installation can be implemented by connecting occupancy sensors, which sense motion in a room and send wireless signals to the controller, which controls LED lighting according to occupancy. Both the standard on/off configuration as well as switching between two dimming levels is possible. The latter case is important in applications where a minimum light level must always be maintained. Instead of an on/off configuration, the occupancy sensors’ signals can also be used to set different dimming levels in the range between 100% and 0%.

The combination of occupancy sensors and rocker switches enables the user to manually turn on the light, whereas the occupancy sensors automatically switch off the light after a pre-configured period of time when the room is unoccupied. Light can be automatically turned back on if occupancy is detected. In this scenario, the occupancy sensor can also be used to switch between a high and a low illumination level and the switch can be used to turn lights off completely.

Sophisticated control

The addition of a light level sensor allows the implementation of daylight harvesting based on open loop control. This means that the light sensor, positioned facing a skylight or window, measures the amount of available natural light and regulates the output light level accordingly. The lighting controller will then only add as much artificial light as needed. In a simple configuration, the system will change between two levels, a minimum and a maximum dimming level, depending on light levels reported by the light level sensor and signals from occupancy sensors and switches. In addition, it is possible to set up a more sophisticated daylight harvesting scenario which supports continuous dimming based on five sampling points which can be defined via remote commissioning software. In both scenarios, illumination will change smoothly by means of adjustable speeds which can be independently configured for manual changes via rocker switches and automatic changes based on sensor signals.

Configuration over the air

More advanced settings, such as thresholds, dimming levels, ramp speeds, or timers can be changed wirelessly via a remote commissioning interface. By employing a Windows-based laptop computer equipped with a remote commissioning tool, an installer can locate wireless devices throughout the facility, logically connect the controller to switches and sensors, and configure settings in the controller over the air, all completely without physical access. It is also possible to link the LED controller via a central unit or a gateway to a supervisory building automation system like BACnet or KNX.

Low installation effort

Thanks to wireless technology, all of these scenarios can be set up quite easily at low installation costs and only require a minimum of maintenance. Therefore, building operators can fulfil regulatory requirements and achieve immediate energy savings and increased comfort with low investments and a fast return on investment (ROI). The wireless sensors and switches can be flexibly and optimally positioned without requiring repair to walls or ceilings. Due to the self-powered operation they even eliminate the need for changing batteries.

The LED controller’s compact size enables flexible installation inside of or next to electrical boxes and fixtures so it can be easily wired out of sight using standard wiring practices. Wireless lighting control also enables a migration path, starting with simple control and expanding the system with advanced functionalities such as scheduling, demand response or remote commissioning later on. As the LEDs can be digitally addressed, they can also communicate with each other and a central control. This enables the building of groups of light, which create optimised scenes in accordance with changing situations.

Seamless communication

Wireless standards offer valuable benefits to LED control by following an integrated approach consisting of accessories, software and easy-to-use commissioning tools. At the same time, they combine control functionalities and networking abilities with a consequently standardised communication. The wireless technology allows users to easily install, retrofit, move and commission LED lighting control even in complex systems achieving large scale economies.


Benefits of LED Lighting – Up Front and Personal

In the world of lighting, LED has become an unstoppable force. It is now difficult to envisage a refurbishment or new build that does not feature LED lights within its lighting scheme. There are huge benefits in terms of energy and cost savings with lighting bills cut by up to 90%. Yet the widespread adoption of LED lamps and fixtures has been held back by confusion among specifiers and commissioning clients. British manufacturer Integral LED has chosen a novel approach in an attempt to demystify the process of retrofit lighting by presenting the tangible bonus of a swap to LED upfront and online.

Contractors and homebuilders can now access a free energy saving calculator that allows everyone to assess the benefits of LED retro-fit lights. The website is open to all and does not require any buying obligation on behalf of the user. It provides a practical means of sourcing a replacement lamp, downlight or panel by initially helping the user to visually identify an LED alternative to an existing incandescent, halogen or fluorescent light-source. The Integral LED website then offers a range of products displayed according to the total amount of light (lumens) output for each replacement light. It is therefore possible to select a whole inventory of lamps and fittings for a current building project; but it is here the extremely useful bit of the calculator kicks in!

Use of the LED retro-fit light calculator is intended for professional builder and commissioning client alike. Effectively, choose your new lights for each room of the building. Decide on the lumen levels required. As each space or area is calculated the specifications are stored. Ultimately the complete project and the required replacement lights are added to a total. As the lights are picked and multiplied according to the number required for each room – the real benefits are collated. Using two usage scales, an accurate cost savings profile is totalised for each lamp, for each interior space and ultimately for the whole building. A default 3 hours usage per day at 14 pence per hour electricity cost is customisable for each lamp, and usage figures for panels and downlights are similarly adjustable – allowing the user to flexibly model the 24 hour lighting regime of a complete home or office.

The results of a switch to LED lighting always has a profound and pleasing effect on clients. The Integral LED calculator provides clear cost saving results for each retro-fit light. It also works out a payback time for each light and the build project as a whole, against the level of investment incurred up-front. For the environmentally conscious (as we all should be) the level of carbon CO2 reduction is displayed within the results summary – which allows us to hold our head up (for a while) on climate change! Very usefully, the whole exercise can then be shared with a customer as a pdf document, email or printed off as a reference for a site meeting. Additionally the Savings Calculator (as well as the complete Integral LED website) has a responsive design that delivers a user-friendly experience on tablets and smartphones, in addition to PC based web browsers. This is ideal for a spontaneous demonstration of the benefits of LED lighting in our daily battle against costs.

Electrical management specialists saves 60% with Venture LED lighting scheme

Venture Lighting have partnered with Hertz Electrical Distribution to supply over 250 of its latest LED technology luminaires to one of the largest electrical management specialists in the UK. Two warehouses have been installed with Venture’s VLED Midibay Elite wide beam luminaires as an energy efficient alternative to the previous high-wattage lamps, whilst also benefiting from the Enhanced Capital Allowance (ECA) programme.

Installed at 9m and 7m heights, the new lighting scheme replaced 270, 400w Highbay and 250w Lowbay metal halide fittings in the warehouses, saving them over 60% in energy costs. Supplied in 100w and 135w versions with a white gloss luminaire body, the VLED Midibay Elites are installed with Digital Addressable Lighting Interface (DALI) dimming controls and combined PIR and Daylight sensors as a part of the company’s sustainable objectives.

The electrical management company specialises in electrical distribution and automation management as well as carrying out installations of components for energy management and has a great knowledge of energy saving technologies. The company was introduced to Venture Lighting by Hertz Electrical Distribution, a key solution partner to Venture.

The Digital Addressable Lighting Interface (DALI) technology, a lighting control protocol assisting the management of light and energy, determines the level of light delivered at a particular time or place by means of communication with the integral DALI CP sensors. Passive infrared occupancy sensors have been used in the warehouses to automatically detect activity and ensure that light is only provided where necessary. Similarly, the DALI dimming controls combine with the daylight sensors to detect daylight levels and control the lights depending on the amount of natural ambient light available.

Available in 67, 100, 135, 167 or 235 watts, the VLED Midibay Elites are high performance luminaires, producing 108 lumens per watt (lm/W) and a colour temperature of either 4000k or 5000k to replicate natural daylight. With a 50,000 hour life and 5 year warranty the luminaires require minimal maintenance thus avoiding unnecessary disruption to the work flow within the warehouse. The longevity of the LED array is also enhanced by the highly effective thermal properties of the luminaire design, preventing them from becoming inefficient through overheating which is an issue often overlooked with high power LED arrays.

Venture’s VLED Midibay Elites can be specified with a narrow or wide distribution and the option of clear or opal diffusers. The fittings can be surface mounted or suspended to provide lower level lighting making them particularly suitable for industrial lighting schemes, such as warehouses, where different levels of lighting are required across the

Tridonic delivers significant savings at Bournemouth International Centre car park

45% reduction in carbon emissions achieved in first 12 months

The installation of approximately 400 Tridonic LED lights in the multi-story car park at Bournemouth International Centre has delivered significant savings in its first twelve months. The project to replace the original fluorescent lights was undertaken by Littledown, a specialist lighting control’s company that has a long standing relationship with Tridonic.

“We are investing in energy-saving initiatives across our venues which is vital to cutting energy dependence, costs and CO₂ emissions,” says Peter Portnoi, Head of Facilities Management for BH Live, the social enterprise which manages Bournemouth International Centre in partnership with Bournemouth Borough Council. “Last year, our on-site electrical crew came up with the concept and designed a new, energy-efficient lighting scheme for our 650 space multi-storey car park at Bournemouth International Centre. They teamed up with the Dorset-based, family-run company, Littledown Lighting to install the system and, thanks to the new Tridonic low energy LED installation complete with motion sensors, we have saved 134378 KWh of power and reduced carbon emissions by 45% in just 12 months.”

Steve Reid, managing director at Littledown said; “The biggest challenge with this project was that the car-park needed to remain open throughout the three month refit but with careful planning we were able to keep disruption to a minimum. The existing fpluorescent gear trays were replaced with Tridonic’s LED Boards and approximately 400 LCAI drivers. In addition to the significant savings in energy that these new fittings have delivered we expect a significant reduction in the number of lamp replacements and all the fittings carry the standard five year Tridonic warranty.”

“Lighting in a car park is something that the public gives little thought to unless they feel uneasy due to its poor quality. By investing in this new LED based solution, BH Live has delivered a high quality light solution at Bournemouth International Centre and also made a significant saving in terms of energy use, which benefits everyone;” said Martin Thompson of Tridonic.

Light Efficient Design sets University of Nottingham on path to brighter lighting

LED Retrofit comes of age following 1000 lamp installation to replace University’s campus-wide sodium, providing enhanced light quality, energy performance and pedestrian safety

Light Efficient Design EMEA has announced The University of Nottingham has successfully completed an initial project to replace exterior Low Pressure Sodium (LPS) campus lighting with retrofit LED lamps manufactured and supplied by Light Efficient Design, the US-based world leader in retrofit LED HID lamping technology.

This was in response to the University’s rising energy costs with lighting accounting for approximately 20% of the total annual UK energy bill, its commitment to reducing overall carbon emissions by 40% by 2020, and the requirement for brighter campus lighting for added pedestrian safety.

Installed at the main 300 acre University Park Campus in Nottingham, Light Efficient Design’s retrofit solution has enabled the existing lighting columns, heads, holders and fittings to be reused. Approximately 1000 retrofit LED units were ordered for re-lamping the external areas of the University Park Campus – comprising around 750 lamp tops – while leaving sufficient quantities for potential requirements elsewhere. Local contractor, Manor Maintenance, was chosen to manage the installation following The University of Nottingham Estates Team’s tender request.

Nottingham’s University Park Campus is widely regarded as one of the largest and most attractive in the country and has been a Civic Trust Green Flag Award Winner every year since 2003 – the only university campus to achieve this status. This required the conversion to modern high quality Light Efficient Design LEDs from the incumbent yellowy orange LPS lighting to be achieved non-invasively, with minimum disruption to day to day campus life, and in keeping with the surrounding environment and buildings architecture. Maintenance budget constraints meant that ease of LED product installation and ongoing reliability was also a prerequisite in the interests of optimising labour and servicing costs.

For the Campus driveways, pathways and roadways Light Efficient Design specified its 8023 35 circuit watt LED retrofit lamps, which, compared to the incumbent 58 circuit watt LPS offering, provide a 40% energy saving. Following quick and easy bypassing and disablement of the existing HID ballasts and control gear, the simplicity of the retrofit lamp design allowed the installer to reuse the lamp fittings and fixtures, enabling each post to be retro-fitted in around 15 minutes. A number of Light Efficient Design 8028 20 watt bollard and wall pack LED retrofit solutions were also supplied for replacing existing 70 watt Metal Halide lamps.

Said Richard Clayton, Electrical Engineer for The University of Nottingham, Estates Department: “We chose the Light Efficient Design retrofit LED solution as it ticked all the boxes. At a third of the cost of traditional non-retrofit LED lamp post lighting, we recognised their retrofit lamps to be considerably more affordable as they do not require replacement of the existing lamp columns or heads. The quick and easy installation also enabled labour savings through greater productivity.”

Added Gavin Scott, the University of Nottingham’s Environment Manager, “We are confident the LED solution is already providing a sustainable solution which will help us in our mission to drive down our energy costs and carbon emissions. The lamps are also greatly enhancing the quality of light for improved student, staff and visitor safety and their simple, unobtrusive, design and installation ensures the overall look and feel of our Campus environment is preserved.”

The success of the initial University Park Campus installation has already resulted in The University of Nottingham planning to extend retrofit lamping to its nearby Sutton Bonnington Campus. This will entail the installation of approximately 250 Light Efficient Design retrofit LED lamps. Discussions are also underway for a similar project at the University’s Jubilee Campus. Email:
