End of last year, the T-line was installed in the Zeeburger Tunnel.Following the successful installations in the Vlake Tunnel and the Heinenoord Tunnel, Vialis (commissioned installer) and Rijkswaterstaat (Dutch authority for Infrastructure and Transports) alsoopted for the specialLED tunnel luminaires from Indal for the replacement project in the tunnel near Amsterdam. A tremendous improvement of the light quality and reduction of the energy and maintenance costs are the main results.

The Zeeburger Tunnel is the third tunnel in the Netherlands to be equipped with the T-line. The T-line has several advantages compared to equivalent tunnel lighting solutions. T-line is equipped with Indal’s proven REVOLED™ technology, the surface of the T-line is smooth, which makes the luminaire easy to clean. In addition, lamps no longer need to be replaced during the normal service life of the installation, which significantly reduces the maintenance costs for Rijkswaterstaat. Moreover the LEDs will operate for at least 15 years.

Vialis and VolkerRail (subsidiaries of VolkerWessels)
In 2010, the Vlake Tunnel became the first tunnel in the world with an LED line lighting installation. The Heinenoord Tunnel followed in the spring of 2011. Based on the experiences gained in the two tunnels – energy savings of 50% and an improved vision and guidance for road users – the choice was once again made for Indal’s T-line for the Zeeburger Tunnel.Both the interior lighting and the entrance lighting are equipped with LEDs.

The Zeeburger Tunnel was first opened in 1990, the 546meter tunnel is part of the A10 motorway (eastern ring road near Amsterdam). The tunnel passes under the canal Buiten IJ and connects the Zeeburger Island and the North of Amsterdam.

Maintenance is being carried out on the tunnel by VolkerRail. In June 2011, the company was given the assignment by Rijkswaterstaat to replace the installation. To do so, VolkerRailasked for the expertise of Vialis, another VolkerWessels company, which specialises in mobility solutions. Preparations began even before the end of the summer holiday season. The actual work on the tunnel began in October. “By then we had also approached a number of lighting suppliers and compared their products. Indal emerged as the best of them all”, says Johan Bal, project manager at Vialis and responsible for the project. “The selection was made together with Rijkswaterstaat”, he says. “A major advantage of Indal was that it was the only supplier in the Netherlands that already had experience with LED lighting in tunnels. We then investigated at whether they could meet the set of requirements for this project.”

LED line lighting
The entire Zeeburger Tunnel is equipped with Indal’sLEDT-line tunnel luminaires. That means that the T-line interior lighting (48 LEDs and 50 watts) have been combined with the T-line entrance lighting (72 LEDs and 130 watts). To remove the old luminaires – each of which weighed 200 kilograms – Vialis designed a mobile working platform: a container module on a lorry in which all of the necessary equipment was available, such as a generator and an air treatment unit to enable the work to be carried out safely. Moreover, as a result of this solution, road users experienced very little inconvenience caused by the work activities. “It also immediately provided a physical safety barrier for our employees, which was moveable and it was not necessary to close an entire tunnel for four consecutive weekends. This enabled us to carry out the work at night, while keeping one lane open for traffic.”

The preference was for line lighting, which offers greater comfort for the road user. Thanks to the lower energy consumption of LED, line lighting is now once again feasible.

The luminaires have been placed directly next to each other with no space in between.

In combination with the clear, cool white light of the LEDs, which is easier for the eyes: it does not cause an irritating flicker effect, such as with point lighting. “In the entrance lighting the lenses were installed asymmetrically, so that road users are not forced to look directly into the light”, explains Johan Bal. This is one of the major light technical advantagesof the T-line: the LEDs in the luminaire can be aimed very precisely: on the ground, on the tunnel wall and at the desired angle. The special T-line entrance luminaire enables effective contraflux lighting. By allowing the light distribution at an angle of less than 70 degrees, the light reflects well on the road and does not glare the road user.

Operation
The base countcomputer, the operating system for the lighting, is operated remotely from the Northwest Netherlands Traffic Control Centre, which operates and monitors all tunnels in the province of Noord-Holland. As Johan Bal explains: “Generally speaking, the installation works automatically: the light intensity is controlled by means of a light cell, but the light cells can be adjusted and dimmed manually from the control centre.” The luminaires are delivered with a pre-installed plug. The cable runs through a cable conduitand drop pipeto the central tunnel console, where all of the driver boxes are located. “Twenty standard luminaires or ten entranceluminaires are connected to each driver box, however, each has its own driver.

The luminaires for each driver box can be dimmed from the computer by means of an address system.”

Our employees are inspired, committed and driven to develop and deliver the right LED products tuned to customer demand. And we at Indal also want to inspire our customers with our LED lighting solutions and demonstrate what LED lighting can add to public spaces to improve and enhance the live in cities and villages.

A successful story on LED and efficient lighting
The success story is a familiar one: with the Stela in 2009, Indal introduced the first LED luminaire, which was developed based on the revolutionary REVOLED™ technology with energy savings up to 60% and strongly focussed on lighting in residential areas.

Since then, new luminaires with REVOLED™ have been introduced in the market. Parallel to this, Indal developed RETROLED™: a smart solution for replacing the light source in conventional luminaires with LED engines so that, also with these applications, enormous energy savings of up to 50% are achievable.

World premiere: Luma, LED luminaire for traffic routes

All LED products from Indal will be on display at the stand. Special attention will be given to the Luma. The Luma has been on the market since the end of last year, but has not yet been presented at an international trade fair. This latest solution is especially intended for traffic routes. It is a logical extension after the Stela family (for residential areas and city roads), T-line (for traffic tunnels), Ocean and Element family (residential areas and city centres) and Dot (indoor lighting). Like the Stela, the Luma is also growing into a family: last year, Indal introduced the Luma 2 (maximum 120 LEDs) and the Luma 3 (maximum 200 LEDs).  In other words, a suitable LED solution is now available for all situations.

At Light+Building, Indal will also show a preliminary concept of the smaller Luma 1 and the even smaller MiniLuma. Rinco van Rijn explains the idea behind these new products: “They are intended for roads within cities that require less lumens output and other light classifications. To offer a complete family and enable traffic route authorities and municipalities to select a consistent shape and design from the motorway right the way to the city centre.” The introduction of these new Luma’s is planned for 2013.

Complete offering of LED solutions

Indal’s stand at Light+Building is completely new. The stand is open and inviting with a fresh and sophisticated design. The stand is divided into the application areas that Indal uses. In that way, the floodlights for illuminating buildings, monuments and statues can be found in ‘Architecture & Landscape’. The city beautification solutions can be found together in ‘City Centres’, complete with modular brackets and poles and matching street furniture. In this area we will also show a prototype of a new ambiance LED lighting solution that certainly will inspire our visitors.

The third part is ‘Residential Areas’, where the Stela family is presented, followed by the application Traffic Routes , with Luma LED road lighting and T-line LED tunnel lighting. The products confirm that we are pioneers when it comes to LED applications for public lighting. Another important application area is indoor lighting where Indal presents its latest product developments focused on energy efficiency and reduced Total Cost of Ownership.  “Step by step and very focussed, we have covered all application areas in anticipation of the demand of the market.”

During the last Light+Building, in 2010, the stand had more than 4,000 visitors. Now, Rinco van Rijn expects to double that number. That popularity can be related to the reputation of the tapas and Spanish ham that will be served once again this year.

Acquisition of Indal by Philips

Indal was recently acquired by Philips, a global leader in lighting, with recognized expertise in the development, manufacturing and application of innovative lighting solutions. Philips’ CityTouch intelligent management system for outdoor lighting will be exhibited on the Indal stand at Light +Building 2012. For more information on Philips at Light + Building 2012, please visit http://www.lighting.philips.com/main/connect/events/light_building/

LED lighting technology is ready for almost application areas. Wim Visser, Indal Product Manager explains his view on the future of LED lighting and the latest success from Indal LED lighting solutions: Stela, Luma, etc.  More information and stories from Indal LED in Indal Newsroom and website.

Suffolk County Council is pursuing an ambitious target of becoming the greenest county. To succeed, this aspiration requires a commitment from every individual, community and business in the county. Each will be required to embrace the climate change challenge and work together on a long-term plan to improve the environment.

The council has many exciting projects currently underway. One of the most inspired being led by Electrical Services Manager, Richard Webster, working with a team of colleagues from both within the county street lighting department and also the current term maintenance contractor Carillion. The team needed to find a solution that reduced the carbon emissions, address rising energy costs as well as reducing visits to street lighting units for lamp changes and other maintenance purposes on major arterial routes, where traffic management requirements have been particularly costly and restrictive in nature. One such route within the centre of the county is the A1120 ‘Cedars Link’ on the outskirts of the town of Stowmarket.

After careful consideration, the team chose to switch from traditional street lighting to LED units. The Council has been installing Stela LED street lighting from Indal in numerous projects relating to smaller roads, footpaths and residential areas since 2009. It felt that their latest Luma LED model was now suitable to be applied to larger, main roads on a fit and forget basis. The proven high energy savings and carbon reduction of the models chosen along with the minimal six year maintenance cycle, contributed strongly to the decision.

To further improve the environmental benefits, Suffolk County Council has introduced a Central Management System (CMS) where lighting units in residential areas, subject to pre-determined criteria, can be switched off remotely between the hours of midnight and 5.30am. The units on more major roads, including this installation, can be dimmed during the night when traffic is much lighter and there are fewer pedestrians.

The council anticipates using this Intelligent Street Lighting will provide substantial savings in their energy bills in the region of £850k per annum.

Suffolk has an ambition to reduce its carbon emissions by 60% by 2025. LED Street Lighting, together with the introduction of part night lighting and dimming through the CMS, has the potential to deliver energy savings resulting in a CO2 reduction of over 4000 tonnes by April 2013. The Cedars Link scheme alone will reduce the energy consumption for that road its energy consumption by around 63% and almost 1000 tonnes of CO₂ over a 25 year period will be saved, contributing significantly towards these targets.

Councillor Guy McGregor, Suffolk County Council Portfolio Holder for Roads, Transport and Planning, commented:

“Introducing the new lighting system across Suffolk has not only helped us to save money and reduce our carbon emissions but has also given us the flexibility to control our own lights, and respond to the local community needs”

Creating the Greenest County was launched in 2007 by John Gummer MP. It is a partnership organisation made up of all local authorities, businesses and the voluntary sector. Since that time the partnership has gathered an impressive momentum and now plays a significant role working with local communities and businesses to reduce their carbon footprint and save energy.

Richard Webster remarked:

“We were very impressed with the lighting levels and uniformity achieved for this particular installation. The CMS installation is gathering momentum and 30,000 units have been installed within the last 6 months. The use of both the Luma and Stela products in conjunction with the CMS has enabled us to achieve the dimming requirements and energy saving, and this, coupled with the part night lighting is also enabling us to achieve our carbon reduction target”.

Tongeren, the oldest town in Belgium and a member of the Most Ancient European Towns Network, has recently awarded Indal with the innovative project of designing and implementing the lighting for the city’s basilica. Tongeren has an extremely rich culture and historic background, as the city is covered with ancient monuments that add to its charm and beauty.

In the town square alone stand the statue of Ambriorix, the Town Hall and, what is considered by many the city’s most extraordinary monument, the Basilica of Our Lady. Listed as UNESCO World Heritage, the basilica’s gothic tower stands over the city, demonstrating its unrivaled beauty. The authorities of Tongeren decided to embark upon a lighting project which would accentuate the ancient monuments of the city and thus a ‘Light Council’, consisting of a group of citizens, was formed. This council, with the suppport of the municipality, asked several lighting manufacturers to study the project and present their proposals for creating lighting for three monuments in the city: the Basilica, the statue of Ambiorix and the Town Hall.

Lighting project and solutions by Indal Belgium

The ‘Light Council’ studied all the proposals presented, taking into account numerous factors including design, innovation, creativity, vision and performance, and, after several months of deliberation they chose Trilux to carry out the project of the lighting of the Town Hall and the statue, whereas Indal was given the priviledge of focussing on the masterpiece that is the Basilica. Thus, bearing in mind the importance of the assignment, Indal carefully selected a number of different sized products from the Inled range, as well as projectors Mario IZR, Sirius IZS, Zeus IZX and T-Lines. The installer specialist MAES Industrïele Verlichting provided their services for the project and the result is outstanding. Phase II of the project will begin soon, and it will be the main streets and the medieval walls that will be the focus of this stage. The products that Indal have carefully selected for these landmarks in Phase II are Ocean System Plus and for the Moeren Gate, which dates from 1379 and still remains intact, will be lit by Stela’s.

Following the success of the Stela for mostly residential areas and the T-line for tunnels, Indal introduces a  new LED luminaire for traffic routes. The new luminaire  will enable savings on energy costs and CO₂ emissions from 10 to 40%. Considering that these installations involve high wattages, this adds up considerably. LED is about to experience new levels of success. “We can now offer a suitable LED solution for all situations,” says product manager Wim Visser proudly. “From the smallest alleys to the busiest highways.” The new launch involves two differently sized Luma luminaires: the Luma 2 and the Luma 3.Preview

Next step

LED lighting has the future, an opinion which is getting more support. While developing the new technology, Indal focused first on the Stela. “That was a conscious choice: with its application area – such as residential areas – with the largest potential for energy savings,” explains product manager Wim Visser. “These areas need huge numbers of lighting installations and relatively lower lighting levels. There you achieve your energy targets as quickly as possible. Another important factor was that these luminaires are located in residential areas and are therefore close to people and politics. That’s how we generated approval and acceptance for this new method of lighting – in terms of both lighting and appearance.”

“Then our T-line for tunnels clearly demonstrated the robustness and reliability of our technology. The system complies with all the special requirements (lighting and maintenance) for road tunnels. This took us to the next step: the move from residential areas to motorways. Which is how we arrived at the Luma concept.”

Luma is intended for use on access roads, ring roads, inter urban main roads and motorways. Visser: “Higher lighting levels are required on these roads. Depending on the road type, they now use 50 to 400 Watt SON-T lamps. The challenge was to cover that complete range with the Luma family – and that’s exactly what we did.”

Huge nominal savings

Compared to residential areas, small and efficient lamps are generally already used on traffic routes. Their light is easier to direct and to capture. Moreover, there are strict standards not just for lighting levels, but also for the degree of ambient lighting, so that the available light is utilised more efficiently. Those two factors mean that in percentage terms the energy savings achieved with the Luma are not as high as for the Stela, which often produces savings of over 60%.

However, the Luma is no less attractive. “People tend to focus on the percentages,” Visser explains. “But on traffic routes each lighting point requires higher wattages and therefore the absolute figures are counting. Of course, it’s difficult to generalise given the diverse wattages and lighting situations involved. But going from 50 up to 400 Watt, you can often end up with savings of around 10 to 40% (without dimming). Then we’re talking about huge numbers of kilowatts and enormous amounts of money and CO₂.”

However, certain problems had to be overcome. “In the Stela, the LEDs are positioned with reasonable spacing – at optimal thermal distance. For each LED, you have a particular lighting volume and depending on how much lumen you need for an application, you calculate the required number of LEDs. For traffic routes, you need much more lumen packages and LEDs. If we had kept to the same LED distances as in the Stela, we had ended up with luminaires three or four times bigger. That’s obviously not a practical option.”

“So we had to come up with a different solution. In order to position the LEDs closer to each other, we had to make it possible to create an acceptable luminaire size. That required a totally different lighting application.”

Pulling strings…

The optical lighting technology in the Luma is called OPTIFLUX™. ‘Flux’ means flow of light and emphasises the fact that the system involves large lumen packages that are optimally captured with this technology. Three different lens-optics were developed to meet the requirements of the various M(E) lighting classes and road geometries. Those lenses are positioned close to each other, covered with a flat glass bowl. The printed circuit board (PCB) with LEDs is positioned in a white frame. The frame is made of highly reflective plastic and directs the little light that is shining to the side downward in the direction of the road.

Wim Visser & Luma

Initially, it seemed as if the use of a glass bowl was going to reduce the lumen output per Watt, but during the design process we pulled all kinds of strings and looked at how the effects impacted each other. We kept going until we hit on the perfect balance: the lumen package, the energy efficiency, the size and shape of the luminaire, the operating life time, and so on. One very important choice was to make the bottom of the Luma very flat (with no parts sticking out), so that it complies with the important G4 glare class, where upward lighting must be avoided.

A maximum of 200 LEDs with 40,000 lumen can be installed in the Luma 3. That number is required to replace a luminaire with a 400 Watt SON-T lamp. If a lower lighting level is desired, you can use fewer LEDs or the same number of LEDs at a lower current. This can be done in steps of 20 LEDs every time.

Indal introduces two Luma’s. The Luma 3, at 1 meter length, is the larger of the two and can be equipped with a minimum of 100 and a maximum of 200 LEDs. The Luma 2, at  80 centimetres length, can accommodate a minimum of 60 and a maximum of 120 LEDs. That fits in nicely with the maximum of 52 LEDs in the Stela Wide.

Thermal management

As everybody knows, LEDs can get very hot. That means that extra focus must be directed at the thermal management. The heat development takes place at the back of the LED. A careful choice of thermal resistance, for example, and clever positioning of the LEDs increase the cooling options. If the maximum number of LEDs is not necessary, the LEDs are positioned further away from each other. “We devised the optimal patterns for this. Nowadays we manufacture the PCBs for the LEDs ourselves in our factory in Emmen, so that gives us great flexibility.”

The luminaire housing was designed in such a way (it includes an aluminium temperature buffer) that the heat of the LEDs spreads evenly over the housing. Just like the Stela, the heat is discharged into the open air through the housing. This is called the COO-LED™ principle. To create enough capacity for the heat dissipation, the surface of the top of the luminaire is enlarged with slightly curved ribs. Both the luminaire housing and the ribs are optimally rounded and designed that water easily drains off.

The Luma is fully dust-proof and waterproof and complies with IP 66. Moreover, in closed position, the LED module is protected by an eXtra gasket (XIP).

L-tune: tuning customer’s needs…TRIPLE-C in the best manner

The Luma is equipped  equipped with programmable drivers. The amount of milli-amperes to drive the LEDs can be defined very accurately. Which lumen package do I need exactly? You can build and tune this in several ways. To do this, we developed a calculation tool (L-tune) that specifies the options in Luma depending on the customer’s wishes. With a low current level, you can achieve the highest energy savings and probably also the best Total Costs of Ownership – and it’s also good for the operating life time, of course.

But then you need more LEDs. If you use a higher current, you may achieve your technical lighting requirements with much fewer LEDs. That means that you could get the same result with the smaller Luma 2 instead of the Luma 3. That’s less energy-efficient, but if your investment budget is the deciding factor, it’s probably the best solution.”

“We assess every customer’s situation individually. This methodology fits seamlessly with our TRIPLE-C philosophy – leaving the choice to the customer. So the customer is free to choose the perfect balance between Comfort, Care and Costs.”

CONSTAFLUX

Luma instalada en Tolouse (Francia)

Another new novelty that Visser believes will be very popular among many road authorities is called CONSTAFLUX. This clever system has been made possible thanks to the use of the programmable driver.

Normally, the lumen output of a LED falls back during its life time from 100 to approximately 80%. A lighting design is usually based on the lowest value, in this case 80%. The other 20% of the initial period is therefore actually superfluous lighting and thus wastes energy.

“We approach it differently: we programme the driver based on that 80% as the technical lighting value. At the start, the driver produces less current and gradually increases the current during the operating life time, so that the amount of lumen remains constant. On balance, that means extra energy savings of 25 to 35% on top of the savings made by the Luma itself. “We believe that many customers will opt for CONSTAFLUX, not least because they are sure of recover their investment.”

Fit & Forget

With the Luma, the concept of Fit and Forget is now within reach. Wim Visser explains: “People tend to think in terms of standardised solutions, because lamps always had to be replaced regularly. But with the tuning that we now have, the customer can choose the solution that suits best. In your lighting calculations, you determine how much lumen and which lens-optic you need. Then you can calculate the options; if you want the LEDs to last for, say, 80,000 operational hours, without replacement. Then L-tune presents you with the option of more LEDs and less current, making the system extremely efficient, or the option of fewer LEDs and more current, which is less efficient. It’s entirely up to you which Luma you use, with how many LEDs and on which milli-amperage, and with or without a dimmer and CONSTAFLUX. And that’s exactly how we build the Luma, according to the customer’s specifications in our own factory.”

“When you follow the Fit and Forget philosophy, you are not buying a luminaire – you are buying a system for life. With today’s traffic routes, where the availability of the road is a vital factor and you want to minimise road lane closures for maintenance or replacement activities, there’s a growing need for Fit and Forget. The Luma is now finally making that possible.”

Following the success of the Stela for mostly residential areas and the T-line for tunnels, Indal introduces a  new LED luminaire for traffic routes, that can replace 250W and 400W High-Pressure Sodium lamps. This will enable savings on energy costs  and CO₂ emissions from 10 to 40%. Considering that these installations involve high wattages, this adds up considerably. LED is about to experience new levels of success.

Less lumens, the same lighting performance

The Luma features the popular REVOLED™ technology, that offers the same lighting performance on the road as the familiar High-Pressure Sodium lamps, but with fewer lumens – this combined with significant energy savings  from 10 to 40%. Moreover, with Luma, light spillage and light pollution is kept to an absolute minimum. The objective was to find a low current  and maximum energy saving alternative to the usual road lighting up to 400W to truly add something new to the current offer in the lighting industry. With Luma there is now an excellent LED alternative for traffic routes, such as motorways, inter urban main roads, ring roads and main roads.

A different approach than  residential area street lighting

With the design of the Luma a wide range of criteria  was kept in mind. First, a traffic route requires more light than in a residential area. Residential areas require 2,000 lumens per installation. The Luma can provide up to 40,000 lumens and can even replace the 400W High-Pressure Sodium lamps, which are used internationally. By placing a large group of LEDs close together, the size of the luminaire is kept to a minimum. And to prevent  thermal loss of light, an effective cooling system is integrated into the design.

In addition, Luma achieves adequate energy efficiency and requires no periodic lamp  replacement. All of these characteristics make Luma a lighting system that is truly innovative. Another important criteria in the international package of requirements is non-glare optics that satisfy the ME1 till  ME6 road  lighting standards, while at the same time preventing the  light distribution ‘drifting off’ towards the bank or the sky. Again the Luma meets these demands.

Customised light

An especially attractive use of the Luma is the option to programme the power supply   precisely. You can customise  the required light flux, desired life time expectancy and energy consumption precisely to your situation. As a result, you no longer talk about luminaires, but about lighting systems that can offer ‘customised light’.

People are inclined to think in terms of standardised solutions. But with the setting that Indal offers, the  operator can select the  ideal solution. During the lighting calculation, you determine the number of lumens you require and which lens-optic. Next, you can calculate what the options are if you want the LEDs to last 80,000 operational hours without replacement, for example. The calculation tool that Indal offers then gives you the option: more LEDs and less power, and therefore very energy efficient, or fewer LEDs and more power, and thus less energy efficient. With Luma, the road authority installs a system. Given the current traffic routes, where the availability of the road is a major consideration and road closures costs a great deal of money, with Luma, you save on the overall maintenance costs.

Some European cities have already started to test Luma in their traffic routes

Fit and forget

With the Luma, a large quantity of LEDs are placed close together (varying from 60 to 200 LEDs) on an  LED module with a flat glass cover. This makes it possible to carry out a  replacement of the LED module, for example, if you have opted for higher power  use with shorter service life times. However, the basic assumption is that the LEDs in the Luma will last up to 100,000 operational hours, which is the equivalent of 20 to 25 years. You just fit it and forget.

Considering the large number of LEDs on a fairly small surface, an effective cooling system is essential. The further the LEDs are spaced, the quicker they cool off.

For that reason a thickened layer of aluminium is applied, above the LEDs in the luminaire,  that dissipates  the heat. On top of the housing a sloping line of rounded ribs are incorporated, that provide rapid heat dissipation to the outside air and promotes the service life time and light output of Luma.

The Cargo Sheds No. 4 and No. 5-9 South Wharf represent the last (in situ) remaining link with the cargo and berthing facilities of the nineteenth century river port of Melbourne, originally extending to Queen’s Bridge, and is now the most eastern part of the port of Melbourne. The Sheds, and associated wharfing, illustrate the small scale methods of cargo-handling direct from ship to wharf, in the era of trans-shipment and before the introduction of roll-on roll-off and container shipment. They have been in use for cargo-handling for over 60 years.

They also represent an important transitional link between the period of smaller shallow draught trading vessels and the age of larger vessels involving greater droughts, tonnage and length.

Cargo Shed No.9 Wharf, built in 1884, is the oldest cargo shed in situ along the river within the Port of Melbourne. Whilst its fabric has been partially destroyed by fire, the remaining shed provides sufficient evidence to illustrate the style of construction including the unusual truss design, alignment with the river, and association with the once thriving maritime industry within close proximity of the city of Melbourne. It is a unique survivor of a once-common building practice in the transport industry.

Cargo Sheds No.4 and Nos 5-8 South Wharf between 1929-31 reflect the construction principles of the early twentieth centuries including roller shutter doors at regular intervals rather than sliding doors, flexible open floor plan enabling berths to be allocated as required, and ridge lantern lighting for security and lighting.

The access roads to sheds number 5-9 (south wharf road) displays evidence of bluestone cobbles, and contains some of the earliest macadamized roadway within the port of Melbourne.

The sheds and wharves are also closely associated with the heart of Melbourne’s ship building and marine engineering industry, carried out on the south bank of the river from the 1850′S. As the focal point for Melbourne’s commercial shipping trade, the Yarra River in the vicinity of Spencer Street Bridge was an important location for the repair, maintenance and construction of cargo vessels. It is significant that this area survives in close proximity to the commercial centre of the city of Melbourne.

The historical importance of the sheds and wharves is therefore enhanced by their location within an area that still retains its nineteenth century maritime character. The sheds themselves also make a significant contribution to the maritime precinct. Other elements include the Robur Tea House and Buchanan and Brock, engineering workshop, the Duke and Orr Dock, former Titan Wire Products factory, the amalgamated marine engineers building and the “Polly Woodside”.

CORVE from Indal and distributed by Masson for Light in Australia  was the lumunaire chosen by Architect, as it fulfilled the original luminaire brief of this project: luminaires with old look, reclaimed and industrial looking, like they have been there for 80.

Due to the Cargo shed having an old timber roof structure, there was a combination of custom rod suspensions and ceiling mounting required.

The roof structure had multiple ceiling angles and heights, So there was numerous site visits and design drawings required to meet the customers and sites requirements.

The new greenhouse complex of seed cultivation company Monsanto Vegetable Seeds in Bergschenhoek in the Netherlands, is fitted with Indal luminaires. With advice from Patron Agri Systems Group in De Lier, Monsanto chose Optipar. Patron is responsible for all climate, electrical and water-related issues in the project soon to be handed over.

Monsanto Vegetable Seeds has a subsidiary in Bergschenhoek, since it took over De Ruiter Seeds in 2008. The vegetable seed division focuses on innovations for improving the quality and output of vegetables. The company develops products that offer consumers new, healthy and delicious choices with unique nutritional values.

The Bergschenhoeklocation specialises in cultivation, production and sales of vegetable seeds such as tomatoes, cucumbers, aubergines, sweet peppers and melons. It is one of the absolute top cultivation companies worldwide. The expansion will further reinforce this position. The project contains 3.3 hectares divided into several cultivation and production departments.

Patron Agri Systems
For both Indal and Patron Agri Systems it is a prestigious project. Patron supplied and installed the computers, the electrical systems, water and lighting installations etc. for the new Monsanto greenhouses.

Patron Agri Systems Group was created in 2008 in the merger between Enthoven Elektra in De Lier, Elektro Limburg in Maasbree and Hoogendoorn Projects (formerly a division of Hoogendoorn Growth Management in Vlaardingen). ICT company AEM in Maasbree also joined the group in 2009. Bundling the expertise and experience of these installation companies created a complete provider with a leading position in horticulture, both in the Netherlands and abroad.

Monsanto uses strict safety requirements, which the installers had to meet, who worked at the new construction. The requirements are comparable to those in the petrochemical industry. For example the installers had to wear gloves, helmet, safety jacket and safety goggles while installing the lighting. The Optipar’s were installed from hydraulic platforms. Everything had been put down in writing and compliance was verified..”

Lighting plan

The lighting plan for the greenhouses was prepared by DLV Plant. The tender was based on this plan. Various luminaires of various brands were discussed. Indal’s Optiparoutstand as far as quality, simplicity of installation and maintenance were concerned. This is why Monsanto chose the Optipar. The service commitments also satisfied the customer’s requirements.

Patron Agri Systems and Indal drew up a tailor made lighting plan at a later stage as this  became necessary after the height of the cultivation was changed in a number of places.

Minimum failure
The lighting requirements for seed cultivation exceed those by flower and vegetable growers. The essence in those sectors is optimal production, which determines the margin. Seed cultivation has much stricter requirements and the interests are higher since the products are more expensive. Thus an important factor in opting for Indal was the minimum failure rate and the guarantees for this. Once the luminaires are installed and the product is growing underneath, it is best if you no longer need to access them. You can still do so, but it is inconvenient, due in part to the strict safety standards.

To protect the plants, you also want to prevent as little replacement and maintenance as possible.In total 926 luminaires were installed last summer.
