In recent years the major trend in lighting has been LED technology. The number of applications where LEDs are the most viable option is growing rapidly. Lighting control has been available for decades, but a real breakthrough will be realised through advanced control of LEDs. The use of lighting control is predicted to grow by nearly 20 % annually. This is due to the decision makers’ genuine interest in energy efficiency and the actual needs of the user. Intelligent lighting control is the key to achieving remarkable energy savings and optimal lighting environments.
The steady increase in the use of DALI is due largely to its flexibility. You can use DALI for a range of applications from a single luminaire installation, right through to controlling an entire building’s lighting system, with full integration into a building management system.
For the end user DALI control provides almost limitless freedom for modifications, ease of use and real time system monitoring.
DALI control enables buildings to obtain the highest levels of energy efficiency classifications (LEED, Breeam).
Beyond providing appropriate lighting conditions and energy efficiency, the next step in advanced lighting is expected to be human-centric lighting, which aims to improve people’s wellbeing, comfort, productivity and health. Research indicates that productivity gains of up to 7.7 % are possible in blue collar working environments (1 . What people require from lighting is endlessly diverse and constantly changing, guaranteeing longterm demand for flexible lighting control systems.
Our scalable end-to-end solutions meet this demand, giving freedom to our customers to get the best out of lighting.

Helvar and Sweco have a long history of fruitful cooperation: Helvar lighting systems have been delivered to many a project designed by Sweco throughout the years. The cooperation is effortless and the relations between the companies and the people are excellent.
Reasons to choose Helvar included flexible, reliable lighting systems with great variety and high energy efficiency from a trustworthy partner. The lighting system now covers all areas in the entire office. This means there are thousands of
Helvar DALI -units, LED-drivers and other equipment in

STOP THE PRINTING PRESS
”The tower used to be a newspaper house. Now, the floors and the ceiling of the printing room have been cracked open to allow for a large light opening, to create a full-height ”living room” in the heart of the building”, says Lars Dahlborg, who designed the lighting in the building. A huge, snakelike

Wherever daylight is available, it is used to the fullest. Helvar Multisensors 312 harvest daylight adjustment and presence detecting for create optimal light levels in the workspaces.
Thanks to these advanced features, the building only uses
5,4W/m 2 of electricity – making it incredibly energy efficient compared to any average building. With the carefully planned lighting and creative luminaires the entire building is united by light. Square-shaped microplasma sheets in the ceiling connect with the desk lights and so on. The cool 3,000 Kelvin colour tone is trendy and ”crispy”. Everywhere, the DALI systems run predetermined lighting scenes for different purposes – but of course, allowing for manual adjustments.

Estonia, Latvia, Lithuania, Russia, Bulgaria, the Czech
Republic, Slovakia and Poland. Sweco employs about 9 000 people and has net sales of appr. 8.8 BSEK. Currently, Sweco has projects underway in some 80 countries worldwide.
Sweco is dedicated to sustainability in engineering and design, enabling the clients to carry out their projects not only with high quality and good economy, but also with the best possible conditions for sustainable development.
Sweco’s use of the concept of sustainability derives from the
UN report “Our Common Future” from 1987, also known as the “Brundtland Report”. It defines sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” The results of this work are cleaner air and purer water, more efficient energy usage, better living and working environments, smarter transport solutions and industries that are profitable and environmentally sound.

Architect Johannes Tüll says he wishes to create a dialogue between the building and its surroundings. Tüll has some more finishing touches in mind. He’s already put in a tickling detail, playing with the lights on the vertical window row on the facade of the building: the lights shifting in different colours create yet another eye-catcher in this intriguing office tower.
Sweconites are proud of their new headquarters. And for a good reason: the building was awarded with the Sweden
Green Building Council’s Environmental Award for sustainable reconstruction work. Even Helvar’s sales manager
Hans-Göran Johansson muses: ”This building is architecturally impressive, and the lighting brings added elements to the common areas. We are glad to have been a part in the lighting of the new Sweco headquarters. The result is really great – and reached all the goals set in the beginning of the project.” He casts a glimpse at the play of lights. They seem to be telling the whole neighbourhood that Sweco has landed.

I have heard these two questions repeatedly in recent years.
It’s actually impossible to answer them without asking a few more questions. ‘What do you mean by LED? What do you want to compare LED with? Where do you wish to use LED?’
Often, when people talk of LEDs, they mean LED luminaires which, in addition to the light-emitting diodes, also include optics, mechanical parts and a driver. The driver converts the alternating mains current into a direct current which the
LED can use.
Lighting should be implemented according to the surroundings and the users’ requirements. It is the lighting designer’s duty to find the technical solution which meets these requirements in an energy-efficient way. More and more often, this solution includes controllable LED luminaires.

LED-based lighting technology will provide an opportunity to cut the consumption of energy effectively, without upsetting voters too much.
LED ADVANTAGES
If we compare LED to other technologies, each of which offers the best performance in its particular area, some of the frequently mentioned advantages of LED will no longer apply
(long life, fire safety, flicker-free light, contains no mercury, cold tolerance, free of UV and IR light).
The efficiency of LEDs is improving. Year after year—or actually month after month—they produce more light in proportion to the power they use. What part does the driver play in the energy efficiency of LED lighting? The word ‘driver’ is rather informative in this respect. The driver is used to control the production of light in an LED luminaire. In principle,
LEDs are fed by either constant-voltage or constant-current drivers. In LED luminaires, the prevailing practice is to use a constant-current driver. It gives better energy efficiency.
For a long time, one real advantage of LED has been its small size. It has made possible new shapes in luminaires as well as more precise optics designs, particularly in different spotlighting solutions. This combined with RGB solutions has given rise to new kinds of lighting. However, it has brought very little to the field of large-scale general lighting. By far the most important advantage of LED technology, energy efficiency, is finally beginning to become a reality in nearly all lighting applications. As there will be no efficient, simple and clean enough energy technologies available in the foreseeable future, energy saving will be an even more important driving force in the lighting business as well. For politicians, too,
LED DRIVERS
Some LED drivers are manufactured so as to meet the Safety
Extra Low Voltage (or SELV) specifications and some are not.
A SELV-compliant driver makes it easier to design a luminaire as far as safety is concerned and may even improve the system’s overall efficiency as it becomes easier to use part of the luminaire body as a heat sink.
9
However, as LEDs make their way into general lighting, the trend will probably be towards lower current levels which make it possible to improve the efficiency of LEDs. The DC voltage limitation of a SELV system is 120 volts. The limit is easily reached when we want to have more power at low
HELVAR NEWS | ISSUE 16

“
general lighting is concerned. The analogue 1-10 V control which is still being used with fluorescent lighting is steadily losing popularity.
LED CONTROL VS. FLUORECENT CONTROL
LED control brings more savings compared to control of fluocurrent levels. Given the additional fact that losses in a SELV driver are slightly bigger than those of a non-SELV driver, the non-SELV alternative may gain popularity in the future. rescent lamps. This is especially the case at low light levels
(0–20 %), where the energy savings become significantly smaller as the glow starters in fluorescent lamps need their standby current anyway. With LEDs, savings are achieved linearly down to the zero level. Furthermore, the lighting control function prolongs the lifetime of a LED luminaire. Both
LEDs themselves and the electronic components in the drivers benefit from lower temperatures.
However, this is not something that an end user or lighting designer should give much thought to. What is important is not the current and voltage values but the energy efficiency of the system and the quality of lighting. It is up to the luminaire and component manufacturers to provide sufficient data for designers. If the light distribution and service life data of a product are not easily available, it is better to forget the product.
One challenge in LED control is the flicker which occurs at a rate of a few hundred hertz, caused by the commonly used pulse width modulation technique. In Russia, the legislator has already set limit values for LED flicker. It is likely that in the near future this issue will be raised in other parts of
Europe as well. Manufacturers have already suggested some solutions.
From an energy consumption standpoint, it is essential that the lighting control is available. Even the best LED luminaire consumes more energy while being on (when not needed) than the worst incandescent lamp which has been automatically switched off. The digital DALI system has gained popularity in the field of LED control, at least as far as large-scale
So, there is no straightforward answer to the question of whether you should start using LEDs. It is always a good idea to reserve enough time and resources to chart your

specific needs. It is the first step in the process of designing your lighting system. Other steps in this process include energy comparisons, lighting control plans, cost comparisons and preparing instructions for the maintenance of the system.
More and more often this process will lead you to choose a controllable LED lighting system. However, never choose a technology or solution without first going through the planning process.
A DALI LED driver provides almost limitless possibilities for lighting control. In most applications, a controllable driver and lighting solution enable bigger energy savings than any other hardware choice.
LISTED BY HELVAR’S LED EXPERT, AKU MOILANEN.
Efficacy is a parameter that varies according to the load. It is therefore important to choose the right driver for the load. In controllable devices, another important parameter related to efficacy is the power consumption in standby state.
A long lifetime of the driver is important for the entire lighting system. At Helvar, the lifetime is determined by the maximum temperature at maximum load. When comparing the expected lifetimes of drivers, you should take into consideration the conditions in which the lifetimes are determined.
The most important of these is the ambient temperature.
The high quality lighting control performance is an important feature. LED as a light source responds quickly to all changes in the load current. This property makes LED control a difficult challenge. No steps should occur when the light level changes; low levels in particular are challenging. In addition, the light should be stable at all light levels.

Important for minimising maintenance costs.

PICTURES Cafe Royal
The site of London’s Café Royal has recently undergone radical restoration and redevelopment under the direction of David Chipperfield Architects. The development is part of Crown Estates wider remodelling of Regent’s Streets southern end. The reopened site now has 159 guestrooms and a selection of bars and restaurants, all of which incorporate
Helvar lighting controls. This huge hotel (25000m 2 floor space in total) works with a variety of control gear and lighting scenes to suit different environments and lighting requirements.
The hotel began life in 1865 and by the end of the 19th century it had become the epicentre of London’s exclusive social-set, with a reputation for having one of the finest wine cellars in the city. Over the years, Café Royal has hosted international celebrities, from royalty such as Edward VIII, George VI and Diana Princess of Wales, to some of the biggest rock stars of all time, such as Mick Jagger and Lou Reed.
The lighting control element of the project is split into two sections and each presented its own set of challenges.
The first section looks after the public areas, namely the restaurant, bar and the lobby area. The second covers the bedrooms and provides adaptable lighting presets for day and night.

BE OUR GUEST
All 159 guest suites are fitted out with eleven lighting control channels and contain a combination of LED and halogen light sources. Due to the historic nature of the hotel, Café Royal did not want modern control elements to be visible on the user interface. A special design was created to fit in with the traditionally decorated suites. With high ceilings, wood paneling and gold touches, the decor needed to remain the focus of the room and not be overshadowed by the technology.
“
To meet the aesthetic needs, custom DIN Rail arrangements were supplied with Helvar dimming and switching modules mounted onto them. These were prewired and ready for installation inside an enclosure, which also houses the guestroom distribution board, heating and air conditioning controls, and room management system.
In contrast to the grand lighting design the client specified that the system’s user interface should be simple and user friendly. Being a hotel, guests would need to be able to successfully operate the controls without any instruction.
Pre-set scenes were a major consideration in the original specification to give a wow factor through effective scene setting and design. Helvar created a custom version of its
100 DIGIDIM Rotary Module which impressed the client and ultimately won the order of the guestrooms. To disguise the technology amongst the traditional décor of the hotel, the modules have been mounted behind a custom built
Italian antique bronze face-plate, made by B&B Italia.
The Helvar DIGIDIM system in each guest room interfaces with the room management system and a ‘Welcome’ scene can be activated when a guest checks in and the lights are switched off when the guest checks out. This element adds to the seamless service offered by the hotel but also presents saving energy benefits by reducing wasted light in the building.
14 HELVAR NEWS | ISSUE 16

WHAT USEE IS WHAT YOU GET
Staff at the hotel need full access to the public lighting and this was required from day one of the handover. Helvar’s uSee interface has been accessed via an iPad to offer the staff a solution that allows for both central control over the lighting, and added benefit of mobile control so scenes can be deployed and altered locally.
The uSee software automatically generates HTML pages of the system which can now be viewed on any device with a web browser. Café Royal staff now enjoy access to all preprogrammed lighting scenes in each area and have the ability to control each lighting channel using the sliders created by the uSee program. This gives a great deal of control back to the staff, allowing them to take charge of the lighting without needing to bring the programmers back for assistance.
The lighting control in the pool and gym area of the spa is also a Helvar system. The colour changing setup is controlled by
100 drivers, which connect to 920 Routers. Red tones have been set for the sauna with a contrasting cool-blue in the pool area. The lighting design in these spaces is a big factor in creating atmosphere and the system skillfully balances the demands of the brief – creating spaces where lighting adds to the prestige of the building, not distracting from it.
This extensive project demonstrates how proper lighting control can provide both energy saving benefits and how modern technology can be intertwined into a historic building without disrupting the design or appearance.
Throughout this project the Helvar system serves the building and helps to showcase it outstanding design and frames its beauty.

Helvar was chosen to design the lighting control systems in the massive project. It is no coincidence: known as an ecosustainable forerunner, Helvar’s philosophy is in complete harmony with the ambitious project.
HOME OF SCIENCE, OPEN FOR EVERYONE
The Lecco campus gives a new lease of life to a part of the city that had fallen into disuse. New structures have been added to the former hospital building, creating an open university that is both visually and practically in sync with the area.
Architect Paolo Bodega created a transparent and “open” building seamlessly interacting with the city. This centre of science in the heart of the urban environment is shared by the students and locals alike, as the city people are welcome to use parts of the campus or to just stop by in the wi-fi garden, connecting with the rest of the world.
17 HELVAR NEWS | ISSUE 16

Bodega chose materials that symbolise of the area: aluminium, steel and glass. Light, luminous and predominantly white, the campus stands out against the city skyline. There is a strong sense of continuity between the indoor and outdoor areas, connected by large windows.
The Campus will be completed by 2015 with the building of a new university residence and a laboratory complex, which will be shared with the scientific teams of Milan University.
“
VISUALLY STRIKING, ENVIRONMENTALLY
SUSTAINABLE
The designers were very clear in their focus on sustainable construction technologies and energy efficiency of the systems and installations. Principal Mr. Azzone says: ”This new campus is experimenting with a model of a future university. It serves as an example for the entire country: synergy between technology and art, between research and enterprise, innovating and hard work”.
A prefabricated system was used for construction allowing for rapid building and a clean construction site. Renewable local energy resources – water, sun and air – offer clean energy and limit emissions of carbon dioxide, thus earning the building energy classification B.
A modular system of heat pumps using underground water is used for air conditioning. There are also solar panels and wind thermal panels on the roof. “It is a green university, built with mainly recyclable materials. In 40 years’ time, the structure could be dismantled and reused as part of a renovation project,” says Paolo Bodega.
INTELLIGENT LIGHTING CONTROL WITH
DALI
The technologies chosen to improve energy performance include the Helvar DALI lighting control system. The DALI system has been designed to control the areas with the most natural light, since they look out onto the courtyard and have large picture windows. The lighting system in the classrooms, offices and halls uses daylight harvesting to optimise the use of natural light. In the classrooms, the scene setting is also possible.
In the interior areas – such as the corridors – with less natural light and where the principal need is safety, lighting is managed with presence detection sensors. Mr. Gnecchi,
Spanning approximately 30,000 m 2 with 27 classrooms and almost 2,800 seats, the renovated campus is the flagship of the Lecco area.

an engineer from Elettromeccanica Galli, explains: ”We have worked with the Helvar staff to create a user-friendly, simple layout that is easy to manage and operate. Once the installation and programming is complete, the customer will be able to manage day-to-day use of the system independently”.
Light level is maintained at a constant 500 lx with the
Multisensor 312. The lighting system provides optimal energy efficiency and ideal lighting comfort. “All the luminaires of the university are controlled and it is possible to check the status of each luminaire by a central computer.
This allows constant monitoring on energy consumption by area and also monitors the emergency lighting system”,
Gnecchi continues.
Each floor is equipped with Helvar DIGIDIM routers.
Lighting in the classrooms is controlled with Multisensors, providing constant light functionality for daylight harvesting.
Commissioning and maintenance of the installed DALI luminaires (fluorescent 1x80W) is achieved through DALI router system. Each classroom has a push-button panel positioned near the lecturer’s desk for selecting different lighting scenes and controlling the blinds as needed.
Helvar’s experience in large-scale projects offered the best technical and programming skills while keeping the tight time schedules in the massive building project.
An outstanding result, in view of the size of the building complex.

Deltares is an independent institute for applied research in the field of water, subsurface and infrastructure. Deltares applies its advanced expertise worldwide to help people live safely and sustainably in delta areas, coastal zones and river basins. To encourage collaboration and knowledge exchange inside the organization, Deltares decided to revitalize its campus area in Delft, South-Holland.
ENABLING SUSTAINABILITY
The revitalization of the Deltares campus includes a new office building, a conference centre and new test facilities, all reflecting the mission of Deltares: enabling sustainable delta life. Deltares has applied its own Eco Dynamic
Design (EDD), which links the development of a site or infrastructure to the specifics of the location, generating positive effects in terms of ecological values, soil, water and air quality, possibilities for recreation, and options for future use and experience. The Deltares mission “Enabling Delta
Life” is realized by using the campus as a testing ground for innovative technology and concepts.
Delft-based Jeanne Dekkers Architectuur designed the new office and meeting buildings to fit into the environment and current buildings, keeping in mind the Eco Dynamic
Design principles of Deltares. The two buildings, Tetra and Pavilion, use mainly natural materials, such as wood, and natural, light colours in the decor. Tetra, the new

The Pavilion is a 280 m 2 wooden conference centre having flexible space for workshops, courses, brainstorming and meetings. The Pavilion areas are easily modified for various sizes of events, with partition walls and thanks to the very user friendly lighting control system from Helvar. From the touchscreens it is easy to control the lighting scenes for different occasions and to create functional and effective lighting for the changing needs of the building and its users.
COMPLETE INTEGRATION
Emergency lighting is an integral feature of the Helvar lighting control system, which improves system efficacy simplifies the maintenance of the building. Helvar’s user interface uSee manages scheduled emergency lighting tests throughout the year. The end user is kept up-to-date on the state of the emergency lighting by reports, that uSee automatically emails to the user.
The complete system, controlled via Helvar 910 and 920
Routers, is connected to the building management system with Tridium’s Niagara platform. Error messages from the lighting system, including possible faults in the emergency lighting, are clearly displayed in a central building management user interface. The Niagara Ax also provides the option of controlling the lighting system manually from the building management system.
In 2008, all the knowledge in the Netherlands relating to delta issues was grouped into one research institute; the
Deltares. Deltares has a unique combination of knowledge and experience in the field of water, soil and the subsurface.
It is the frontrunner in the development, distribution and application of knowledge for meeting the challenges in the physical planning, design and management of vulnerable deltas, coastal areas and river basins. Deltares works for and cooperates with Dutch government, provinces and water boards, international governments, knowledge institutes and market parties. The institute is located in two cities in the Netherlands, Delft and Utrecht, and has international branches around the world. Turnover in 2012 was
110 MEUR. The institute employs more than 800 people.
