LG CHEM OPENS AN OLED LIGHT SHOWROOM AND A NEW OFFICE

L

G Chem has recently opened an OLED light showroom in Seoul, Korea where LG Chem Headquarter is based in. The showroom is uniquely designed utilizing only the LG Chem OLED light panels, which gives life to the modern style and shows the characteristics and usefulness of the OLED light.

All of the LG Chem OLED light solutions and applications that were showcased in Lighting Fair Japan and Euroluce in Milan earlier this year are displayed in the showroom. Starting from simple rail system solution to OLED embedded furniture with transparent connecting solution, LG Chem aims to promote the possibility of day-to-day use of OLED light technology.

The showroom is mainly run by reservation, but walk-ins are also welcomed in the afternoon from 1:30 pm to 5:30 pm. For reservation, send a reservation request at reservation@lgchem.com. For any further detailed information about the showroom, please visit www.lgoledlight.com.

LG Chem has also opened a new office decorated and lit only with LG

Chem OLED light panels and luminaires on the 3rd floor of the same building with the showroom.

The new LG Chem OLED light office suggests many possibilities in using OLED light panels and solutions as office lighting and residential lighting.

According to ISO 8995-1:2002(E) which is an international standard for lighting of indoor work places, for writing, typing and reading, the average flux should be over 500 lx.

Also, the same standard applies for conferences and meetings. LG Chem OLED light office fits perfectly into the category with 550 lux in average in the working area.

For the main working office area, LG Chem has installed 8 rails, about 50 cm down from the ceiling, making them about 2.4 meters high. Each rail has ten 320x110mm OLED light rail modules attached to it generating great light uniformity with warm color temperature of 3,000K. For the lounge area, LG Chem has installed rail lighting and furniture embedded lighting. Rotating type OLED light rail module has been installed in the area for more exciting and fun design perspective of OLEDs. Also, OLEDs were embed-

ded in the wooden shelf lighting the catering table. LG Chem OLED light panels were a great fit for wooden shelf lighting for its thinness and lack of heat they generate, eliminating any fire hazard even without any heat sink.

For the conference room, LG Chem has utilized the largest in the portfolio, 320x320mm OLED light panels in check pattern, adding a hint of structural aesthetics while keeping the functional property and giving a more spacious impression of the room.

A mobile office is designed with 320x320mm OLED light pendants which also function as task lighting.

The OLED panels generate comfortable and relaxing atmosphere while giving a modern look to the office.

The office is about 170 square meters with different OLED applications in different areas.

Also, the bathrooms in the building were re-decorated with LG Chem OLED lights. LG Chem has utilized the OLED light panels’ unique characteristic which is a mirror effect to harmonize a mirror and a lighting fixture. Without the OCF film laminated on the top layer of the

panels, they are reflective chromefinished. By embedding the LG Chem OLED light panels into a mirror, LG Chem has created a new solution for bathroom lighting.

With minimal glare and high CRI characteristics, the mirror itself can be a lighting fixture which performs outstanding color reproduction range which gives the users maximum comfort in using a mirror in the bathroom. Also, since the mirror can be a lighting fixture itself, there is less need for other light sources to be on the ceiling which can result in cost reduction and space creation.

About LG Chem LG Chem, located in Seoul, South Korea, is an OLED light panel manufacturer which provides OLED light panels in a variety of shapes and sizes. Ten different models are available with two different color temperatures, which deliver high color rendering levels (CRI>90) as well as achieving high luminance, high efficacy and long lifespan.

Emergency Backup Module GL-EM01F for LED Panel Lights and Troffer Lights

G

lacial Light has announced an emergency backup module for its PL0606 & PL0312 ceiling panel lights and an emergency light version of its TL0606 troffer light. The GL-EM01F emergency backup module installs directly on the PL0606 and PL0312 panel lights and powers the emergency light version of the TL0606 troffer light, providing 90 minutes or more of constant-current power to keep these LED luminaires running in case of building power loss.

Rather than replacing existing drivers,

the GL-EM01F installs in addition to the existing LED driver and backs it up when power goes out. This allows these panel lights and troffer lights to dual function as regular and emergency lighting. Instead of buying both regular and emergency lighting, the GL-EM01F allows building owners to design lighting that works in both regular and emergency use case scenarios.

The GL-EM01F has a 3,000 mAh Lithium Iron-Phosphate (LiFePO4) battery that provides 90 minutes of backup power to the LED luminaires, allowing contractors to fulfill NFPA,

A new star has risen: first edition of C-star comes to a successful end

M

ay 15 saw the closing day of the inaugural edition of C-star, Shanghai's International Trade Fair for Solutions and Trends all about Retail. On May 13-15 retail professionals from all around the world came to the Shanghai New International Expo Centre (SNIEC) to see the latest retail technologies and trends for the Chinese market at C-star.

China's most international retail show Being the official satellite show of EuroShop - the world's No. 1 retail trade fair - C-star started as an ambitious project. Now after three show days, Messe Düsseldorf (Shanghai) Co. Ltd., the organizer of C-star, is proud to announce that the show was a phenomenal success.

The first edition of C-star featured an exceptionally high degree of professionalism - both exhibitorand visitor-wise. On a net exhibition space of 5000 square meters, C-star

featured 162 exhibitors from 23 countries, among them industry leaders such as Sibu Design, Schlegel Concept, Interstore, Ezidone, Changhong Decorations, Octanorm System, LS Lighting, Nedap, Bizerba China, Mettler Toledo and many more. C-star also saw an exceptionally high degree of internationalism, with nearly 50% of its exhibitors having their headquarters overseas. This makes C-star the most international retail trade fair in China and emphasizes the show's significance to leading retailers from abroad.

Visitor-wise C-star also surpassed everyone's general expectations.

Despite being held for the first time, an astonishing number of 5721 visitors from 59 countries and regions came to visit the show during the last three days, with 18% coming from overseas. Most international trade visitors came from

22 | September-October 2015 | Light Express

the USA, Japan, Hong Kong, Australia, India, Russia and Canada.

This further fosters C-star's status of being China's most international retail show.

C-star is organized by Messe Düsseldorf (Shanghai) Co. Ltd. and officially supported by the EHI Retail Institute, which is also the official supporter of EuroShop, C-star's mother show.

"The number of shopping malls in China is set to double over the next years and Shanghai is the top retail spot in China, setting the benchmark for the country's retail business. It only makes sense that we came here to start C-star. We have brought our expertise from Düsseldorf to Shanghai and everyone believes in the potential and the future growth of C-star!", says Mr. Hans Werner Reinhard, Managing Director of Messe Düsseldorf GmbH and

Chairman of Messe Düsseldorf China Ltd. Also, Mr. Michael Gerling, CEO of the EHI Retail Institute added: "China will soon become the world's largest retail market, so it was the right time and the right decision to start C-star now!".

High acclaim from all participants The show also saw many companies, who have been EuroShop exhibitors for many years: "When Cstar was launched at last year's EuroShop we were very excited to exhibit in China for the first time. We have been on board with C-star from the very beginning and we want to develop the show together with Messe Düsseldorf. You will definitely also see us next year at Cstar!", said Mike Boeffert, Managing Director of Schlegel (Ningbo) Co., Ltd. In general, C-star exhibitors were excited about the high quality of the

show's trade visitors. Mr. Wang Yue, Director of Changhong Decorations mentioned that "it's very fascinating to see the never ending visitor flow in the hall. We also had many potential clients visiting our booth in the past days and are more than satisfied to be here at C-star".

However, C-star is much more than a trade show as it featured an extensive supporting program. On May 12, one day prior to the show, C-star's supporting program kicked off with the C-star Retail Tour. This full day guided tour introduced Shanghai's most exciting shopping destinations to international retailers to give them exclusive insights into Shanghai's retail market and also help them to better understand the needs and requirements of Chinese customers.

During the first two show days the C-star Retail Conference, the highlight of the show's supporting program, took place in the Kerry Hotel Pudong, right next to the fairground. There, leading industry professionals came together for two days to discuss how retailers can turn their physical stores into preferred shopping destinations again, despite rising e-commerce and online shopping. The conference featured numerous keynote speakers from leading international and Chinese retailers such as METRO, Walmart or Yi-Hao-Dian. This gave retailers the unique chance to expand not only their knowledge but also their business circle. Mr. Lutz Bethge, President of the Montblanc Foundation and speaker at the C-star Retail Conference noted that "C-star had covered an exceptionally wide range of retail categories! Personally speaking, I really liked the combination of having more than 160 exhibitors here at a trade show and also holding a conference at the same time, where leading industry peers are speaking about the latest offline and online retail trends".

During the whole show time, C-star also featured the "Designer Village", a special exhibition area where international renowned retail design agencies presented their latest innovations for the Chinese market.

The concept behind the C-star Designer Village is to address the rising demands of Chinese customers regarding their shopping experience, as sophisticated shop designs and retail solutions are becoming increasingly important in China's retail industry. The fact that Cstar is the only retail show in China with a designated design area makes it one of its kind. Both visitors and exhibitors of C-star exhibitors were delighted to see the show's sophisticated and advanced booth designs. As Ms. Elke Moebius, Project Director of C-star's mother show EuroShop, noted: "We have not only seen 162 exhibitors from 23 countries but also a very high level of stand constructions and advanced booth designs - indeed not bad for an inaugural trade show in China".

start and we are very confident that the show will further develop and become the leading retail show in China", noted Mr. Bartkus, General Manager of Messe D端sseldorf (Shanghai) Co., Ltd., adding that "this is only the start".

In the meantime professional retailers can already get prepared for next year's highlights. On February 23-25 EuroCIS 2016, the retail technology spinoff of EuroShop, will kick off at D端sseldorf/ Germany and serve as the perfect warm up for C-star 2016.

A new star - C-star - has risen in China. What started as an ambitious

project eventually wrote a new success story by becoming China's most international retail show.

Missed the first chapter of C-star's success story? No problem! Join us next year in Shanghai on our promising journey! See you next year for a another exciting edition of C-star! Be part of it!

The New House: Building an Energy-Efficient House

T

here is no one template for an energy-efficient house. The needs depend on where in the world the house is located. The requirements for a temperate climate, with wide swings in temperature throughout the year, are very different from those for a hot dry climate, which may cool sharply at night, or a hot humid climate, which has very little temperature change from day to night.

That said, one thing remains the same all over for energy efficiency: siting of the house. The goal is to

maximize the Sun's heating effect in the winter months and to minimize it during the summer. To do this the house should be rectangular but as compact as possible. The longest wall of the house should be full of windows and facing the equator; in the Northern Hemisphere this wall would face south, and in the Southern Hemisphere the orientation would be reversed. Closer to the equator, the number and size of windows will be reduced.

Another factor to consider in choosing a site for a house is wind.

28 | September-October 2015 | Light Express

In cool and temperate climates the wind can significantly affect energy efficiency. To counteract this, hills may provide protection, and trees can be used as windbreaks. In hot climates the wind is an important cooling factor. Houses should be positioned to take maximum advantage of breezes, while construction features and trees may be used to channel them into the house.

Once the house is positioned on the lot, the next consideration is the structure of the house. Builders refer

to the actual structure of a house as the “building envelope.� The walls, roof, windows, and doors are what separate indoors from outdoors and control the flow of energy into and out of the house. Different climates require different design strategies and different materials. Another consideration is the typical material for a region, and what would be a good option for energy efficiency.

In addition, most people will want a house that fits the style of the region they live in. All these factors must mesh with the energy-efficiency requirements.

In addition to RBW being a Silicon Valley favorite, prominent design firms like Rockwell Group, Meyer Davis, and Yabu Pushelberg are installing its fixtures in upscale residential towers, hotels and restaurants. A range of international retailers, including the Conran Shop based in the Britain, is also ramping up sales abroad.

“Their pieces are beautiful and have this attention to detail and craftsmanship that you don’t get with a lot of major manufacturers,” said Denise Cherry, a principal of the San Francisco interior design firm Studio O+A, which conceived the design for the offices of Uber, Yelp and Zazzle.

hen three wide-eyed graduates of Rhode Island School of Design introduced a rough-and-ready lighting and furniture collection in 2008, it would have been easy to write them off as attention-seeking pranksters. Their Excel floor lamp — named after the popular software program — looked as though it were cobbled together from old broom handles, like a D.I.Y. sculpture.

And then there was their firm’s name, which bordered on obnoxious: Rich Brilliant Willing, with the preppy-sounding monogram RBW. Seven years later, the former

classmates have proved they possess not only staying power, but enough talent to fuel rapid growth.

The firm’s influence is arguably nowhere more visible than in the offices of Silicon Valley start-ups, where RBW lights have become de rigueur. The headquarters of Uber, Yelp, Fitbit, Beats, Zazzle and Nest, for instance, all glow from the signature lamps.

The firm’s moniker is even forgivable once you realize it is merely a play on their names: Theo Richardson, 32; Charles Brill, 31; and Alex Williams, 32.

“When we started, we had a drill press and a certain tongue-in-cheek flavor and attitude,” Mr. Brill said after

offering a tour of the firm’s new Flatiron district showroom, a Manhattan outpost for the Brooklynbased operation.

Since then, Mr. Richardson added: “We’ve refined our eye, along with the skills and systems necessary to create a polished product. We take some cues from minimalism, but we’re not making products that are devoid of character; they’re expressive, warm and simple.”

Their latest products include the Crisp, a puck-shaped cast-glass ceiling lamp with a surface reminiscent of a rippled potato chip (an additional corrugated brass reflector is an option), and Queue, a modular linear pendant lamp with a stepped

“But they also have that extra level of innovation, technology and sustainability,” she noted, which makes the products a natural fit for

tech companies.

Since 2012, RBW has exclusively used LEDs in its new lights (its older halogen models are in the process of being redesigned). And it puts an emphasis on making the technology easy to use.

But just because the company is working with the latest technology, that does not mean its designs are techie. Quite the contrary. RBW products maintain the soul of sculptural, incandescent fixtures with a hint of America’s industrial past, using handsome, time-tested materials such as handblown glass, perforated metal, and solid oak and walnut.

“What I like, and what the tech companies like, is the softness of their fixtures,” said Lucas Martin, a senior designer at Rapt Studio in San Francisco. “They almost look like they’re made by hand,” he added, in a sea of “cold, commercial LED fixtures.”

“I like that they’re able to create energy-efficient fixtures that don’t remind you of those remedial shoes people wear when they’re trying to be healthy,” Mr. Rockwell said.

“There’s also something about their energy and can-do attitude.”

Indeed, when you talk with the partners, they come off as conscientious hard workers, willing to do just about anything to please their customers. But they also periodically light up with moments of unreserved ambition.

“We’re just trying to do one thing really, really well,” Mr. Richardson said. “The point of our fixtures is not that we love LEDs or technology. It’s just that we offer something better.”

As the lead designer for Fitbit’s offices, Mr. Martin used RBW’s Radient sconces, which resemble floating circles of wood with concealed LEDs that illuminate the wall behind, to recreate the fitness company’s logo behind its reception desk.

If there is a handmade quality to RBW’s fixtures, it is because the firm’s team of 14 people assembles every lamp by hand using custom parts. The firm had tried licensing its products to manufacturers, as most lighting designers do, but found it more profitable to keep the manufacturing in-house.

Lighting the Future with Energy Efficiency LED LIGHTING OPERATION AND BENEFITS

L

ight emitting diodes, commonly called LEDs, are becoming more and more widespread in all uses from small flashlights to laptops, cellular phones, and televisions. You may think they are a new invention but they have been in commercial use since the 1970s as replacements for incandescent and neon indicator lights on electronic equipment. It has only been recently that LED manufacturing has reached a point where LEDs can be used to replace conventional lighting such as incandescent and fluorescent bulbs.

Before we discuss the benefits of LEDs, let’s review how LEDs operate.

LEDs differ from conventional light sources in the manner in which they produce light. Incandescent lamps are composed of a tungsten filament surrounded by a glass bulb filled with an inert gas. The tungsten filament is heated by electric current until it glows and emits light. On the other hand, fluorescent lamps are composed of a glass tube coated in phosphor and a very small amount of mercury. An electric arc excites the mercury atoms, which emit ultraviolet (UV) radiation. When the UV rays strike the phosphor coating, they are converted and emitted as visible light.

An LED is essentially an electronic component referred to as a solid state device. When used in lighting, it is referred to as SSL (Solid State Lighting). It is composed of crystalline layers of semiconducting

materials to form what is called a p-n (positive- negative) junction. The one-directional travel of electrons and electron holes flow into the junction between the semiconducting materials and combine to release energy in the form of photons.

Depending on the semiconducting materials, the emitting light can be invisible or in the visible spectrum of radiation. Red LEDs are based on aluminum gallium arsenide (AlGaAs), blue LEDs are made from indium gallium nitride (InGaN) and green from aluminum gallium phosphide (AlGaP). The components are covered in an epoxy lens.

Since “white” light is necessary for most lighting applications and LED’s do not initially produce white light, a method of generating white light had to be developed.

The first method uses Red, Green and, Blue LEDs to form multiple LED chips sometimes referred to as an RGB-LED . By mixing multiple wavelengths of different LEDs, an approximation of “white” light is emitted. By the use of a controller, combinations of wavelength intensities can create a multitude of colors allowing the designer to adjust the white light to a specific color temperature. However, because of the use of three LEDs for each chip, this type of chip is often more expensive to manufacture.

The second method uses a single blue Indium-Gallium-Nitride (InGaN) LED with a yellow phosphor coating to create white light. This is the method that results in the more commonly seen “white LED”. The low cost and sufficient performance makes it the most widely used technology for general LED lighting today. The disadvantage is the

40 | September-October 2015 | Light Express

inability to dynamically change the character of the light and the fact that phosphor conversion reduces the efficiency of the device.

LEDs come in two different basic categories, low power and high power. Low power LEDs are typically 0.1 watt, low current (~20 milliamps) and low voltage (3.2 volts DC). This type is used as indicators

due to the small output of light, around 2 to 4 lumens. High power LEDs are manufactured in 1 to 3 watt packages, high current (350-1000 milliamps) and currently maximum 138 lumens per watt and are the type used for lighting. Compare this to a 100 watt incandescent bulb at 17 lumens per watt, a 32 watt T8 fluorescent at 85 to 95 lumens per watt, or a compact fluorescent at 48

to 60 lumens per watt.

Because the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are typically arranged in arrays to achieve the desired light (lumen) output. With some units, the LED array is an of the LED Module System made of the

LED modules, power supply and control interface modules. This allows for a building block approach to create a variety of lighting patterns. There are now commercial LED lamps that are designed to replace incandescent quartz halogen lamps such as MR and PAR and fluorescent T8 36w lamps in existing installations without the need to replace the fixture.

Light Express | September-October 2015 | 41

integral part of the luminaire/fixture, unlike an incandescent light source where you replace the bulb when it fails. There are several reasons why the LED array is part of the fixture.

The main reason is heat dissipation.

The fixture is designed in conjunction with the LED array to properly dissipate the heat generated by the many individual LED chips. LEDs lose their efficiency if allowed to heat up.

There has also been the introduction From learning about the operation of LEDs you probably have realized the various benefits of using LEDs for a lighting source. So, to help solidify your thoughts on LEDS, here are excerpts from two energy reports giving you some percentages of savings.

According to the ICT for Energy Efficiency report compiled by the Ad-Hoc Advisory Group (European Commission) composed of Information and Communications Technologies providers, industry associations, end-users including regional and city groups as well as leading academics: “Solid-state light sources, i.e. lightemitting diodes (LED) and organic light emitting diodes (OLED), may in the future outperform almost all other light sources in terms of efficiency and thus provide a saving potential of about 50% of the electrical energy used for lighting.

If the advanced LED technology is combined with intelligent light management systems, which will control the light output according to ambient lighting conditions or people’s presence, another 20% can be saved – in sum 70%.”

But it doesn’t end there with the tremendous energy efficiency of the LED’s.

There are also environmental aspects that need to be mentioned. The ability to direct the light from LED fixtures toward the desired area reduces light pollution. As well, LEDs do not contain mercury, lead, or glass.

In January of 2011, the DOE (US Department of Energy) released a report that targets the use of LED lighting in 12 specific product types

spread over three general categories: general illumination, outdoor lighting, and consumer electronic displays. For general illumination applications, four markets were analyzed: PAR, BR, and R-shaped; MR16; 2-foot by 2-foot troffer fixtures; and general service A-type.

For outdoor lighting, four markets were analyzed: roadway, parking, area and flood, and residential. DOE also analyzed four applications for consumer electronic displays: televisions, laptops, monitors, and mobile handsets.

The report indicates that converting to LED-based light sources could approach an estimated annual saving of 263 terawatt-hours. This is the equivalent of taking 21 million households off the power grid. The DOE SSL 2010 Multi-Year Program Plan predicts that commercial LED luminaire efficacy will increase 155% over the next decade to 219 lumens per watt (lm/W). Assuming that the LED replacements within each niche improve according to the DOE’s SSL 2010 Multi-Year Program Plan predictions for 2020, LED efficacy increases the total potential energy savings dramatically to 399 TWh. This equates to a forecasted primary energy savings of the total energy required to power nearly 32 million average U.S. households.

According to the DOE report, the advantages other than just energy savings include: longer operating life, reduced radiated heat, minimal light loss, dimmability and controllability, durability, enhanced performance at low temperatures, safety improvements, smaller package size, uniform illumination, mercury reduction, enhanced product appearance, improved color rendition, and lower lumen depreciation.

Now, let’s summarize the advantages of LEDs as well as the disadvantages.

ADVANTAGES OF LEDS EFFICIENCY: LEDs can produce more light per watt than incandescent and fluorescent bulbs. This is improving with every new generation of LEDs.

42 | September-October 2015 | Light Express

Light Express | September-October 2015 | 43

Color: LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs.

As well, with the use of RGB LEDs any desired color can be achieved during actual operation.

Cool light: In contrast to most light sources, LEDs radiate very little heat in the form of IR that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED. Size: LEDs can be very small (smaller than 2 mm) and are easily populated onto printed circuit boards. This allows for the design of very low profile luminaires/fixtures.

On/Off time: LEDs light up very quickly. LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.

Life time: LEDs can have a relatively long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. Fluorescent tubes typically are rated at about 10,000 to 15,000 hours and incandescent light bulbs at 1,000– 2,000 hours. Shock resistance: LEDs, being solid state components,

are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile. This makes LEDs an ideal light source where the fixture is subject to vibrations and jarring.

Focus: The solid package of the LED can be designed to focus its light.

Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.

Environmental: LEDs do not contain mercury, unlike fluorescent lamps.

Disadvantages of LEDs High initial price: LEDs are currently more expensive, price per lumen, on an initial capital cost basis, than most conventional lighting technologies.

Temperature dependence: LED performance largely depends on the ambient temperature of the operating environment. Adequate heat-sinking is required to maintain long life.

There is no doubt that the use of LEDs for lighting applications has the great potential to save energy and allow for new and inventive lighting methods. They will not replace traditional methods such as incandescent and fluorescent overnight but they are evolving into a strong contender.

Opening opportunities for building control ENERGY SAVINGS FALL FOUL OF LOOSE SPECIFICATIONS

C

ontributing to the success of many important buildings is a building-management system based on KNX open architecture.

Iain Gordon of KNX UK examines its capabilities.

Even though there are different ways in which a building and energy management system (BEMS) can be implemented. In its simplest form, it essentially comes down to the control of the energy within a building. There are of course many different types of BEMSs available from many different manufacturers and some of them even have an open architecture.

A KNX building control system is

not designed to replace or be used instead of a BEMS, but rather it can take over the field control — that is to say, the room or floor control of heating and ventilation. Once a KNX system is installed, it provides an infrastructure to which different elements of control can be added — for example, controls for lighting, blinds and shutters, security and so on.

This infrastructure provides a solid and stable platform for energy efficiency within a building so that lighting and heating can be switched on or off based on occupancy or office hours. Blinds or shutters can be closed automatically to preserve as much as possible of the heat

46 | September-October 2015 | Light Express

generated within the building.

Home automation and control systems such as Crestron or DALI have their own strengths. Crestron's lies in the audio-visual sector, and DALI is a lighting-control protocol that can function on its own. Neither need KNX, but both can be connected to KNX via a gateway and integrated within a building automation system — in the case of DALI, helping to maximise its functionality.

Quite the opposite of proprietary technology, a KNX open-architecture building-control system allows products from many different manufacturers to be connected together seamlessly on the same

network — without the need for special application programmes or drivers. Indeed, it is a worldwide open protocol and is approved as European Standard (CENELEC EN 50090 and CEN EN 13321-1); International Standard (ISO/IEC 14543-3); Chinese Standard (GB/T 20965) and US Standard (ANSI/ ASHRAE 135).

Multi-vendor KNX-approved products can be selected on a mixand-match basis of the best products in a class and with guaranteed future compatibility with other KNX approved products. The system is also very easy to extend at any later date as new bus lines can simply be added to the existing

network.

As well as lighting, heating or shutters/blinds, KNX products cover a vast range of other applications.

They include smart metering, energy management, security-monitoring systems and audio-visual control.

This level of versatility is not available with proprietary technology.

Illustrative of how KNX interfaces with a building energy management system is the Siemens Crystal building in London. At its heart is a Siemens Desigo building energy management system that controls the building to ensure it operates in the most energy-efficient manner.

Meeting-room chilled beams, trench heating, blinds and lighting are controlled using devices on a KNX network. A combination of occupancy and CO2 sensors in the meeting rooms put these areas at their ‘day’ setpoints only when a room is occupied.

All this capability can be controlled via room units, and occupants can use third-party touch screens in each meeting room. This total room automation solution balances energy efficiency with occupant comfort.

BMS, BEMS, control, KNX, open protocol In the Siemens Crystal building, KNX is teamed up with a Siemens Desigo

building energy management system.

The system enables the many renewable building services elements of The Crystal to be used at their most effective levels because it is compatible with a range of open protocols such as KNX. It also provides reporting features so the building-management team understand how energy is being used and keep energy use within required parameters.

Another example is the AVC Inspiration Centre in Evolis, Belgium.

Noteworthy from the energyconsumption and building-design points of view, it features a building automation system with all services integrated through KNX. These include a heat-pump system for the heating, ventilation system, solardependent control feature and convenient lighting functions.

With its fully glazed facades and bright, open-plan indoor areas, buildings of this type need to be able to adapt to changing weather conditions for maximum energy efficiency.

They must be able to find the right balance between heating from the Sun and daylight, together with

cooling and proper ventilation at any given time. Therefore, its HVAC equipment, indoor temperature, solar control system, safety and security functions as well as artificial lighting need to respond automatically to external influences.

Using KNX, the system integrator was able to meet all these criteria.

The standardised KNX installation bus links the entire HVAC system — including boiler, heat pump and airconditioning and ventilation equipment — with the rest of the building automation system. In this way heating and cooling in the building can be controlled highly efficiently throughout offices, meeting rooms, showroom, bar and a multi-purpose room.

The indoor climate can be controlled conveniently via mini touch panels. Lighting in the various rooms can be operated from multifunctional controllers. In areas where artificial lighting is needed only sporadically, motion sensors ensure energy-efficient lighting use.

Constant lighting control in the warehouse area using DALI with interface to KNX also promotes energy efficiency.

The building also uses smart meters that continuously monitor and

record the power consumed by heating, air conditioning and lighting systems, by coffee machines and by equipment in standby. Any necessary optimisation steps can then be taken.

The new campus at the American School of Dubai spans 92 900 m². It comprises six modern school buildings, sports and art facilities as well as outdoor areas. The school’s building services are controlled by an automated KNX-based system.

By choosing KNX, the building owner was able to meet criteria for high energy efficiency, ease of installation, flexible technology and low investment risk. All lighting on the campus is controlled automatically via KNX. Even in the classrooms, this reduces energy consumption by 45% compared to conventional solutions. Presence detectors are fitted, which only allow artificial lights to be switched on when there is insufficient daylight and there are still people in the building.

The climate conditions in the rooms are also controlled automatically using KNX room-temperature controllers. After school hours, motion sensors and the CCTV system are activated and alerts are automatically transmitted via a KNX GSM gateway to a security company.

Number of US People Buying LED Lighting Doubled in Last Two Years purchased an LED, however, there seems to be quite a bit of misinformation about the technology's qualities and characteristics.

The survey noted that in-store products and displays were the most important source of information for consumers. That means buyers need not only attractive packaging with the right information displayed in the right way, but also an attractive price point that involves instant utility rebates or everyday low prices. Only 18 percent of respondents said they go to their electric utility for information about light-bulb purchases.

T

wo-thirds of Americans have purchased LEDs for their homes, nearly double the figure from just two years ago.

The changing landscape of LED adoption is obvious not just in the prices on the store shelves, but also in shifting consumer perceptions, according to the seventh annual survey conducted by Osram Sylvania. More people were aware of the term "LED" than "halogen" or "CFL."

The survey shows how quickly the tide is turning, but also highlights the fact that CFLs continue to dominate in terms of market share -- they were the most purchased bulb in the past 12 months. By next year, however, that could change.

More than half of the people surveyed said they purchased a CFL in the past year, but LEDs were close

It’s not just for specific purchases like Christmas lights, either. Instead, consumers are buying solid-state lighting for general illumination in the home. Those who are making the switch from compact fluorescent lights and incandescents to LEDs are lured by the color of the bulb, low energy use and Energy Star approval.

behind at 41 percent. The survey was conducted in February, before major brands rolled out LED bulbs that are now cheaper than CFLs. But price is not the most important factor for consumers, the survey found. Most people are looking for brightness and longevity, areas in which LEDs often outperform CFLs. Among those who have not yet

The change could continue to come quickly, according to survey data. Consumers who have already purchased one LED will likely purchase another the next time they need a light, and those who are considering smart-home purchases are also more likely to buy LEDs than CFLs. One area where price topped the list of concerns was connected lighting.

In this domain, about two-thirds of consumers said that the price was the most important influence impacting their buying decisions. As prices have already started to come down in that market, functionality and lighting capability may soon become more important drivers.

While their contours may have caught your eye, what you should really pay attention to is their energysaving potential. Results vary slightly depending on design, but replacing the old lightbulbs in your house with CFLs dramatically reduces your energy consumption— ENERGYSTAR®-qualified CFLs use approximately 75% less energy than

traditional incandescents! Plus, CFLs can last up to 10 times as long.

While the initial cost may be higher, these bulbs pay for themselves in less than nine months, and continue to deliver energy savings long after.

The trick to getting the most out of your new CFLs is proper installation and maintenance. These bulbs are sensitive to extreme temperatures, so be sure to use them in open fixtures rather than enclosed or recessed ones, which reflect heat around the bulb and consequently reduce its lifespan. You'll also maximize your energy savings by keeping lights with CFLs on for at

least 15 minutes at a time, something to keep in mind before you flip that switch to the "on" position.

Since CFLs do contain small amounts of mercury it is important to properly recycle them after use, and to take special precautions in the event that one breaks. Find tips on cleanup and safe disposal.

Light-emitting diodes (LEDs) LED bulbs are a more recent development in the world of efficient lighting. These bulbs use only 20-25% of the amount of energy consumed by incandescents, and they last approximately 25 times as long. Due to more durable designs, LEDs can be used both indoors and outside, and are available in a range of colors for anyone looking to add a little extra flare to their space.

While incandescents and CFLs emit light in all directions simultaneously, LEDs emit light in one specific

direction. This enables them to be more efficient, but also means a little extra consideration has to go into how they are used or which particular LED bulb you buy. For example, you might not want to use an LED bulb in a table lamp, since the light will be directed straight toward the ceiling, unless you've purchased a bulb specifically designed to mimic the spherical light emission of CFLs. As with CFLs, heat management is the most critical factor in ensuring the life of your LEDs—higher operating temperatures mean faster degradation, so it's important to be sure to purchase bulbs that are compatible with your fixtures.

Picking the right bulb Since CFLs and LEDs use so much less energy than traditional incandescents, knowing which bulbs will suit your lighting needs may take a little time to figure out. To match the light intensity of the bulbs

you're replacing check the package of your new bulbs for lumens (an indicator of brightness), rather than watts (a measure of energy use).

Use the chart below to get started.

CFLs and LEDs also come in a variety of color temperatures, another thing to keep in mind when you're trying to decide which bulb is right for you. Color temperature is measured on the Kelvin scale, ranging between 2700K and 6500K. The lower the K value, the warmer the light (meaning it gives off a more yellow tone); the higher the K value, the cooler the light (giving off a more blue tone).

Dimmers and sensors Want to take your lighting efficiency overhaul to the next level? Consider installing some of these features throughout your home to further maximize your energy savings.

Dimmers: dimming switches enable greater control over indoor lighting, rather than simply turning a light on or off. Dimming a light reduces its

wattage and output, saving energy and increasing the lifespan of some lightbulbs. Check the packaging to make sure the lightbulbs you're using are compatible with the equipment you install.

Occupancy Sensors: these devices automatically turn lights on when someone enters a room, and turn them off again after a short period of inactivity—perfect for those of us who just can't seem to remember to flip the switch once we leave the room. Sensors come in two varieties, ultrasonic (which detect sound) and infrared (which detect heat and motion). Just be sure to place your sensors where they will detect activity in every part of the room.

The New House: A Model of Energy Efficiency USING LESS ENERGY

A

ll around the world, homes are one of the biggest sources of carbon dioxide (CO2) emissions. But as concerns about the environment and global warming have intersected with rising energy prices, more and more people want homes that use less energy. How can we build houses that are energy efficient?

There are many ways to make a new building energy efficient. Insulation can be added to exterior walls,

ceilings and attics, basements, around heating and cooling ducts, and in framed floors. Covers and dampers on vents to the outside or unheated or cooled areas (such as exhaust fans and attic entries) also help save energy. Energy-efficient windows, doors and appliances add to the energy savings.

Energy efficiency occurs in two ways. First, the house must be able to maintain a comfortable indoor temperature for the climate, using the least amount of energy possible.

And a building that loses less energy is a building that uses less energy.

Second, the appliances that run the house—the heating and cooling systems, lights, kitchen and other appliances—must be energy efficient. When both of these overall

approaches are maximized, the house will use less fossil fuels and electricity, thus reducing CO2 emissions.

systems to use for heating and cooling, insulation, windows, lighting, appliances and electronics, water, and waste disposal.

The simplest route to energy efficiency: start from scratch, by building a new house. A new house can easily incorporate some of the techniques from passive heating and cooling, along with building materials—old and new—and appliances that help minimize the use of electricity or fossil fuel. The construction of an energy-efficient home requires careful and detailed planning using what is called a “whole-house systems approach.”

The approach looks at the interaction between the home, the environment, and the people who live there, to determine the best

Building Standards to Save Energy Santa Monica Civic Center Parking Structure The Santa Monica Civic Center Parking Structure, in Santa Monica, California, was built to LEED standards. It runs on solar power, uses fluorescent lighting and reclaimed water for landscaping and toilets, and is built partly from recycled materials.

Some countries have created programs to indicate energy-efficient

appliances. In the United States, the Energy Star symbol can be found on a wide range of products, including building materials and appliances.

Around the world, countries, states, and cities have developed voluntary “green” building standards. In the United States there is a certification program called LEED (Leadership in Energy and Environmental Design), which has been created by the nonprofit U.S. Green Building Council. It rates all aspects of design, construction, and operation, mostly for large-scale construction, such as government buildings, schools, and commercial spaces.

The LEED system has been adopted in several countries, including India, Israel, and Canada. The Standards

and Industrial Research Institute of Malaysia has recommended green building standards for that country.

In the United States, the city of Boulder, Colorado, has developed its own elaborate point system for energy-efficient building. Architectural designs will not be approved unless they earn a certain number of points, for such elements as insulation, precast concrete foundations, planting of shade trees, and energy-efficient windows. The Boulder program also requires that houses be disassembled rather than torn down and that at least 65% of those materials be recycled.

energy efficient. In the United States, the Environmental Protection Agency created the “Energy Star” program in 1992 for this purpose. More recently, the agency has designated Energy Star buildings as well. There are other nonprofit agencies that promote different aspects of energy efficiency around the world. One example is the Alliance to Save Energy, which is based in the United States but supports programs to increase energy efficiency around the world, in places such as China and Eastern Europe.

LED Startup Bridgelux Acquired by China Electronics Corp. ingly competitive LED market and compete globally on stronger footing. “This was a transaction that we have designed Bridgelux to be able to enter into,” said Bridgelux CEO Brad Bullington.

Bridgelux already has strategic partnerships with other companies connected to CEC. Kaistar is a joint venture between CEC and Epistar, one of the world’s largest LED chip manufacturers. Kaistar and Bridgelux are partners for LED packaging.

Additionally, Bridgelux currently uses Epistar to manufacture its LED chip designs. Both Kaistar and Epistar are investors in Bridgelux.

“Leveraging the momentum of our existing partnerships with CEC affiliates, complemented by a strong supply chain, world-class manufacturing, and chip, packaging and goto-market capabilities, CEC will help Bridgelux expand its technology footprint and reach more customers globally,” Bullington said in a statement.

CONSOLIDATION IN THE LED MARKET IS “LONG OVERDUE,” SAYS THE BRIDGELUX CEO.

A

n investment group led by state-owned China Electronics Corporation (CEC) and Chongqing Linkong Development Investment Company will acquire solid-state lighting startup Bridgelux.

Bridgelux will spin off its smart lighting business, Xenio, into a new standalone company. Xenio's first product is expected to ship at the end of this year. The rest of Bridgelux will become part of CEC, one of the largest IT companies in China.

Bridgelux will operate as a wholly owned U.S. subsidiary of CEC. CEC’s scope is enormous. It has

more than 60 subsidiaries, 13 holding companies and 70,000 employees. It also counts many of the world’s largest electronics and technology companies as partners, including IBM, Philips, Hitachi, Sharp and Intel.

“Bridgelux has all of the characteristics we look for in an investment, including leading technology, a broad IP portfolio and a globally recognizable brand and channel,” Liu Liehong, CEO of CEC, said in a statement. “This investment is an important step toward further aligning CEC and partner assets into a coordinated supply chain built to serve the unique requirements of the solid state lighting market.”

The acquisition will allow Bridgelux to drive down costs in an increas-

The Livermore, Calif.-based LED startup spun off its manufacturing years ago and sold its GaN-onsilicon technology to Toshiba in 2013. “This is the last step,” Bullington said of trying to be a major global LED player. “This allows us to truly focus on continuing to expand our capabilities in application-level technology and customer relationships.” He added that the acquisition would not alter Bridgelux's partnership with Toshiba.

Bullington will become the executive chairman of Xenio.

Bridgelux has raised about $225 million in venture capital. Funding has come from various investors including VantagePoint Capital Partners, DCM, El Dorado Ventures, Novus Energy Partners, IFA, Chrysalix, Harris & Harris Group, Craton Equity Partners, Jebsen Asset

Management, Kaistar Lighting and Passport Capital.

Although the terms of the deal were not disclosed, Bullington said the speculation by some Chinese media outlets that the deal was worth about $130 million was definitely inaccurate, but would only add that it was “materially more.” Bullington recently told Greentech Media the company had passed the mark of $100 million in revenue. The acquisition is expected to close in six to eight weeks.

This acquisition comes nearly one month after Cree announced it would restructure its LED business and consolidate manufacturing. Cree hopes to be better positioned to compete in the mid-power LED market and shift its consumer and commercial business to more highend applications.

Bullington readily acknowledged the LED industry is in upheaval. “No one is making money,” he said, adding that more consolidation is coming “and that’s long overdue.” Not only will the acquisition help with product costs, it will also allow Bridgelux to have a more aggressive roadmap, both in terms of geographic expansion and product portfolio.

“Now we have the balance sheet to where we can envision bolting on more capability,” said Bullington, adding that there is an appetite to consolidate even more into Bridgelux. “We can go on the offensive at this point.”
