tional Trade Fair for Solutions andTrends all about Retail. On May 13-15retail professionals from all aroundthe world came to the ShanghaiNew International Expo Centre(SNIEC) to see the latest retailtechnologies and trends for theChinese market at C-star.

China's most international retail showBeing the official satellite show ofEuroShop - the world's No. 1 retailtrade fair - C-star started as anambitious project. Now after threeshow days, Messe Düsseldorf(Shanghai) Co. Ltd., the organizer ofC-star, is proud to announce that theshow was a phenomenal success.The first edition of C-star featured anexceptionally high degree ofprofessionalism - both exhibitor-and visitor-wise. On a net exhibitionspace of 5000 square meters, C-star

featured 162 exhibitors from 23countries, among them industryleaders such as Sibu Design,Schlegel Concept, Interstore,Ezidone, Changhong Decorations,Octanorm System, LS Lighting,Nedap, Bizerba China, MettlerToledo and many more. C-star alsosaw an exceptionally high degree ofinternationalism, with nearly 50% ofits exhibitors having their headquar-ters overseas. This makes C-star themost international retail trade fair inChina and emphasizes the show'ssignificance to leading retailers fromabroad.

Visitor-wise C-star also surpassedeveryone's general expectations.Despite being held for the first time,an astonishing number of 5721visitors from 59 countries andregions came to visit the showduring the last three days, with 18%coming from overseas. Mostinternational trade visitors came from

the USA, Japan, Hong Kong,Australia, India, Russia and Canada.This further fosters C-star's status ofbeing China's most international retailshow.

C-star is organized by MesseDüsseldorf (Shanghai) Co. Ltd. andofficially supported by the EHI RetailInstitute, which is also the officialsupporter of EuroShop, C-star'smother show.

"The number of shopping malls inChina is set to double over the nextyears and Shanghai is the top retailspot in China, setting the benchmarkfor the country's retail business. Itonly makes sense that we camehere to start C-star. We have broughtour expertise from Düsseldorf toShanghai and everyone believes inthe potential and the future growthof C-star!", says Mr. Hans WernerReinhard, Managing Director ofMesse Düsseldorf GmbH and

Chairman of Messe Düsseldorf ChinaLtd. Also, Mr. Michael Gerling, CEOof the EHI Retail Institute added:"China will soon become theworld's largest retail market, so it wasthe right time and the right decisionto start C-star now!".

High acclaim from all participantsThe show also saw many compa-nies, who have been EuroShopexhibitors for many years: "When C-star was launched at last year'sEuroShop we were very excited toexhibit in China for the first time. Wehave been on board with C-starfrom the very beginning and wewant to develop the show togetherwith Messe Düsseldorf. You willdefinitely also see us next year at C-star!", said Mike Boeffert, ManagingDirector of Schlegel (Ningbo) Co.,Ltd.

In general, C-star exhibitors wereexcited about the high quality of the

show's trade visitors. Mr. Wang Yue,Director of Changhong Decorationsmentioned that "it's very fascinatingto see the never ending visitor flowin the hall. We also had manypotential clients visiting our booth inthe past days and are more thansatisfied to be here at C-star".

However, C-star is much more thana trade show as it featured anextensive supporting program. OnMay 12, one day prior to the show,C-star's supporting program kickedoff with the C-star Retail Tour. This fullday guided tour introducedShanghai's most exciting shoppingdestinations to international retailersto give them exclusive insights intoShanghai's retail market and also helpthem to better understand theneeds and requirements of Chinesecustomers.

During the first two show days theC-star Retail Conference, thehighlight of the show's supportingprogram, took place in the KerryHotel Pudong, right next to thefairground. There, leading industryprofessionals came together for twodays to discuss how retailers canturn their physical stores intopreferred shopping destinationsagain, despite rising e-commerceand online shopping. The confer-ence featured numerous keynotespeakers from leading internationaland Chinese retailers such asMETRO, Walmart or Yi-Hao-Dian. Thisgave retailers the unique chance toexpand not only their knowledgebut also their business circle. Mr.Lutz Bethge, President of theMontblanc Foundation and speakerat the C-star Retail Conference notedthat "C-star had covered anexceptionally wide range of retailcategories! Personally speaking, Ireally liked the combination ofhaving more than 160 exhibitorshere at a trade show and alsoholding a conference at the sametime, where leading industry peersare speaking about the latest offlineand online retail trends".

During the whole show time, C-staralso featured the "Designer Village", aspecial exhibition area whereinternational renowned retail designagencies presented their latestinnovations for the Chinese market.

The concept behind the C-starDesigner Village is to address therising demands of Chinesecustomers regarding their shoppingexperience, as sophisticated shopdesigns and retail solutions arebecoming increasingly important inChina's retail industry. The fact that C-star is the only retail show in Chinawith a designated design area makesit one of its kind. Both visitors andexhibitors of C-star exhibitors weredelighted to see the show'ssophisticated and advanced boothdesigns. As Ms. Elke Moebius,Project Director of C-star's mothershow EuroShop, noted: "We havenot only seen 162 exhibitors from23 countries but also a very highlevel of stand constructions andadvanced booth designs - indeednot bad for an inaugural trade showin China".

2015 Show Glimpses


There is no one template for anenergy-efficient house. Theneeds depend on where in the

world the house is located. Therequirements for a temperateclimate, with wide swings intemperature throughout the year, arevery different from those for a hotdry climate, which may cool sharplyat night, or a hot humid climate,which has very little temperaturechange from day to night.

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

maximize the Sun's heating effect inthe winter months and to minimize itduring the summer. To do this thehouse should be rectangular but ascompact as possible. The longestwall of the house should be full ofwindows and facing the equator; inthe Northern Hemisphere this wallwould face south, and in theSouthern Hemisphere the orienta-tion would be reversed. Closer tothe equator, the number and size ofwindows will be reduced.

Another factor to consider inchoosing a site for a house is wind.

In cool and temperate climates thewind can significantly affect energyefficiency. To counteract this, hillsmay provide protection, and treescan be used as windbreaks. In hotclimates the wind is an importantcooling factor. Houses should bepositioned to take maximumadvantage of breezes, whileconstruction features and trees maybe used to channel them into thehouse.

Once the house is positioned onthe lot, the next consideration is thestructure of the house. Builders refer

to the actual structure of a house asthe “building envelope.” The walls,roof, windows, and doors are whatseparate indoors from outdoors andcontrol the flow of energy into andout of the house. Different climatesrequire different design strategiesand different materials. Anotherconsideration is the typical materialfor a region, and what would be agood option for energy efficiency.In addition, most people will want ahouse that fits the style of the regionthey live in. All these factors mustmesh with the energy-efficiencyrequirements.

Dubai’s Box Park, the BananaIsland Resort by Anantara inQatar, and Tehran’s Arg

Center are among the region’s mostoutstanding architectural lightingprojects that will contest for theultimate accolade at the 3rd annualLight Middle East Awards next weekin Dubai.

The three projects are among ashortlist of 32 finalists from morethan 116 submissions throughoutthe Middle East, with the 30 percent year-on-year growth in entriesunderlining the popularity of theregion’s most respected awardsevent for lighting design community.

The Light Middle East 2015 Awardscomprises ten categories – sevenproject and three product catego-ries – and will be celebrated at a galadinner ceremony on the final day ofthe Light Middle East trade show,which takes place from 6-8 Octoberat the Dubai International Conventionand Exhibition Centre.

Ahmed Pauwels, CEO of MesseFrankfurt Middle East, the organiserof Light Middle East and the LightMiddle East Awards, said: “The LightMiddle East Awards was establishedto highlight and celebrate the vision,creativity, ingenuity, sustainability,and cultural identity of the MiddleEast’s most outstanding lightingdesign projects.”

“Every year we welcome anincreasingly diverse range ofprojects and products, and it bodeswell for the Middle East lightingdesign industry that a growingnumber of regionally-based lightingdesign firms are eager to showcase

their finest work on a global stage.”Dubai’s Box Park, designed byMeraas Holding-Sudio M, iscontesting both the Exterior RetailLighting Project of the year and thePublic Lighting Project of the yearcategories at the Light Middle EastAwards. The project drawsinspiration from theatre and is basedon a series of metal containersstacked on each other creating amosaic of riveting colours forpeople walking along the thorough-fare.

The Jumeirah-located retail complexincorporates select layers of lightfalling across facades, creating aniconic setting resembling some ofthe world's most famed urbansettings such as London's Harrod's,Paris' Moulin Rouge or New York'sTimes Square.

Another in the Exterior Retail LightingProject category is the Arg Centre, alarge commercial complex locatednear Tajrish Square in the Iraniancapital Tehran. Architectural styleand lighting of this centre have beendesigned in a way to strengthen therelationship between the complexand the public and create an urban

When three wide-eyedgraduates of Rhode IslandSchool of Design

introduced a rough-and-readylighting and furniture collection in2008, it would have been easy towrite them off as attention-seekingpranksters. Their Excel floor lamp —named after the popular softwareprogram — looked as though itwere cobbled together from oldbroom handles, like a D.I.Y.sculpture.

And then there was their firm’sname, which bordered onobnoxious: Rich Brilliant Willing, withthe preppy-sounding monogramRBW.

Seven years later, the former

classmates have proved theypossess not only staying power, butenough talent to fuel rapid growth.The firm’s influence is arguablynowhere more visible than in theoffices of Silicon Valley start-ups,where RBW lights have become derigueur. The headquarters of Uber,Yelp, Fitbit, Beats, Zazzle and Nest,for instance, all glow from thesignature lamps.

The firm’s moniker is even forgivableonce you realize it is merely a playon their names: Theo Richardson,32; Charles Brill, 31; and AlexWilliams, 32.

“When we started, we had a drillpress and a certain tongue-in-cheekflavor and attitude,” Mr. Brill said after

offering a tour of the firm’s newFlatiron district showroom, aManhattan outpost for the Brooklyn-based operation.

Since then, Mr. Richardson added:“We’ve refined our eye, along withthe skills and systems necessary tocreate a polished product. We takesome cues from minimalism, butwe’re not making products that aredevoid of character; they’reexpressive, warm and simple.”

Their latest products include theCrisp, a puck-shaped cast-glassceiling lamp with a surface reminis-cent of a rippled potato chip (anadditional corrugated brass reflectoris an option), and Queue, a modularlinear pendant lamp with a stepped

profile that could theoreticallyextend into infinity. With a portfolioof similarly intriguing pieces, Mr.Richardson said, “We have beenroughly doubling our sales everyyear for the last three years.”

The Crisp light.In addition to RBW being a SiliconValley favorite, prominent designfirms like Rockwell Group, MeyerDavis, and Yabu Pushelberg areinstalling its fixtures in upscaleresidential towers, hotels andrestaurants. A range of internationalretailers, including the Conran Shopbased in the Britain, is also rampingup sales abroad.

“Their pieces are beautiful and havethis attention to detail and craftsman-ship that you don’t get with a lot ofmajor manufacturers,” said DeniseCherry, a principal of the SanFrancisco interior design firm StudioO+A, which conceived the designfor the offices of Uber, Yelp andZazzle.

“But they also have that extra level ofinnovation, technology andsustainability,” she noted, whichmakes the products a natural fit for

tech companies.

Since 2012, RBW has exclusivelyused LEDs in its new lights (its olderhalogen models are in the processof being redesigned). And it puts anemphasis on making the technologyeasy to use.

But just because the company isworking with the latest technology,that does not mean its designs aretechie. Quite the contrary. RBWproducts maintain the soul ofsculptural, incandescent fixtures witha hint of America’s industrial past,using handsome, time-testedmaterials such as handblown glass,perforated metal, and solid oak andwalnut.

“What I like, and what the techcompanies like, is the softness oftheir fixtures,” said Lucas Martin, asenior designer at Rapt Studio in SanFrancisco. “They almost look likethey’re made by hand,” he added,in a sea of “cold, commercial LEDfixtures.”

As the lead designer for Fitbit’soffices, Mr. Martin used RBW’sRadient sconces, which resemblefloating circles of wood withconcealed LEDs that illuminate thewall behind, to recreate the fitnesscompany’s logo behind itsreception desk.

If there is a handmade quality toRBW’s fixtures, it is because thefirm’s team of 14 people assemblesevery lamp by hand using customparts. The firm had tried licensing itsproducts to manufacturers, as mostlighting designers do, but found itmore profitable to keep themanufacturing in-house.

The move also allowed it todrastically cut lead times and offerquick customization for specialorders, which helps keep clientshappy.

“We’ve built a long-term relationshipwith them,” said David Rockwell,founder of the New York designjuggernaut Rockwell Group. His firmhas developed numerous custom

fixtures with RBW for luxuryresidential buildings in Manhattan,Miami and Washington, and for theLincoln Center’s film center.“I like that they’re able to createenergy-efficient fixtures that don’tremind you of those remedial shoespeople wear when they’re trying tobe healthy,” Mr. Rockwell said.“There’s also something about theirenergy and can-do attitude.”

Indeed, when you talk with thepartners, they come off as consci-entious hard workers, willing to dojust about anything to please theircustomers. But they also periodicallylight up with moments of unre-served ambition.

“We’re just trying to do one thingreally, really well,” Mr. Richardsonsaid. “The point of our fixtures is notthat we love LEDs or technology. It’sjust that we offer something better.”

Lighting the Future with EnergyEfficiencyLED LIGHTING OPERATION AND BENEFITS

Light emitting diodes, commonlycalled LEDs, are becoming moreand more widespread in all uses

from small flashlights to laptops,cellular phones, and televisions. Youmay think they are a new inventionbut they have been in commercialuse since the 1970s as replace-ments for incandescent and neonindicator lights on electronicequipment. It has only been recentlythat LED manufacturing has reacheda point where LEDs can be used toreplace conventional lighting such asincandescent and fluorescent bulbs.

Before we discuss the benefits ofLEDs, let’s review how LEDs operate.LEDs differ from conventional lightsources in the manner in which theyproduce light. Incandescent lampsare composed of a tungstenfilament surrounded by a glass bulbfilled with an inert gas. The tungstenfilament is heated by electric currentuntil it glows and emits light. On theother hand, fluorescent lamps arecomposed of a glass tube coated inphosphor and a very small amountof mercury. An electric arc excitesthe mercury atoms, which emitultraviolet (UV) radiation. When theUV rays strike the phosphor coating,they are converted and emitted asvisible light.

An LED is essentially an electroniccomponent referred to as a solidstate device. When used in lighting,it is referred to as SSL (Solid StateLighting). It is composed ofcrystalline layers of semiconducting

materials to form what is called a p-n(positive- negative) junction. Theone-directional travel of electronsand electron holes flow into thejunction between the semiconduct-ing materials and combine to releaseenergy in the form of photons.Depending on the semiconductingmaterials, the emitting light can beinvisible or in the visible spectrum ofradiation. Red LEDs are based onaluminum gallium arsenide (AlGaAs),blue LEDs are made from indiumgallium nitride (InGaN) and greenfrom aluminum gallium phosphide(AlGaP). The components arecovered in an epoxy lens.

Since “white” light is necessary formost lighting applications and LED’sdo not initially produce white light, amethod of generating white lighthad to be developed.

The first method uses Red, Greenand, Blue LEDs to form multiple LEDchips sometimes referred to as anRGB-LED . By mixing multiplewavelengths of different LEDs, anapproximation of “white” light isemitted. By the use of a controller,combinations of wavelengthintensities can create a multitude ofcolors allowing the designer toadjust the white light to a specificcolor temperature. However,because of the use of three LEDs foreach chip, this type of chip is oftenmore expensive to manufacture.

The second method uses a singleblue Indium-Gallium-Nitride (InGaN)LED with a yellow phosphor coatingto create white light. This is themethod that results in the morecommonly seen “white LED”. Thelow cost and sufficient performancemakes it the most widely usedtechnology for general LED lightingtoday. The disadvantage is the


inability to dynamically change thecharacter of the light and the factthat phosphor conversion reducesthe efficiency of the device.

LEDs come in two different basiccategories, low power and highpower. Low power LEDs are typically0.1 watt, low current (~20milliamps) and low voltage (3.2 voltsDC). This type is used as indicators

due to the small output of light,around 2 to 4 lumens. High powerLEDs are manufactured in 1 to 3 wattpackages, high current (350-1000milliamps) and currently maximum138 lumens per watt and are thetype used for lighting. Compare thisto a 100 watt incandescent bulb at17 lumens per watt, a 32 watt T8fluorescent at 85 to 95 lumens perwatt, or a compact fluorescent at 48

to 60 lumens per watt.

Because the light output ofindividual light-emitting diodes issmall compared to incandescentand compact fluorescent lamps,multiple diodes are typicallyarranged in arrays to achieve thedesired light (lumen) output. Withsome units, the LED array is an of theLED Module System made of the

LED modules, power supply andcontrol interface modules. Thisallows for a building block approachto create a variety of lightingpatterns. There are now commercialLED lamps that are designed toreplace incandescent quartzhalogen lamps such as MR and PARand fluorescent T8 36w lamps inexisting installations without theneed to replace the fixture.


integral part of the luminaire/fixture,unlike an incandescent light sourcewhere you replace the bulb when itfails. There are several reasons whythe LED array is part of the fixture.The main reason is heat dissipation.The fixture is designed in conjunc-tion with the LED array to properlydissipate the heat generated by themany individual LED chips. LEDs losetheir efficiency if allowed to heat up.There has also been the introductionFrom learning about the operation ofLEDs you probably have realized thevarious benefits of using LEDs for alighting source. So, to help solidifyyour thoughts on LEDS, here areexcerpts from two energy reportsgiving you some percentages ofsavings.

According to the ICT for EnergyEfficiency report compiled by theAd-Hoc Advisory Group (EuropeanCommission) composed ofInformation and CommunicationsTechnologies providers, industryassociations, end-users includingregional and city groups as well asleading academics:

“Solid-state light sources, i.e. light-emitting diodes (LED) and organiclight emitting diodes (OLED), may inthe future outperform almost allother light sources in terms ofefficiency and thus provide a savingpotential of about 50% of theelectrical energy used for lighting.

If the advanced LED technology iscombined with intelligent lightmanagement systems, which willcontrol the light output according toambient lighting conditions orpeople’s presence, another 20%can be saved – in sum 70%.”But it doesn’t end there with thetremendous energy efficiency of theLED’s.

There are also environmental aspectsthat need to be mentioned. Theability to direct the light from LEDfixtures toward the desired areareduces light pollution. As well,LEDs do not contain mercury, lead,or glass.

In January of 2011, the DOE (USDepartment of Energy) released areport that targets the use of LEDlighting in 12 specific product types

spread over three general catego-ries: general illumination, outdoorlighting, and consumer electronicdisplays. For general illuminationapplications, four markets wereanalyzed: PAR, BR, and R-shaped;MR16; 2-foot by 2-foot trofferfixtures; and general service A-type.For outdoor lighting, four marketswere analyzed: roadway, parking,area and flood, and residential. DOEalso analyzed four applications forconsumer electronic displays:televisions, laptops, monitors, andmobile handsets.

The report indicates that convertingto LED-based light sources couldapproach an estimated annual savingof 263 terawatt-hours. This is theequivalent of taking 21 millionhouseholds off the power grid. TheDOE SSL 2010 Multi-Year ProgramPlan predicts that commercial LEDluminaire efficacy will increase 155%over the next decade to 219 lumensper watt (lm/W). Assuming that theLED replacements within each nicheimprove according to the DOE’s SSL2010 Multi-Year Program Planpredictions for 2020, LED efficacyincreases the total potential energysavings dramatically to 399 TWh. Thisequates to a forecasted primaryenergy savings of the total energyrequired to power nearly 32 millionaverage U.S. households.

According to the DOE report, theadvantages other than just energysavings include: longer operatinglife, reduced radiated heat, minimallight loss, dimmability and controlla-bility, durability, enhanced perfor-mance at low temperatures, safetyimprovements, smaller package size,uniform illumination, mercuryreduction, enhanced productappearance, improved colorrendition, and lower lumendepreciation.

Now, let’s summarize the advan-tages of LEDs as well as thedisadvantages.

ADVANTAGES OF LEDSEFFICIENCY:

LEDs can produce more light perwatt than incandescent andfluorescent bulbs. This is improvingwith every new generation of LEDs.


Color: LEDs can emit light of anintended color without the use ofcolor filters that traditional lightingmethods require. This is moreefficient and can lower initial costs.As well, with the use of RGB LEDsany desired color can be achievedduring actual operation.

Cool light: In contrast to most lightsources, LEDs radiate very little heatin the form of IR that can causedamage to sensitive objects orfabrics. Wasted energy is dispersedas heat through the base of the LED.

Size: LEDs can be very small (smallerthan 2 mm) and are easily populatedonto printed circuit boards. Thisallows for the design of very lowprofile luminaires/fixtures.

On/Off time: LEDs light up veryquickly. LEDs are ideal for use inapplications that are subject tofrequent on-off cycling, unlikefluorescent lamps that burn outmore quickly when cycledfrequently, or HID lamps that requirea long time before restarting.

Life time: LEDs can have a relativelylong useful life. One reportestimates 35,000 to 50,000 hours ofuseful life, though time to completefailure may be longer. Fluorescenttubes typically are rated at about10,000 to 15,000 hours andincandescent light bulbs at 1,000–2,000 hours. Shock resistance:LEDs, being solid state components,

are difficult to damage with externalshock, unlike fluorescent andincandescent bulbs which arefragile. This makes LEDs an ideal lightsource where the fixture is subjectto vibrations and jarring.

Focus: The solid package of the LEDcan be designed to focus its light.Incandescent and fluorescentsources often require an externalreflector to collect light and direct itin a usable manner.

Environmental: LEDs do not containmercury, unlike fluorescent lamps.

Disadvantages of LEDs

High initial price: LEDs are currentlymore expensive, price per lumen,on an initial capital cost basis, thanmost conventional lighting technolo-gies.

Temperature dependence: LEDperformance largely depends on theambient temperature of theoperating environment. Adequateheat-sinking is required to maintainlong life.

There is no doubt that the use ofLEDs for lighting applications has thegreat potential to save energy andallow for new and inventive lightingmethods. They will not replacetraditional methods such asincandescent and fluorescentovernight but they are evolving into astrong contender.


Contributing to the success ofmany important buildings is abuilding-management system

based on KNX open architecture.Iain Gordon of KNX UK examines itscapabilities.

Even though there are different waysin which a building and energymanagement system (BEMS) can beimplemented. In its simplest form, itessentially comes down to thecontrol of the energy within abuilding. There are of course manydifferent types of BEMSs availablefrom many different manufacturersand some of them even have anopen architecture.

A KNX building control system is

not designed to replace or be usedinstead of a BEMS, but rather it cantake over the field control — that isto say, the room or floor control ofheating and ventilation. Once a KNXsystem is installed, it provides aninfrastructure to which differentelements of control can be added— for example, controls for lighting,blinds and shutters, security and soon.

This infrastructure provides a solidand stable platform for energyefficiency within a building so thatlighting and heating can be switchedon or off based on occupancy oroffice hours. Blinds or shutters canbe closed automatically to preserveas much as possible of the heat

generated within the building.Home automation and controlsystems such as Crestron or DALIhave their own strengths. Crestron'slies in the audio-visual sector, andDALI is a lighting-control protocolthat can function on its own. Neitherneed KNX, but both can beconnected to KNX via a gatewayand integrated within a buildingautomation system — in the case ofDALI, helping to maximise itsfunctionality.

Quite the opposite of proprietarytechnology, a KNX open-architec-ture building-control system allowsproducts from many differentmanufacturers to be connectedtogether seamlessly on the same

network — without the need forspecial application programmes ordrivers. Indeed, it is a worldwideopen protocol and is approved asEuropean Standard (CENELEC EN50090 and CEN EN 13321-1);International Standard (ISO/IEC14543-3); Chinese Standard (GB/T20965) and US Standard (ANSI/ASHRAE 135).

Multi-vendor KNX-approvedproducts can be selected on a mix-and-match basis of the bestproducts in a class and withguaranteed future compatibility withother KNX approved products. Thesystem is also very easy to extend atany later date as new bus lines cansimply be added to the existing

network.As well as lighting, heating orshutters/blinds, KNX products covera vast range of other applications.They include smart metering, energymanagement, security-monitoringsystems and audio-visual control.This level of versatility is not availablewith proprietary technology.

Illustrative of how KNX interfaceswith a building energy managementsystem is the Siemens Crystalbuilding in London. At its heart is aSiemens Desigo building energymanagement system that controlsthe building to ensure it operates inthe most energy-efficient manner.Meeting-room chilled beams, trenchheating, blinds and lighting arecontrolled using devices on a KNXnetwork. A combination ofoccupancy and CO2 sensors in themeeting rooms put these areas attheir ‘day’ setpoints only when aroom is occupied.All this capability can be controlledvia room units, and occupants canuse third-party touch screens ineach meeting room. This total roomautomation solution balances energyefficiency with occupant comfort.BMS, BEMS, control, KNX, openprotocol

In the Siemens Crystal building, KNXis teamed up with a Siemens Desigo

building energy managementsystem.

The system enables the manyrenewable building serviceselements of The Crystal to be usedat their most effective levels becauseit is compatible with a range of openprotocols such as KNX. It alsoprovides reporting features so thebuilding-management teamunderstand how energy is beingused and keep energy use withinrequired parameters.

Another example is the AVCInspiration Centre in Evolis, Belgium.Noteworthy from the energy-consumption and building-designpoints of view, it features a buildingautomation system with all servicesintegrated through KNX. Theseinclude a heat-pump system for theheating, ventilation system, solar-dependent control feature andconvenient lighting functions.

With its fully glazed facades andbright, open-plan indoor areas,buildings of this type need to beable to adapt to changing weatherconditions for maximum energyefficiency.

They must be able to find the rightbalance between heating from theSun and daylight, together with

cooling and proper ventilation at anygiven time. Therefore, its HVACequipment, indoor temperature,solar control system, safety andsecurity functions as well as artificiallighting need to respond automati-cally to external influences.

Using KNX, the system integratorwas able to meet all these criteria.The standardised KNX installationbus links the entire HVAC system —including boiler, heat pump and air-conditioning and ventilationequipment — with the rest of thebuilding automation system. In thisway heating and cooling in thebuilding can be controlled highlyefficiently throughout offices,meeting rooms, showroom, bar anda multi-purpose room.

The indoor climate can be con-trolled conveniently via mini touchpanels. Lighting in the various roomscan be operated from multi-functional controllers. In areas whereartificial lighting is needed onlysporadically, motion sensors ensureenergy-efficient lighting use.Constant lighting control in thewarehouse area using DALI withinterface to KNX also promotesenergy efficiency.

The building also uses smart metersthat continuously monitor and

record the power consumed byheating, air conditioning and lightingsystems, by coffee machines and byequipment in standby. Anynecessary optimisation steps canthen be taken.The new campus at the AmericanSchool of Dubai spans 92 900 m². Itcomprises six modern schoolbuildings, sports and art facilities aswell as outdoor areas. The school’sbuilding services are controlled byan automated KNX-based system.By choosing KNX, the buildingowner was able to meet criteria forhigh energy efficiency, ease ofinstallation, flexible technology andlow investment risk. All lighting onthe campus is controlled automati-cally via KNX. Even in the class-rooms, this reduces energyconsumption by 45% compared toconventional solutions. Presencedetectors are fitted, which onlyallow artificial lights to be switchedon when there is insufficient daylightand there are still people in thebuilding.The climate conditions in the roomsare also controlled automaticallyusing KNX room-temperaturecontrollers. After school hours,motion sensors and the CCTVsystem are activated and alerts areautomatically transmitted via a KNXGSM gateway to a security com-pany.


Two-thirds of Americans havepurchased LEDs for theirhomes, nearly double the

figure from just two years ago.

The changing landscape of LEDadoption is obvious not just in theprices on the store shelves, but alsoin shifting consumer perceptions,according to the seventh annualsurvey conducted by OsramSylvania. More people were awareof the term "LED" than "halogen" or"CFL."

It’s not just for specific purchaseslike Christmas lights, either. Instead,consumers are buying solid-statelighting for general illumination in thehome. Those who are making theswitch from compact fluorescentlights and incandescents to LEDs arelured by the color of the bulb, lowenergy use and Energy Starapproval.

The survey shows how quickly thetide is turning, but also highlights thefact that CFLs continue to dominatein terms of market share -- they werethe most purchased bulb in the past12 months. By next year, however,that could change.

More than half of the peoplesurveyed said they purchased a CFLin the past year, but LEDs were close

Number of US People Buying LEDLighting Doubled in Last Two Years

behind at 41 percent. The surveywas conducted in February, beforemajor brands rolled out LED bulbsthat are now cheaper than CFLs.

But price is not the most importantfactor for consumers, the surveyfound. Most people are looking forbrightness and longevity, areas inwhich LEDs often outperform CFLs.Among those who have not yet

purchased an LED, however, thereseems to be quite a bit of misinfor-mation about the technology'squalities and characteristics.The survey noted that in-storeproducts and displays were themost important source of informa-tion for consumers. That meansbuyers need not only attractivepackaging with the right informationdisplayed in the right way, but alsoan attractive price point that involvesinstant utility rebates or everyday lowprices. Only 18 percent of respon-dents said they go to their electricutility for information about light-bulbpurchases.

The change could continue tocome quickly, according to surveydata. Consumers who have alreadypurchased one LED will likelypurchase another the next time theyneed a light, and those who areconsidering smart-home purchasesare also more likely to buy LEDs thanCFLs. One area where price toppedthe list of concerns was connectedlighting.

In this domain, about two-thirds ofconsumers said that the price wasthe most important influenceimpacting their buying decisions. Asprices have already started to comedown in that market, functionalityand lighting capability may soonbecome more important drivers.


Lighting your home accounts forroughly 5% of its total energyusage—for the average U.S.

family, that equates to around $110each year. Luckily, switching toenergy-efficient lighting is one of thefastest and easiest ways to reduceyour energy consumption and keep

more of that money in your pocket.

Efficient lighting is so essential to asustainable home that it can evencount for up to two points in LEEDBD+C: Homes if the project team isable to use energy-efficient fixturesand lamps to meet residents'illumination needs while reducingthe home's total wattage from setbaselines.

But for those of you looking to upyour efficiency game withoutdesigning an entirely new homedon't worry, you can still make amajor difference with a few easy do-it-yourself changes, starting with

your lightbulbs.

Compact fluorescent lamps(CFLs)

You've probably seen thosepeculiarly spiral-shaped light bulbson a recent trip to the grocery store.While their contours may havecaught your eye, what you shouldreally pay attention to is their energy-saving potential. Results vary slightlydepending on design, but replacingthe old lightbulbs in your house withCFLs dramatically reduces yourenergy consumption—ENERGYSTAR®-qualified CFLs useapproximately 75% less energy than

traditional incandescents! Plus, CFLscan last up to 10 times as long.While the initial cost may be higher,these bulbs pay for themselves inless than nine months, and continueto deliver energy savings long after.

The trick to getting the most out ofyour new CFLs is proper installationand maintenance. These bulbs aresensitive to extreme temperatures,so be sure to use them in openfixtures rather than enclosed orrecessed ones, which reflect heataround the bulb and consequentlyreduce its lifespan. You'll alsomaximize your energy savings bykeeping lights with CFLs on for at

least 15 minutes at a time, somethingto keep in mind before you flip thatswitch to the "on" position.

Since CFLs do contain small amountsof mercury it is important to properlyrecycle them after use, and to takespecial precautions in the event thatone breaks. Find tips on cleanupand safe disposal.

Light-emitting diodes (LEDs)

LED bulbs are a more recentdevelopment in the world ofefficient lighting. These bulbs useonly 20-25% of the amount ofenergy consumed byincandescents, and they lastapproximately 25 times as long. Dueto more durable designs, LEDs canbe used both indoors and outside,and are available in a range of colorsfor anyone looking to add a littleextra flare to their space.

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

direction. This enables them to bemore efficient, but also means a littleextra consideration has to go intohow they are used or whichparticular LED bulb you buy. Forexample, you might not want to usean LED bulb in a table lamp, sincethe light will be directed straighttoward the ceiling, unless you'vepurchased a bulb specificallydesigned to mimic the spherical lightemission of CFLs.

As with CFLs, heat management isthe most critical factor in ensuringthe life of your LEDs—higheroperating temperatures mean fasterdegradation, so it's important to besure to purchase bulbs that arecompatible with your fixtures.

Picking the right bulb

Since CFLs and LEDs use so muchless energy than traditionalincandescents, knowing whichbulbs will suit your lighting needsmay take a little time to figure out. Tomatch the light intensity of the bulbs

you're replacing check the packageof your new bulbs for lumens (anindicator of brightness), rather thanwatts (a measure of energy use).Use the chart below to get started.CFLs and LEDs also come in a varietyof color temperatures, another thingto keep in mind when you're tryingto decide which bulb is right foryou. Color temperature is measuredon the Kelvin scale, ranging between2700K and 6500K. The lower the Kvalue, the warmer the light (meaningit gives off a more yellow tone); thehigher the K value, the cooler thelight (giving off a more blue tone).

Dimmers and sensors

Want to take your lighting efficiencyoverhaul to the next level? Considerinstalling some of these featuresthroughout your home to furthermaximize your energy savings.

Dimmers: dimming switches enablegreater control over indoor lighting,rather than simply turning a light onor off. Dimming a light reduces its

wattage and output, saving energyand increasing the lifespan of somelightbulbs. Check the packaging tomake sure the lightbulbs you'reusing are compatible with theequipment you install.

Occupancy Sensors: these devicesautomatically turn lights on whensomeone enters a room, and turnthem off again after a short period ofinactivity—perfect for those of uswho just can't seem to remember toflip the switch once we leave theroom. Sensors come in twovarieties, ultrasonic (which detectsound) and infrared (which detectheat and motion). Just be sure toplace your sensors where they willdetect activity in every part of theroom.

All around the world, homesare one of the biggestsources of carbon dioxide

(CO2) emissions. But as concernsabout the environment and globalwarming have intersected with risingenergy prices, more and morepeople want homes that use lessenergy. How can we build housesthat are energy efficient?

There are many ways to make a newbuilding energy efficient. Insulationcan be added to exterior walls,

ceilings and attics, basements,around heating and cooling ducts,and in framed floors. Covers anddampers on vents to the outside orunheated or cooled areas (such asexhaust fans and attic entries) alsohelp save energy. Energy-efficientwindows, doors and appliancesadd to the energy savings.

Energy efficiency occurs in twoways. First, the house must be ableto maintain a comfortable indoortemperature for the climate, usingthe least amount of energy possible.And a building that loses less energyis a building that uses less energy.Second, the appliances that run thehouse—the heating and coolingsystems, lights, kitchen and otherappliances—must be energyefficient. When both of these overall

approaches are maximized, thehouse will use less fossil fuels andelectricity, thus reducing CO2emissions.

The simplest route to energyefficiency: start from scratch, bybuilding a new house. A new housecan easily incorporate some of thetechniques from passive heating andcooling, along with buildingmaterials—old and new—andappliances that help minimize theuse of electricity or fossil fuel. Theconstruction of an energy-efficienthome requires careful and detailedplanning using what is called a“whole-house systems approach.”The approach looks at the interac-tion between the home, theenvironment, and the people wholive there, to determine the best

Building Standards to SaveEnergy

Santa Monica Civic Center ParkingStructure

The Santa Monica Civic CenterParking Structure, in Santa Monica,California, was built to LEEDstandards. It runs on solar power,uses fluorescent lighting andreclaimed water for landscaping andtoilets, and is built partly fromrecycled materials.

Some countries have createdprograms to indicate energy-efficient


appliances. In the United States, theEnergy Star symbol can be found ona wide range of products, includingbuilding materials and appliances.

Around the world, countries, states,and cities have developed voluntary“green” building standards. In theUnited States there is a certificationprogram called LEED (Leadership inEnergy and Environmental Design),which has been created by thenonprofit U.S. Green BuildingCouncil. It rates all aspects ofdesign, construction, and operation,mostly for large-scale construction,such as government buildings,schools, and commercial spaces.The LEED system has been adoptedin several countries, including India,Israel, and Canada. The Standards

and Industrial Research Institute ofMalaysia has recommended greenbuilding standards for that country.

In the United States, the city ofBoulder, Colorado, has developedits own elaborate point system forenergy-efficient building. Architec-tural designs will not be approvedunless they earn a certain number ofpoints, for such elements asinsulation, precast concretefoundations, planting of shade trees,and energy-efficient windows. TheBoulder program also requires thathouses be disassembled rather thantorn down and that at least 65% ofthose materials be recycled.

There are also programs to labelappliances and products that are

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


CONSOLIDATION IN THE LEDMARKET IS “LONG OVERDUE,” SAYSTHE BRIDGELUX CEO.

An investment group led bystate-owned ChinaElectronics Corporation

(CEC) and Chongqing LinkongDevelopment Investment Companywill acquire solid-state lightingstartup Bridgelux.

Bridgelux will spin off its smartlighting business, Xenio, into a newstandalone company. Xenio's firstproduct is expected to ship at theend of this year. The rest of Bridgeluxwill become part of CEC, one of thelargest IT companies in China.Bridgelux will operate as a whollyowned U.S. subsidiary of CEC.

CEC’s scope is enormous. It has

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

“Bridgelux has all of the characteris-tics we look for in an investment,including leading technology, abroad IP portfolio and a globallyrecognizable brand and channel,”Liu Liehong, CEO of CEC, said in astatement. “This investment is animportant step toward furtheraligning CEC and partner assets intoa coordinated supply chain built toserve the unique requirements ofthe solid state lighting market.”

The acquisition will allow Bridgeluxto drive down costs in an increas-

ingly competitive LED market andcompete globally on strongerfooting. “This was a transaction thatwe have designed Bridgelux to beable to enter into,” said BridgeluxCEO Brad Bullington.

Bridgelux already has strategicpartnerships with other companiesconnected to CEC. Kaistar is a jointventure between CEC and Epistar,one of the world’s largest LED chipmanufacturers. Kaistar and Bridgeluxare partners for LED packaging.Additionally, Bridgelux currently usesEpistar to manufacture its LED chipdesigns. Both Kaistar and Epistar areinvestors in Bridgelux.

“Leveraging the momentum of ourexisting partnerships with CECaffiliates, complemented by a strongsupply chain, world-class manufac-turing, and chip, packaging and go-to-market capabilities, CEC will helpBridgelux expand its technologyfootprint and reach more customersglobally,” Bullington said in astatement.

The Livermore, Calif.-based LEDstartup spun off its manufacturingyears ago and sold its GaN-on-silicon technology to Toshiba in2013. “This is the last step,”Bullington said of trying to be amajor global LED player. “This allowsus to truly focus on continuing toexpand our capabilities in applica-tion-level technology and customerrelationships.” He added that theacquisition would not alterBridgelux's partnership with Toshiba.Bullington will become the executivechairman of Xenio.

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

Although the terms of the deal werenot disclosed, Bullington said thespeculation by some Chinese mediaoutlets that the deal was worthabout $130 million was definitelyinaccurate, but would only add thatit was “materially more.” Bullingtonrecently told Greentech Media thecompany had passed the mark of$100 million in revenue. Theacquisition is expected to close insix to eight weeks.

This acquisition comes nearly onemonth after Cree announced itwould restructure its LED businessand consolidate manufacturing. Creehopes to be better positioned tocompete in the mid-power LEDmarket and shift its consumer andcommercial business to more high-end applications.

Bullington readily acknowledged theLED industry is in upheaval. “No oneis making money,” he said, addingthat more consolidation is coming“and that’s long overdue.” Not onlywill the acquisition help withproduct costs, it will also allowBridgelux to have a more aggressiveroadmap, both in terms of geo-graphic expansion and productportfolio.

“Now we have the balance sheet towhere we can envision bolting onmore capability,” said Bullington,adding that there is an appetite toconsolidate even more intoBridgelux. “We can go on theoffensive at this point.”
