“the great thing about glass is you can color it,mold it, support it horizontally and vertically, andit is very malleable.” In this issue we’re exploringglazing trends and those are some of the com-ments architect Chris Ward shared when takingpart in our one-on-one with architects, whichfocused on that subject (see full article on page 14).Ward says almost every project he does features asignificant use of glass. He’s not alone. Architectsare using glass more and more for many reasons:• Increased transparency;• Enhanced aesthetics;• Higher energy performance;• Increased safety and security; and• Advanced daylighting.

These are just a few reasons why glass seems tobe showing up in so many designs—and it’s not justhere in North America; around the world, glass isused frequently in substantial skyscrapers—from theBurj Khalifa and the Abu Dhabi NationalExhibition Company’s Capital Gate in the UAE toTaiwan’s Taipei 101, these structures push the archi-tectural limits.

Though both the Burj Khalifa (Guardian glass)and Taipei 101 (glass fabricated by Viracon) haveheld the title of the world’s tallest building, it’sactually still attributed to the Burj Khalifa, whichstands 2,717 feet and 163 floors; Taipei 101, in sec-ond place, is at 1,670 feet and 101 floors. CapitalGate (the glass was supplied by Cardinal) stands 35stories and leans 18 degrees westward.

While these mega-structures seem to sproutup often in Asia and the Middle East, you canalso find a few examples of some of the world’stallest buildings in Australia. Located along thecountry’s Gold Coast, for example, standswhat’s presently ranked as the world’s 44th

tallest building—the Q1 tower, at 1,058 feet talland 80 floors. It features a glass façade, suppliedby G. James.

Interested in more of what’s happening withthe Australian glass industry? Learn about someof the trends and how the industry is changingon page 24 of this issue. You’ll find that whilethousands of miles away, the market is not thatdifferent than what we have right here. AG

according to the U.S. Department of Energy(DOE), windows consume 30 percent of build-ing heating and cooling energy and have aneven higher impact on peak demand and occu-pant comfort. Significant improvements areneeded in building façade performance, espe-cially if the American Institute of Architects’2030 commitment to carbon neutral buildingsand the DOE’s 2030 net zero energy goal aregoing to be met.

There has been some debate recently overwhether we need to reduce the use of glass inbuildings. This is because, compared to walls, win-dows have higher heat conduction and highersolar heat gain. However, the most effective way ofimproving the energy efficiency of the façade is

not necessarily to reduce the window-to-wall ratio,but to implement integrated façades that can saveenergy by optimizing the utilization of natural day-light to offset electric lighting, which accounts for20 percent of electrical energy usage in buildings.Integrated façades combine automatically con-trolled dimmable lighting with the appropriateamount of glass in the right locations on thebuilding envelope.

Integration OptionsTo provide dynamic glare control, dynamic

glazings or automated mechanical shades withhigh-performance conventional glazing may beused. In fact, integrated façades in combinationwith highly insulating windows with dynamic

solar control are key components of the DOE’s road map for zero ener-gy commercial buildings.

Product SelectionGlazing products with increasingly higher performance and capability

are becoming available, which allows for performance optimization ofintegrated façade designs. For example, the use of triple glazing is becom-ing more prevalent in northern states with U-factors in the range of 0.18-0.23 Btu/ft2.°F when one low-E coating is used (compared with ranges of0.25-0.29 Btu/ft2.°F for dual pane low-E products with argon). The per-formance can be increased further by using low-E coatings on two sur-faces.

Active ControlFor further enhanced energy performance through variable solar con-

trol, dynamic glazing products are available and cost competitive withconventional solutions involving mechanical shading. These productsprovide a dynamic response to the changing exterior environment, pro-viding the means to capture useful daylight when available, yet block thesun’s glare and solar heat when required.

Even though it is not yet 2030, the high-performance glazing productsavailable today when combined with effective daylighting strategiesalready have the potential to deliver high-performance façades, whichmaintain the glazed area while improving energy performance and occu-pant comfort. Additional information about energy-efficient glass andglazing is also available on the Glass Association of North America’swebsite at www.glasswebsite.com/energy. AG

the project had been completed several years

before. It was an impressive design with vastexpanses of vision area and windows. Soon, thebuilding owner begins to notice a clouded effectbetween the panes of some of the insulating glass(IG) units. On closer inspection, the architectfinds something missing on the windows: the cer-tification stamp on the window spacer materialswithin the IG units that indicates testing and cer-tification to current industry standards. Theowner, architect, specifier and contractor begin atug-of-war over who is responsible and worse yet,who will replace the windows and eat the cost toinstall new units which meet third-party testingand certification programs.

No Reason Not to TestThe Insulating Glass Manufacturers Alliance

(IGMA) was one of the leaders in merging ASTME 773/E774 (alsoknown as CBA)with the CGSB(Canadian GeneralStandards Board)12.8 standard tosuccessfully com-plete a harmonizeddocument acrossthe U.S. andCanada; one thatexpands the globalmarketplace for IGunits and provides asingle cohesive andconsistent updated

certification program for manufacturers to testtheir products.

IGMA is on a mission to rid the specificationcommunity of non-certified and un-tested IGunits. Overall, the aim of the program is to pro-mote the use of the harmonized standard and ulti-mately, extend the service life of IG units.

Without proper third-party certification, there’sa chance IG units will fail, and that gives theindustry a black eye and leaves a bad taste in themouth of the end-user. The mechanism for

scientific testing and procedures have been care-fully established and documented by a consensusof industry members and third-parties and much time and effort has been spent by IGMAand other organizations to bring this document to market. There’s not a single reason to avoidtesting to this new standard—it brings a higherlevel of understanding, credibility and perform-ance to the manufacturing process in the crea-tion of IG units in the United States and Canada.

Up to You to Educate For IGCC-IGMA program participants, the

current goal is to let architects, builders and speci-fiers know there is a new ASTM standard in placefor both the U.S. and Canada, and that itincludes the more rigorous requirements of thepreceding standards. Why should architects care?Because it’s up to them to bring to their end-usersthe best performing products on the market.These products should be tested to certified stan-dards in real-world performance applications andwith the longevity of the individual unit mostimportant. No one wants to see IG units that fail,leak or worse yet, look like an eyesore in an other-wise reputable building façade.

With this updated and rigorous test standard,IG units are designed to last longer than ever,avoiding the same problem that the fictitiousbuilding owner and his contractors faced in thescenario described above. Results from the IGMA25 Year Field Correlation Study show that IGunits certified to the most stringent requirementsdemonstrate a failure rate of 3.5 percent at the 25-year mark.

The reason for certification, generally withinany standard, is to provide end users, whetherdoor and window manufacturers, building codeofficials, architects and specifiers or home buyers,the assurance they need to know they are buying aproduct that meets or exceeds the applicable codeor standard.

Sing a Songof Glass

Architectural Gem:Glazing Shines inNew Opera House








For years just the word “opera house” waslikely to conjure up images of Sydney’s famousarchitectural structure, with its sweeping peaksand pearly façade. Now, a newly constructedvenue, featuring glass as a significant designdetail, may also stake its claim as an architecturalopera house gem.

Spanning 70,000 square meters and costingapproximately $215 billion USD (1.38 billionRMB), the Guangzhou Opera House inGuangzhou, China, is located at the heart ofthe city’s cultural development. Designed byZaha Hadid Architects, the structure’s twin-boulder design was created to enhance the cityby opening it to the Pearl River, as well as unify-ing the adjacent cultural buildings.

The design of the opera house evolved fromthe concepts of a natural landscape and theinterplay between architecture and nature. Inparticular, it was also influenced by river valleys,and the way in which they are transformed byerosion.

“In Chinese culture, certain analogical think-ing makes sense and the idea of pebbles androcks on the banks of a stream is actually verymeaningful for a project located next to thePearl River,” says Zaha Hadid, the firm’s found-ing partner. “As designers, this is more of atechnique for us to articulate the relationship ofan object within a landscape; describing howthe design is informed by its context. So whendesigning the building, we were not thinking somuch of metaphor, but more in terms ofanalogy–the landscape analogy–where featuresof a natural landscape are expressed within thearchitecture.”

The use of glazing also played a significant partin the design of the opera house. For example,fold lines that include glass help define territoriesand zones within the structure that allow naturallight to penetrate deep into the building.

“Tessellated triangular glass sections emphasize

the crystalline nature of the design and openup the public areas of the opera house,” saysHadid.

KGE Engineering in Zhuhai, China, part ofChina Architectural Engineering, was awardedthe contract to undertake the design, engineering,fabrication and installation of the building enve-lope, including the glass curtainwall, glass wall,stone cladding, and roof waterproofing system.The project spanned a total area of 323,000square feet. Glass was supplied by ChinaSouthern Glass.

According to Zaha Hadid’s team in China,“One of the significant challenges in designingthe glazing was the complex geometry of thebuilding envelope, where triangular glazed unitswere flush-fitted over various angles and aroundcorners. There were also surface configurations toconsider whereby laminated glazing [was used] onall inward inclinations.”

The architects also note that “the envelope isone of the largest asymmetrical structures of itskind,” and “a variety of technological solutions,from computer design to fabrication and installa-tion” were used in order to create it.

Zaha Hadid’s work on the Guangzhou OperaHouse began in 2002 when the firm took part inan architectural competition and was selected todesign the project. The schematic design phasebegan in October 2004 and groundbreaking wasin January 2005. The project was completed lastyear and the first performance in the new operahouse was in May 2010.

Speaking of her work in China, Hadid adds,“The dynamism of China’s development isbreathtaking; throughout the entire country,you can sense the enthusiasm, ambition, andboundless energy of the upcoming generation.It is a very rewarding experience to see the com-pleted opera house and I am very grateful to thecity of Guangzhou.”

She adds, “There are very few places in theworld today where architects can find such for-ward looking, enthusiastic clients with such pas-sion for innovation … The design of the operahouse reflects China’s rich cultural history, butalso the remarkable future China will play on aworldwide stage.” AG

Seal AppealWhat if a glazing renovation could save a build-

ing owner hundreds of dollars annually in heat-ing costs? Pilkington North America says its newPilkington Spacia™, a vacuum construction thatseals low-E glass with clear float glass with a thinvacuum layer, can—and has—done just that. Thecompany reports that the technology, which hasbeen used in projects in Asia and Europe formore than a decade, helped save building ownersin Camden, London, more than $400 a year inheating costs while keeping the building’s originalcharacter intact.

Now commercially available in North America,Pilkington Spacia provides an option for balanc-ing historical preservation with modern comfortand environmental requirements. With its overallslim profile, the new technology can be used inexisting frames in older buildings, maintainingthe building’s original aesthetics while providingmodern comfort.

“Pilkington Spacia offers the thermal perform-ance of conventional double glazing in one quar-ter of the thickness and two thirds the weight,”says Sharon Urban, marketing communicationspecialist with Pilkington North America. “It’sideal for older, traditional, commercial and resi-dential buildings and is also suitable for applica-tions where the use of thinner, low-weight glazingwould be desirable, such as in sliding windows,secondary glazing or as one pane of a triple-glazed unit.”

Not only is Pilkington Spacia designed tohelp improve energy costs, but it can alsoimprove acoustic performance and, compared tosingle glazing, offers improved thermal insula-tion. The vacuum gap helps to minimize heatflow by minimizing convection and conductionbetween the glass panes.

“The most significant feature of PilkingtonSpacia is that it provides substantially improvedthermal performance compared to conventionaldouble glazing. It offers the thermal performanceof modern double glazing in the same thicknessas single glass, offering the opportunity toimprove energy efficiency in older, traditionalbuildings,” says Urban, adding that it is also acost-effective method of improving the energy

efficiency of older homes where glazing choicesare restricted or where the original frames are adesirable feature.

Unlike traditional double-glazing, with thisproduct the air between the two lites of glass isextracted, creating a vacuum. The gap betweenthe two panes can be reduced to just 0.2 mm,providing an overall thickness of just more than 6mm. Heat loss through radiation is limitedthrough one of the glass panes having a low-Ecoating, similar to that used in conventional,modern double glazing.→ www.pilkington.com/na

Seeing ClearlyFrom exterior glass facades to interior and dec-

orative glass applications, a new glazing develop-ment from the Swiss company SEFAR has madeits way to North America and can help bring aunique aesthetic to architectural designs. It’scalled Vision and is a metal-coated precision fab-ric interlayer, typically laminated within glass orother transparent materials.

“SEFAR Architecture Vision offers an unparal-leled aesthetic and functional attributeswhen compared to other interlayer and glazingproducts,” says Peter Katcha, director, NorthAmerican sales for SEFAR Architecture. “It uti-lizes metal-coated fabrics with various apertures tocreate unprecedented depth and a reflective quali-ty without overwhelming glare. Vision fabricinterlayers uniquely feature the metal coating onone side, allowing the material to be seen throughfrom the back side.”

N e w P r o d u c t F o c u s





http://www.pilkington.com/na





Katcha adds that the new product createsreflective depth in glass through precise fabricweaves and metal coatings.

“With 30 standard possible combinations offabric and metal coatings, which include copper,chrome, aluminum, titanium, andaluminum/copper, along with the ability to printUV-stabilized colors, the Vision fabric interlayercan create endless color or pattern possibilities inboth laminated glass and IGUs.”

In addition, the metallic-coated interlayer fabricsare printable with UV stabilized inks to producePantone colors, patterns, and other design effects.Likewise, with its unique metal coatings Vision fab-ric interlayer is designed to help improve the ther-mal insulating qualities for reducing solar heat gainwhile allowing for light transmission. The range ofmaterials can also be double-sided.

“We’ve been anxious to unveil Vision becauseboth its look and function surpass any otherproduct on the market,” says Katcha. “With amaterial density of up to 27 threads per centime-ter, Vision’s metal coatings deliver significantlymore facets for light reflection and interactionwith its environment than any other interlayeror metal mesh product. At the same time, youcan still see through it from the inside, whichis a unique feature for similar glass laminatedproducts.”

The fabrics are available in six fabric density con-figurations and each can be coated with six differ-ent metal coatings, ultimately providing 36 differentcombinations. They feature plain or twill weaves ina variety of aperture percentages and light transmis-sion percentages.→ www.sefar.us

Wide OpeningsAs the all-glass look continues to increase in interest and

demand, companies are developing new products to meet thoseneeds, including Mill Valley, Calif.-based NanaWall Systems,which recently launched its NanaGlass® SL25, a frameless open-ing glass wall system installed on the exterior of balconies. Thenew system has no vertical stiles and can provide uninterruptedviews and natural light while still forming an insulating airpocket over the building facade.

“The NanaGlass SL25 provides a solution for increasing livingspace, enhancing an aging building’s value, preservation and pre-ventative maintenance issues, improving overall energy efficien-cies, and building modernization,” says Ebrahim Nana, presidentof NanaWall Systems. “No side stiles create uninterrupted views,purposefully engineered to take advantage of the passive solareffect that increases heating and cooling efficiency, lowering thebuildings carbon emissions output.”

In new or existing multi-tenant buildings with balconies thesystem can be installed on the top or behind the rail. It can alsobe used in restaurants, stadiums, interior offices, porches, schools and storefronts, among other applications.

The NanaGlass SL25 all-glass operable panels are engineered to withstand the elements and transform balconies into year-round usablespace. In fact, the system can handle wind loads up to 80 stories depending upon the building location in 90 mile-per-hour wind zones.

In addition, the panels can slide wide open and stack to one or both sides for natural ventilation or close quickly to protect thebalcony from wind, rain, pests and birds. The individual sliding panels are top-supported in a single track and can ride a fixed bal-cony railing or extend all the way to the floor.

The new system is available in custom sizes and configurations and each individual panel can be a maximum of 2 feet 7 incheswide by 9 feet tall in 3/8-inch or 1/2-inch glass.→ www.nanawall.com AG

AGG: What glazing features do you find most attractive?PS: Glass offers the unique ability among archi-tectural products to perform multiple functionsthrough a transparent surface. We use glass toform enclosures, provide views and light, excluderadiant energy, resist structural forces and createan artistic backdrop or screen. Glass is probablythe most versatile building material that we use.AGG: How extensively do you work with glass?PS: Our designs include a broad range of proj-ects with just as broad of a range of design crite-ria. Glass use runs from being strictly utilitarianto being a major design feature. Our most signifi-cant buildings use glass in some way as a majordesign element, acting both functionally and aes-thetically within the overall design.AGG: What are some unique projects with whichyou’ve been involved?PS: CSO Architects has been involved with arange of such projects. The Palladium at theCenter for the Performing Arts in Carmel, Ind.,is a 1,600-seat music performance hall, completedin 2010, that includes a movable canopy of glass

reflectors over the performance platform. It is thelargest such installation in the world. Its fourmovable sections are used to help tune the hallfor various types of music performances. Glasswas chosen so the intricate plaster dome workand ornamentation of the hall ceiling would notbe obscured. Each section of glass is laminatedand varies in size, shape and thickness to maxi-mize sound dispersion. Where similar halls usereflecting clouds of solid materials for the samepurpose, glass is used to achieve the requiredacoustical performance without obscuring theclassical architectural features of the hall.

The Indianapolis Airport Terminal, completedin 2008, was the first all new airport terminaldesigned after 9/11. As such, it incorporates newparadigms for the security operations of the termi-nal. Despite security concerns, design architectsHOK made glass the centerpiece of thedesign. With its expansive curtainwall front and100-foot diameter cable-supported central skylight,security appears to be the least important criteriaof the design. The glass envelope is designed towithstand specific blast threats and the building isalso seeking LEED certification, proving that light-ness, security and energy performance can all beobtained with a glass envelope.

hen it comes to glass, building designs and trends have changed a lot in the past three decades. In the 1980s itwas all about the shiny, highly reflective glass box that rendered a low visible light transmittance and low solarheat gain coefficient. By the 1990s, low-E coatings began making their way into the market and energy codechanges called for better performance. Today, with the accelerating drive toward going green and meetingLeadership in Energy and Environmental Design (LEED) requirements, more and more designs call for daylight-ing, higher visible light and more transparency.Without a doubt, the role that glass can play in terms of energy efficiency is one of the biggest reasons for

its use. But performance aside, there are a lot of other architectural reasons for using glass. These can rangefrom decorative appeal, colorful options, safety and security.So just what, specifically, are architects thinking when it comes to glass? This month the Architects’ Guide to

Glass & Metal magazine caught up with several architects around the country and asked them to weigh in onglazing trends and why they use glass in their designs. While their reasons varied, common themes includedperformance and aesthetics.

Architects Talk about Glazing Trends, Benefits and Why they Opt for Glass by Ellen Rogers









The New Commons in Columbus, Ind., is areplacement of the signature design by Cesar Pellithat acted as the gateway to Columbus architec-ture for thousands of visitors. The original, planardark glass design was replaced with a faceted,high-performance clear glass design utilizing theoriginal building frame as homage to Pelli’swork. The change in transparency and articula-tion of the glass wall makes it a more inviting,human-scaled building that expresses the celebra-tory nature of the revived facility.AGG: What are some reasons for using glassarchitecturally?PS: People thrive in natural light. We likeviews. We like controlled sunlight. We tend torespond favorably to the decorative affects we canachieve with glass. Glass emphasizes our humani-ty, since our views through it make us relate inscale to whatever we see. Through it we canextend ourselves into the landscape (or urban-scape). Reflection can also expand or expose theworld around us.AGG: What are some current glazing trends?PS: First, increased thermal performance optionsto maximize building energy performance whileincreasing visible light transmittance. As thermalperformance increases, so will the extent of visionglazing in buildings. Energy conservation codesforce us to optimize envelope designs and we arebecoming more sophisticated as designers, tuningbuilding envelopes to balance competing crite-ria. Our glazing choices are improving, from coat-ings that allow us to get better performance out ofstandard insulating units to sophisticated multi-ple-layer insulating units with R-values approach-ing those of the average wall values of just a fewyears ago.

Second, we are continuing to see growth in dec-orative and artistic glass. The number of producersof cast, molded, formed, coated and colored glassesis increasing. We are finding more ways to usethese unique and artistic products and to addinterest and highlights to our interior spaces. Glass

adds sparkle, transparency, color,form and texture in a way unlikeany other product.

Third, designers are becomingmore confident in using coloredglazing and being creative withcolor. Colored glazing has tendedto be monolithic. The wide rangeof glass colors combined with lami-nating colors has broadened ourability to make glass a color ele-ment in our designs. We will beginto realize the opportunities ofusing patterns of colored glazing tomake more vibrant designs or tomimic the color patterns weachieve with other materials.

AGG:What glazing features do you find most attractive?CW:We use glass in many different applicationsand for more than just fenestration (i.e. interiorwalls, partitions, etc.). We can we add color andimagery to the glass to make it more interesting.The great thing about working with glass is youcan color it, mold it, support it horizontally andvertically and it is very malleable.AGG: How extensively do you work with glass?CW: All of our projects have a distinctive glasselement, which has become one of CWA’s signa-ture architectural features. I would say that all ofour projects start with the question, what can wedo that is different and exciting? And almostalways the answer includes using glass as a featurein the design.AGG: What are some unique projects with whichyou’ve been involved?CW: Two elementary schools we did have unique

glass elements. One has a glass tree curtainwalland a multi-colored skylight and the other, nowbeing built, will feature a wall with multipleimages related to the school’s values and missionstatement. Another project now under construc-tion uses glass as a reflective landscape inside aretirement home. And at the Tournament ofRoses headquarters in Pasadena, Calif., we creat-ed exterior walls completely of glass, so people intheir offices will feel as though they are workingin the gardens.AGG: What are some reasons for using glassarchitecturally?CW: Glass gives you a lot of bang for the buckand is a material that people understand easily.By using glass and manipulating the color,shape and form people can still comprehend it,even though the technological advances [used tocreate it] may be very difficult tounderstand. Another great reason to use glass isthat philosophically it almost always denotes fen-estration, or an opening to the outside. Eventhough you have a completely interior space, byusing glass as a medium for supporting an imagein a large expanse, you can create the sense ofoutdoor space where none existed before.AGG: What are some current glazing trends?

CW: We are imposing imagery on glass and usingmulti-colored glass in curtainwalls to create inter-est. Also, we are starting to use it structurally forinterior dividers, incorporating it with varyingopacities more and more.

Ennead Architects, New York City

AGG: What glazing features do you find most attractive?CM: Architectural glazing options, particularlyfor façades, are increasingly complex. Currentglazing technologies provide a wide range ofdesign and performance characteristics thatallow architects to balance aesthetic intent,building orientation, solar and thermal loadsand occupant comfort. Features such as low-Ecoatings, which have been around for sometime, are nearly ubiquitous for any building thatincorporates significant areas of glass. Coatingtechnology has advanced dramatically over thelast ten years to provide improved solar perform-ance while simultaneously becoming more neu-tral in transmitted color. Ceramic frit technolo-gy, while also not new, is now more prevalentthan ever, with many buildings utilizing 30- to60-percent coverage patterns to shade the build-ing and reduce load on the building’s AC sys-

tems. Frit patterns are nearly limitless in design,and some glass fabricators offer a dual-colorapplication, with one color facing outward andanother into the building, allowing glare issuesto be addressed. Insulating glass units are anobvious choice for all façades. However, triple-glazed units can be substantiated if projectbudgets allow and payback can also besubstantiated.AGG: How extensively do you work with glass?CM: Many of our projects include extensive areasof glazing, depending on the program and siting—anywhere from 20- to 50-percent glazing is notuncommon. This statistic is somewhat meaning-less, though, given that a large building caninclude a tremendous amount of glass eventhough the overall area of glass as a percentage ofthe entire building enclosure may be small.Percentage of glazing is increasingly driven byenergy-code requirements. Codes require mini-mum performance values of glazing, includingshading coefficients (solar gain) and U-values(thermal loss).

AGG: What are some unique projects with whichyou’ve been involved?CM: The Weill Cornell Medical College’s WeillGreenberg Center incorporates white ceramic frit-ted glass and low-iron glass to create a monolithicwhite glass building that softens the natural lightto the interiors. In addition, the college’s MedicalResearch Building features a double skin, all-glassfaçade, which includes an inner wall of low-Ecoated insulating glass, and an outer wall of lami-nated, double-fritted (black and white) glass thatfunctions as a parallel sunshade.

The Westchester Community College GatewayCenter project in Valhalla, N.Y., utilizes low-iron,double-glazed units to create maximum trans-parency in the building’s entrance atrium. Frittedand low-E coated units are also used to boost per-formance and shade the atrium space.AGG: What are some reasons for using glassarchitecturally?CM: Among the important elements of ourdesign process is the exploration of new materialsand systems. We have been investigating the aes-thetic and functional opportunities afforded byglass for well over 20 years. As glass technologyhas advanced, so too, have our experiments.

In addition, clients are recognizing the powerfulimpact that glass can provide. Glass façades havean aesthetic appeal to many clients who appreciatean expression of the technology behind it (i.e.large areas of glass and systems to support thatglass). And when done well, glass façades can con-tribute to the establishment of a strong institution-al identity as clients seek to recognize and elevatethe stature of their intellectual community.

It is interesting to note that clients specificallyrequest that we incorporate glass—and often sig-nificant amounts—into our designs. For example,the desire to increase the amount of daylight thatpenetrates into a building center typically requiresthat we use increased areas of glass or façadedesign features that reflect more light inward.Today, I think everyone sees that both architectand client are concerned with building projectsthat are sustainable. Glass is not a good insulatorof buildings, and significant heat loss and heatgain occur through vision glazing. This has a bigimpact on energy use, and many times daylightingdecisions are driven by sustainable or LEEDgoals. That being said, glazing and curtainwallfabrication technologies are constantly improv-ing—with better performing low-E coatings to

reduce heat gain and better curtainwall framingsystems that reduce heat loss. With a well-designed curtainwall unit frame utilizing triple-glazed and low-E coated glass, U-values can be sig-nificantly better than those of a standard dual-glazed unit that simply meets code.AGG: What are some current glazing trends?CM: The glazing industry is currently pre-occu-pied with thermal performance. Many solutionsare currently available that address thermalloads such as photovoltaic glazing units, span-drel units that capture solar heat and redistrib-ute it to the building mechanical systems, dou-ble façades, and low-E coatings that reject moreand more solar load away from the buildinginterior. There are also many developments inother areas such as laminated films, which offera wide variety of color choices; glass coatingtechnologies that address radio frequency issuessuch as cell phone signal strength; and structur-al innovations allowing nearly all-glass construc-tion for applications such as stairs and otherload-bearing elements.

sCloserthan You ThinkAustralia May Seem Like a Far-Off Place, But You’ll Find that the Glazing Similarities are Many

by Ellen Rogers

ooner or later the glazing trends rooted inEuropean designs cross the pond and maketheir way into North American mainstreamarchitecture. Curved glass, large glass openingsand the most recently discussed double-skinfacades (see related article on page 8 of theJuly/August issue), saw popularity in Europebefore coming to America.

And in another corner of the globe, thou-sands and thousands of miles away from theNorth American mainland, another country’sglass industry is quickly evolving into a signifi-cant architectural venue. From energy and envi-ronmental awareness to increased transparencyand large glass sizes, the trends and demands ofthe Australian glass industry are not unlikethose of the United States and Europe.

The Architects’ Guide to Glass spoke with JoeFinn, managing director for Bent & CurvedGlass Pty Ltd. in Revesby, New South Wales,Australia. Finn says in many ways the trends inAustralia have reflected the changes of Europeas well as those of the United States.

“We have seen a move to more safety glassand thicker glass,” says Finn. “The growth ofstructural interlayers is making a big impact atthe moment, especially for balustrades as it canremove the need for a handrail and offer amore unobstructed view.”

For architects, he says, it’s all about glassthat’s as large and as big as possible.

“Architects are looking for larger and bigger—sizes, spans, less structure, fewer fittings andhence more transparency,” says Finn.“Innovative designers push the envelope of pos-sibility and the glass industry is challenged to

A variety of high-risestructures and styles canbe seen along the area ofAustralia’s Gold Coast.

respond to achieve greater thermal and structur-al performance; more complex shapes in glass;fewer connections and less structure to supportthe glass; and the integration of other decora-tive materials with and within the glass.”

Likewise, the trend toward structural glazingis also growing. Finn says while common incommercial applications,this trend is movinginto a secondary stage for use in projects thatinclude residential and light commercial.

“Stair treads, balustrades, floor panels, poolwindows and wet edges, roof lights and domesin multilaminate make-ups incorporating combi-nations of annealed, heat-strengthened and tem-pered glass with standard and specialized struc-tural interlayers are now more commonly speci-fied with support from engineers and glass man-ufacturers making these previously exclusiveproducts accessible and affordable for a widerrange of projects,” says Finn.

As far as other trends, Australia is also mov-ing to more energy-efficient glazing.

Geoff Rankin, one of Solutia’s Australiansales managers, says current trends are focusedon high-performance glass and glazing.

“That would include energy-efficient glassand glazing as well as increased use of acousticlaminates.”

Finn adds, “Legislation is still weak for thispush, thus the industry has a vast overcapacitycompared with demand.”

But the industry is hard at work to changethat.

“The development of coated and/or tintedglass and its combination into a double- ortriple-glazed unit and coupled with thermalframes are positioning glass to be a solution tothe energy puzzle,” says Finn. “People don’t










want to work or live in windowless boxes andcrave natural light in and views out, so glass hasto evolve to meet these demands and not have anegative effect on the thermal performance ofthe building.”

This ties right into one challenge the indus-try is facing—maximizing glazing to allow inlight and views out while still achieving higherlevels of the required thermal performance.

Finn says the awareness of each building’scarbon footprint is also growing.

“The cradle-to-grave lifecycle will becomemore important in the years to come for manybuilding products and structures,” he says.

Australia is also facing a number of chal-lenges, not unlike those of North America.

“The effect of imports, mainly from China,has grown in the last number of years with

many now importing bulk glass and finishedproducts into the market,” says Finn. “This isnot only happening within the industry, butalso by our traditional customers now importingglass themselves.”

Rankin adds, “Other trends which aren’t sogood for local industry include the level ofimport competition for large-scale building proj-ects where a lot of work has been lost overseasdue in part to a very high Australian dollar.This even extends to façades. This is why localmanufacturers are working hard to bring greatervalue to the market place, enabling higher per-formance products into market segments suchas residential.”

And just as the devastation and, ultimately,awareness brought on in North America as aresult of natural disasters, such as hurricanes,glazing codes and requirements in Australiahave also been impacted as a result of similaroccurrences.

“Recent cyclones in northern coastal areasof Australia have seen a review of the glazingrequirements of these areas,” says Finn. “Atpresent, this is causing debate and I wouldexpect more stringent glazing requirements tocome into effect in the short to mediumterm.”

He adds, “Bushfires, which affected manyhomes, have also seen a review of the glazingrequirements for areas prone to these events.We have seen the development of new prod-ucts and the increased use of safety glass tohelp protect homes in the event of a bushfire.”

And when it comes to aesthetics, architects inAustralia have the same interests as those here—they all want to add visual appeal. Decorativeglazing is one way they are doing just that.

“There has been a growing trend for encapsu-lating decorative materials within glass: naturalmaterials, such as flowers and bark; man-madematerials, such as metal meshes, fabric andpaper; graphics, such as digital images and pho-tographic images; as well as colors,” says Finn.“These allow the functional qualities of glass—safety, durability and buildability—to be com-bined with the decorative application.”

He says the current growth for this market isin commercial applications as well as high-end

residential. Not unlike the North Americanenvironment, though, he adds, “These trendsinevitably filter down to more widespread use asmarket awareness grows and manufacturersbecome more comfortable with new techniquesand methods.” AG

PRODUCT DESCRIPTIONSolarphire® AR glass is manufactured by coating Solarphire PV glass on one surface with a durable, high-efficiency, anti-reflective coating. Solarphire 2XAR glass uses the same coating on both surfaces.

Due to the improved transmittance this proprietary coating provides in the visible and near-infrared bands, heat-treated Solarphire AR glass can increase power output for certain photovoltaic (PV) technologies by 2 percent or more when used as a cover plate.

Solarphire 2XAR has even higher transmittance in the same bandwidths. This double-coated product should only be considered for non-laminated applications. Solarphire 2XAR glass boosts power output when used as a cover plate for concentrated PV modules.

Both products process like uncoated glass and do not leave deposits on rolls or belts. For the best optical performance, they should be heat-strengthened or tempered. Stock sheets are available up to 72x90 inches, which can be cut and heat-treated at the fabricator level.

DURABILITYThe IEC 61215 protocol specifies 1,000 hours of damp heat exposure (85°C/85%RH) and 10 cycles of humidity-freeze testing. The anti-reflective coating on Solarphire AR and Solarphire 2XAR glasses has undergone extensive testing, including over one year of damp heat exposure, 60 cycles of humidity-freeze testing, and 17 weeks in ASTM B-117 salt fog testing. The decrease in transmittance (ISO 9050, 400-1100nm) for each test was less than 0.5 percent.
