The Prestige window film series from 3M is the first clear and non-metal based window films to significantly reduce heat and UV rays entering residential or commercial buildings, according to the manufacturer. The absence of metal prevents against corrosion on the film and eliminates interference with wireless and cellular signals. During summer and in warmer climates, the Prestige Series blocks up to 66 percent of heat penetrating the window.
3M’s new Prestige Ultra Safety & Security film adheres to the window to hold shattered glass in place in the event of impact. It also makes the glass harder to break in the first place — ideal for storm-prone locations and even street-level urban environments subject to vandalism. The metal-free film, which utilizes nanotechnlogy, has a reflectivity almost on par with glass, yet blocks 99.9 percent of UV rays to offer up to SPF 1000 protection.

Crestline has introduced Earthgard, an environmentally-friendly window component engineered from straw fibers, North America's largest renewable resource. This fiberboard contains only non-toxic resins, is dimensionally stable, and will not warp.
A new generation of window films offers enhanced clarity and visible-light penetration while better mitigating heat and glare. Films that utilize metal nanoparticles to block the sun are among the most effective. “Measured in a billionth of a meter, nanoparticles are small enough to see through, but large enough to absorb wavelengths of energy from the sun,” explains Thomas Hicks, president of Portland-based Energy Film. In addition to selling view-control films, the company markets an energy-saving product that boasts year-round benefits. Energy Film has been certified to block 97 percent of UV rays and 70 percent of thermal infrared light, thwarting heat gain in the summer and retaining warmth in the winter. The product affixes to glass via cohesion and atmospheric pressure rather than traditional adhesives; once attached, the film sticks indefinitely until removed, and leaves behind no residue. Such user-friendliness makes for a more forgiving installation.

The mask used to create each design is water soluble and removed using water alone. The doors are available in standard sizes up to 4' x 10' and with 45-, 60-, 90-, and 180-minute UL fire ratings.
Now available in North America for both residential and commercial projects, IQ Glas is a heated-glass window system that has been available in Europe for more than 17 years. IQ Glas features a double-pane structure that allows radiant heat to warm sunroom, conservatories, indoor swimming pools, and other rooms that are difficult to heat efficiently with traditional convection heating. The inner pane has a thin metal-oxide coating that helps disperse heat equally, while the outer pane has a special coating that keeps heat inside while repelling cold air. Between the two panes, an inert gas enables the system to achieve high levels of thermal insulation (.14 U-Value), even though the temperature of the windowpane never exceeds body temperature. The manufacturer claims the main advantage of the product over traditional heating methods is the ability to keep dust circulation to a minimum, ideal for anyone suffering from asthma or allergies.

Custom colors, smooth or bumpy textures, and color gradations are available.
Greenlite Glass Systems Inc.
Introduced to the North American market last June at the AIA show in Miami, the GlassX glazing system incorporates a salt hydrate phase change material (PCM) that stores energy from the exterior temperature and reuses it to either heat or cool the building as needed, putting less pressure on the mechanical HVAC systems. Achieving U-values up to 0.08, GlassX is a quadruple glazed sealed unit that is made up of three separate insulating glass units (IGUs), a prismatic solar filter that deflects high angle sunlight, two low-E coatings, and a PCM core. “GlassX would have a similar R-value to something like concrete, which is pretty much unheard of in the glass façade arena,” says Ryan Dennett, President/CEO of Greenlite Glass Systems, the exclusive distributor of GlassX in North America.
According to Dennett, GlassX not only meets but exceeds the requirements of current building energy code standards. ”People thought at one stage that glass buildings would be a thing of the past because you were going to have to have a concrete building with little punch out windows it in. GlassX allows you to still have that glass façade and include visionless, spandrel areas that will still let light through but will meet the new standards for heat loss in buildings.” As it is translucent and not transparent, in either its solid or liquid state, the glazing is better suited for spandrel and lower transom applications.
The salt hydrate in the PCM is specifically formulated for the building market to melt and freeze within a narrow range that is close to room temperature. The .8''-thick section of the PCM can store as much heat as 9'' of concrete; it will then release that constant heat at a rate of 16 to 30 BTUs over a 20 hour cycle. Depending on the usage and the amount in the building, interior temperatures can be reduced by 4 to 6 degrees Celsius in the summer months. “You can think of the PCM as an ice cube for a building that doesn’t melt,” says Dennett.
Developed in Switzerland over a decade ago and used in many European buildings, the glazing is now being considered for projects in North America. In comparison to $20-$30 a square foot for typical triple glazed IGUs, GlassX costs about three times as much, averaging $60-$90 per square foot. “But you are looking at a pay back time of 5-10 years given your upfront savings in HVAC systems and long term energy savings,” says Dennett.
One of the architecture firms currently considering GlassX for an upcoming project is SRG Partnership in Seattle. According to Project Designer Christopher Colley, SRG is possibly using the glazing for a new nursing and health science building for Everett Community College in Washington state. While the product’s newness and cost may be hurdles, particularly for publicly bid projects, Colley thinks it is an intriguing new option for spandrel glass as his firm starts to design buildings for The 2030 Challenge. “This a product that can potentially allow us to have more design freedom and still have a very high performing building.”
The Burj Khalifa’s 2,650'-tall, 160-story facade is veiled in 26,000 glass panels — tallying more than 1.8 million square feet of glazing — supplied by Guardian Industries. The company’s SunGuard Solar Silver 20 and ClimaGuard NLT Low-E glass series both offer strong solar and thermal performance, antiglare properties, and enhanced light reflectance to withstand the desert climate’s extreme temperature swings, strong winds, and blazing sunshine.
Known for their high-end bathroom fittings and fixtures, Hansgrohe will soon make a new name for itself in the U.S. — if everything goes to plan. Scheduled to be available for U.S. projects in about a year and a half, the AquaCycle 2500 system, developed by the Pontos division of Hansgrohe, turns bath and shower wastewater into hygienically clean gray water.
“The hold up right now is that the codes in each state are different regarding gray water and it would be very challenging to bring this product to market at this point,” says Nicolas Grohe, director of marketing and product development for Hansgrohe, North America. While U.S. code authorities determine how clean recycled water needs to be, “there are no standards or codes in the U.S. now for what is gray water,” says Lars Christensen, senior product manager with Hansgrohe. In the mean time, interested U.S. architects can specify the system for their European projects.
So how does the Pontos AquaCycle 2500 work? The fully automatic system uses a biomechanical treatment method, without any chemical additives, to transfer water that usually goes down the drain into water that can be reused for toilet flushing, cleaning buildings, or irrigation. First, a filter removes coarse particles from the incoming gray water, then the water undergoes a two-stage biological treatment, where a supply of atmospheric oxygen and microorganisms degrade the contaminants in the water, such as soap and shampoo. The water is then disinfected through the use a UV lamp and stored in the process water tank until reuse. Sediments generated during the biological treatment are automatically removed and conducted into the drains. If insufficient process water is available it is initially tapped up with rainwater, and only when there is no rainwater available is the tank tapped up with drinking water. If too much water is generated, it is fed via an overflow pipe into the wastewater drain to prevent an overflow of the system. According to Grohe, it takes approximately four to eight hours for the wastewater to become reusable gray water
The 2500 model, the latest in the line, is a combination of several other systems the company has been manufacturing since 2001. The system has been enhanced by the addition of a rainwater harvesting system that helps supply water in case waste water supply is low and an advanced heat recovery system that uses the gray water’s thermal energy to pre-heat incoming clean water, saving energy and expense. While Grohe says hotels, high rise condominiums, and schools are the main markets, he sees potential in any project with enough showers, lavatories, and toilets. He cites one inspired application where a public pool in Yerres, France, recycles shower wastewater to supply water for the city’s street cleaning trucks.
According to Grohe, AquaCycle is not intended to be money maker for the company, but it is something they felt compelled to invest in. “Although the product is not offered [yet in the U.S.], we want to talk about it and generate interest because we believe it’s the right thing to do.” Hansgrohe Inc., Alpharetta, Ga.

Other ocean-inspired tints include the light green tranquility of Solexia glass, emerald-green Atlantica glass, and aqua-blue Azuria glass. The solar control performance of Oceans of Color can be further enhanced by combining these individual tints in 1'' insulating units with Sungate100 Low-E glass or Solarban 60 solar control Low-E glass.
November 2009 updated
PPG Industries has introduced Vistacool Azuria glass, a subtly reflective, color-enriched architectural glass that gives a luminous aqua-blue appearance while transmitting high levels of daylight. The glass was developed to fulfill requests for a tinted high-performance architectural glass with high visible light transmittance (VLT) and a reflectivity that is more muted than the mirror-like finish of traditional reflective glass. Vistacool Azuria has a VLT of 52 percent, roughly twice the average of other reflective, coated, tinted glass products on the market.
Solarban z50 glass, the latest addition to PPG¹s line of Solarban solar control Low-E glasses, features a cool steel-blue gray appearance, minimal exterior reflectance, and comfortably bright levels of visible light. When combined with popular tints from the PPG Oceans of Color collection of spectrally-selective tinted glasses, Solarban z50 glass dramatically expands the aesthetic and performance options available to architects.
PPG has introduced a new high-performance glass combining the industry-leading solar control performance of Solarban 80 low-E clear glass with the company¹s new blue-green Optiblue glass. The result is an architectural glass with a metallic gray-green exterior tint and a neutral gray interior appearance. In a standard 1'' insulating glass unit, Solarban 80 Optiblue glass produces a solar heat gain coefficient of .23 and visible light transmittance of 34 percent. This results in a light-to-solar gain (LSG) ratio of 1.48, which exceeds the U.S. DOE¹s 1.25 LSG threshold for spectrally selective glass.
PPG Industries’ performance glazings business has launched the dark-blue Pacifica and light sky-blue Solarblue glasses, two new blue-tinted glass options. Both may be combined with Solarban or Sungate 500 coatings to maximize energy efficiency. Three additional tints can be specified by adding Solarcool reflective coatings to Pacifica and Solarblue glasses with solar heat gain coefficients ranging from 0.32 to 0.25, or by combining Pacifica glass with subtly-reflective, color-enriched Vistacool coating, yielding a solar heat gain coefficient of 0.27.

Vision, a range of high-precision fabrics, is produced from black synthetic fibers coated on one side with a thin layer of metal that can be used in combination with laminated glass or acrylic for walls, partitions, doors, and other surfaces. When used in a facade, such as this office in Madrid, the outer metal surface helps reduce solar heat gain, while the inner surface reduces glare without hampering views.
November 2009 updated
SageGlass products have the ability to tint and untint at the touch of a button, subtly adjusting to occupants needs. This functionality helps reduce energy bills by controlling solar heat gain and increases worker productivity by allowing additional daylighting, minimal glare, and enhanced occupant comfort. The glass is currently offered in Classic, Sea Green, Cool View Blue, and Clear-as-Day Gray.
For a decade, the owner of an office building in Greenwich, Connecticut had to drape a blue tarp over the building’s top-floor skylight in order to cope with unwanted solar heat gain and glare. Replacing the old skylight with Sage Electrochromic’s electronically tinting glass allowed the tenant to keep the natural light, while maintaining some control. A 14’’ PV strip installed on the exterior along the bottom of the skylight powers the glass.
Serious Materials, the Sunnyvale-California based developer and manufacturer of sustainable green building materials, has introduced ThermaProof, a new line of windows they claim will offer the highest full-frame R-values in the world. ThermaProof is a complete family of windows for residential and commercial construction that offer R-values at R-8, R-11, or R-14 across the entire glass and insulated frame rather than just at the center of the glass. This helps reduce a typical building¹s heating and cooling energy use by 20 to 40 percent, resulting in an 8 to 16 percent energy savings. Most building owners will see a return on investment in anywhere from one to five years; while some might see a return in as little as nine months.
To drive up the R-value of the window the manufacturer includes one, two, or three layers of mylar to reduce the amount of convection and air flow in the window cavity. In addition, a brand new spacer technology holds the glass panes apart from each other to create a large insulating gap. A wet seal is used to place the glass in the frame, rather than a dry seal, meaning no heat or cooling loss. A new framing system ‹ foamed PVC for residential and insulated fiberglass for commercial ‹ insulates the frames as well as the glass (unlike aluminum frames). Finally, a ³triple fin² weatherstripping seals everything tightly. Styles available include double-hung, single-hung, slider, casement, sliding doors, French doors, and storefront. Curtainwall framing is not currently available but will be in the future.
Simonton Windows introduces a new series of injection-molded geometric-shaped windows in the ProFinish product line. The frame of the octagon-, circle-, and oval-shaped windows is made in one piece in a customized mold. Each unit features a standard 1'' Insulated Glass Unit with a Super Spacer for high energy efficiency.
Solatube International is based in Vista, Calif. where its tubular skylight and solar-powered attic ventilation products are produced for worldwide distribution. Solatubes can be used to earn or contribute to the following LEED certification credits: Daylight Credit; Energy Optimization Credit; Recycled Content Credit; Regional Credit; System Controllability Credit; and Innovation in Design Credit.
Unlike passive skylights, the ADS-600 active daylighting system employs a mirror array that tracks the sun precisely throughout the year, directing light from the brightest part of the sky down and into interior spaces. The mirrors conduct low-angle sunlight efficiently, and also shade the intense light sometimes found at high sun angles. The system runs on energy generated by a single photovoltaic cell.
For many locations, the use of interior window film is not logistically feasible. While film affixed to the facade is one alternative, exterior applications typically degrade faster in the elements. Solutia has solved that problem with its Vista exterior film. Engineered for use where interior application is impractical or not technically viable, the product rejects up to 83 percent of solar energy, the manufacturer claims. Enhanced durability comes courtesy of a nonstick, highly scratch-resistant hard coat that also renders windows easier to clean. Dirt and pollutants can be washed away with water.
The GREENGUARD Environmental Institute (GEI) has certified that Special-Lite entrance products meet the GREENGUARD Product Emission Standard for Children & Schools, the most rigorous product emissions criteria to date. Special-Lite doors and frames were the first commercial door and frame products to achieve GREENGUARD Certification, and are also the first to meet the stringent new Children & Schools Standard that ensures low emission levels for volatile organic compounds (VOCs).
Suited for residential and commercial applications, Bendheim’s Color Coated EcoGlass contains 60% recycled material.

The exterior curtain wall for the 55-story Bank of America tower at One Bryant Park, designed by Cook+Fox Architects, features clear PPG Starphire glass. Viracon applied a low-e coating and frit and turned the glass into an IGU installed by glazing contractor Permasteelisa. The ceramic fritting on the glass helped the architects control glare and meet the building’s stringent LEED Platinum energy requirements.
VT Industries has been awarded Forest Stewardship Council (FSC) certification that qualifies the company as a provider of certified wood doors. This certification is awarded by the SmartWood Program of the Rainforest Alliance, an FSC accredited certifier. Before receiving its chain-of-custody certification under the FSC system, an on-site evaluation was conducted by a SmartWood assessor of the VT manufacturing facility in Holstein, Iowa. The evaluation was designed to verify that storage, manufacturing procedures and inventory systems segregate certified and non-certified products. In order to maintain its certification, VT will annually undergo an audit to show they are maintaining these standards.

Wausau Window and Wall Systems
September 2005 updated
Planned to be the greenest building developed by California State, Sacramentos Capitol Area East End Complex needed to comply with, or exceed the standards set by Calfornia Building Code Title 24 for energy efficiency and green buildings. To help achieve the States goal, the design/build team integrated Wausaus energy-efficient windows and curtainwall into the facade to maximize the use of daylight.
Wausau has teamed with SAGE Electrochromic glass to offer Sage Glass electronically tinted windows. Now available on a limited basis for commercial, institutional, and healthcare buildings, the windows help control glare, reduce heat gain, and block ultraviolet rays, while increasing the benefits of daylighting and maintaining a connection to the view outside. SAGE produces SageGlass lites by coating float glass with several layers of invisible ceramic material, then fabricates these coated lites into IGUs. Wausau then glazes the IGUs into its aluminum framing systems. Once shipped to the site, the windows are installed into the buildings electrical system and are operated individually by the occupant or automatically by the energy management system.
