Greenbuild 2013 Settles in Pennsylvania, Bringing New Glass Innovations
The Pennsylvania Convention Center in Philadelphia will go green November 20-22. Not literally, of course, but an anticipated 30,000 attendees and 900 exhibitors from the green building industry will gather there to do business. More than100 educational sessions are planned, including world-recognized speakers, LEED workshops, off-site educational sessions, and green building tours of local sites. This year’s speaker lineup includes a keynote by former Secretary of State Hillary Rodham Clinton and closing plenary speech by noted author and statistician Nate Silver.
The trade show floor will be the big draw for many. Here’s a sampling of those that will be there with some of their newest green glass and glazing developments.
doors and windows
The Renovate window retrofit technology by J.E. Berkowitz uses an interior glazing method of hermetically sealing a factory-made insulating glass unit (IGU) to the existing monolithic glass window with a warm edge spacer. The system maintains the look of an existing exterior building façade, affords significant energy savings, improves STC and contributes to LEED points, according to the company, which also says the system offers a lower-cost alternative to a complete window rip-out and re-glaze. www.jeberkowitz.com

SunGuard SNX 52/23 is a new commercial glass product from Guardian that combines light transmission, low solar heat gain and low reflectivity for commercial applications. Using triple silver technology, SunGuard SNX 52/23 was developed to meet energy codes by delivering a SHGC of less than 0.25 while still appearing like clear glass, the company says. SNX 52/23 has a neutral blue tint. www.guardian.com
Singing the Blue-Grey Blues – Booth #3928
The new graphite blue tint offers flexibility for original and innovative architectural designs where low reflection is required. It is also suitable for commercial applications requiring solar control. To achieve additional thermal insulation, the new tinted glass can be combined with the company’s Energy Advantage™ low-E glass in an insulating glass unit. www.pilkington.com/na
A new storefront system will be available in Tubelite’s booth. The TU24000 series is designed to help commercial buildings meet energy conservation needs. The high-performance storefront system is part of the company’s Therml=Block product offering and features an additional pour and debridged thermal break pocket to withstand demanding climates and conditions. The glass is centered in the 4.5-inch-deep system. TU24000 is recommended for low-rise buildings and the lower floors of high-rises. www.tubeliteinc.com
For shape design flexibility, SageGlass is available in trapezoid, parallelogram and triangular forms, in addition to the wide variety of standard rectangular glass sizes. While getting accurate and uniform tint levels across odd shapes can be a significant engineering challenge, the company says its shape options have already been field-proven in a number of building projects including the Utrecht Government Building in the Netherlands, the National Research Energy Laboratory in Boulder, Colo., Cottage Grove City Hall in Cottage Grove, Minn., and the Immanuel Bible Church in Springfield, Va. www.sageglass.com
See Things in a New Light(-Gray) – Booth #642
A new light-gray base color for the Suntuitive® interlayer is now available from Pleotint LLC that the company says offers improved compatibility with glass tints.
The Suntuitive interlayer is a thermochromic interlayer for laminated glass that gradually darkens in response to rising temperatures caused by direct sunlight, then cools as the sun moves across the sky, returning to a clear, neutral state in cloudy or dark environmental conditions. It requires no mechanical or electrical intervention, eliminating threats of failure caused by temperamental computer systems or faulty wiring, the company says. Installation of windows with the Suntuitive interlayer is the same as other traditional window systems. www.Pleotint.com
air barrier systems
Dow Corning® will showcase its collection of silicone solutions designed to improve the energy efficiency of buildings and enable greater design freedom, according to the company. The company’s silicone air barrier system is a suite of compatible, high-performance silicone technologies designed to work together to protect the entire building envelope and to improve the energy efficiency of buildings. It delivers airtightness, UV resistance, weatherability, breathability and fire ratings, according to the company. The system includes the company’s DefendAir 200, a 100-percent silicone liquid-applied air and weather barrier; the company’s silicone transition system with high-performance, pre-cured 100-percent silicone rubber strips and corners that install using the company’s silicone sealants (rather than mechanical fasteners) to form a continuous airtight transition from the window to the wall. The company also offers its silicone sealants, which are compatible for use with the components of the barrier system.
