Solarban 70XL Starphire glass, one the industry’s highest-performing solar control, low-emissivity (low-e) glass products, is part of an integrated energy-management system that incorporates high-efficiency heating, ventilation and air-conditioning (HVAC) systems, solar power for electricity and hot water, exterior overhangs, and a green roof system that reduces the center’s heating and cooling demands.
Made with a triple-silver coating on a low-iron glass substrate, Solarban 70XL Starphire glass offers an exceptional balance of transparency and solar control. In a standard 1-inch insulating glass unit, it has visible light transmittance (VLT) of 64 percent and a solar heat gain coefficient (SHGC) of 0.27, which produces a light-to-solar-gain (LSG) ratio of 2.37.
Although Solarban 70XL Starphire glass was specified throughout the center, it is featured most prominently in Freedom Hall, the building’s central orientation point, which is topped by a 67-foot-high, 50-by-50-foot glass and limestone lantern. Solarban 70XL glass enables daylight from the lantern to flood the core of the building and to appear as a soft-glowing beacon that is visible from Dallas at night.
Seal Grip priming products and Pure Performance paint by the PPG PITTSBURGH PAINTS® brand are featured in the center’s replica Oval Office, where they cover the walls, millwork and trim. Pure Performance paint is a zero-volatile organic compound (VOC) premium latex interior paint. Seal Grip priming products meet VOC-compliance standards for the South Coast Air Quality Management District (SCAQMD), Lake Michigan Air Directors Consortium (LADCO), California Air Resources Board (CARB), Super-Compliant Architectural/Industrial (AIM) Coatings and the Ozone Transport Commission (OTC).
Coraflon ADS coatings color and protect the center’s exterior metal trim and doors. These next-generation low-VOC coatings retain color and gloss longer than conventional coating systems, and they resist chalking and repel surface dirt to reduce cleaning cycles.
The George W. Bush Presidential Center was designed by Robert A.M. Stern Architects, New York. Along with high levels of daylighting and reduced energy use, the 226,000-square-foot building incorporates low-VOC-emitting materials to promote indoor air quality and regionally sourced materials.
