PPG glass helps utility operations centre earn LEED certification

SOLARBAN® z50 solar control, low-emissivity (low-E) glass by PPG Industries was used by the Piedmont Natural Gas Operations Center in Nashville, Tenn., earning LEED® Gold certification.

The Piedmont Natural Gas Operations Center in Nashville, Tenn., earned LEED® Gold certification last year, due in part to a comprehensive energy-management system that incorporates SOLARBAN® z50 solar control, low-emissivity (low-E) glass by PPG Industries.
When combined with clear glass in a standard 1-inch insulating glass unit (IGU), steel blue-grey-tinted Solarban z50 glass provides visible light transmittance (VLT) of 51% and a solar heat-gain coefficient (SHGC) of 0.31 that is as much as 23% better than competitive glasses with a similar aesthetic. Solarban z50 glass is part of an energy-management system at the centre that includes an advanced LED (light-emitting diode) lighting system and exterior building shades controlled by the sun’s orientation.
