Feb. 29, 2012 – PPG Industries has announced that Solarban 70XL glass is part of an advanced, energy-efficient curtain wall system that recently helped RBC Centre in Toronto become the largest building in Canada to earn LEED certification for new construction.
The 43-story tower, which earned LEED certification at the Gold level,
features more than 420,000 square feet of custom curtain wall fabricated
from Solarban 70XL glass on the upper floors and laminated security
glass on the lower floors. Floor-to-ceiling windows maximize
daylighting, while the building’s north-south orientation and a
sophisticated system of sensor-controlled sun shades and automated
blinds limit heat gain and promote energy performance.
Introduced in 2005 at the GreenBuild International Conference and Expo,
Solarban 70XL glass is engineered with a proprietary triple-silver
coating that delivers an optimum balance of transparency and solar
control. With visible light transmittance of 64 per cent and a
solar heat gain coefficient of 0.27, Solarban 70XL glass has a
light-to-solar gain ratio of 2.37 that remains competitive even six years after its introduction.
The RBC Centre, designed by Kohn Pedersen Fox Associates, incorporates a
comprehensive array of environmentally advanced systems to reduce
energy use and promote water conservation. As a result, the building is
projected to realize savings of 40 per cent on energy costs and 47
per cent on indoor water compared to similar structures of its size and
type.
