PPG Industries has declared that SOLARBAN 70XL glass has been used to build an energy-saving, sophisticated curtain wall system, which enabled Toronto’s RBC Centre to become Canada’s largest building to receive LEED certification.
Over 420,000 sq.ft of custom curtain wall included in the LEED- Gold winning 43-story tower was designed from Solarban 70XL glass. Upper floors of 1.2 M square-foot tower was sheathed with SOLARBAN 70XL glass, which was also incorporated in the laminated security glass on the lower floors. Maximum daylighting was facilitated by floor-to-ceiling windows. Increased energy-efficiency was provided by the north-south oriented installation of advanced system of sensor-controlled sun shades and automated blinds.
Solarban 70XL glass made its first appearance at the GreenBuild International Conference and Expo in 2005. It is fabricated with the company’s triple-silver coating that assures optimum transparency balance and solar control. Solarban 70XL glass has a standard light-to-solar gain ratio (LSG) of 2.37, resulting from the combined efficiency of 64 % visible light transmittance (VLT) and up to 0.27 solar heat gain coefficient (SHGC).
Designed by Kohn Pedersen Fox Associates, the RBC Centre features a broad range of environmentally advanced systems that contributed to increased energy-efficiency and sustainability features. Compared to other similar buildings, this RBC Centre has demonstrated to conserve 40% on energy costs and 47% on indoor water conservation, thereby promoting its environmental and sustainability features.
