Case Study

Deloitte Tower

SunGuard AG 50 and SN 68 on Deloitte Tower in Montreal, Quebec.

Monumental glass for a towering monument

Well on its way to becoming a key landmark for the city, Deloitte Tower is situated on a central city site in Montréal, connecting historic Windsor Station to the Bell Centre arena. The modern curtain wall-encased tower includes 26 stories of office space, with Deloitte as its lead tenant.

  • Montreal, Quebec Location
  • Office/Mixed Use Building Type

Deloitte Tower is Montreal’s first LEED® Platinum office development, expected to reduce energy consumption by 30-40 percent versus a conventional office tower. The building is also participating in Cadillac Fairview’s nationwide Green At Work® program that tracks energy use, water consumption and waste diversion, establishing reduction targets for each year.

Contributing to that energy efficiency is high performance, low-E Guardian SunGuard® coated glass. Virtually the full width and more than 80 percent of the height of the perimeter wall on all office floors at Deloitte Tower, SunGuard AG 50 coated glass and SunGuard SuperNeutral® 68 coated glass permit daylight harvesting, significantly reducing power consumption and contributing to the overall comfort of occupants. The more than 250,000 square feet of exterior glass includes unusually shaped, 5x8’ ultra-wide lites transitioning the retail spaces – on the first floor on the south façade and fourth floor on the north – into the rising façade. SunGuard SuperNeutral 68 coated glass on the retail glass maximizes visible light transmission, while SunGuard AG 50 coated glass on all remaining exterior glass offers more solar heat management with clear views for those occupying the office spaces.

Deloitte Tower was honored with the following awards:

  • 2014 Trophée Chantier d'importance - L’Association de la construction du Québec (ACQ)
  • 2015 Amatura Award - Jury's Favorite - Institut d’acier d’armature du Québec (IAAQ)
  • 2015 Excellence in Real Estate - Commercial - Urban Development Institute of Quebec

The Guardian SunGuard coated glass product line for commercial applications offers excellent solar control and a wide variety of colors and performance levels. SunGuard glass products create value through innovative, leading solutions for appearance, economics and energy efficiency, and are available through an international network of independent Guardian Select® fabricators.

Architects and designers utilize the industry-leading Guardian Glass Analytics™ for North America for comprehensive engineering and analytical modeling and custom glass content that demonstrate the advantages of high performance glass in building facades.
