AUGUST 2019 | 11 RENDERING BY GBL ARCHITECTS/COURTESY ENGINEERED ASSEMBLIES INC.; PHOTOGRAPHY COURTESY GREENSTONE STRUCTURAL SOLUTIONS Building Envelope Another residential project of note for Engineered Assemblies is 8X On The Park in downtown Vancouver, designed by GBL Architects. This 35-storey tower will feature over 31,000 square feet of eight-millimetre (mm) Equitone Tectiva high-density fibre cement. "As was the case with ViewStar, we became involved in this project in the very early planning stages, which was important because the design group developed details and sizes to help maximize the use of the material," says Smith. "Ultimately they wanted a low-maintenance and high-performance facade that made a statement." The design incorporates a stag- gered running bond vertical joint using panels measuring 190mm by 1,500mm, laid out in a horizontal fashion as it climbs up the building. Two different colours within the panel layout accentuate the natural variation within the Tectiva, which has a directional linen sanded finish. Face fastened colour matched rivets will be used to attach the facade panels. "It's a challenging project in that this is a very busy site, so the panels are being pre-cut in Europe and installers Keith Panel Systems and construction manager Ledcor are relying on just-in-time deliveries," says Smith. Greenstone Structural Solutions provides a building envelope that addresses the challenge of thermal bridging. Greenstone ICE Panels [Insulated Composite Envelope] can be used in wall, roof, and floor applications and can be designed to have zero thermal bridging throughout the entire building envelope. ICE Panels were recently utilized in Rankin Inlet, Nunavut – a region with a short construction and materials shipping season. Rodney Penner, sales manager for Greenstone says, "A four-man crew was able to close in the building in 40 days and turn on the heat. Due to the nature of our ICE Panels with their built-in insula- tion and vapour barrier, once the building is erected and windows and doors are installed, the heat can be turned on and construction can continue. "This means that everyone at the post framing stage of construction is working in a controlled environment. This is similar to the idea of constructing modular in a factory. With a controlled environment, there is better quality control, and fewer variables to go wrong, specifically with the building envelope." Greenstone's ICE Panel is an engineered combination of EPS and galvanized steel. This combination results in a much lighter and stronger building envelope. 8X On The Park, Vancouver, B.C.
