Stepping off the hoist elevator, we're high above the streets of Toronto's Financial District, with Nathan Phillips Square a miniature diorama to the north. We're on the 40th floor of the EY Tower, where glazing is now being installed as the curtain wall begins to reach the distinctly shaped roof.
Concluding our three-part series, UrbanToronto's EY Tower tour ends with a walkthrough of the 40th floor and mechanical penthouses above, where the roof's crystalline form is now taking shape. Last week, our coverage began with a tour of the tower's office levels, followed by an in-depth look at the replicated Concourse Building heritage facade at the corner of Adelaide and Sheppard Streets below.
Designed by Kohn Pedersen Fox Associates in partnership with Toronto-based WZMH, Oxford Properties' 40-storey tower joins the heart of the Financial District, with First Canadian Place—still the country's tallest building—immediately to its south, with INDX Condos now nearing completion just to its northeast. Amidst this dense cluster of rectilinear skyscrapers, the skeleton of EY Tower's angular and slightly dramatic roof already stands out.
As the curtain wall is installed, the tower's presence will become more defined, with the building envelope promising to accentuate the tower's unique form. Notably, the glazing will envelop the entirety of the mechanical penthouse. The aesthetic continuity allows the roof to be a prominent architectural feature, which will be highly visible from Nathan Phillips Square.
Touring the recently topped-off building with construction management company PCL, the roof's steel skeleton is being assembled as we reach the roof. Overseen by Hamilton-based Walters Inc., the structural steel installation is one of the most complex stages of construction, PCL's Mike Jackson explains. Structurally designed by Stephenson Engineering, the complex web of steel atop the two-storey penthouse required extensive computer modelling, requiring further coordination to facilitate Oldcastle Building Envelope's curtain wall installation on the roof's unique skeleton.
The mechanical penthouse will house the requisite elevator overrun and HVAC equipment, including a rooftop chiller plant. Below, the 40th floor will terminate at a green roof at the tower's south elevation on Adelaide Street. The showpiece roof will be lit—by what is being described as a 'lantern light'—through a monochromatic LED installation, discretely drawing attention to the tower's architectural character.
At the lower levels, another green roof will top the sixth floor amenity terrace. Alongside the highly efficient curtain wall, the tower's sustainability features include solar fins, fully integrated systems, and locally sourced building materials. The tower targets LEED Platinum certification, aiming to be among the most energy-efficient properties in the city.
Over the coming months, the installation of glazing throughout the mechanical levels will aesthetically complete the tower's exterior, while interior work will continue through to 2017. The building targets an early 2017 completion, with occupancy expected by February.
