The Toronto-Dominion Centre (TDC) in Toronto, Canada is opening the door to all things green with the installation of a double-sided living wall by ELT Easy Green. The wall celebrates the launch of the Green Portal, an online environmental management tool for one of Canada’s largest commercial developments.
The TDC is one of North America’s largest business communities with six buildings, 4 million square feet, and 21,000 office employees. Two of the towers have LEED© Canada Gold certification. The living wall installed in front of the Toronto-Dominion Bank Tower features ELT Living Wall Panels, three Rainwater HOG tanks, and a TurboRain solar powered irrigation pump.
The HOGs were the best fit, according to Greg Garner of ELT EasyGreen who managed the installation, because “the shape of the HOGS allowed for them to be placed inside the wall and in the base while keeping the dimensions as small as possible.”
One tank, installed horizontally in the basin, receives the water from the other four tanks (installed vertically side by side) and sends it to the solar irrigation pump. The HOG tanks, which are filled manually to maintain a steady water supply, solved the problem of finding an underground water source. A staff person fills the HOGs for the automatic irrigation system to run every other day.
As for the Green Portal, “The principle that says ‘you manage what you measure’ is now being effectively applied when it comes to sustainability best practice at Canada’s largest office complex,” says TDC General Manager David Hoffman.
The Green Portal shows a real-time dashboard-style display of building energy use for tenants and management to track and compare energy use and consumption among the Centre’s six towers.
