The new 31-story tower will rest partially on top of and it will stand partially alongside the existing Old Stock Exchange Building. The Stock Exchange building will be completely renovated and incorporated into the new development, and it will become Canada’s first LEED Platinum heritage conversion. The project, which is already being described as Canada’s largest green office building, will feature a variety of energy-saving technologies.
Shading louvres will be incorporated into the facade, preventing direct sunlight from hitting the building’s windows, and reducing the need for air conditioning. The building will also feature a high-efficiency hydronic heating and cooling system. Solar thermal panels will provide hot water, and the building will feature a stormwater retention and reuse system. Inside, the building will feature lush landscaped sky gardens for workers to enjoy.
Overall, the building’s green features are expected to result in 50 percent less energy use, which will translate to a 35 percent reduction in energy costs. Construction on the $200-million building is scheduled to begin in October, and the project is expected to be completed in 2017.
