Toronto opens City Hall Podium Green Roof
Mayor David Miller, together with Deputy Mayor Joe Pantalone and Councillor Kyle Rae, officially opened the City Hall Podium Green Roof on the first day of Doors Open Toronto 2010. According to a City of Toronto release, the event was attended by thousands of visitors, featuring plenty of live entertainment.
“I'm tremendously pleased that we have been able to re-open and re-invent the podium for public use,” said Miller. “The landscaped gardens, a courtyard framing the Council Chamber, a podium terrace and new walkways and furnishings are a spectacular testament to Torontonians' passion for green spaces and their commitment to environmental sustainability.”
“This is a proud day in the history of City Hall,” said Pantalone. “We now have a new park for walks, talks and escapes in the middle of downtown Toronto. Not only is this place a park, but it also helps to reduce our carbon footprint, and it's just stunning.”
Additional environmental benefits of the new green roof on City Hall include a reduction in stormwater runoff, improvements in thermal and sound insulation at City Hall, improvements in air quality and reduction in the building's contribution to the urban heat island effect and its associated cooling costs, and an increased lifespan of the roof's membrane by reducing thermal contraction and expansion.
Approximately 3,250 square metres of concrete on the podium roof has been transformed into living vegetation to reduce the building's environmental impact. The podium roof was planted using a pre-vegetated, modular green roof system.
