Green Roof in Ottawa

From Metro News:

Ontario Completes Ottawa Courthouse Green Roof (2012)
"A new green roof at the Ottawa Courthouse will reduce energy costs, improve air quality and help Ontario meet its long-term energy conservation goals.  (The roof's green space is bigger than four hockey rinks put together, or one football field.) 
The Ottawa Courthouse's green roof is a living landscape that supports 60 varieties of plants and protects the building's structure from the elements. There are 26 separate green roofs spanning multiple elevations, for a total of 70,000 square feet of green space that will help keep Ottawa's air clean. 
While a conventional roof lasts only 20 to 25 years, green roofs last at least twice as long. The new green roof will save $23,000 a year in energy costs by reducing summer cooling and winter heat loss by 26 per cent."

I found this after reading about Ottawa investing in solar energy on their municipal buildings:

Ottawa gets green with solar energy project (Metro News, September 2016)

"Eight municipal buildings now equipped with solar panels."
