I'm sharing some green roof news from downtown Ottawa! A new green roof has been installed at the Ottawa Courthouse. There are 26 separate green roofs spanning multiple elevations, for a total of 70,000 square feet of green space. The Ottawa Courthouse's green roof supports 60 varieties of plants and protects the building's structure from inclement weather.
It has the potential to reduce energy costs and improve air quality. A conventional roof lasts only 20 to 25 years, while 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.
