Benefits

Improve Air Quality
Green roofs effectively improve air quality in cities by increasing oxygen production, lowering air temperatures and filtering contaminants.  Contribute to a reduction in greenhouse gas emissions and aid in ozone protection.

Capital Cost Savings
Green roofs enhance a building’s energy performance and cost saving come from the reduction in cooling and heating requirements

Habitat Creation in the Urban Landscape
In addition to the beauty that living, breathing plants add to any space, the biodiversity of vegetation provides rare habitats for butterflies and birds in the city.

Reduction of the Heat Island
The urban heat island (UHI) is the increase in temperature in urban centres.  Green roofs are an antidote to the vast dark surface area such as roofs or pavement.

Storm water Reduction
Green roofs absorb up to 80% of an area’s rainfall, minimizing demands on municipal infrastructure and improving storm water management by reducing the risk of combined sewer overflow.

Reduced Noise Levels
Planted areas are natural sound insulators and absorb more sound than hard surfaces.
