green roofs

Green roofs can help bring back nature to the urban context by replacing the footprint that was lost to development. They introduce needed greenery over unused or underused surfaces, reducing the imperiousness of our urban developments. 

The benefits of green roofs can be ecological, social and economical. For instance, they can bring economic benefits to building owners, as they lengthen the life-span of waterproof membranes on roofs, and can contribute to energy efficiency of buildings. Green roofs also provide recreational, social and therapeutic spaces. Moreover, green roofs improve air quality and reduce surrounding temperatures. When it comes to ecosystem services, green roofs help increase a city’s biomass, reduce and filter stormwater runoff, and provide urban wildlife habitat and biodiversity. Due to these benefits, green roofs can also aid at increasing densification, as they attract workers and residents.
