Green roofs are on the agenda worldwide as part of a growing effort to meet the challenges that we face, including climate change, denser cities and the need for healthier neighbourhoods.
Strolling through Copenhagen, you may have encountered one of the 40 green roofs nested around the city. Coming in all scales and sizes, from cycle shelters, to schools and mixed use buildings to landscapes above underground garages, green roofs provide a unique opportunity to transform traditional surfaces into green life-giving oases. They lead to larger quantities of rainwater being absorbed in a sustainable way and can curb the rise in temperature at the same time. They also create habitats for animals and plants.
Green roofs policy and planning in Copenhagen
Back in 2008 the City of Copenhagen began focusing on alternative ways to handle rainwater and the Wastewater Plan 2008 became the first plan document that included approaches in that direction. In 2009 Denmark was in charge of the UN Climate Change Conference COP15 which defined the framework for the strategies that could be implemented to meet the challenges of climate change. During that period, the focus on green roofs intensified setting a goal for urban design with green roofs in the Climate Plan of the City of Copenhagen.
Since then Green Roofs have become integrated in different guidelines such as the guidelines for Sustainability in constructions and civil works, which mandates green roofs for all the municipalities buildings. Green roofs are also a part of the city’s Strategy for Biodiversity. Since 2010 green roofs are mandated in most new local plans. A calculation based on approved new local plans mandating green roofs gives a total of 200.000 m2 of green roofs to be installed.
