Green Roofs in Copenhagen

Copenhagen is now the first Scandinavian city to put a mandatory green roof policy into action. The new policy requires vegetation and soil to be a mandatory part in architectural planning; in particular, it covers all roofs with a slope less than 30 degrees, plus the refurbishment of older roofs. By putting this new green roof policy into action, it pushes the great Danish city one step closer to reaching their carbon neutral goal by 2025.

Now, as far as the green roofs go, there is a list of specific requirements to consider. Buildings with green roofs must be able to meet at least 2 of the following requirements:

  • The roof must absorb 50-80% of the precipitation that falls on the roof.
  • The roof must provide a cooling and insulating effect of the building and reduce reflection.
  • The roof must help make the city greener, reducing the urban heat island effect, counteracting the increased temperatures in the city.
  • The roof must contribute to a visual and aesthetic architectural variation that has a positive effect on the quality of life.
  • The roof must double the roof life of the roofing membrane by protecting it against UV rays, etc.

Superb initiative by Copenhagen. The green consequences of this requirement are several..

- Architects will have to learn about green roofs to incorporate them in their plans. The knowledge base in green roofing will shoot up.

- Innovation in green roofing (in Copenhagen to begin with ) will increase

- It would inspire architects and city planners in other parts of the planet to look at green roofs and other innovative eco ideas.

    I think this is such a fabulous idea.In the olden days, I remember my granny telling me how her house used to be full of green on top of the roof. Now adays if there is any moss or green on top, everyone just removes it and gets a fresh coat of paint. have to get back to nature! pronto!
